Beetles released to attack invasive species

By KEITH WHITCOMB JR. / Bennington Banner

POWNAL, VT -- About two millimeters long and appearing as black specks, the town's newest 379 residents are here to hopefully stay and perhaps eat a few unwelcome newcomers.

On Thursday, two people from the Department of Forests, Parks, and Recreation released nearly 400 Laricobius nigrinus (small black beetle) onto four hemlock trees on Mason Hill Road, near the Massachusetts state line and next to a tributary to the Hoosic River. Jim Esden, forestry specialist for the department, said he hopes the adult beetles will survive the winter and feed off the hemlock woolly adelgid, an aphid-like insect that has been spreading slowly northward and was reported in Pownal over the summer.

The adelgid is an invasive species and threatens the health of hemlock trees, said Esden. The small black beetle, a native of the Pacific northwest, eats nothing but adelgids and follows a similar life cycle, being active in the winter when it is not too cold and remaining largely dormant in the hot summer. Esden said chemicals can be used to kill adelgids, but biological controls have their advantages.

"Because this is a water supply area, we didn't want to use chemicals," Esden said.

The four hemlock trees sit off Mason Hill Road on property owned by Williamstown, Mass. Esden said the water source serves as an emergency supply for Williamstown, making the chemical option less than desirable. ...

Barbara Burns, forest health program manager for the department, placed about 100 beetles on each hemlock tree, which were selected for their health and adelgid infestation. She said the beetles need enough adelgids to eat, otherwise their population will not take hold. She said the beetles released Thursday were grown in a lab by Virginia Tech, Va., however their ancestors are from Idaho. They came in small tubes, roughly 100 beetles to a tube, and were gathered on white shreds of paper for placement onto each tree.

Esden said the beetles only eat adelgids and nothing in this area specifically preys upon the beetles, so the odds are fair they will not all be eaten by spring. He said this same type of thing was done three years ago in Windham County, but it that is not enough time to tell if the beetles are working. He said their use has been documented in the past and shown to work, and while they are slow to take effect, the spread of the adelgid is not fast, either. According to Burns, the beetles' presence in Pownal is the first time they have been seen in Bennington County. ...

Maryland takes aim at invasive plants - New regulations will lead to ban on some species

by Holly Nunn, staff writer
Gazette.Net

Marylanders may know about kudzu, the invasive ivy that can be seen choking trees along highways from Texas to New England. But there are species imported from other regions or countries that also threaten the native landscape, and the Maryland Department of Agriculture is proposing regulations to identify and rank floral invaders.

In 2011, the General Assembly passed legislation establishing the Invasive Plants Advisory Committee, charging that committee with establishing a framework for assessing how much risk a given species poses to the environment.

The framework chosen by the committee is based on the U.S. Department of Agriculture Animal and Plant Health Inspection Service’s weed risk assessment protocol, but also will take into account Maryland-specific risks.

The federal framework ranks a plant’s potential to spread, its economic impact and its risk of changing the environment or affecting human health.

Based on the risk assessment that the department adopts, invasive plants will be designated as either Tier 1 or Tier 2.

Under the regulations, Tier 1 plants will be banned from being sold, and Tier 2 plants will require labeling at the retail level. Landscapers also will be required to notify their clients of any Tier 2 plants being used, said Carol Holko, the Maryland Department of Agriculture assistant secretary for plant industries and pest management and a committee member. ...

“The department is taking public comment on the risk assessment regulations until Dec. 17.

No. 1 Deer Predator in Michigan is a Surprise

by North American Whitetail Online Staff

If you had to guess which predator would be the top whitetail consumer in Michigan, you’d probably guess wolves — and to be fair, that’s not a bad guess. However, biologists say that’s not the case.

A study by Wildlife Ecology and Management at Mississippi State University, in association with the Michigan Department of Natural Resources, found that coyotes are the top whitetail fawn predators in the western Upper Peninsula, followed by bobcats in second. Wolves came in fourth behind a three-way tie of hunters, unknown predators and undetermined causes. ...

Swans Gone: Pair of swans killed to protect Fairhaven, MA marsh life

By BETH PERDUE
SouthCoastToday.com

FAIRHAVEN — The killing of two swans to protect restored marshland at Atlas Tack has angered and saddened some local residents many Two swans known to inhabit a pond at the Atlas Tack site were killed late last year by a federal agency because they were eating and destroying vegetation that was part of clean-up efforts.

The swans were killed only after state and federal agencies unsuccessfully sought out other methods to deter them, according to a spokesman from the Massachusetts Department of Environmental Protection who confirmed the deaths.

Atlas Tack underwent a $21 million clean-up process that included restoration of wetlands area at the site, said Joseph Ferson, MassDEP spokesman, in a statement.

“During this early stage of development, wetlands resources like this are fragile and require more protective measures to ensure their long-term viability,” he said in an e-mail. “At this early precarious stage, the wetlands restoration was subjected to predation by mute swan, an invasive species to the area.”of whom often watched the beautiful birds while using the Fairhaven bike path. ...

Mighty hemlocks falling to tiny, hungry insects

Tennessee's giant trees being attacked faster than expected

By Anne Paine
The Tennessean

Only a small portion of the state’s hemlocks — many that are hundreds of years old and stand 10 stories or higher — are expected to survive a scourge of tiny insects that has advanced here from the Northeast.

Chemical treatments are needed one tree at a time, and there’s only so much money and time available.

Many of the long-lived evergreens already have died or are dying in Great Smoky Mountains National Park and elsewhere, leaving needleless gray hulks that no longer shade creeks and threaten to fall on whatever is nearby.

And the woolly adelgids — named for the clumps of whitish wax fibers they produce — are progressing more quickly than officials calculated across the Cumberland Mountains and Plateau toward some of the state’s best-known scenery and hiking spots. The fast-reproducing Asian species has no native predator here. ...

Mile-a-Minute vine spotted in Norwalk, CT

By ROBERT KOCH, Hour Staff Writer

mileaminuteAn invasive species of plant has invaded Norwalk, and officials are warning residents to take action. While the Mile-a-minute vine might recall images of ivy-covered buildings, it's hardly an innocuous plant species.

"The plant is called the Mile-a-minute vine--or devil's tearthumb--because it prolifically grows up to six inches in a single day, overwhelming other species by blocking the sunlight and by the sheer weight of the weed's leaves and stems," said Marvin Moss, Norwalk Tree Alliance spokesman. "Christmas tree farms are vulnerable. So are seedlings planted for forestry regeneration and even nurseries and farmland."

The tree-killing vine has been located on Sheffield Island, on private property on Blue Mountain Road, and in the easement for the power lines of the Connecticut Light & Power Co. substation on East Rocks Road, according to the Tree Alliance.

Periscaria perfoliata -- the Latin name of the plant -- originated in Japan. It has been spread over the years in the United States by birds and ants. The vine is identifiable by its light green triangular-shaped leaves, small curved barbs on the stems and the saucer-shaped leaves.

It is generally found on the edges of woods, wetlands, stream banks, roadsides and uncultivated open fields. The vine attaches itself to other plants with its barbs, and extends upward to capture light. Flowers and deep blue berries emerge each season.

The Mile-a-minute vine poses danger for both public and private trees, according to Dave Tracy, president of the Norwalk Tree Alliance.

"It's a real sunlight hog," Tracy said. "We are hopeful that Norwalk's residents will help us to spot any infestations, so the spread of the vine can be minimized or even reversed."

The Mile-a-minute vine also has been reported in Stamford, Greenwich, Westport, Weston and Monroe. Early detection and rapid response can lessen the ecological damage of the Mile-a-minute vine, according to Logan Senack, invasive plant coordinator at the University of Connecticut at Storrs.

