Can turtles win the race on Cape Cod?

WELLFLEET – Don Lewis could barely contain the admiration he felt for a female terrapin turtle, who, despite being run over by a car last week, continued to struggle inland to lay her eggs. Her shell was badly cracked on both the top and bottom. She was bleeding, dehydrated and weak after spending the night crawling towards a spot to lay her eggs on a Lieutenant Island beach.

As if loss of habitat and increased numbers of suburban predators weren’t enough, turtles get hammered as they travel to inland nesting sites by an even tougher opponent – cars.

“It is one of the major threats for our state-listed (under the state’s endangered species act) species,” said Lori Erb, turtle biologist with the Massachusetts Division of Fisheries and Wildlife.

This summer, turtles got hit especially hard, after a wet and cold June delayed nesting by a month, so that peak nesting coincided with peak summer traffic. That means more turtles getting hit as they attempt to cross roads bordering wetlands and creeks to upland nesting spots.

Read the rest of this story in tomorrow's Cape Cod Times and find out if the plucky turtle survived long enough to lay her eggs.

State studying roads, highways with high turtle mortality


GHS
Posted Jul 26, 2009 @ 12:22 AM


On Wednesday, the patient was brought to the New England Wildlife Center in Weymouth bloody, dazed and cracked.

The eastern painted turtle, a common Massachusetts species found in or near ponds and lakes, met with a truck or car on Rte. 44 in Plymouth earlier that afternoon and a passerby scooped him up to see what could be done.

Untold numbers of turtles - some on protected species lists - are killed on Massachusetts roadways each year while looking for a place to lay their eggs, searching for food or simply getting from one place to another.

A collaborative project between the state Division of Fisheries and Wildlife's Natural Heritage and Endangered Species Program and MassHighway might put an end to some of the road kill.

This spring, the state began collecting information from area wildlife scientists, advocates and motorists about areas where they see high rates of turtles killed by vehicles. When possible, the species of turtle killed is logged to see if it is endangered or protected.

When the study is complete, MassHighway and the NHESP hope to have a statewide priority list of turtle road-kill hot spots. Some of those locations could see immediate improvements, including fencing or other barriers to protect the turtles, and others would be flagged for the future when construction projects in the area might allow for more expansive measures, including wildlife tunnels.

"We know already that there are a number of very low cost design implementations that make roads safer for wildlife," said Mike Jones, endangered species review biologist at the NHESP. "We are interested in having available as a resource where these problem crossing sites occur."

"These are pretty small fixes that can really provide a great benefit to the traveling public and wildlife," said Kevin Walsh, director of environmental services for MassHighway.

Walsh said turtles in the road can be hazards to drivers who try to avoid them and get into wrecks or endanger people who run into the road to help the reptiles, "beside the fact that it's killing the turtles. Even a small number of deaths can decimate a local population."

The surge of federal stimulus money to pay for transportation projects in part made the study possible.

Walsh said Jones' position at the NHESP is paid by MassHighway's budget through an interagency agreement. The stimulus money caused a significant increase in the number of transportation projects, which all need environmental review.

Jones, who works out of the MassWildlife field office in Westborough, operates independently of MassHighway but his position "helps us have them focus on our projects and identify areas where we can improve the environment while we are out there," Walsh said.

Ron McAdow, executive director of Sudbury Valley Trustees, praised the collaboration between the two state agencies.

"I applaud this very much," McAdow said. "With turtles, it's extremely important (to protect them) because they have a very slow reproductive strategy. They lay a small number of eggs and many of those eggs can be eaten by predators. The accidental death of an adult turtle really makes a big difference in the population."

According to Jones, protected species such as wood, box and Blanding's turtles are of particular concern as well as common species such as painted and snapping turtles, which are probably declining in population.

There are two ways turtles get into trouble on roads, Jones said.

Some turtles are actually looking for nesting areas on the shoulder or median. Others are crossing the road to get to nesting areas or back to water.

In areas where turtles wander on the shoulder looking for nesting sites, a simple low barrier would keep them safer. In areas where turtles are crossing roads from waterways, a culvert or tunnel under the road might be what's needed, Jones said.

Locally, roads around the Concord, Sudbury, Assabet and Nashua rivers are being targeted, though site-specific data is not complete.

This is not the first time the state has helped turtles near roads.

Two years ago, MassHighway improved fencing along Rte. 2 in Lancaster because Blanding's turtles - a threatened species in Massachusetts - were crawling under a fence and not making it across the busy highway. There are also wildlife tunnels under Rte. 2 in Concord.

According to Dr. Greg Mertz, CEO of the New England Wildlife Center, turtles most often get hit by cars in May (when females are searching for nesting sites) and late September (when hatchlings head to water), but road kills can happen at any time.

Last week, three painted turtles hit by cars had to be euthanized at the center, Mertz said. Fifty-five turtles were brought to the Wildlife Center last year.

