Myths lie at root of native, exotic plants

Written by
Yew Dell Botanical Gardens

Amur honeysuckle, burning bush, ‘Bradford’ pear ... a few poster children for the invasive exotic plant debate. The debate has raged for decades.  But it is often myth that fuels the dissension.

But before we dispel some myths, how about a few definitions?

Conn. trying to contain tree-eating borer

By QUANNAH LEONARD, Republican-American of Waterbury

Piles of ash bark cushioned the feet of state workers inside a state garage on Middlebury Road on a recent day. The men and women used draw knives to slowly peel back bark on bolts of ash trees, looking for signs of a tiny green beetle.

Their work began at the beginning of February, and will continue for at least one more session this month. They want to determine just how long and far the emerald ash borer has infested the woodlands of Connecticut.

The answers will help federal and state agencies, plus municipalities, work together to reduce the spread of this bug.

With each strip of bark, the workers uncovered a pale canvas that can potentially show a history of the highly mobile critter. They are peering for a tell-tale sign — serpentine tunnels left by the larvae as they eat.

Last summer, the bug was first found in the Nutmeg state in Prospect. Since then, it has been confirmed in Beacon Falls, Bethany, Naugatuck and Waterbury. The critter is an invasive species native to Asia that measures a half-inch long.

The infestation threatens Connecticut's valuable stands of ash trees, and experts say could present a threat to public safety.

Invasive species threaten Wisconsin trees 

By Sarah Eucalano
The Badger Herald

Madison has begun testing trees for emerald ash borers, an invasive Chinese insect that has been devastating much of North America’s ash trees.

Ald. Scott Resnick, District 8, said around 25 percent of Madison’s trees are ash trees, adding it will cost the city millions in order to fully cover the incurable disease, which causes ash trees to slowly rot and die. ...

Ken Raffa, a UW etymology professor, said the main emerald ash borer infestation is in Detroit and has been in the United States for 12 years. Having infested the southeastern part of Wisconsin, including parts of the Milwaukee area as well as areas surrounding the Mississippi River.

Raffa said in China the insects do not kill healthy trees, but only sick or old trees that do not have defenses. He said China’s ash trees have good defenses against emerald ash borers, which North American ash trees do not have. “There is no evidence any of the ash trees in the eastern half of the United States having any resistance,” Raffa said. ...

Massachusetts Officials Announce Quarantine to Halt Spread of Emerald Ash Borer

DALTON, MA – Thursday, February 21, 2013 – Officials from the Department of Conservation and Recreation (DCR) announced today that a quarantine will be established in Berkshire County, in order to stop the spread of the invasive insect species Emerald Ash Borer (EAB). This decision comes after extensive survey in the affected area and public hearings.

The quarantine will take effect March 1, 2013.

EAB was first detected in Massachusetts in Dalton in August of 2012. Massachusetts is the eighteenth state discovered to have EAB within its borders. ...

The quarantine order means that certain products will be regulated from moving outside the regulated area, including all hardwood firewood (any piece of wood smaller than 48”), all ash nursery stock, and any ash lumber that has not been treated. Proper wood treatments include the removal of bark and half an inch of wood, dry kiln sterilization, fumigation, and heat treatments.

The State of New York recently added 22 new counties to their EAB quarantine, including counties that abut the Berkshire County border. This will allow wood to move from quarantined county to quarantined county, including moving regulated wood from Massachusetts to the mills that are just over the border in New York, relieving some of the financial pressure on the wood industry in Berkshire County.

CT Offers Tips to Limit Spread of Invasive Species

zebra_musselsThe Connecticut Department of Energy & Environmental Protection (DEEP) and the Lake Zoar Authority will be monitoring local boat launches for the presence of invasive plants and animals, such as zebra mussels.

Zebra mussels were discovered in Lake Zoar and Lake Lillinonah in October 2010. This is the first new report of zebra mussels in Connecticut since 1998, when they were discovered in East and West Twin Lakes in Salisbury....

Actions anglers and boaters must take to prevent the spread of invasive plants and animals, including zebra mussels, are as follows:

Before leaving a boat launch, clean all visible plant, fish, and animals as well as mud or other debris. Do not transport them home. Drain all water from every space and item that may hold water.

At home or prior to your next launch, dry anything that comes in contact with water (boats, trailers, anchors, propellers, etc.) for a minimum of 1 week during hot/dry weather or a minimum of 4 weeks during cool/wet weather. If drying is not possible, clean your boat prior to the next launch.

When fishing, do not dump your bait bucket or release live bait. Avoid introducing unwanted plants and animals to the water. Unless your bait was obtained on site, dispose of it in a suitable trash container or give it to another angler. Do not transport fish, other animals or plants between water bodies. Release caught fish, other animals and plants only into the waters from which they came.

The techniques listed below are for decontaminating your vessel:

Wash your boat with hot, pressurized water.

Dip equipment in 100% vinegar for 20 minutes prior to rinsing.

Wash with a 1% salt solution (2/3 cup to 5 gallons water) and leave on for 24 hours prior to rinsing.

“Wet” with bleach solution (1oz to 1 gallon water) or soap and hot water (Lysol, boat soap, etc) for 10 minutes prior to rinsing.

Tribes Lead Cultural Preservation Threatened by Invasive Species

By Sharon Lucik, APHIS Public Affairs, on the USDA Blog

The emerald ash borer beetle (EAB) is responsible for the death and decline of tens of millions of ash trees across 15 States. It has had a devastating effect wherever ash trees grow. Whether the ash is used by industry; shading homes and urban streets, or an integral part of our forest ecosystem, its decline due to EAB is being felt by everyone. Perhaps one of the hardest hit by this pest are Native American tribes of the Northeastern United States for whom brown ash is rooted deep in their culture, providing spiritual and economic support to their communities.

Life-giving Mother Earth is central in the lives of the tribes and ash trees in particular are highly treasured. The wood from ash is used to create snowshoes, hunting and fishing decoys, canoe paddles and medicinal remedies. Also, brown ash (also called black ash) in particular is used to create intricate woven baskets, toys and musical instruments. This invasive pest that so directly threatens the life style and tradition of many Native American tribes has also created an opportunity for collaboration and intellectual exchange between tribal groups and the USDA.

“Ash trees are important to Native people of the northeast, animals of the forest, and even the ecologies of the forest,” said Kelly Church, fifth-generation basket weaver, Grand Traverse band of the Ottawa and Ojibwe. “Each Federal agency, State agency, Tribal government, tribal harvester, or just one person can make a difference; but working together we can make a bigger difference for all of us.”

Many tribes have engaged their own communities to prevent the spread of EAB, in conjunction with supporting USDA EAB program efforts. The Cherokee, Mohawk, Ojibwe, Penobscot and other tribes survey for the pest, using purple panel traps, on lands they steward. Tribes also distribute EAB informational material to tourists and engage in one-on-one conversations to help educate campers about the risk of moving firewood. In addition, a group of Native American basketweavers are lending their knowledge and expertise to support EAB research. Scientists with U.S Department of Agriculture’s Center for Plant Health Science and Technology (CPHST) are investigating treatments to kill EAB in black ash logs so the raw material can be transported out of quarantine areas without spreading EAB. Tribes from Maine, New York and Michigan have stepped up to help evaluate the integrity of ash splints freshly pounded from black ash logs submerged in water for 4-months, a potential treatment. It was found that these splints were still viable as basket making material but unfortunately EAB larva also survived to complete its lifecycle. These trials continue.

With the future of the ash tree species in peril and long-held traditions in jeopardy, Native Americans have ignited their communities to help preserve their cultural heritage by collecting ash seeds. Working independently and in conjunction with the National Center for Genetic Resource Preservation, seed collection and storage will help to hedge genetic diversity of ash trees for future generations...

Water chestnut may be spreading in southeastern Pennsylvania


By Carolyn Beeler, www.newsworks.org

An invasive species of water plant seems to be spreading in southeastern Pennsylvania.

Water chestnuts--no relation to the ones in your Chinese food--have dense surface foliage that can crowd out other plants and threaten fish life. Their spiky seed pods that wash up on shore can make getting near the water painful for anglers and swimmers.

Conservation workers are waging war on them in Bradford Reservoir, also known as Warrington Lake, in central Bucks County. It's one of the first places in Pennsylvania where they were identified.

"The surface of the water is 100 percent covered with these plant rosettes, and they become very thick and matted," said Gretchen Schatschneider, district manager with the Bucks County Conservation District. "If you fly overhead, you almost don't see the lake, it just looks like an extension of the lawn area"...

Fred Lubnow, director of the aquatics program with Princeton Hydro, an environmental and engineering consulting firm, said the water chestnut has become a primary concern in the past few years.

"In the last I'd say two to three years we've really seen it appear in a lot of places on either side of the Delaware River," Lubnow said.

Emerald Ash Borer Detected In Buffalo, New York

Collaborative Control Efforts Underway to Contain First Infestation Found in Erie County

The New York State Department of Environmental Conservation (DEC) today announced an infestation of Emerald Ash Borer (EAB) was found in the City of Buffalo's South Park. This is the first EAB infestation to be detected in Erie County. EAB is a small but destructive beetle that infests and kills North American ash tree species, including green, white, black and blue ash.