"Finding populations early can make control and removal much easier, less expensive and less time-consuming," Senack said.

Harold F. Alvord, Norwalk's tree warden and director of public works, said the vine "poses a significant threat to the progress the city has made over the past few years to enhance the health and vitality of the urban forest." The vine can overtake a tree in a single season, he said.

"We urge residents to report any sightings," Alvord said.

Reports can be made to the Norwalk Customer Service Center online at customerservice@norwalkct.org, or by calling the center at (203) 854-3200.

Mass. bill would protect lakes


By David Pepose, Berkshire Eagle Staff

PITTSFIELD, MA -- When state Sen. Benjamin B. Downing filed a bill in June regarding invasive species in lakes and ponds, it might have seemed quaint.

But two months later, with zebra mussels in Laurel Lake, Downing suddenly seems downright prescient.

Downing, along with state Rep. William "Smitty" Pignatelli, D-Lenox and lake association members from central and western Massachusetts, testified on the bill on Thursday at the Statehouse. From there, it could move on and eventually become law.

The bill would target anyone launching a contaminated boat -- or someone who fails to disinfect their boat within 30 days of launching into contaminated waters -- into the state's lakes and ponds.

According to the proposed legislation, penalties could entail a fine between $50 and $300, imprisonment for up to 60 days, or both.

"[Senate Bill] 2113 aims to halt the spread of aquatic, invasive species throughout our lakes and ponds," Downing said in his testimony. "The bill is especially timely due to the recent discovery of zebra mussels in Laurel Lake, resulting in public boat ramp closures throughout the Berkshires."

The discovery of the zebra mussels in the Lee lake last month has worried many town officials. Up to 700,000 zebra mussels can occupy a square yard, and the razor-sharp organisms can cripple a boat's motor or intake pipes. Furthermore, the infestation overtakes a lake's ecosystem, as the mussels quickly suck up all the water's nutrients.

Downing told The Eagle that when crafting this bill, he looked to states such as Maine, Connecticut, and Minnesota for reference. That said, with Maine's fines reaching up to $5,000, Downing said that he aimed for the lower end of the spectrum.

"The goal is not to fine people, it is to let people know of the challenges we face and to induce people to use our lakes in a sustainable fashion," he said. "It's about sharing in the responsibility of keeping our lakes and ponds as clean as possible."

Yet with resources stretched thin -- and the Massachusetts Environmental Police, the entity most likely to pursue offenders, only having 83 personnel statewide and just six officers operating in the Berkshires -- Downing admitted that the bill was only the beginning.

"Enforcement is probably the biggest challenge, both with the proposal we've put forward but also more generally when it comes to invasive species," he said.

"Minnesota has enforcement officers at all public boat ramps, but public boat ramps is only one of many access points."

Stopping the spread of invasive plants in Mass.

By Jeff Adair, The Sudbury Town Crier

SUDBURY - Volunteers including several students from Lincoln-Sudbury Regional High spent Sunday morning clearing bittersweet and other invasive plants from the area around Sudbury Town Hall and Haskell Field.

The outing was organized by White Tail Lane resident Rebecca Chizzo, founder of S.W.E.E.T., Sudbury Weed Education and Eradication Team.

"We had about ten people including myself," said Chizzo, noting that in three hours the group collected 21 contractor bags full of plant material. "We were shocked it was that much. All the rain and everything didn’t help.’’

"We’re only halfway done,’’ she added, nothing the group will hold a second outing this Sunday, Aug. 9.

Invasive plants are a major problem in Massachusetts. They displace native vegetation and disrupt habitats as they spread.

According to the Department of Agricultural Resources, an invasive species that colonizes a new area may gain an ecological edge, since the insects, diseases, and foraging animals that naturally keep its growth in check in its native range are not present in the new habitat.

Some invasive plants, such as Mile-a-Minute vine, Purple Loosestrife and Kudzu, cause serious ecological disturbances, displacing all other plants, and putting extreme pressure on native species that depend on that plant life to survive, the release said. [...]

Fungal fighter for eastern hemlock

By Joshua Brown, University of Vermont, "The View"

adelgidReaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. “This is a great one,” she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. “It’s growing really well,” she says, handing it to Scott Costa.

Costa brings the branch close to his eye. “Yes,” he says, with a boyish grin, “this is a fungus success story.”

For some, a fungus success story means nothing is growing at the back of their refrigerator. But for Costa, research assistant professor of plant and soil science, and Grassano, his graduate student, the vigorous growth in their laboratory of this fungus, a strain called Lecanicillium muscarium, means a hopeful new chapter in the otherwise bleak tale of the eastern hemlock tree.

Battling an exotic pest

From Georgia to Maine, this once-mighty conifer is now succumbing to an exotic pest, hemlock woolly adelgid. First detected in the western United States in 1924, the adelgid caused little damage. But when it was carried east and reached Virginia in the 1950s it began its destructive spread. An aphid-like insect, the adelgid kills eastern hemlocks within a few years after infestation, feeding on the sap at the base of their needles and cutting off their nutrients.

While the adelgid, originally from Japan and China, appears to have no successful predators in North America, some native fungi — like the one Costa and Grassano have growing on branches in their laboratory — kill the pest.

Last December, Costa, Grassano, and two other researchers, Vladimir Gouli and Jiancai Li, submitted a provisional patent for a new method of cheaply and effectively spreading the fungus, and other similar “biological controls,” that might beat back the adelgid without having to use expensive, toxic pesticides. They call their approach a “whey-based fungal micro-factory.”

Instead of growing fungi in a conventional factory and then transporting it out to a forest — a costly proposition — their factory will be the forest. Or, more accurately, tiny droplets of sweet whey — a cheap waste product of cheese production, inoculated with the right concentrations of the target fungus — will be their factory. By spraying the whey solution into an infected forest, they believe they can get the adelgid-killing fungi to reproduce in large numbers on its own.

“The sweet whey only costs 32 cents a pound,” says Costa, who gets his donated from a New York-based cheese company and receives support for his research from the US Department of Agriculture.

The whey is a far cheaper growing medium than those typically available in labs, and it serves as a nutritional resource, making each droplet a cozy biological factory for a fungal colony, pumping spores out into the forest long after the spraying teams have gone home.

Costa and Grassano’s experiments on branches taken from adelgid-infected forests in Massachusetts are proving highly successful, with rapid growth of the target fungi outcompeting other fungi that live on hemlocks. If their laboratory tests continue to go well, the researchers anticipate starting field trials in 2008. And beyond the adelgid, the researchers anticipate that micro-factories could be used with fungi that attack other insects, weeds and even plant diseases.

The economy and ease of the UVM team’s whey micro-factory technology may prove a critical consideration for land managers — especially in large areas with low economic value, like wild hemlock forests.

“We’re not going to eradicate the adelgid,” Costa says. “The best-case scenario for an insect-killing fungi is you inoculate the environment and get disease outbreaks to start cycling. The idea is to reduce the pest population to a level that is manageable, allowing some of the trees to make seeds, grow and survive.” [...]

Prevention is the Name of the Invasive Species Game, According to Sen. Carl Levin

Two US Senate Environment and Public Works subcommittees got an earful from Senator Carl Levin (D-Mich.) today on the threat menacing invasive species bring to the Great Lakes.

“Mr. Chairmen and Ranking Members, the impact of invasive species on Michigan’s native wildlife is large,” Levin said in a prepared statement. He waxed on about zebra mussels and big headed carp, about smelly coastlines, declining native fish populations, birds choking with botulism and foul tasting drinking water.

