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 bittervineContributed 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.

8th Pepper Pull held on Saturday in FloridaCrystal 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 YorkITHACA - 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.

Coastal weed may be alternative energy sourceBy 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.

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.

Asian oysters NOT headed for Chesapeake BayBy 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."

Agricultural invadersInspectors at the Port of Wilmington intercept bugs, seeds, weeds that hitch rides with foreign produceBy 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 contestWELLSBORO, 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 grassAsian sedge is taking over dunes; eradication set to begin soonBy 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.

The research by Brown University, Wildlife Trust, Pacific Lutheran University, the Centers for Disease Control and Prevention, and the Global Invasive Species Programme comes as Congress begins deliberating the Nonnative Wildlife Invasion Prevention Act (HR 669), which would tighten regulations on wildlife imports. At a hearing last week before the House Natural Resources Committee, Subcommittee on Insular Affairs, Oceans and Wildlife, wildlife experts discussed how nonnative species and plants can disrupt ecosystems. One case mentioned at the hearing involves the Burmese python, originally imported as a pet that now infests the Florida Everglades.