"The discovery of the Emerald Ash Borer in Buffalo is extremely unfortunate but not surprising," DEC Commissioner Joe Martens said. "Despite multi-state efforts to curtail its expansion, EAB has spread across the northeastern United States over the last decade. DEC is coordinating with federal and local government partners across the state to prevent the further spread of this destructive insect, especially outside of the quarantine areas. Awareness and preparedness are our best defenses, both of which are emphasized in DEC's strategic Slow Ash Mortality (SLAM) program."

...

"Emerald Ash Borer is a serious threat to the region and the City of Buffalo has been preparing for its arrival for some time," said Deputy Commissioner Andrew Rabb of the City of Buffalo's Department of Public Works, Parks and Streets. "An effort to reduce the number of ash on city property was put in place after the first outbreaks occurred in Michigan. Ash now makes up less than 2% of Buffalo's street tree population and roughly 10% of trees in city parks. The city is working closely with the Buffalo Olmsted Parks Conservancy to develop and implement a treatment plan for historic landscape trees."

Buffalo Olmsted Parks Executive Director Thomas Herrera-Mishler said, "We have been partnering with the City of Buffalo and DEC for over a year to prepare for this outbreak, raising funds and public awareness to try to minimize the impact of EAB on the historic Olmsted Parks and Parkways."

DEC, Cornell University, the City of Buffalo and Buffalo Olmsted Parks Conservancy began collaborative response efforts to address the infestation at South Park immediately after the discovery last week. Initial surveying suggests that less than a dozen trees in South Park show signs of infestation; the trees are located along the park's perimeter in a natural wooded area.

...

EAB was first detected in New York State in Cattaraugus County in 2009. Since then, infestations have been confirmed in seven other counties including Genesee, Monroe, Livingston, Steuben, Greene, Ulster and now Erie. Sixteen counties in western New York and Greene and Ulster counties remain quarantined...

PA looking for more ways to pay for wildlife services


Saying hunters, anglers pay their share, state agencies seek new money to manage wildlife

Sunday, January 17, 2010
By John Hayes, Pittsburgh Post-Gazette

Some people look out the window and see a natural world that could take care of itself if we would just leave it alone.

But those more experienced in the outdoors and employees of the two agencies that manage the state's wildlife see something else: A man-made landscape of unnatural second growth teeming with thousands of species of plants and animals living in a constantly changing artificial environment.

In short, they see the need for constant and costly stewardship of Pennsylvania's wildlife resources. But it's become increasingly hard to pay for it.

Officials at the state's separate Game Commission and Fish and Boat Commission said they're struggling to find alternative funding necessary to maintain services. With a deficit expected in 2011, Fish and Boat commissioners are considering raising fees for fishing licenses.

Unlike other state agencies, the wildlife management commissions get no money from Pennsylvania's general fund, relying since their founding about 100 years ago on revenue raised from hunters and anglers. With no contribution from the general public and a new emphasis on maintaining habitats for nongame species, agency officials said they're strained to the breaking point.

A 2006 U.S. Fish and Wildlife Survey found that while participation in traditional hunting and fishing was waning, wildlife watching had become the fastest growing outdoors pastime, both nationally and in Pennsylvania.

But plans for expanding the state agencies' existing management of nongame species -- including goals detailed in the Game Commission's newly released five-year plan -- are not financially sustainable under the state's current funding process.

"Wildlife watchers are not funding what they're doing directly," said Jim Bonner, executive director of the Audubon Society of Western Pennsylvania. "And some of them don't even know it."

Doug Austin, executive director of the Fish and Boat Commission, said even many hunters and anglers don't know where their license fees are going.

"The general public is relatively naive about how the whole system works," he said.

"There's a large percentage of people who don't realize what the Game Commission and Fish and Boat Commission actually do," Mr. Bonner said, "or that they're funded almost entirely by license fees from hunters and fishermen and the use of state game lands. ... They're in a tough position."

Game Commission executive director Carl Roe is more succinct: "Eight percent of the population is paying for wildlife that is enjoyed by 100 percent of the population."

Invasive politics: Restricting bass boats won't solve plant problem

By Wayne Hooper
January 17, 2010 2:00 AM

Invasive plants are a concern for fisherman, camp owners and fish and game departments of all states.

Some camp owners blame the rise in the number of plants on the boaters, which is wrong. The fish and game departments haven't a clue what to do and the fishermen and boaters are fighting for their rights to zoom up and down the lakes.

Let's break this down. There is a legislative document in the Maine House that will be discussed in the next week or so that states, "No bass tournaments shall be held on any body of water that has invasive plants in it." One legislator has taken upon herself to try and stop bass boats from fishing the lakes as she thinks they are the problem.

My letter to her stated that this is discriminatory, as it blames one group of boaters as the culprits. In it, I said, "If you outlaw all boats at least you would stand a better chance of getting this passed, albeit a slim chance, as whomever votes for a bill such as this will most likely not get reelected in any northeast state. In fact, stoning, tar and feathers, a tea party and so many other reprisals come to mind. In other words, your political career would be hanging by the thinnest of fishing line."

I asked her if she had a camp on a lake that held bass tournaments or did she have a friend who did and she told me she had a cottage on Salmon-McGrath Lake, a bass tournament lake. I asked her why she blamed bass boaters and she really didn't have an answer. She stated that we need to fix this situation. I explained to her that these plants started 40 years ago in Florida, so anyone who fishes bass tournaments is educated, plus if you ask any of the volunteer inspectors at the ramps throughout the state they will tell you how clean bass fishermen keep their boats. They do not want to spread these plants, as it affects the fishing and bass fishermen are all about keeping fish alive, working on conservation projects and helping to pass laws to protect the black bass.

However, if you really think or have been told that bass boats carry plants from lake to lake, that is an absolute LIE. Can this happen? Sure, but every bass club has an invasive plant inspector whose job it is to check all the boats at every tournament. Also, bass boats are usually fished on Sundays and then sit in the yard until the next weekend. By that time the plants would dry out and die. However, if we did transport invasive plants, why aren't there any at the ramps? The ramp areas are clean of weeds and plants. [...]

UVM researcher rethinking the benefits of worms

By Cheryl Dorschner, Special to the Burlington Free Press • Saturday, January 16, 2010

Nevermind that more than three feet of snow cover many Vermont gardens right now.

Nevermind that this January and February are "gardeners' holidays." Oh, gardeners bundle up and travel the country to dazzling flower shows. They peruse bright catalogs and Web pages weighing the price of $7 packets with barely a dozen seeds inside vs. owning and growing the next new thing. And they dream.

But Vermont gardeners do not give a whit about worms right now.

They should -- because under all that snow and topsoil, the rules have changed.

Ask a gardener about earthworms, and they're extolled as the architects of the underground. Tunneling to aerate and drain soil and bring subsoil to the surface, they chomp through detritus, turn it into rich humus and leave behind castings valued for their high fertility. Earthworms were the darlings of Darwin and are the Vita-Mix of vermiculturists.

Now a University of Vermont research scientist is turning traditional thinking on its ear. Josef Gorres, a plant and soil science faculty member, teases out the truth about life in the universe that lies between sky and bedrock -- topsoil, leaf litter and earth's teeming surface. His findings demonstrate even more so than we already know -- that a sustainable ecosystem is one of delicate balance, of species indicators that signal the overall health of the soil and of the communities of small animals that may turn out to be linchpins of the food web.

New angle on worms

Gorres is seeing firsthand that where worms congregate in the forest, "There is no leaf litter, no organic layer and not as much pore space," he says. As a result, "the surface seed bank is exposed to seed predators and harsh weather. This is where small plants germinate, but because the duff is gone, they can't do that. Therefore, there are fewer herbaceous plants."

Besides grinding the woodland carpet and exposing seeds, earthworms leave a different soil -- fertile in nitrogen, phosphate and potassium.

"Native plants may not adapt to the fast release of nutrients that earthworms cause," Gorres says. "And one hypothesis is that exotic invasive plants move in instead because they have fewer competitors, bare ground to colonize and maybe the edge over natives that are slower to become active earlier in the spring."

Worms' effects on wildflowers and shrubs are documented, but Gorres is interested in the long-term change of the forest canopy. "I'm also interested in how earthworms change the chemistry of soil in production maple forests because that could change the flavor of maple syrup and the color of the foliage," he says. "That part is speculative, but no one has looked at that."

Laying bare the forest floor is fairly new in the Northeast's natural history. Colonists brought Lumbricus terrestris to the Americas on rootstocks and in ship ballast; over time these all but replaced native earthworm populations and spread to wormless areas. Gorres estimates about 15-20 invasive earthworm species in the Northeast. Normally populations spread slowly; nowadays, worms are introduced by construction, with plants, when gardeners purchase red wigglers and by fishermen who dump bait.

While people are well aware of devastating invasive forest insects such as emerald ash borer and hemlock wooly adelgid heading toward Vermont, here's a surprise: "A relatively new worm called 'crazy snakeworm' was first discovered in the 1990s in nine commercial greenhouses in New York City. It is many times more voracious than other earthworms," Gorres says.

He's identified one as well -- in 2008 -- in a patch of ferns at the woodland edge of UVM's own Horticultural Research Farm in South Burlington.

"I'm aware of the two schools of thought, worms as beneficials or invasives, but it would appear to pit gardeners against those concerned with forest ecology," says Alice Beisiegel, who gardens and operates Leaves of Grass landscape design business from Williston. "I do know that my woods are full of earthworms and trilliums, uvularia and other plants that earthworms supposedly harm."