Levin used the platform to call for a “strong” ballast water management program. “Maritime commerce is the largest pathway for new species to be introduced into our waters, and I believe that we need to enact legislation that will require ballast water discharge management that will result in ballast water treatment technology onboard ships as soon as possible. I support establishing a strong national ballast water technology standard for all ships. Technology that meets this standard would be approved for a minimum period of time—five, eight, or 10 years,” he stated in prepared testimony.

Since pretty much anyone can use the internet to import live organisms into the country, Levin advocated for a screening process. He was really advocating for the Great Lakes Collaboration Implementation Act that he and Senator George Voinovich (R-OH) introduced because it has just such a screening process in it.

Finally, the Michigan Senator said he will introduce a bill that would simplify the process of listing a species as injurious under the Lacey Act. Listing a species under the Lacey Act prohibits the interstate transportation or importation of a species without a permit. Sen. Levin feels strongly that the bighead carp should be listed.

Since prevention is the key to saving the wildlife in the Great Lakes region, as well as many other states that are suffering both ecologically and economically from the spread of zebra mussels and other invasive species, Levin encouraged the committee to get behind these three pieces of legislation to combat the growing threat.

New "Early Detection of Invasive Species Surveillance Monitoring Field Guide"


The new "Early Detection of Invasive Species Surveillance Monitoring Field Guide" is available electronically from the National Park Service Inventory and Monitoring Program!

The guide was designed as an integral part of the Eastern Rivers and Mountains (ERMN) and Northeast Temperate (NETN) Networks Early Detection of Invasive Species Surveillance Monitoring and Rapid Response monitoring protocol. It follows the same format and is intended to be used in conjunction with the USDA Forest Service "Invasive Plants Field and Reference Guide: An Ecological Perspective of Plant Invaders of Forests and Woodlands Field Guide."

The purpose is to assist National Park Service (NPS) employees, contractors, and citizen scientists to detect incipient populations of targeted invasive species before they become widely established. The taxa presented in this guide are a subset of larger target species lists that were produced for each park in the above mentioned networks. As new park species threats arise, additional species cards will be produced.

Current species cards include:

Adelges tsugae (hemlock wooly adelgid), Agrilus planipennis (emerald ash borer), Anoplophora glabripennis (Asian longhorned beetle), Sirex noctilio (sirex woodwasp), Cardamine impatiens (narrowleaf bittercress), Dioscorea oppositifolia (Chinese yam), Frangula alnus (glossy buckthorn), Lythrum salicaria (purple loosestrife), and Oplismenus hirtellus ssp. undulatifolius (wavyleaf basketgrass).

Already in the works for next spring:

Pyrrhalta viburnii (viburnum leaf beetle), Ampelopsis brevipedunculata (amur peppervine), Lepidium latifolium (perennial pepperweed), and Populus alba (white poplar).

Boating proposal has bit too much 'mussel'

Editorial from The Republican

This is one fish tale that we just don't want to believe.

To prevent the spread of zebra mussels in the lakes, reservoirs and ponds, Massachusetts state lawmakers are considering a bill that would ban boaters and fishermen from placing in inland waterways boats contaminated with invasive species or exposed to contaminated waters in the prior 30 days unless they have been properly cleaned.

Now, we don't have a problem with that part of the bill. We think it's needed.

Zebra mussels can wreak havoc on water systems. They crowd out native species and clog water intake pipes at reservoirs. Already, the state has closed Laurel Lake in Berkshire County where the zebra mussel has been found, and boats have been banned from Quabbin Reservoir for 45 days as a preventative measure.

The mussels' sharp, small shells can also cut the feet of swimmers. Zebra mussels are more than a nuisance, and the state clearly has a duty to stop their spread.

But we have a problem with the 60-day jail sentence that violators could face should the bill pass as it's currently written. Fines yes, jail no.

State Sen. Benjamin B. Downing, D-Pittsfield, the bill's lead sponsor, said the law would create a deterrent and help educate people.

We agree, but using our jails as schoolhouses is a poor use of state money.

Instead of jailing offenders, the Legislature should use the money that would have paid for prison to station workers at state boat ramps who can inspect and clean boats before they go into the water.

We don't feel it's right to jail someone for a mistake. Legislators can write a separate, tougher law to deal with people who deliberately contaminate the water.

Legislators should think twice about tacking jail time onto the bill. Otherwise, they may end up facing bands of angry, voting fishermen who are saying to themselves "teach a man to legislate, and you've got a pest for life."

Experts seek ways to tame invasive plants

BY KELLY URBAN, The Tribune-Democrat

Invasive plants are rapidly spreading across the state and causing major problems for natural ecosystems to the point that some are changing landscapes and overtaking native species.

To better address ways of controlling and managing invasive plants, the biannual Mid-Atlantic Invasive Plant Conference being held at Pitt-Johns-town offers participants the opportunity to hear the latest findings and research on the problem.

During the two-day conference, local and national experts are covering a wide array of topics such as invasive plant management, how to prevent invasions, predicting and identifying areas vulnerable to invasion, how to distinguish between native plants and invaders, the impact of deer on ecosystems and the impacts of climate change.

U.S. Rep. John Murtha, D-Johns-town, presented the introduction to the conference Tuesday.

Murtha said that when he was a kid, people didn’t think too much about the environment and the impact it has on everyone’s lives.

“Now we have to push to get things done, and we have to work to have a clean environment,” he said.

He added that groups participating in the conference are making a real difference in combating the problem of invasive pests.

“What you do is not only a benefit to this area, but to the whole country,” Murtha said.

The conference attracts people from six mid-Atlantic states – Pennsylvania, New Jersey, Delaware, West Virginia, Virginia and Maryland, said Kristin Sewalk, a board member of the Mid-Atlantic Exotic Pest Plant Council and director of National Biodiversity of Johnstown.

“The goal is to find ways to prevent invasive plants from destroying our natural heritage,” she said. “There is still much we don’t understand, so hopefully people can take the information they hear here and apply it to their own findings.” [...]

NJ wildlife officials need help tracking invasive species

By Phaedra Laird, NBC40.net

SOUTH JERSEY--It's a creature from nearly a world away that has somehow found itself in local waterways. Experts aren't really sure exactly what kind of damage the Asian Mitten Crabs are capable of around here, but say it's important to find out more this invasive species.

"I'm trying to catch a whole lot of big crabs," said 8 year-old Gavin Vega.

"I can't complain," said his grandmother, Olga Andujar,
"everytime we come, we get some."

It's a popular pastime here at the shore, and it takes patience to find what you're looking for. "It's fun and when you catch crabs, you can eat them," said Aiyanna Vega.

"Always the same kind," said Andujar, "smaller, bigger, but always the same kind." They're catching blue claw crabs, which is what they're looking for, but what some people have been finding instead, have wildlife officials baffled. They're called Mitten Crabs, an invasive species that experts say could cause big problems here.

The mitten crabs are native to Asia and considered an invasive species here. They first started showing up in the Garden state last year in bays, creeks, and rivers. More surfaced this year, and the DEP is asking crabbers to keep an eye out and report any sightings. "I haven't seen any," said Andujar, "we come mostly every other week and I haven't seen nothing."

Experts are trying to figure out how many, and where the crabs are. They say they burrow in banks which could lead to erosion problems and fear they could interfere with other species in the area. "I never seen one yet," said Riggo Vega, "anything different, I would know right away."

State wildlife officials are asking if you do catch one to keep it, and let them know so they can try to figure out more about this foreign visitor and where it may be staying.

It's unknown how the crabs were introduced to our waters, but experts say one theory is that they may have come over from Europe or Asia by boat.