Indeed, all gardeners treasure both the cultivated and uncultivated land, so dearly that these findings -- wait for it -- open a can of worms.

The Vexing Bugs in the Global Trading System


As More Goods Are Imported From Overseas, Greater Numbers of Invasive Insects and Plants Also Arrive and Bite Business

By KRIS MAHER, The Wall Street Journal

FAYETTEVILLE, West Va.—Perched on a platform 50 feet above the ground in a big hemlock named Fern, Geoff Elliott points to an unwelcome Asian import: a little bug known as the hemlock woolly adelgid.

Small fuzzy white nymphs cling to the undersides of hemlock branches throughout the grove of trees. Both nymphs and adult adelgids can work quickly to destroy hemlocks 150 feet tall.

"This tree is believed to be somewhere between 200 and 300 years in age and can be taken out by the adelgid in as little as two to four years," says Mr. Elliott, a tour guide for Adventure West Virginia Resort LLC, which operates zip-line tours through the treetops. The company is trying to educate visitors about the dangers of the invasive insect as it diminishes the landscape the business relies on.

"Without any action we could lose the species," said Mark Whitmore, a forest entomologist at Cornell University. He described the hemlock as a "keystone species," because it provides shade that cools streams so fish can survive as well shelter for birds and animals. Losing it would be like "having all your front teeth fall out," he said.

As global trade has mounted, more goods are coming in from overseas, sometimes bringing with them the accidental cargo of destructive bugs and plants. An estimated 500 million plants are imported to the U.S. each year, and shipments through one plant inspection station doubled to 52,540 between 2004 and 2006, according to the U.S. Department of Agriculture. Today, about 30 new invasive insects are discovered annually in the U.S., up sharply over the last decade, the USDA says.

The yearly economic impact of invasive species in the U.S. is estimated at $133.6 billion, according to a study in Agricultural and Resource Economics Review in 2006. That includes the cost of control and prevention such as pesticides, inspection programs at ports and damage to crops.

An estimated 50,000 plant, animal and insect species have been introduced into the U.S. throughout history. Many plants are initially introduced as food or ornamentals, while animals are occasionally introduced to control other pests. The English sparrow was brought over to control the canker worm on crops in 1853. But by 1900, it was considered a pest because it introduced diseases.

Among the most damaging are weeds that affect crops or destroy animal habitats. The Asian purple loosestrife, for example, was introduced as an ornamental plant in the early 19th century and now invades some 284,000 acres per year in the U.S., crowding out native plant species that help support duck, geese and muskrat.

More recently, invasive species can be directly traced to increased trade. The Asian longhorned beetle hitched a ride on shipping pallets to Brooklyn, N.Y. from China, while others like the zebra mussel have arrived in the Great Lakes in the ballast water of ships from Europe, having spread there from Russia.

Once invasive species take hold in regions where they have no natural predators, it is often impossible to eradicate them. The emerald ash borer, a shiny green beetle from Asia believed to have arrived on packing material, is attacking ash trees. In the northeast, the Asian longhorned beetle has killed thousands of maple trees and other species. [...]

Invasive Species Multiply in U.S. Waterways

By Matthew Berger
Inter Press Service News Agency

WASHINGTON, Jan 4, 2010 (IPS) - As 2010, the U.N.'s International Year of Biodiversity, gets underway, a fight against some of the most damaging invasive species in U.S. waterways is heating up.

The U.N. says some experts put the rate at which species are disappearing at 1,000 times the natural rate, and invasive species – which consume the food or habitat of native species, or the native species themselves – are one factor contributing to this acceleration. Climate change is another major factor.

"Often it will be the combination of climate change and [invasive] pests operating together that will wipe species out," says Tim Low of the Australia-based Invasive Species Council.

The International Union for Conservation of Nature says that 38 percent of the 44,838 species catalogued on its Red List are "threatened with extinction" – and at least 40 percent of all animal extinctions for which the cause is known are the result of invasive species.

But just as invasives are not the only threat to biodiversity, the threat to biodiversity is not the only problem caused by the havoc – ecological as well as economic – wreaked by species that are transported to a foreign habitat, get a foothold there and spread, often voraciously.

The U.N. Convention on Biological Diversity says the spread of invasives costs 1.4 trillion dollars a year globally in damages and control measures. The U.S. alone loses 138 billion dollars a year in the fight.

The problem can be seen throughout U.S. waterways, from Asian clams in California's Lake Tahoe to snakehead fish in the East Coast's Potomac River. One of the most immediate threats – Asian carp – is currently on the doorstep of the Great Lakes ecosystem, where it could decimate a seven-billion-dollar fishing industry among other economic and ecological assets.

After being imported to the southeastern U.S. in the 1970s for use in containing aquatic plants, bighead and silver carp, collectively referred to as Asian carp, eventually escaped from fish farms there and made their way north via the Mississippi River. They have taken over stretches of adjoining waterways such as the Illinois River and evidence was found in November that the fish are within seven miles of Lake Michigan.

The concerns over what a carp infestation might mean for the Great Lakes' industries and environment are several-fold. Asian carp are voracious eaters, consuming 40 times their body weight in a day, and females can carry a million eggs and spawn multiple times in a season.

Silver carp, which can top out at 1.2 metres and 45 kilogrammes, jump far out of the water at the sound of a boat motor. They are generally unappealing to U.S. consumers as food fish due to the floating bones in their flesh.

The battle over how to protect the Great Lakes ecosystem – which accounts for 20 percent of the world's freshwater – has now made it to the U.S. Supreme Court, where Michigan and other Great Lakes states are suing the state of Illinois to temporarily shut canals in the Chicago area that connect the Mississippi River system to Lake Michigan, thus blocking the fish's path until a tenable solution is agreed.

The lakes have been hit before. Zebra mussels, for instance, have colonised the region's waters beginning in the late 1980s. Zebra and quagga mussels, both of which were most likely transported to the U.S. in the ballast water of trans-oceanic ships, have since spread across the country, clogging pipelines and water intakes at significant economic cost. [...]

The Role of Climate Change

Local species may become even more vulnerable to certain invaders as the effects of climate change are increasingly felt and habitats are disrupted by phenomena such as warmer temperatures and rising sea levels.

"We know invasive species can capitalise on these disturbances," says Scott Loarie, a co-author of a study in the current issue of the journal Nature which points out how fast species will have to migrate to keep pace with a changing climate. As ecosystems are transformed, "weedy-type species might be able to adapt and expand better than the original species," he says. [...]

A changing climate is likely to hit aquatic species quickest. A recent study by researchers at NASA's Jet Propulsion Laboratory found that lake surface temperatures in six Northern California and Nevada lakes are, on average, warming at twice the rate of the surrounding air.

One potential fallout of this trend is a more hospitable environment for invasive species, like the Asian clam that first appeared in California's Lake Tahoe at the beginning of this century but which is now prevalent enough that its waste has caused algae blooms in the lake's tourist-drawing crystal waters. [...]

Though climate change is only one factor in the spread of invasives, these intruders are generally given a leg up by the disruptions caused by a changing climate since they are typically very hardy species and adept at capitalising on opportunities to colonise areas. [...]

Lake Superior Aquatic Invasive Species Complete Prevention Plan


The Draft Lake Superior Aquatic Invasive Species Complete Prevention Plan Request for Comments


We are soliciting comments on the draft Lake Superior Aquatic Invasive Species Complete Prevention Plan, by February 26, 2010.

The Lake Superior Binational Program recognizes that aquatic invasive species are one of the biggest threats to Lake Superior in terms of negative ecological and economic impacts. To address this critical threat, the Lake Superior Binational Program developed a draft Aquatic Invasive Species Complete Prevention Plan (Plan) for the lake. The Plan identifies the pathways aquatic invasive species use to enter and become established in the lake. Further, the Plan recommends prevention actions that need to be newly implemented, in addition to existing efforts, in order to close existing pathways on both sides of the border and prevent new aquatic invasive species from entering the Lake Superior ecosystem. The draft plan is available at: Lake Superior Aquatic Invasive Species Complete Prevention Plan (draft) [PDF 800 Kb 81 pages].

A series of conference calls will be scheduled for February 2010. On these calls, the plan will be presented via a webcast, and comments will be welcome. In addition, a series of workshops will be held in the spring and summer of 2010 to provide additional information and answer questions. Additional workshop details will be available in early 2010.

After the comment period closes on February 26, 2010, we will consider all comments, revise the Plan accordingly, and finalize.

You may submit any comments on the AIS Complete Prevention Plan by February 26, 2010 here.

Asian Carp Will Soon Invade Store Shelves

by The Associated Press

Building off a state-developed marketing plan, a group of Louisiana-based companies has started a joint venture that will put Asian carp on retail shelves within weeks.

The fish are being marketed as silverfin, the name it was given in a marketing plan developed by the Louisiana Department of Wildlife and Fisheries. The agency is promoting recreational and commercial applications of an invasive fish that has caused huge problems for boaters in northern states.

Rather than poisoning the fish to get rid of them like northern states have done, wildlife officials are opting to make them an appetizing meal.

Chef Philippe Parola of Baton Rouge, CEO of Chef Parola Enterprises and Partran, kick-started the campaign in the fall, and it's finally coming together in the New Year. [...]

crabMitten crabs are invading UK rivers and may be commercially harvested to control numbers reports the Independent (UK). This foreign species of crustacean is native to China where it is highly prized as a delicacy, especially the roe of the mitten crab. Diners in China, Japan and Singapore will pay the equivalent of £24 [about $39 USD] for a mitten crab in good condition.

In the UK, this aggressive species has spread up the Thames and is now populating other rivers and waterways where it causes damage to the banks and the natural ecosystem. “It is a huge pest problem,” says Paul Clark, a marine biologist at the Natural History Museum. “It burrows into river banks and causes them to collapse, and is very damaging to native wildlife.” Mitten crabs in the Thames are now reaching such numbers that they may block water intake pipes of power stations and other industrial facilities.

Dr Clark has suggested that the solution to the problem may be simpler than first thought – eat them. He is proposing a conference in London in March to explore the possibility of commercially harvesting the crabs from the Thames. A recent study found that the crabs are fit for human consumption and are found in such numbers that exploitation would be viable.

“Mitten crabs have few natural enemies capable of reducing their numbers, but the establishment of a fishery would certainly carry risks.” Said Dr Clark.

Asian carp plea denied

Lyle Denniston | Tuesday, January 19th, 2010 10:10 am
SCOTUSblog
www.scotusblog.com

The Supreme Court refused on Tuesday to order emergency measures sought by the state of Michigan to stop the migration of an invasive fish species, Asian carp, toward Lake Michigan from rivers and a sanitary canal in Illinois. Without comment, the Court refused to issue a permanent injunction that would have closed waterway locks and required other temporary measures in reaction to the discovery of the carp upstream in Illinois rivers. The Court’s order did not dispose of Michigan’s plea to reopen a decades-old decree to address the carp migration issue on its merits. That will come later in cases 1, 2 and 3 Original, Wisconsin, Michigan and New York v. Illinois.

NJ Conservation Foundation Applauds New Forest Stewardship Law

By New Jersey Conservation Foundation

New Jersey Conservation Foundation applauds the state Legislature and former Gov. Jon Corzine for passing a landmark bill that provides incentives for private landowners to improve the health of New Jersey forests.

The Forest Stewardship Act was passed by the Senate and Assembly on Jan. 11 and signed into law by Gov. Corzine during his last full day in office, Monday, Jan. 18.

The new law allows landowners with at least five acres to be eligible for reduced property tax assessments by actively managing their woodlands to promote forest health and sustainability.

Previously, the same woodland owners participating in the farmland assessment program were subject to an income requirement, which forced landowners to cut their trees for timber and firewood. The practice was not sustainable and resulted in a major loss of forest productivity and biodiversity. [...]

Stewardship activities can include: removing invasive plants, restoring endangered species habitat, fencing property to encourage regeneration and prevent deer damage, and resolving problems caused by erosion, disease and pests.

The new law directs the state Department of Environmental Protection (DEP) to establish a forest stewardship program for owners of forested land who prepare stewardship plans for five acres of land or more. Under the bill, plans would be required to meet the rules and regulations of sustainability, list the owner’s long term stewardship goals for the forest land and the annual activities that will be implemented in the forest.

The law also directs the DEP to:

* Establish a cost share incentive program, "New Jersey Forest Stewardship Incentive Program," if funds are appropriated or otherwise made available for the support and funding of such a program, the DEP would award grants to local government units, non-profit organizations, and private owners of forest land to help subsidize their costs in implementing stewardship activities.
* Create a forest stewardship advisory council
* Prepare a report every seven years based on these forest sustainability criteria and indicators, with the first report required by February 1st of the third year following the date of enactment.

Special thanks are due to the bill sponsors: Senators Bob Smith, Jeff Van Drew, John Adler, Robert Gordon, Andrew Ciesla, Christopher "Kip" Bateman and Robert Singer and Assemblyman John McKeon. For more information on the Forest Stewardship Bill, contact New Jersey Conservation Foundation at info@njconservation.org or 1-888-LAND-SAVE (1-888-526-3728).

New Jersey Conservation Foundation preserves land and natural resources throughout New Jersey for the benefit of all. Since 1960, the Foundation has protected more than 120,000 acres and has been an advocate for strong land use policies. For more information, visit www.njconservation.org

Carp DNA Is Found in Lake Michigan

By SUSAN SAULNY
New York Times
Published: January 19, 2010

CHICAGO — Genetic material from the Asian carp, a voracious invasive species long feared to be nearing the Great Lakes, has been identified for the first time at a harbor within Lake Michigan, near the Illinois-Indiana border, ecologists and federal officials said Tuesday.

A second DNA match was found in a river in Illinois within a half-mile of the lake, according to scientists at the University of Notre Dame who tested water samples and provided the results to officials last week.

Experts said the most recent findings, from Calumet Harbor and the Calumet River, could mean that the carp has found its way beyond an elaborate barrier system built at the cost of millions of dollars to prevent the fish’s access to the Great Lakes and its delicate ecosystem, where it has no natural competitors and would threaten the life of native fish populations.

“It’s a big admission of failure,” said Henry Henderson, the director of the Midwest program at the Natural Resources Defense Council. “It indicates the kind of thing we’ve been fearing since 1993.”

Government officials were careful to underscore that they had not found any fish — dead or alive — despite much effort, and that the Asian carp’s DNA could have arrived in Lake Michigan by various means other than the fish’s swimming from river basins it has already overtaken farther south.

Salazar Moves to Ban Importation and Interstate Transfer of Burmese Python and Eight Other Giant Invasive Snakes

FWS to Propose Injurious Species Listing under Lacey Act

NEW YORK, NY – Secretary of the Interior Ken Salazar today announced the U.S. Fish and Wildlife Service will propose to list the Burmese python and eight other large constrictor snakes that threaten the Everglades and other sensitive ecosystems as “injurious wildlife” under the Lacey Act.

Salazar made the announcement at the Port of New York, which serves as the largest point of entry in the nation for imports of wildlife and wildlife products. Last year, U.S. Fish and Wildlife Service Inspectors at John F. Kennedy International Airport handled more than 27, 000 separate wildlife shipments valued at more than $1 billion, or 16 percent of all U.S. wildlife imports.

The proposal, which will be open to public comment before Salazar makes a final decision, would prohibit importation and interstate transportation of the animals.

“The Burmese python and these other alien snakes are destroying some of our nation’s most treasured – and most fragile – ecosystems,” Salazar said. “The Interior Department and states such as Florida are taking swift and common sense action to control and eliminate the populations of these snakes, but it is an uphill battle in ecosystems where they have no natural predators. If we are going to succeed, we must shut down the importation of the snakes and end the interstate commerce and transportation of them.”

In total, wildlife inspectors stationed at ports across the nation processed more than 169,700 shipments of wildlife and wildlife products last year with an estimated value of $2.7 billion.

“Our wildlife inspectors are the front line of defense for the nation, combating illegal wildlife trafficking and preventing the importation of countless species of illegal injurious wildlife. This proposal will give them an additional tool to restrict imports that are causing significant ecological and economic damage, while giving our law enforcement agents the ability to restrict the spread of these species within our borders,” said U.S. Fish and Wildlife Service Director Sam Hamilton.

The nine species proposed for listing are: the Burmese python, northern African python, southern African python, reticulated python, green anaconda, yellow anaconda, Beni or Bolivian anaconda, DeSchauensee’s anaconda, and boa constrictor. [...]

Coconut palms bring ecological change to tropics, Stanford researchers say

Those graceful coconut palms swaying in tropical breezes are lowering nutrient levels in the soils and the plants around them, thereby altering the eating habits of animals. Researchers say it’s one example of how a change in a plant community can disrupt an entire ecosystem.

BY LOUIS BERGERON
Stanford Report, January 20, 2010

Coconut palms, the epitome of South Seas tranquility, turn out to be doing more than just soothing vacationers and inspiring aloha shirts. As they continue to spread to new areas, they are also changing the very landscapes they grace, according to Stanford researchers. Seabirds are shunning the palms as nesting sites, favoring other tree species instead, sending a ripple through island ecosystems.

With the birds has gone the rich cargo of guano that they normally dispense so freely to the earth under their abodes. The absence of that precious input has caused the soil around the palms to become nutritionally deficient.

That, in turn, is lowering the nutritional content of plant species growing around the palms and is causing the creatures that feed on those plants, such as crabs and grasshoppers, to forage elsewhere.

"We found that you can get a five- to twelvefold decline in important soil nutrients such as nitrate and phosphate when coconut palms are present, mainly because the birds aren't there depositing nutrients to that system," said Hillary Young, a doctoral candidate in biology and member of the research team that conducted a study on Palmyra Atoll in the South Pacific. Palmyra lies roughly midway between Hawaii and Tahiti. [...]

Just how long the palms have been growing on Palmyra, or how they arrived, isn't clear. Most researchers agree that coconut palms originated in Asia. Coconuts can travel long distances by floating on the ocean currents, but the palm was probably introduced in much of its current range, including areas like Hawaii and the Americas, by early human travelers a few thousand years ago.

Updates on ALB, EAB & Sirex Woodwasp

APHIS scientists have studied survival of emerald ash borer (EAB) larvae in firewood that has been heat treated. The conclusion: EAB larvae and prepupae survive HT at various temperatures and time intervals. A minimal safe treatment for firewood would require internal wood temperature of 60 degrees C for 60 minutes. The current requirement for firewood is internal temperature of 71 degrees C for 75 minutes. The article does not discuss the implications of this finding for imports of wood packaging, which (per ISPM#15) must be heated only to 56 degrees C for 30 minutes. (I have the full article if you wish to see it.)