Anyone who has caught or seen one is asked to contact wildlife officials at the Nacote Creek Marine Fisheries by calling (609) 748-2020.

Invasive Asian carp close to entering Great Lakes

By Eartha Jane Melzer, The Michigan Messenger

carpThe Asian carp, an invasive species that can grow to be more than 4 feet long and 100 pounds and threatens to disrupt the Great Lakes ecosystem, has been detected within 10 miles of the electrical barrier built to keep the carp out of Lake Michigan, the U.S. Army Corps of Engineers reports.

In a statement released Aug. 7, the Army Corps warned that a new monitoring method developed by a team of University of Notre Dame scientists detected DNA from the fish in water samples taken in the manmade canal that connects the Mississippi River basin and Lake Michigan.

These findings indicate that the Asian carp may be closer to the Great Lakes than previously thought.

Earlier this year the Corps completed a $9 million electrical barrier in the Chicago Sanitary and Ship Canal. By running current through the water in the canal the agency hoped to stop the fish from entering the lakes without impeding shipping or water flow.

With news that the unwelcome fish appears closer to the Great Lakes than expected, the Alliance for the Great Lakes called for the voltage of the electrical barrier to be increased.

“The electrical barrier system has been operated by the U.S. Army Corps of Engineers at a reduced voltage of 1 volt per inch since its partial completion earlier this year,“ the environmental group said. “Current system conditions allow operation at between 2 and 4 volts, but the barrier has never been turned up that high.”

“The state of Illinois has to put an abort on Asian carp if this mission goes critical, and it needs support from the entire region,” Joel Brammeier, acting President of the Alliance said in a statement released Monday. “An ounce of prevention could save the Great Lakes from a crushing burden for decades to come — perhaps forever.”

Brammier called for aggressive monitoring of the fish and said that it may be necessary to poison the fish in the water if they make it through the electrical barrier. [...]

The Army Corps has been reluctant to operate the underwater electrical barrier at full power because of concerns that people could get shocked and that sparks could endanger cargo ships carrying flammable materials.

Corps will turn up barrier

By Dale Bowman, Chicago Sun Times

In response to the report released last week about finding DNA evidence of Asian farther upstream in the Sanitary and Ship Canal than expected, the U.S. Army Corps of Engineers will announce this morning a planned increase in the operating parameters for the electric fish dispersal barrier near Romeoville. [...]

The Corps of Engineers made the decision to increase operating parameters based on the latest, best information available, including results from preliminary genetic water testing obtained July 31st which indicate that Asian carp are closer to the barrier than previously thought. Recent research undertaken at the Corps of Engineers research laboratory indicates that the optimal operating parameters are two volts per inch, 15 Hertz frequency and 6.5 milliseconds pulse rate.

To prepare the barrier for the increase, the Corps of Engineers will begin operational testing of the equipment at 8 a.m. Wednesday, August 12, 2009. Operational testing is expected to be complete by Friday, August 14 but will continue until barrier preparation is finalized. In coordination with the Coast Guard, the Army Corps will begin navigation safety tests at the new
operating parameters as early as practicable. The timing of the increase is tied to the barrier contractor's ability to change the parameters in a safe manner.

"Once we received the genetic testing results on July 31st, we immediately began making preparations to be able to increase the operating parameters," said Maj. Gen. John Peabody, commander of the Corps of Engineers Great Lakes and Ohio River Division. "The earliest we could make the changes was this Friday, so we used the available time to consult with other state
and federal agencies and partners. It is clear to us that this is the appropriate action."

Opinion: After five years, government rules out Asian oyster gamble

From HomeTownAnnapolis.com

It's now official, or at least as official as it's likely to get. There won't be any shortcut on the winding road that may lead to some restoration of the Chesapeake Bay's embattled oyster population.

Federal, Maryland and Virginia officials announced Monday that their plans for restoring the oysters do not include introducing the so-called Asian oysters (Crassostrea ariakensis) to bay waters.

The Asian oysters grow faster, are hardier, and are supposedly resistant to diseases - MSX and Dermo - that devastated the native oysters (Crassostrea virginica), whose population is now languishing at perhaps 1 percent of historic highs. Watermen and seafood processors were excited by the idea of importing ariakensis, and the enthusiasm spread to the administration of Maryland Gov. Robert L. Ehrlich Jr.

Of course, with federal and state money involved, the idea had to be studied. And studied. And studied some more. The studying outlasted the Ehrlich administration, costing the Asian oysters an advocate.

But there was, in fact, a lot for the researchers to mull over. There is already a dismal record of unintentional introduction of harmful invasive species - from nutria to mute swans to snakehead fish - into the bay region. You can't take it back when you intentionally release an invasive species.

Many environmental scientists were leery of the Asian oysters from the start, fearing they would outcompete the native oysters into oblivion, and then turn out to have their own set of weaknesses. And there is some evidence they are more vulnerable to poor water quality and low oxygen levels - problems that would, of course, assail them in the Chesapeake.

The conclusion seemed obvious to us last October: "Unless the case for ariakensis is a slam dunk, we're probably better off trying to nurse along and revive the native oysters." The government reached the same conclusion this week.

All it took was a five-year study and $17 million in state and federal funds.

At least there won't be any more money spent on shining a flashlight down the Asian oyster dead end. But the restoration strategy the Army Corps of Engineers sketched out Monday would cost $50 million a year for 10 years - and there won't be anywhere near that much money, even if some federal stimulus funds can be used for the purpose. Since 1994, Maryland has managed about $5 million a year for oyster restoration; Virginia about $1 million.

As we've written before, if there's going to be any serious progress toward restoring the native oyster - whose usefulness as a natural water filtration system can in turn help restore the bay - a different strategy is needed. It will have to include bans on oystering in large stretches of the bay, and put more emphasis on aquaculture.

Maybe such strategies won't work. Even if they do, there may not be appreciable progress for years. But they are still a better option, and a better use of scarce government funding, than gambling on another species of oyster.

Energy from lake weeds?

By Bob Young, RutlandHerald.com

With all the debate and discussion about the future of Vermont Yankee, it's critical that Vermonters remain aware of the other ongoing efforts to ensure Vermont's energy future.

Central Vermont Public Service is among many that have urged lawmakers to give Vermont Yankee owners a fair hearing on their request to continue operations in Vermont. Yet, at the same time, we are making extensive plans for future power supplies, including planning for the possibility of Vermont Yankee's closure in 2012.

Last fall, Central Vermont Public Service, Green Mountain Power and Vermont Electric Cooperative began a broad and deep examination of power supply options for the years ahead.[...]

[...] We are also looking into energy production from lake weeds and algae, which could supplement manure in farm digesters. [...] Link

NY Senator Schumer fears Hudson Valley fishing is at risk from didymo

MidHudsonNews.com

TOWN OF KENT — While standing in a remote area of western Kent, U.S. Senator Charles Schumer Wednesday promised to sponsor legislation calling for $20 million to protect the region’s vital recreational fishing.

Schumer visited White Pond, a fishing area known for its trout and forecast a demise of sport fishing due to the didymo — a damaging invasive algae that grows in thick mats along riverbeds that smother plants along the bottom of freshwater streams depriving trout of their food, habitat and eventually their lives.

Schumer met with New York State DEC officials earlier this week and learned that unless immediate action was taken to prevent the spread of didymo, “it will spread unimpeded across the Hudson Valley.”

Schumer demanded that the Senate Appropriations Committee direct funds for the Fish and Wildlife Service to combat the didymo algae as well as other invasive plant and animal species.