USFS scientists are testing a trap for Asian longhorned beetle (ALB) that uses a lure comprised of chemicals emitted by male beetles and volatiles emitted by host plants. Initial tests were carried out in China; last summer the traps were tested at the large ALB infestation in Worcester, MA. The MA traps caught 9 females – compared to 29 adult ALB found by surveyors or residents. The catches in Dodge Park steered officials to 2 trees previously not known to be infested. Further surveys of trees near the traps are under way to assess the traps’ efficacy. Good news! Not that long ago, scientists thought Cerambycids did not communicate by chemicals – which made developing monitoring tools very difficult.

APHIS still has not developed a regulatory program to slow spread of the Sirex woodwasp from its current locations (NY, northern PA, corners of MI, OH, & VT; and Ontario) to the pine-rich woodlands of the Southeast and West. One reason is stakeholders’ failure – so far – to persuade Congress to provide adequate funding. If managers of pine forests and plantations are counting on the nematode which has been used as a biocontrol agent in plantations in the Southern Hemisphere (nematode Beddingia (=Deladenus) siricidicola). At a recent meeting, several scientists from the southern hemisphere described the complexities of trying to manage the nematode and get good rates of infestation of the woodwasp. Complexities include:

• Biocontrol program must be coordinated with active silvicultural management of the pine stands – failing to thin at proper time increases vulnerability.

• Mortality of trees used to introduce the nematode into the system - due to drought or attacks by other insects - undermines efforts to deploy biocontrol nematode and can reduce infection rate to ineffective levels.

• Difficulties of detecting leading edge of infestation – aerial surveys don’t pick up fast enough.

• Care needed in raising nematodes – must have proper strain of nematode, proper strain of fungus on which being raised.

• Care needed in techniques for inoculation of trees.

• Competition from bluestain fungi (quite common in North America) might suppress the Amylosterium fungus on which both the nematodes and the wasps feed.

• Might need to use different fungal strains depending on whether your pine stand is in a summer v. winter rainfall area.

• Strong/large woodwasps (that have not been infected by the nematode) still fly significant distance from “birth” tree – in Patagonia, the nematode has not slowed spread of the woodwasp.

• Contrary to previous understanding, North American native woodwasps and the introduced Sirex noctillio do not always utilize different species of Amylosterium fungi – so that cannot be relied upon to ensure that the introduced nematode does no harm to native woodwasp populations.

More than $1 Million for projects to improve the health of Long Island Sound

Funds awarded to control perennial pepperweed


pepperweed(Waterford, Conn. – Oct. 29, 2009) – Gathering together on the shores of Long Island Sound, top federal and state environmental officials announced 33 grants to state and local government and community groups under the Long Island Sound Futures Fund. The $1,011,878 will be leveraged by $1.92 million contributed by the recipients, providing a total of nearly $2.94 million for on-the-ground conservation in Connecticut and New York. [...]

This year’s grant program funded 21 large grants (grants greater than $10,000) totaling $943,755. Five grants were awarded for water quality; four for habitat restoration; one for watershed planning; one for invasive species control; seven for education; and three for stewardship projects. [...]

The grants include $38,538 to control perennial pepperweed (Lepidium latifolium) at West Meadow Beach, Town of Brookhaven, New York. EEA Inc. assisted the Town of Brookhaven with their grant application and perennial pepperweed control plan.

EEA scientists discover perennial pepperweed in 2006

EEA scientist Denise Harrington discovered New York State's only known infestation of perennial pepperweed at West Meadow Beach in 2006. Numerous plants were found occupying the upper edge of the salt shrub zone, immediately landward of marsh elder. This year, Kathy Schwager of The Nature Conservancy and EEA scientist Bill Jacobs returned to the site to map the plant's current extent. The infestation appears to be spreading.

Perennial pepperweed poses a serious threat to native maritime ecosystems by creating large, dense, monospecific stands that displace native plants. Infestations at West Meadow Beach are scattered, covering a total area of approximately one acre in size.

Invasives still a major concern in Great Lakes

By Chuck Quirmbach, Wisconsin Public Radio

zebra_musselsMILWAUKEE (WPR) Even with new clean-up money on the way, scientists continue to worry about invasive species in the Great Lakes.

Congress has agreed to spend $475-million on a Great Lakes restoration plan over the next year. But some worry the money won't be as effective as it could be without tougher federal controls on ballast water discharges from ships in the Great Lakes. Contaminated ballast is believed to be a key source of invasive species in the waters.

This week, an Obama administration panel held a hearing to look at new policies for the Great Lakes and the Pacific and Atlantic oceans. University of Notre Dame biologist David Lodge described some of harm invasives are causing for great lakes whitefish, who have become increasingly skinny and not as valuable to commercial fisheries.

The federal task force is supposed to make specific policy recommendations within a few months. Those could influence how some of the new money is spent.

Help the Great Lakes

President's boost in budget proposal should be backed fully by Congress


The Buffalo News: Opinion

Having a Chicago politician as president of the United States — and another as his chief of staff — has some scary implications that should never be completely ignored.

But one good thing about a White House with connections on The Loop is that there is likely to be a healthy amount of concern for the Great Lakes.

That concern was reflected in President Obama's budget proposal, which included a helpful $475 million for projects to clean up the five lakes that provide drinking water, transportation routes, recreational opportunities and so much other support for the economic and environmental spheres that include Buffalo.

The lakes and their tributaries are so large, and so seldom catch fire any more, that the problems can be hard for non-experts to see. But problems there are — as well as opportunities.

The lakes are polluted, and becoming more so every day. Invasive species, brought in by ocean-going vessels that are key to the regional economy, are becoming an ever-greater problem. Bordering wetlands are also polluted and gummed up in many ways. That's no way to treat the source of one-fifth of the planet's surface fresh water supply, water source for 35 million people, and the reason why cities from Rochester to Toronto to Detroit to Chicago to Milwaukee were founded in the first place.

The president's budget proposals will go a long way to address all those problems. They will help municipal sewage treatment facilities and other sources of pollution clean up their acts, restore damaged wildlife habitats and restore more of the lakes' bays, coves and shores to the kind of ecosystem that can sustain wildlife and human habitation.

And, in the bargain, the money will provide productive employment for many people at a time when such opportunities are in short supply.

In the long process of reviewing the budget, the Senate went along with Obama's full $475 million request. The House cut it to $400 million. The difference will be resolved on conference committee and then voted on again by both bodies.

The lesser amount would be an improvement over past years' funding. But the whole request would do a lot more, for projects that have been too long delayed already, employing people who will have something very great indeed to show for their work. Congressional delegations from the Great Lakes state should take note — and get to work.

President signs legislation to benefit Great Lakes

By Ducks Unlimited

ANN ARBOR, Mich. – November 2, 2009 –President Obama signed historic legislation aimed at the restoring the Great Lakes, Friday, after the House and Senate approved the measure. According to Ducks Unlimited, the Great Lakes Restoration Initiative will provide $475 million for a comprehensive program to restore and protect the Great Lakes. Ducks Unlimited stands ready to turn this financial commitment into cleaner water and better habitat for waterfowl, wildlife and citizens of the Great Lakes and beyond.

“Congress and the President have delivered on their promise to help protect and restore one of our national treasures,’ said Robert D. Hoffman, Director of Ducks Unlimited’s Great Lakes/Atlantic Region. “We are grateful to all of the Great Lakes partners and Congressional and Administration champions for making this funding a reality.”

The Great Lakes Restoration Initiative (GLRI) was proposed by the President to address the most serious issues that face the Great Lakes. Loss of habitat, invasive species, nonpoint source pollution, and toxic sediments threaten the health and economic well being of residents and damages the United States largest fresh water resource. Program administrators have a valuable document in the Great Lakes Regional Collaboration Strategy, a blueprint developed by more than 1,500 people representing governmental, industry, and nonprofit groups to set priorities and identify needs, which will receive funding for its most pressing programs.

Lake weeds the top topic at two Natick, MA meetings this week

By Charlie Breitrose/Daily News staff
The MetroWest Daily News
Posted Nov 02, 2009

NATICK, MA — The Board of Selectmen and the Conservation Commission this week will each discuss the ongoing negotiations about using herbicide to control weeds in Lake Cochituate, Massachusetts.

Selectmen tonight will hear from Carole Berkowitz, spokeswoman for Protect Our Water Resources. POWR opposes a plan by the Massachusetts Department of Conservation and Recreation (DCR) to use chemicals to fight milfoil, a non-native weed infesting parts of the lake. The meeting begins at 7 p.m. in Town Hall.

POWR and the Natick Conservation Commission have both appealed a state Department of Environmental Protection (DEP) decision allowing the DCR to use herbicide. In the decision, DEP officials stripped many conditions set by the Conservation Commission when it agreed to let the DCR use the herbicide diquat on five acres of the lake near the public beach and boat ramp.

The conditions removed from the commission's ruling included: monitoring the amount of the chemical in the lake water; posting warnings of the chemical use; and requiring the DCR to run a pilot project to study how well a diver-assisted suction harvester (DASH) boat removes the weeds.

A hearing is scheduled for Dec. 15, and Berkowitz said witness statements and reports for the hearing will soon be available.

Natick Conservation Agent Bob Bois said there is still a chance the hearing will not be needed. He and other town officials recently met with representatives from DCR to try to come to an agreement.

"There was a good discussion. We looked for common interests and we agreed to meet again," he said. "Our hope is we can reach a settlement between DCR and the Conservation Commission, which includes restoring the original order of conditions."

The lake weeds will also be the topic of discussion at the Conservation Commission's Wednesday night meeting, Bois said. Officials from the DCR will give an annual report on Lake Cochituate starting at 7:15 p.m. in Town Hall.

Bois said he hopes they will tell the commission about how well a DASH boat fared in a test run on Lake Cochituate during the spring.

"We're hoping it's one of the things DCR will talk about - the effectiveness of the DASH boat used in April," he said. "It would be nice to share that information with the board."

Berkowitz said POWR want to use a DASH boat to control the milfoil in the lake. She said she had a professional diver, who may be interested in bidding to run the DASH boat, come out to look at the lake last week.

The DCR used the boat to clear a channel in Snake Brook Cove, which lies between North and Middle ponds.

"The diver looked at it and it's good," Berkowitz said. "It was clean (of weeds). He was very impressed."

Other items likely to be covered by DCR officials are the harvesting of water chestnut plants in Fiske Pond, and the management of milfoil in Lake Cochituate's South and Middle ponds, Bois said.

New funding for milfoil in Maine

DASHSTANDISH, Maine (AP) — The Maine Milfoil Consortium, a group that addresses the threat of invasive aquatic plants in the state's lakes, has been awarded $500,000 in federal funds.

The money will be used to mitigate and control invasive milfoil in seven "test bed" lakes, which pose a high risk of spread to other waters.

The mission of the consortium is to address the milfoil infestation threat through a program of prevention, research, management, mitigation, and eradication through the application of "best practices."

The consortium says 26 Maine lakes are infested with variable-leaf milfoil, which disturbs the ecology of lakes vital to recreational boaters, homeowners and businesses.

Connecticut targets invasive plants




HARTFORD, Conn. - Connecticut authorities are hoping that new projects in four towns will help stop the spread of fast-growing invasive plants.

The state Department of Environmental Protection says the invasive plants threaten other plants and animals in the native ecosystems.

The biggest project is a $78,000 effort to fight the aggressive fanwort plant in the Bantam River system in Litchfield and Morris. If it's left to grow, it could harm Bantam Lake, which is Connecticut's largest natural lake.

Smaller projects are targeting the fast-growing "mile-a-minute" vine in New Milford and Newtown, and water chestnut plants that took hold in a Hartford flood control pond after getting into the Connecticut River.

Invasive Beetle Found in Juniata County, Pennsylvania

ABC27 News

EABHarrisburg, Pa. - A tree-destroying insect first discovered in Pennsylvania two years ago has been found in Juniata County.

An infestation of Emerald Ash Borer beetles was discovered along Route 333 near the Mifflin County border, in Milford Township, according to the state Department of Agriculture (web | news) . The invasive beetle has been found in 10 other counties since first appearing in Pennsylvania in 2007.

The state has imposed a quarantine on the 11 counties where the beetle was found. The quarantine restricts the movement of ash nursery stock, green lumber and any other ash material, including logs, stumps, roots and branches, and all wood chips. Because ash is difficult to identify from other tree species, all hardwood firewood and wood chips - including oak, maple and hickory - are considered quarantined.

The Emerald Ash Borer has also been detected in Allegheny, Armstrong, Beaver, Butler, Indiana, Lawrence, Mercer, Mifflin, Washington and Westmoreland counties. [...]

n addition to Pennsylvania, the beetle is attacking ash trees in Illinois, Indiana, Kentucky, Maryland, Michigan, Minnesota, Missouri, New York, Ohio, Virginia, West Virginia and Wisconsin, and is responsible for the death and decline of more than 40 million trees.

There is no known practical control for the insect other than destroying infested trees.

Connecticut funds mile-a-minute vine fight


By Robert Miller
Staff Writer
NewsTimes.com

Mile-a-minute vine, the kudzu of the North, may be less troublesome in 2010.

The [Connecticut] Department of Environmental Protection last week announced it will give New Milford $14,000 and Newtown $11,000 to fight the fast-growing and highly invasive weed.

"That's fantastic news,'' said Kathleen Nelson, who has led New Milford's fight against the vine and who had not expected the funding. "Now we have to come up with a new game plan.''

The state is paying for four invasive species projects with $115,000 from Supplemental Environmental Project payments made to DEP as part of the resolution of enforcement actions.

DEP fisheries biologist Peter Aarrestad said the DEP had to cancel some environmental grants to municipalities this year because of the state's budget crisis.

But the money received in enforcements, which the DEP can't use for its own staff or projects, was available for grants.

"We thought it was a good creative use of the money,'' Aarrestad said.

The state also gave a $78,000 grant to control fanwort -- an invasive aquatic plant -- in the Bantam River and Bantam Lake in Litchfield and a $6,000 grant to get ride of water chestnuts growing in a flood control pond in Hartford. [...]

Lake Hickory, North Carolina, weed problem clearing up

By Dianne Whitacre Straley
CharlotteObserver.com

Lake Hickory is having fewer problems with aquatic weeds and algae, according to state water quality studies.

An invasion of parrotfeather weed, which limited boating and threatened the supply of drinking water six years ago, is under control, a state water quality staff member says. And algae is no longer causing complaints of foul odors and bad-tasting water, said Kevin Greer, assistant public services director for the city of Hickory.

Greer credited better efforts at reducing the amount of runoff heading to Lake Hickory as an important step in reducing algae. Runoff may be carrying fewer nutrients, which feed algae growth, he said.

Erosion control in Catawba County and counties upstream from Lake Hickory has helped, said Greer, who reported recently to the Hickory City Council on the state studies.

The construction of more low-lying areas called rain gardens has slowed the rush of storm water, allowing it to soak into the ground rather than pour into the reservoir. Rain gardens, like one built behind Lowe's home improvement store in the Viewmont section of Hickory, are important in controlling runoff from large parking lots that cannot absorb rainwater.

Nutrient levels in Lake Hickory have not worsened, even through the area is becoming more developed with homes, where the fertilizers used on lawns end up in the lake. "I think people are getting smarter and are using less fertilizer," Greer said.

Lake Hickory has not had a problem with the invasive aquatic weed parrotfeather in two years, Greer said. The plant is a native of South America and is sold for use in ornamental fish ponds. No one is knows for sure how it got into the lake.

Duke Power biologists spotted a 2- to 3-acre growth of parrotfeather in Lake Hickory in 2001 and alerted the state. By 2003, the weed covered 125 acres.

The weed was so thick near the U.S. 321 bridge in 2003 that boaters could not reach the nearby marina. Hickory was concerned the acres of weeds would clog the pipe that carries water from Lake Hickory to the city's water treatment plant. Dense growth of parrotfeather can provide breeding grounds for mosquitoes and worsen water quality and fish habitat.

In 2004, 2006 and 2007, the city and the state shared the cost of spraying the herbicide Komeen, which has been successful in stopping parrotfeather, said Rob Emens, an environmental specialist in the weed program of the N.C. Division of Water Resources.

"It was amazing we could get it under control so quickly," Emens said.

Some weeds have washed downstream and rooted in Lookout Shoals Lake, where they have been largely controlled with sterile grass carp that were introduced by the state. The carp eat the weed.

Emens says there is a potential for parrotfeather to return to Lake Hickory. It and other weeds are spread by boaters, who could bring it from other lakes on their trailers or propellers. In an attempt to halt the spread, the state has posted signs at boat launching ramps urging boaters to throw away any "hitchhikers" - aquatic weeds.

Aquatic plants will quickly outgrow ornamental ponds, and owners should dispose of the extra in a compost pile or garbage can. Do not toss aquatic weeds into the lake, Emens said.

Invasive plants choking Griswold, Connecticut ponds


By DEBORAH STRASZHEIM
Norwich Bulletin

Griswold, Conn. — Studies of three major ponds in Griswold — Ashland, Hopeville and Glasgo/Doaneville — show they are infested with invasive aquatic plants that in some cases have clogged the area between shoreline and open water.

“Fanwort is particularly prevalent in all of the lakes, and it’s a particularly nasty plant because it grows very prolifically, especially in shallow water,” said George Knoecklein, who was contracted by the town to evaluate the three bodies of water along with Pachaug Pond. “By and large, most of the shallow coves are choked with this plant.” [...]

New York calls on U.S. Coast Guard to expedite action to stop invasive species

Stricter Standards for Ballast Water Discharge Can Curb Invasive Species Pathways

Looking to stop the rapid spread of invasive species, New York State Department of Environmental Conservation (DEC) Commissioner Pete Grannis today urged the U.S. Coast Guard (USCG) to expedite new restrictions on the ability of ships to discharge ballast water in America's waters.

"The establishment of a strong, environmentally protective, national ballast water discharge standard is a critical and necessary component of the nation's invasive species programs," said Grannis.

One of the principal ways that aquatic invasive species move around the globe is by figuratively hitchhiking in the ballast tanks of ships. Most of the 180 known species that have invaded the Great Lakes arrived via ballast water from international shipping. Some of the well-known species include zebra and quagga mussels, round gobies, spiny and fishhook waterfleas, and bloody red shrimp.