He called on Interior-Environment Appropriations Committee Chairwoman Diane Feinstein and Ranking Member Lamar Alexander to “increase funding for the program to $20 million. We must and will use this funding to fight aquatic invasive species.” Link

Council to remove Egeria densa from lake in New York

Written by Matt Dalen, LewisboroLegend.com

With luck, the Three Lakes Council will soon have eradicated an invader to Lake Waccabuc. With no public comments objecting to the plan, and permission from all of the landowners involved, the town Planning Board on Tuesday, March 24 approved the council’s proposal to suck the invasive plant species Egeria densa out of Waccabuc Cove on Lake Waccabuc once the weather warms. The town Planning Board had closed a scheduled public hearing on the plan earlier this month after a short discussion of what the eradication of the plant will entail.

The proposal, which is expected to start in May and last two to three weeks, would involve divers taking suction hoses to the lake bottom over an area of about two acres, trying to remove any and all plant material that could re-start the infestation. Egeria is capable of regrowing from a small fragment of its stem, a feature that makes it desirable in the hobby aquarium but at the same time highly difficult to eradicate once it gets into an ecosystem.

In order to keep any fragments of the plant from escaping during the suctioning, the council has proposed that curtain barriers be placed around the divers performing the procedure as well as a curtain across the cove. The material harvested would go into fine net bags, which would be periodically disposed of in nearby trash bins.

A concern over the ownership of the lake bottom had delayed the approval of the project, but the Planning Board decided that the legal issues could be assuaged with letters of permission from each landowner with property on the cove. That permission has been granted, according to council Vice President Janet Anderson.

The Lake Waccabuc Association recently made a contribution of $2,500 to the Three Lakes Council’s Eradicate Egeria Initiative to help tackle the problem.

“All residents of the three lakes are being encouraged to help in this fund-raising effort.” said Ed Delaney, association president. “Although this plant so far has only been discovered in the north cove, it will eventually spread to all three lakes and it is imperative that the community as a whole deal with the problem.”

To donate to the initiative, send a check to Three Lakes Council — EEI, P.O. Box 241, South Salem, NY 10590.

Natick, Massachusetts commission nears decision on herbicide proposal

By Charlie Breitrose/Daily News staff
MetroWest Daily News

NATICK — Members of the Conservation Commission have yet to make a ruling on a plan to use herbicides in Lake Cochituate, but whichever way they go their decision will likely be appealed.

The commission on Thursday closed its public hearing on the state Department of Conservation and Recreation's plan to use diquat several times over the next five years to control Eurasian milfoil near the beach and boat ramp.

Those areas are on the north side of Middle Pond and the treatment area is within 900 feet of the town's drinking wells.

The commission asked for the Board of Health's ruling about using diquat. Based on the information, said Public Health director Jim White, the Board of Health could not support use of the chemicals.

"What we did is we put the onus on (the state) to 100 percent guarantee to us that diquat would not get into the drinking water," White said.

Warren Lyman, an expert in water chemistry who has been worked with the Board of Health in the past, said he could not recommend using the chemicals, based on the information he reviewed, White said.

The Board of Health's vote is a recommendation, White said, and the Conservation Commission is not bound to it. If the Conservation Commission approves use of diquat, the Board of Health could appeal the decision in court, but White said that is highly unlikely.

Conservation Commission member Kathy Rehl said she has similar concerns about the chemical getting into the water system.

"I have worked with plants for years and I have seen one chemical after another outlawed because they are found to cause cancer," Rehl said. "I have a real aversion to putting chemicals in a lake were we have wells."

When the proposal came to the Conservation Commission two weeks ago, people opposing and those supporting the use of chemicals gave testimony for about two hours. The appeals continued Thursday night.

Anne Monnelly, acting director of the state Department of Conservation and Recreation's water resources office, said the state had tried several non-chemical efforts to remove the milfoil, including a water circulator called a Solar Bee and placing mats over the weeds to kill them. Nothing has succeeded.

"At the request of citizens, we tried two years of the Solar Bee, three years of benthic matting and three years of hand pulling," Monnelly said. "If there was another large-scale technique that would be appropriate, I would try it."

Benthic mats block the sun, which stymies plant growth.

When the Conservation Commission approved the state's proposal to use diquat a few years ago, a group called Protect Our Water Resources appealed, and the chemical wasn't used.

Conservation Commissioner Matthew Gardner said another appeal is likely if diquat is approved.
He asked Monnelly if the state would consider dropping its proposal because an appeal is almost a certainty. Monnelly said no.

"Our thought is if you deny it, we're likely to appeal (the Conservation Commission's ruling)," Monnelly said. "We would like a ruling from the Department of Environmental Protection."
Some people have said the Conservation Commission should allow chemicals near the beach, because a swimmer could get tangled in the weeds and drown.

Martin Levin, a lawyer representing Protect Our Water Resources, said that should not be part of the commission's decision.

Levin said the onus is on the state to clear the weeds from the beach to make it safe for swimming.

"I think it is really an issue of money. The DCR is saying we don't have the money for any alternative," Levin said. "If they can't control the weeds then maybe they can't allow people to swim."
John Dwinnell, district manager for the state Department of Conservation and Recreation region that includes Lake Cochituate, said he expects use of the beach to skyrocket with the bad economy.

Most years the park draws 150,000 visitors. This year officials predict it could go as high as 250,000.

Protect Our Water Resources and the town had applied for a state grant to buy a weed-suction boat, called a DASH boat, but the proposal was denied. Monnelly said she is working with the group to see if the plan can be revived.

"We will continue to work on the DASH boat project," Monnelly said. "We are willing to do a pilot project."

The Conservation Commission also heard more comments about scientific studies showing either that diquat is safe to use or that it could pose a danger to humans.

After the public input, Conservation Commission member Douglas Shepard said he was ready to close the hearing.

"This is a typical scientific issue where you have 800 scientists on this side that say this, and 800 on that side," Shepard said.

The board will take up the proposal again April 15.

The Hemlock Woolly Adelgid (HWA), Adelges tsugae, is here! It was detected for the first time in the Finger Lakes in 2008. The HWA is an invasive forest pest imported from Asia that has been killing Hemlock trees on the east coast, often eliminating them in entire watersheds. It is a tiny aphid-like insect that forms waxy wool on Hemlock twigs at the base of the needles. The HWA will infest Hemlocks of all sizes and is readily detected on lower branches in winter and spring.

There are no area wide treatments for the HWA in Hemlock forests at this time. The only practical options are for the treatment of individual trees. Chemical treatment of urban or landscaping trees is effective and long-lasting. However, tactics for area wide control in forests that are currently under investigation, such as biological control and pathogenic fungi, will take time to fully develop and implement. We need to slow the spread of this devastating pest to buy the time necessary to complete these projects. Researchers at Cornell University, NYS Dept. of Environmental Conservation, and the US Forest Service are trying to determine the full extent of the HWA’s distribution in the Finger Lakes.

We would like anyone capable of recognizing the HWA to report BOTH positive and negative sightings. If you wish to volunteer with others organized by Cornell Plantations to inspect important local Hemlock forests please go to:

Birds in Freefall

Living on Earth - http://www.loe.org/

A new large-scale report finds roughly a quarter of all American bird species, in a variety of habitats, are in decline. But there are a few bright spots that point to potential for a turnaround. Living on Earth’s Jeff Young went visit Conn Island in the Potomac River and has our story...

...YOUNG: So what's the role of exotic invasives and bird populations?

MEHLMAN: Exotics or invasive species are one of the top threats to biodiversity of all kinds worldwide including birds. Non-native plants come in and can totally alter habitat type so it's unsuitable for use by birds and other wildlife.

YOUNG: The report shows invasive species, habitat loss and fragmentation, pesticides and disease all taking a tremendous toll on birds...

Wilmington, Delaware CBP outruns invasive bittervine

Contributed by U.S. Department of Homeland Security, featured in DelawareOnline.com

Competitive runners boast of four-minute miles, but they can’t keep pace with an invasive weed species that Customs and Border Protection (CBP) agriculture specialists intercepted at the Port of Wilmington, Del., on Wednesday.

On Thursday, a U.S. Department of Agriculture (USDA) botanist identified a weed seed, discovered during a CBP inspection of pineapples that arrived aboard the M/V Eurus Lima from Costa Rica, as Mikania micrantha, also know as the invasive mile-a-minute weed (aka bittervine).

Bittervine is reportedly an actionable federal noxious weed that can grow as much as three inches in 24 hours, and it crowds out native species.

“Our agriculture specialists immediately recognized this weed seed discovery as a potential threat to American agriculture and asked USDA for an urgent identification,” said Zachary Pillarelli, CBP Supervisory Agriculture Specialist for the Port of Wilmington. “Turns out their suspicions proved correct. I guess you can say CBP successfully outran another invasive species threat.”

CBP ordered the container secured and issued an Emergency Action Notification for the container to be re-exported. The USDA permitted the container, which was destined to Canada, to be shipped to Canada where authorities will take appropriate action. Link

8th Pepper Pull held on Saturday in Florida

Crystal River Preserve State Park, Florida, held the 8th Pepper Pull event today, sponsored by the Friends of Crystal River State Parks and the Ozello Civic Association.

25 volunteers, one staff and an Americorps IP member roved the hammocks to pull out young Brazilian Pepper trees before they can fruit.

Volunteers came from the Preserve, as well as Homosassa Wildlife Park, Ozello Civic Assoc., Native Plant Society, Audubon, and Crystal River Middle School.

After the pull everyone ate lunch provided by the Ozello Civic Association. In all, 16 additional acres were rid of 3568 pepper plants. This brings the total acreage treated with this program to approx. 103 acres and the running stem count for Pepper Pulls to over 54,000.

This type of retreatment follows the herbicide killing of adult plants by staff and contract projects, breaking the reproductive cycle in the area. This program has become an important component of a multi pronged CRPSP attack on exotics involving staff and volunteer herbicide treatments, community education and motivation, and contract control projects sourced from BIPM (FWC) and federal grants.

Volunteers sought to track tree-killers in upstate New York

ITHACA - Cornell University is taking steps to identify new infestations of invasive insect species that destroy tree populations and have encroached on New York's borders.

The emerald ash borer, hemlock woolly adelgid and Asian longhorned beetle, tree-killers with a taste for maple, ash, hemlock and willow, have been discovered in new locations all over the Northeast. The hemlock woolly adelgid (pronounced uh-DEL-jid) is already known to be in Tompkins County. The infestation was first reported in July.

Woolly adelgids were found two weeks ago around Cornell Plantations on the Cornell campus and last week in the Finger Lakes National Forest, for a total of 19 natural areas around Cayuga and Seneca lakes, said Mark Whitmore, an entomologist with Cornell Cooperative Extension.

The university has announced volunteer training sessions to help identify and report new infestations around Cornell and in Ithaca's gorges. Link

Coastal weed may be alternative energy source

By Jack Fichter, Cape May County Herald.com

VILLAS, NJ — Phragmites, the tall reeds that grow along waterways, get no respect. People poison them, burn them, tear them out of the ground with machines and they may be a cheap source of alternative energy.

Stan Smith, of Council Bluffs, Iowa is working on a project to use Phragmites to produce electricity. They grow all over Cape May County and are considered an invasive weed even though some were planted years ago by the Army Corps of Engineers to hold sand dunes together. He is South Dakota State University graduate with 20 years experience a design engineer followed by a career in product marketing and manufacturing management.

Smith said he would harvest Phragmites including the roots, grind them up and put them into a digester where microbes would eat them and create methane gas which could be used to run generators to make electricity or fed directly into the natural gas pipeline to supply homes.He points to a digester operation at the Green Valley Dairy in Krakow, Wis. where manure from a herd of 2,500 cattle is enclosed in a tank system that excludes oxygen and is broken down by naturally occurring bacteria that produces biogas.

The dairy is using two anaerobic digesters on their farm to generate approximately four million kilowatt hours (kWh) of energy a year, which would be enough to power about 400 average Wisconsin, homes for one year.

Smith suggested using the former Ponderlodge, now owned by the state Department of Environmental Protection and called Villas Wildlife Management Area, as an “east coast lab to study Phragmites.”

Barbara Skinner, who is leading a drive to save the Ponderlodge estimates there are hundreds of acres of Phragmites growing in Cape May County and several acres on the property. She has been gathering signatures on a petition to be sent to Gov. Jon Corzine requesting the lodge building and property be preserved as an environmental center.

Skinner said $4 million allocated by the state Division of Fish and Wildlife to demolish buildings and tear up asphalt pathways on the property would be better used to restore the lodge as an environmental center.DEP is taking bids for demolition of buildings before summer.

Smith also suggested the county airport as a location for a series of digesters which could produce electricity 24 hours per day. He estimates the cost to build the first digester at about $3 million but additional units would cost $1.5 million to $2 million. Link

Army official says Asian oysters plan needs more study

By Timothy B. Wheeler, BaltimoreSun.com

A key federal official has come down in favor of raising relatively small batches of sterile Asian oysters in the Chesapeake Bay while expanding government efforts to restore the bay's native oysters. But he said he would continue talks with Maryland and Virginia officials to try to reach a consensus on a policy for bringing back the shellfish.

Col. Dionysios Anninos, commander of the Norfolk District of the Army Corps of Engineers, said Friday that a five-year study by Maryland, Virginia and the federal government had failed to resolve concerns about the risks of allowing large-scale farming of the non-native shellfish. He said more studies should be done growing sterile Asian oysters in the bay before a decision is made.

Virginia's seafood industry has pressed to go ahead with full-scale cultivation of the Asian oysters, arguing that they are the best option for increasing the commercial harvest since native oysters are plagued by disease. Maryland, however, has pushed for sticking with the native species, as have other federal environmental agencies and environmental groups.

Critics say that there is a risk of reproduction even in raising sterilized oysters — and that the foreign species could cause widespread environmental damage if it took hold. Link

Asian oysters NOT headed for Chesapeake Bay

By Cory Nealon, WTKR.com

NEWPORT NEWS, Virginia - Citing insurmountable government roadblocks, the Virginia Seafood Council on Tuesday abandoned its effort to introduce Asian oysters into the Chesapeake Bay.

"Unless someone else in the state has the political will to do it, we're finished," said Frances W. Porter, the council's executive director.

Appearing before the Virginia Marine Resources Commission, Porter was expected to speak in favor of a council application to introduce 1.1 million non-native oysters into the bay starting in June.

Instead, she withdrew the application citing onerous federal and state requirements, which she declined to discuss.

The VMRC board, with the exception of Ernest L. Bowden Jr. — a waterman who said he was "deeply concerned" about the decision — offered no reaction.

The decision comes weeks before the U.S. Army Corps of Engineers, in conjunction with Virginia and Maryland, is scheduled to release a report that will guide the future of oyster cultivation in the bay.

Speaking by phone after Tuesday's meeting, Porter said the states and the corps have already decided not to allow the expansion of Asian oysters, which are fast-growing and resistant to diseases that have helped decimate the native oyster population.