The USCG is currently accepting public comments on draft regulations on the treatment standards for ballast water used by ships ("Standards for Living Organisms in Ship's Ballast Water Discharged into U.S. Waters") through Dec. 4.

"New York State and its many partners are striving to put effective prevention measures in place for all invasive species," said Grannis. "We do this one pathway at a time - by understanding the ways plants and animals are moved around the globe by humans and then finding practical ways to shut off those pathways. Ballast water has been long-recognized as a major conduit for an ever-growing list of aquatic invasive species and we must constrict the flow as soon as we can.

New York has supported a federal proposal to require ships to treat ballast water before it is discharged (a standard known as "1000 X IMO" or one-thousand times the International Maritime Organization standard). New York issued a water quality certification making this standard appliable for all vessels traveling in New York Waters. However, Commissioner Grannis raised concerns that the time frame for implementing the standard set forth in the Coast Guard draft regulations is too long - for some ships, it wouldn't be fully phased in until 2025 - to adequately protect our waters.

Currently, New York is one of three states to enact a ballast-water standard that is more protective than federal standards. In the submitted testimony, Commissioner Grannis said that to ensure uniformity across the board, ballast water should be regulated under a strong federal program and not on a state-by-state basis. The establishment of a national discharge standard equivalent to the most stringent state standards currently in place would result in a consistent national regulatory framework for vessels that navigate in U.S. waters. In addition, the establishment of a strong, environmentally protective standard will result in the development and production of advanced technology to meet product demand, the commissioner said.

DEC has worked collaboratively with the state Attorney General's Office, as well as other states, especially the Great Lakes states and California, in efforts to influence federal actions to address the risks and dangers associated with ballast water and the need for stricter federal regulations.

Additional information about these regulations is available at http://www.uscg.mil/hq/cg5/cg522/cg5224/bwm.asp on the USCG website.

"Great Invaders" workshops in Florida

By MARK ESTES, Correspondent
News-JournalOnline.com

Great_InvadersMore than a dozen concerned local residents came to Gamble Rogers Memorial State Recreation Area at Flagler Beach on a recent Saturday to learn about a growing problem -- the invasion of non-natives into Florida.

No, it wasn't about snowbirds. The program, called "The Great Invaders," was a free five-hour workshop for homeowners on dealing with invasive exotic plants.

"Invasive plants are an ongoing problem for us, so we decided to promote education on the subject," park service specialist Terri Newmans said. "We want to encourage volunteers to help us clean exotics out of the park and at home."

According to Newmans, the Recreation Area's biggest invasive problem involves the Brazilian pepper and lantana, although there are other invasive plants present.

"We have some air potato and others, but Brazil pepper and lantana are the big problems," Newmans said.

Maia McGuire, Florida Sea Grant Extension agent, opened the program with a discussion of what invasive plants are and how they are designated invasive. She passed around samples of a number of invasive species. A plant is native if it was growing in Florida prior to the arrival of Europeans. All others are considered non-native or exotic.

"Non-native or exotic is not necessarily bad, it simply means they were introduced to this area," McGuire said. "However, if they have a negative impact, then they can become classified as invasive."

The Florida Exotic Pest Plant Council updates the list of problematic plants every two years. Category I plants are invasive exotics that are altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives.

Category II invasive plants have increased in abundance or frequency but haven't yet altered Florida plant communities to the extent shown by Category I plants. [...]

Repeat performance


WHAT: A second presentation of "The Great Invaders" workshop on invasive plants

WHEN: 10 a.m. to 3:30 p.m., Saturday

WHERE: Gamble Rogers Memorial State Recreation Area at Flagler Beach.

FOOD: Participants are encouraged to bring a picnic lunch.

HOW TO REGISTER: Call park service specialist Terri Newmans at 386-517-2086 or e-mail her at terri.newmans[at]dep.state.fl.us.

Residents in New Hampshire rally behind proposal for milfoil control funding

by Erin Plummer
NewHampshireLakesAndMountains.com

MOULTONBORO — Town residents are rallying behind the formation of a new committee and the proposed creation of a reserve fund to control milfoil.

Peter Jensen with Conservation Commission Chair Bob Clark and other residents made a presentation to the Board of Selectmen on a proposal for addressing milfoil infestation in Lake Winnipesaukee and other town water bodies.

Jensen said Amy Smagula, Exotic Aquatic Species Coordinator with the Department of Environmental Services, mapped out around 200 acres of milfoil in the 68 miles she examined.

Jensen said that of the properties on the town's current $2.85 billion valuation, 71 percent are on the shoreline and 16 percent have water access. The properties that are not located on the water have owners that still utilize the lake's resources. Studies have shown that valuations in towns with milfoil infestation can go down between 10 and 20 percent. A drop of 7 percent in the property value due to milfoil could mean a reduction in revenue of $1 million, with that figure tripling if revenue drops 13 percent.

Clark helped form a milfoil committee to address the management of milfoil in Moultonboro and around Lake Winnipesaukee. Jensen said the committee is asking that a milfoil reserve fund be formed in 2010 and money be deposited for the treatment and management of milfoil. The typical cost of a state-approved method of treatment is between $80,000 and $91,000. The committee is requesting that $100,000 be put into the fund to support the effort at the town level. [...]

Jensen said the money in the reserve fund can be used for a greater town effort but can also be available to smaller control projects that need it. The funds would also go toward control and prevention of re-infestation, as total eradication is near impossible.

"The cost of not doing it seems to be much higher than the cost of doing it," Jensen said.

Karin Nelson of the Lee's Pond Association said the hope is to have a plan of attack and perhaps a vacuum so that milfoil starts being removed from the pond, which has a heavy infestation. [...]

The fund's creation will need to be an article on the 2010 town warrant, an article selectmen said should be a petition article. Board members said including an item that size in the budget would likely not be the best course, especially with economic constraints and concerns over the future of the town's role in school funding. Board members said they would support the article.

Other associations have or have expressed interest in turning in petition articles for milfoil control and the matter of having a blanket article for all areas was discussed.

EPA Proposes New Pesticide Labeling to Control Spray Drift and Protect Human Health

Release date: 11/04/2009
Contact Information: Dale Kemery kemery.dale[at]epa.gov

WASHINGTON – The U.S. Environmental Protection Agency has rolled out proposed guidance for new pesticide labeling to reduce off-target spray and dust drift. The new instructions, when implemented, will improve the clarity and consistency of pesticide labels and help prevent harm from spray drift. The agency is also requesting comment on a petition to evaluate children’s exposure to pesticide drift.

“The new label statements will help reduce problems from pesticide drift,” said Steve Owens, the assistant administrator for EPA’s Office of Prevention, Pesticides and Toxic Substances. “The new labels will carry more uniform and specific directions on restricting spray drift while giving pesticide applicators clear and workable instructions.”

The new instructions will prohibit drift that could cause adverse health or environmental effects. Also, on a pesticide-by-pesticide basis, EPA will evaluate scientific information on risk and exposure based on individual product use patterns. These assessments will help the agency determine whether no-spray buffer zones or other measures – such as restrictions on droplet or particle size, nozzle height, or weather conditions – are needed to protect people, wildlife, water resources, schools and other sensitive sites from potential harm.

In addition to the draft notice on pesticide-drift labeling, EPA is also seeking comment on a draft pesticide drift labeling interpretation document that provides guidance to state and tribal enforcement officials. A second document provides background information on pesticide drift, a description of current and planned EPA actions, a reader’s guide explaining key terms and concepts, and specific questions on which EPA is seeking input. These documents and further information are available in docket EPA–HQ–OPP–2009–0628 at http://www.regulations.gov.

In a second Federal Register notice, EPA is also requesting comment on a petition filed recently by environmental and farm worker organizations. The petitioners ask EPA to evaluate children’s exposure to pesticide drift and to adopt, on an interim basis, requirements for “no-spray” buffer zones near homes, schools, day-care centers, and parks. EPA will evaluate this new petition and take whatever action may be appropriate after the evaluation is complete. For further information and to submit comments, please see docket EPA-HQ-OPP-2009-0825 at http://www.regulations.gov.

Invasive Asian carp one flood away from Great Lakes

Jennifer Janssen
AnnArbor.com

Advocates for the Great Lakes at the National Wildlife Federation are worried that all of the work to restore the Great Lakes could come to nothing if immediate action is not taken to keep Asian carp from invading Lake Michigan.

Only a narrow floodplain lies between Asian carp in the Des Plaines River and the Chicago Sanitary and Ship Canal that leads directly into the Great Lakes. In September, researchers found the first evidence that the carp may be present in the Des Plaines dangerously far north of an electric barrier in the canal.

One flood is all it will take to merge the waters of the Des Plaines and the nearby Chicago Sanitary and Ship Canal -- allowing the invasive carp direct access to the Lakes. This is not a far-fetched scenario — flooding merged the two waters in 2008 and 2007. [...]

Great Lakes advocates are urging that a barrier must be built immediately on the low, narrow strip of land between the potentially carp-infested Des Plaines River and the Chicago Sanitary and Ship Canal. Temporary fixes, including sandbags or an earthen berm are necessary to keep Des Plaines waters and carp out of the Great Lakes in the coming weeks and months.