"In our opinion, it is wrong," said Porter. "But it is a guiding document."

Lynda Tran, communications director for Gov. Timothy M. Kaine, said no decision has been made.

"That is certainly not accurate," she said.

Mark Haviland, a spokesman for the Army Corps in Norfolk, said the agency last spoke with council members during a conference call on Friday.

Participants discussed three possible courses of action, he said: allowing the expansion of Asian oysters, allowing nonreproductive Asian oysters, or prohibiting Asian oysters in the bay. The only decision reached, he said, was to make a unified recommendation in the report. Once the backbone of the bay's seafood industry, native oysters have declined dramatically because of poor water quality, disease and decades of heavy harvesting.

The council began introducing Asian oysters — under rigidly controlled conditions — eight years ago. It hoped to convince federal and state regulators that non-native oysters are a timelier and less expensive way to boost the oyster industry.

Several groups, including the Chesapeake Bay Foundation and the Virginia Institute of Marine Science, oppose the idea. They worry about unforeseen consequences of introducing the alien species.

Porter criticized detractors, saying they "are solely focused on the risk, not the benefits" of Asian oysters. She said the introduction of Asian oysters could help clean up the bay. Oysters act as a natural water filter.

Scientists have been working to restore the bay's native oyster population since 1993, said Tommy Leggett, an oyster scientist with the foundation. The effort, combined with more restrictive harvests, has kept the population steady in recent years, he said.

"We're seeing enough success with restoration," said Leggett, who owns an oyster farm in Gloucester County. "We're not out of the woods yet, we're a long way from that, but it's working." Link

Noxious & Invasive Vegetation Management Short Course

The second Northeastern Weed Science Society (NEWSS) Noxious & Invasive Vegetation Management Short Course (NIVM) will be held on the week of September 21st, 2009, near Harrisburg, Pennsylvania.

This course has evolved to meet the demand and need for training and instruction of professionals involved in the administration or implementation of invasive plant management in the Northeastern United States. This course is designed for public and private land managers (parks, conservancies, preserves, forests, private parcels and farms) from Maine to North Carolina who desire a better understanding of non-cropland weed management. A huge success in 2008, the course has expanded to include even more topics. This year, pre-registrants can select from a choice of topics they most want to see included in the week long event. Other topics will cover principles of vegetation management, early detection and rapid response training as well as in-depth instruction on herbicide properties, biological, mechanical and chemical tools of weed control and hands on weed identification each day.

Agricultural invaders

Inspectors at the Port of Wilmington intercept bugs, seeds, weeds that hitch rides with foreign produce

By Adam Taylor, The News Journal

WILMINGTON, DELAWARE -- A gust of wind in Costa Rica blows seeds onto a pineapple. A light in a warehouse in Chile draws a moth into a box of grapes. A locust in Afghanistan jumps onto a military jeep.

Threats to this country aren't always from the malicious hands of drug dealers, terrorists or human traffickers.

Just last week, inspectors intercepted a foreign weed and a non-native beetle at the Port of Wilmington, one of the busiest in North America for fruit imports. Foreign invaders are also an issue at Dover Air Force Base.

Had the tiny hitchhikers sneaked through, the damage could have been severe. The fast-growing weeds crowd out and kill native plants and the bugs eat everything in sight, killing crops and trees. The changes result in a chain reaction to the native habitat.

"Once an invasive plant or animal becomes established here, it becomes almost impossible to reverse," University of Delaware entomology professor Judith Hough-Goldstein said. "It's certainly something you want to avoid, because they wreak havoc and wind up displacing many of our native species."

There is a crew of six inspectors who work for Customs and Border Protection at the port who are agricultural specialists. Their job is to prevent foreign invasions.

The inspectors quietly make about 100 discoveries each year.

Wellsboro High School (PA) students include invasive species in national contest

WELLSBORO, PA. - Some local school districts are facing impending budget cuts because of the crumbling economy.

However, one school in the Northern Tier could see a sizable financial boost, thanks to a team of sharp agriscience students who are competing in a national contest.

Melanie Sanborn first learned of the Lexus Eco-Challenge, a contest co-sponsored by Toyota and Scholastic, through the internet. She thought it would be a great idea to enter her 11th and 12th grade students who are learning about the environment.

"It's an environmental contest where students are taking things that they learned in the classroom in soil, water and air quality issues, and they're applying that to their community by creating activism plans," said Sanborn.

So far, the team has won $20,000 by coming out on top in two of the challenges presented in the contest. Each challenge puts them $10,000 closer to the $50,000 goal.

Now, they are designing a native species garden to compete for the final leg of the competition.

"We designed it using some software we have," said 11th grade student Talia Cpiol. "I decided I wanted it to be completely native, so out of the 500 trees that were donated to our school by the Pennsylvania Department of Conservation and Natural Resources, I had to research each one to make sure it was native to the area," she said.

The other half of this part of the challenge involves raising awareness about invasive species, like zebra mussels in local bodies of water, and giant hogweed plants, which can wreck ecosystems easily.

"We sent out some letters to a bunch of the hunting camps around just to let them know how not to spread the stuff," said teammate Cody Owlett, who is a senior this year.

The team also will be talking to local elementary school students about how to spot and avoid spreading invasive plants or animal species.

One of them is called "Japanese knotweed." It grows in thick, with leaves the size of paper plates, so it can overshadow other plants and steal needed sunlight.

The plant can grow as tall as 9 feet. "A lot of people try to cut it down," said teammate Caleb Krick, who is also a senior. "But in like a week, twice as much grows back," he said.

"When you're walking through it, you have to wipe off your pants and shoes to make sure you don't spread the seeds." It's a lot of work, but well worth it to the students and to the school.

"I'm going to college," said Krick. "I plan on putting it towards that," he said of the share of $30,000 he might receive when and if the team wins the final chapter of the Lexus EcoChallenge.

The school will receive $10,000 for classroom purposes, and Sanborn will receive $10,000 for her agriscience curriculum.The students find out around the first week of April if they have won. They are competing with about 20 schools nation-wide in this section of the competition.

Rhode Island town takes aim at invasive beach grass

Asian sedge is taking over dunes; eradication set to begin soon

By Ted Hayes, EastBayRI.com

MIDDLETOWN, RI — No one knows for sure how it got here, but one thing is certain: An invasive species of Asian beach grass that’s creeped up around Sachuest Beach over the last few years is causing big headaches for those in charge of overseeing the scenic stretch of waterfront.

Middletown town officials will take a big step toward fixing the problem Wednesday when they open four bids submitted by companies that hope to win the job of eradicating the grass. The job, to spray areas around the Sachuest Point Road dunes that have already succumbed to the fast-moving grass with herbicide, is expected to take months to complete. Once the bids are reviewed, the Middletown Town Council is expected to approve one on Thursday, April 6.

“We’d like to get started (spraying) soon after,” said Middletown town engineer Warren Hall.

That’s not a moment too soon, according to the chairman of the Middletown Beach Commission.

Rian Wilkinson has watched the grass — most likely Carex kobomugi — grow steadily across the beach’s dunes for several years now, and it seemed to grow fast last year. It’s cropped up along the campground area to boardwalks 1, 2 and 8, he said.

The low-clinging grass is easy to spot, lying low, yellow-green, in contrast to the taller, darker native grass it’s competing with. But it’s not just an aesthetic problem, he said. The grass chokes out the other species of native grass and since it doesn’t have deep roots, it will eventually lead the dunes’ erosion, he said.

“It just takes over everything else and the dunes suffer,” he said. “It seems to have dug in over the past few years.”

Town officials received approval from the state Coastal Resources Management Council (CRMC) last year to remove the grass. Mr. Hall said treating it could be a long process.