Fortunately, Congress just approved funding and authorization for the Army Corps of Engineers to take emergency action to protect the Great Lakes from invasive species. However, that is no guarantee that a barrier will be constructed in time - before the next flood.

To learn more about the Asian carp and invasive species solutions, visit the Great Lakes Regional Center.

Garlic farmer uses compost harvested from invasive plants at Carding Mill Pond

By Nancy Hershfield/Special to the Town Crier

SUDBURY, MA - While others are completing their harvesting, Sudbury resident Michael O’Connor is just beginning to get his crop in the ground. Fall is planting season for garlic, and O’Connor is planting his new garlic field off Dutton Road (the field runs along the northwest side of Carding Mill Pond). He expects to have 15,000 cloves planted by Veteran’s Day, which he hopes will result in close to a ton of garlic next July.

Under a license from the town to farm the field, O’Connor is looking to supply area gardeners and farmers with localized, acclimated, organically grown hard-neck seed garlic in a limited amount by next summer. His garlic farm, Old Sudbury Garlic Farm, plans to distribute its handcrafted garlic through local farmers markets and online.

What’s special about his farm, explains O’Connor, is its sustainable cycle of local fertilizer and farm fields. To help grow his fields, O’Connor is composting invasive plant species harvested in August from adjoining Carding Mill Pond for "good use" in his garlic beds.

Invasive weeds, like water chestnuts, duck weed (Lemna), Hydrodictyon and Elodea canadensis, have been overrunning Carding Mill Pond behind Wayside Inn for years, causing fish to die from lack of oxygen and forcing many birds and waterfowl to leave during the summer because they can’t swim through the overgrowth. For the past six summers, the Hop Brook Protection Agency (HBPA) has been spearheading a harvesting project to rid the pond of the weeds so more wildlife can return to the pond.

Harvesting Carding Mill Pond

Every summer, HBPA borrows an aquatic plant harvester and conveyor from the U.S. Fish and Wildlife Service, Great Meadows National Wildlife Refuge (GMNWR) to cut the weeds. The harvester looks like a large floating lawnmower, and has underwater blades that cut the weeds and a conveyor belt that collects the vegetation. The vegetation is then transferred onto a shore conveyor belt, which transfers the weeds into a dump truck the Sudbury Department of Public Works provides. This year the harvester took out 57.5 truckloads of vegetation from the pond (nearly half the amount compared to last year).

"There is a real beauty in using the harvested material from the mill pond as composted organic matter for the neighboring farm field," said O’Connor. "It is a sustainable cycle of local material that is inexpensive, organic, abundant and very beneficial to the soil. Along with the re-mineralization of the fields, I believe that it will dramatically boost the strength and activity of the soil web, the result of which I hope will be exceptionally nutrient dense vegetables."

Pembroke, MA pond treatment could affect endangered species

By Steve Annear
Pembroke Mariner & Reporter
Thu Nov 05, 200

Pembroke, MA - Treatment of invasive plant growth in Oldham Pond will be delayed following the discovery of an endangered species of mussel in the pond.

The Pembroke Watershed Association received word from the Natural Heritage and Endangered Species Program (NHESP), part of the Massachusetts Division of Fisheries and Wildlife, on Oct. 22 that the copper sulfate used to treat the invasive plants could have “short and long-term damage” on the species.

“They found the Eastern Pond Mussel, they are saying the copper sulfate can’t be used in the pond because it could effect it,” said Ray Holman, president of the PWA.

According to the NHESP, the proposed treatment would result in interference with eating, breeding, and migratory behavior and poses a risk of harming the rare mussels.

Holman said the PWA would have to come up with some other way to treat the pond, now that a copper sulfate treatment is not an option.

Aquatic Control Technology Inc., the company hired by the PWA to treat the pond, was scheduled to begin pond treatment last summer. The company had to hold off while a mussel biologist investigated the pond to see if two rare species were living there. Only one was discovered, the Eastern Pond Mussel.

The PWA will hold the $12,660 reserved for treatment, which was approved by Town Meeting voters last May.

According to Holman, they will hold onto the money until an alternative option is offered.

“Some money has already been spent for all these different things being done between Aquatic Control. We just have to wait and come up with something,” he said.

Great Lakes get $475 million funding boost

Environmentalists laud additional federal funding

By Jerry Zremski
News Washington Bureau Chief
Updated: November 06, 2009

WASHINGTON — The Great Lakes will get an unprecedented boost in federal funding now that President Obama, almost unnoticed, has signed bipartisan legislation.

Obama approved the $475 million, one-year infusion of funding for the lakes last week when he quietly signed an annual spending bill for the Interior Department and environmental programs, which include his Great Lakes Restoration Initiative. [...]

The funding greatly enhances the odds that Buffalo will receive federal funding for a $60 million project to remove contaminated sediments from the Buffalo River, said Julie O’Neill, executive director of the Buffalo Niagara Riverkeeper.

It also boosts the chances of winning local funding for a habitat rehabilitation project on the Niagara River, O’Neill said. Buffalo is in a better position than many communities in bidding for federal money for such projects because matching local funds already have been specified, she said.

The $475 million represents nearly a doubling of the previous annual federal commitment to the lakes.

In addition to funding the cleanup of contaminated sediments, the money will help to restore wetlands and other wildlife habitats and to prevent flooding. It also will be used to try to stop invasive species such as the Asian carp, which is threatening to invade Lake Michigan from the Illinois River. [...]

Sen. Charles E. Schumer, D-N.Y., said the money will provide a long-term boost to the region’s economy. “Cleaning up the Great Lakes will allow the region’s fishing and tourism industry to grow, providing much-needed jobs and millions of dollars in revenue,” he said.

Rep. Steven C. LaTourette, R-Ohio, said on the House floor last week that the money was the first major federal commitment to the Great Lakes since he came to Congress in the mid-1990s.

But support for the measure was not unanimous among the region’s congressional delegation. Rep. Chris Lee, R-Clarence, voted against the spending bill that included the Great Lakes money.

Lee said that he supported the Great Lakes effort and had signed letters lobbying for it but that he could not vote for the legislation that included the money because the $32 billion measure was 17 percent bigger than the previous year’s spending bill for the same programs.

“I’m all for supporting the environment, but this bill was spending money we didn’t have,” he said. “It was excessive in its nature.”

The Interior Department spending bill probably won’t be Lee’s only opportunity to vote for increased Great Lakes funding. In February, Obama is expected to propose a budget for the next federal fiscal year that will include another increase.

“The fact that this is just the beginning of a five-year, $5 billion commitment is a very exciting thing,” O’Neill said.

Kudzu-eating pest found in northeast Georgia


By Sharon Dowdy
College of Agricultural and Environmental Sciences University of Georgia

Researchers from the University of Georgia and Dow AgroSciences have identified a kudzu-eating pest in northeast Georgia that has never been found in the Western Hemisphere. Unfortunately, the bug also eats legume crops, especially soybeans.

The bug has tentatively been identified as the bean plataspid (Megacopta cribraria), a native to India and China. It is pea-sized and brownish in color with a wide posterior, said Dan Suiter, an entomologist with the UGA College of Agricultural and Environmental Sciences.

“It kind of waddles when it walks on a surface, but it flies really well,”
he said.

It’s also commonly called lablab bug and globular stink bug. Like its distant cousin the stink bug, when threatened, it releases a chemical that stinks.

Suiter and CAES diagnostician Lisa Ames first saw the pest when samples were sent to them in mid-October from UGA Cooperative Extension agents and pest control professionals in Barrow, Gwinnett and Jackson counties. Samples have since arrived from Clarke, Hall, Greene, Oconee and Walton counties.

Homeowners first reported the pest after finding large groups of the bugs lighting on their homes.

“At one home in Hoshton, Ga., we found the bugs all over the side of a lady’s house,” Suiter said. “There is a kudzu patch behind her home that provides food, and they were attracted to the light color of the siding. At this time of year, the insects are most active in the afternoon when it gets warm.”

In addition to homes, the bug is attracted to light-colored vehicles.

The week the bug samples arrived at Suiter’s lab, Joe Eger was visiting. The Dow AgroSciences field biologist has 35 years of experience studying the bean plataspid insect and has named new genera and species and identified the insect for museums across the world.

Eger’s identification was confirmed by David Rider at North Dakota State University and Tom Henry at the Smithsonian Institution.

Suiter believes the bug arrived here by accident.

“We do have the world’s busiest airport here, but we’ll never know how the bug first got here,” he said. “When it found kudzu here, it found a food source, and it doesn’t have any natural enemies here that we are aware of.”

Suiter says the pest’s populations are, for now, contained to northeast Georgia. It’s an “invasive species feeding on an invasive species.”

“We have no idea what the long-term impact on kudzu will be, but we also have to consider the fact that it feeds on crops, too,” he said. “It’s kind of a double-edged sword. It eats kudzu, which is good, but it also stinks and gets on homes. The ominous threat is that it eats soybeans and other legume crops.”

“We will be working with the University of Georgia and USDA to find the best way of dealing with this insect,” said Georgia Commissioner of Agriculture Tommy Irvin. “At this time, there is not enough information to determine its current range and what its potential as a pest may be.”

Representatives of each agency met this week to form an action plan. Information has been sent to Extension agents and pest control companies across the state.

County agents are asked to look for the bug, scout kudzu patches and report any findings to Suiter. Homeowners who find the pest should call their local Extension office at 1-800-ASK-UGA1.