The grass will be sprayed with a Roundup-type solution with a surfactant and coloring agent added that will keep it from running off and will make it easy to determine where it’s been sprayed.

Officials plan to treat the grass at least three times. Mr. Hall said the first treatment in April should remove about 10 percent of the grass. The second should remove another 50 percent, and the third the remaining 40 percent.

“It’s one of those things where you don’t know how effective the treatments are going to be until you do it,” he said.

That will be the scope of this project, he said. Longer-term, though, a second phase will involve stabilizing formerly infected dunes with erosion control features, and then re-planting native beach grasses.

The project is being funded by the Town of Middletown. Mr. Hall declined to comment on the expected cost until after the bids have been reviewed.

Week of March 9, 2009

Updated 3/13/09

Hemlock woolly adelgid workshop in the Finger Lakes region

An insect pest newly arrived in the Finger Lakes region, NY -- the hemlock woolly adelgid – was recently discovered in the Cornell Plantations area of Cascadilla Gorge and in the Beebe Lake natural areas and is threatening hemlock trees and the biodiversity they support. This Asian species has decimated hemlock populations across the eastern United States, where altered habitats – due to the loss of the hemlocks – have caused a cascade of environmental changes for some amphibians, fish, invertebrates and plants in response to increased light and warmer temperatures.

The hemlock woolly adelgid (Adelges tsugae) causes nearly 100 percent mortality in the native eastern hemlock (Tsuga canadensis). The small, aphid-like insects feed on the sap at the base of individual needles on the trees; eventually needles yellow and drop, branches die, and trees succumb in about four to 10 years.

Hemlock woolly adelgids were first reported in the central Finger Lakes region in mid-2008, and they now inhabit at least 19 local sites. Early detection of new sites of infestation is now a high priority, and local conservation groups are organizing volunteer surveys as a critical first step in managing this devastating invasive species.

Cornell Plantations, Cornell Cooperative Extension, the Cornell Department of Natural Resources, the Finger Lakes Land Trust, and the Finger Lakes Native Plant Society are organizing three workshops aimed at training volunteers to identify and report new hemlock woolly adelgid infestations. Each two-hour session will feature a presentation by Mark Whitmore from the Cornell Department of Natural Resources on the adelgid’s biology and the threat it poses to local hemlock forests. Participants will visit Beebe Lake to observe hemlock woolly adelgids firsthand and gain experience in detection and survey protocols. Participants will also have the opportunity to volunteer in the "Adopt-a-Hemlock" program to conduct surveys and report new infestations in local hemlock forests.

The training workshops will be held at Cornell Plantations’ Lewis Education Center, located at One Plantations Road on the Cornell campus, on Friday, March 13, at 1 p.m.; Saturday, March 21, at 10 p.m.; and Monday, March 23, at 3 p.m. To register for the training workshops, or for more information on the hemlock woolly adelgid, visit http://plantations.cornell.edu/our-gardens/natural-area/invasive/hemlock-woolly-adelgid. Additional information and instructions on reporting new infestations can also be found at the New York Invasive Species Research Institute website

Workers attack invasive plants on Thousand Islands

By Jim Waymer, FloridaToday.com

COCOA BEACH, FL -- The Aussies must go.

Tall Australian pines fell this week along Fourth Street to clear way for natives.

Brevard County's estimated $400,000 plan will remove the exotic pines and other invasive species along Fourth Street and the nearby Thousand Islands to replace them with trees and plants that belong here.

The city stands to lose a little slice of Australia, and, for the time being, some spots in the shade. But biologists say the gains in wildlife, erosion control and rekindled natural heritage should far outweigh the temporary sentimental loss.

"Our children and our grandkids will have a much healthier group of islands out there to enjoy forever," former Cocoa Beach City Commissioner Tony Sasso said. He pushed for years to protect the cluster of tiny islands south of Minutemen Causeway in the Banana River Lagoon.

The felling of the exotic pines marked a milestone in a multiyear battle to restore the islands to their previous pristine glory.

The trees' downfall also echoed the controversial removal of Australian pines from Melbourne Causeway in 2005, when the Florida Department of Transportation removed about 200 Australian pines that had lined the causeway, some more than 50 years.

Biologists say Australian pines, introduced in the 1800s, harm the ecology because they create "monocultures" that crowd out native trees. They worsen erosion, as they displace deeper-rooted native plants. They also limit bird nesting and can be toxic to native wildlife.

The city of Cocoa Beach and conservationists pushed for years to get Brevard County to buy the islands to preserve them for paddlers, osprey and egrets, instead of dream homes.

Hemlock-killing adelgids invade Tompkins County, NY

By Liz Lawyer, IthacaJournal.com

ITHACA, NY - Cornell University is taking steps to identify new infestations of invasive insect species that destroy tree populations and have encroached on New York's borders.

The Emerald Ash Borer, Hemlock Woolly Adelgid and Asian Longhorned Beetle, tree-killers with a taste for maple, ash, hemlock and willow, have been discovered in new locations all over the Northeast. The Hemlock Woolly Adelgid (pronounced uh-DEL-jid) is already known to be within Tompkins County. The infestation was first reported in July 2008.

Woolly adelgids were found around Cornell Plantations two weeks ago and last Wednesday in the Finger Lakes National Forest, for a total of 19 natural areas around Cayuga and Seneca Lakes, said Mark Whitmore, an entomologist with Cornell Cooperative Extension. The university has announced volunteer training sessions to help identify and report new infestations around Cornell and in Ithaca's gorges.

"The infestation is more widespread than we thought," Whitmore said. "We're doing the trainings basically because we want to know how widespread it is, so we can plan our response appropriately. This is a potentially devastating insect to the region's forests, and especially to hemlocks, which are a valuable resource in the region."

Part of the problem is that early stages of infestations by woolly adelgids are difficult to detect, so by the time they are found they have already been established for several years, Whitmore said.

"It's happening so fast," Bittner said. "Literally in the last week there have been two more places it's been found."

Town of East Hampton Cost of Grants Assessed

Board weighs outlay against needs of environment

By Joanne Pilgrim, The East Hampton Star

(03/12/2009) The status of environmental projects in East Hampton Town (Long Island, NY), for which the Natural Resources Department has obtained grants totaling $295,000, is under review by the town board, which, in light of a budget crisis, must determine “which grants we want to work on, and which are not worth pursuing,” according to Town Councilwoman Julia Prince, the board’s liaison to the department.

Two grant agreements that expired in 2001 and in 2003 were recently renewed by the State Department of Environmental Conservation at the town’s request “because of delays in the construction or implementation of the project,” according to a town board resolution.

To receive a $75,000 grant from the D.E.C. for aquatic habitat restoration, the town was to have completed $150,000 worth of work by Dec. 1, 2003. The tasks, some of which have been completed, included salt marsh revegetation, re-establishing eelgrass beds, damming ditches in tributaries for marsh water management, and clearing streams in Northwest to allow alewives to access breeding areas. The project also includes clearing 15 acres of phragmites growing in various harbors, creeks, and ponds, which has not yet been tackled.

The town has spent approximately $74,000 so far on the project. The new deadline for completing the tasks is Dec. 31, 2010. But town board members, discussing the issue at a meeting on Tuesday, questioned whether the “tremendous job” of removing 15 acres of phragmites could be accomplished.

A $15,000 grant for habitat restoration at Lake Montauk, which requires the town to spend $30,000 on phragmites removal and restoration efforts focused on alewives and eelgrass before the D.E.C. will kick in half, expired in October of 2001, but has been extended until the end of 2010. Link