Those that can be saved are eventually returned close to where they were found, said herpetologist Joe Martinez, director of education at the Wildlife Center.

"But if the (pond or lake) is surrounded by roads and heavy traffic, we might look for a better location," he said.

Wednesday's patient came in with a visible crack down the middle of its shell. It appeared slightly impaired neurologically and had blood stains on its underside, Mertz said, but it might be saved.

The woman who found it, Morgan Guiliano of Manomet, said she's a big fan of turtles and this was not her first road rescue.

According to staff veterinarian Dr. Maureen Murray at the wildlife clinic at Tufts Cummings School of Veterinary Medicine in Grafton, about 80 turtles are brought in each year. A vast majority of those were injured on the road and only half survive.

Common injuries, such as shell fractures, are fixed with orthopedic wire and the turtles are released back into the wild soon after even though the bone of the shells may take a year or more to fully heal, Murray said.

With each adult turtle killed, the effect on local populations can be devastating, Murray said, because it takes 15-20 years to reach adulthood.

"Road mortalities are really a huge threat to turtle populations," she said. "Collecting data on road crossings is really important for these turtle species. I think it's a great idea."

Timer could save sea turtles from drowning in nets

The Associated Press

BOURNE, Massachusetts -- Fishery managers trying to protect rare sea turtles from dying in fishing nets have tapped a Cape Cod company to build a device they think can help balance turtle protection with profitable fishing.

The "tow-time logger" is an 18-centimetre, silver cylinder that attaches to fishing nets and records how long the net stays underwater.

That time is crucial if a turtle gets snared in the nets dragged behind fishing trawlers. Federal research indicates the vast majority of sea turtles survive entanglement -- but only if the net is pulled up in less than 50 minutes.

With the logger, regulators can avoid other, potentially more onerous, restrictions on perpetually struggling fishermen -- such as shutting down fishing areas or requiring turtle-saving gear that doesn't work well in all nets. In fisheries where they decide time limits would work best, they wouldn't have to depend on an honour system to make sure nets are pulled up in time.

"Turtles have also been around since the time of the dinosaurs," said Elizabeth Griffin of the environmental group, Oceana. "They're cool animals that I think most people want to see continue to exist."

The logger was built under a US$25,000 federal contract with the National Oceanic and Atmospheric Administration by Onset Computer Corp., a Bourne-based supplier of data loggers for energy and environmental monitoring. It starts recording water depth every 30 seconds once the net drops below two meters. If the net stays under beyond a preset time limit, the logger records it, and the infraction can be discovered when regulators download its data.

The device's early tests at sea have been successful, and work is ongoing to toughen it for the real-life rigours, such as being banged on fishing boat decks. The company expects it to cost between $600 and $800, an expense that would fall to fishermen.

Even when the logger is perfected, regulators know limiting how long the nets stay underwater is no cure-all as they devise rules, which they hope to propose for public comment by 2010, to meet a new federal requirement to protect sea turtles from trawler fishing nets.

Some environmentalists say turtles shouldn't be kept underwater at all because even relatively short times of being trapped underwater without oxygen hurt them.

Griffin says there's also not enough data on how trapped turtles fare in colder waters, so no one really knows how long they can be kept under and survive.

The data logger at least makes briefer tow times a feasible way to protect turtles, if researchers can sort out what's safe, she said.

Fishermen are skeptical. They say short tows aren't practical in most fisheries, such as those in deeper waters, where a worthwhile catch is impossible if the nets must constantly be pulled up.

"It's a bad idea," said James Fletcher, a veteran fisherman and now head of the North Carolina-based United National Fisherman's Association.

"Nobody's going to love the idea," acknowledged Henry Milliken, a biologist with the National Marine Fisheries Service, which is part of NOAA. But he added fishermen might prefer limits on how long the net can be underwater to harsher alternatives, such as closing fishing areas.

"The idea is that we're looking at providing options to the managers in the future," Milliken said.

As the NMFS tries to determine which steps will or won't work, it's held public meetings this spring from New York to Georgia.

The turtle most frequently caught in trawl nets in the Atlantic is the loggerhead, the threatened 113-kilogram giants named for their relatively large heads. In U.S. waters, every sea turtle is listed as either endangered or threatened, so any turtle deaths in fishing nets hit the populations hard.

The most common way to protect turtles right now is the Turtle Excluder Device, often a circular, barred frame attached near the front of fishing nets. The bars are big enough for fish and other sea life to slip through, but too narrow for turtles, which bounce out of the net before they get caught.

The excluder devices have had success in some fisheries, including the Southeast's shrimp trawl fishery, but bigger species, such as horseshoe crab, monkfish and flounder, can bounce out along with the turtles and make the nets far too inefficient.

Greg DiDomenico of the Garden State Seafood Association, a New Jersey trade group, said since the new rules will apply to fisheries from Cape Cod to Florida -- where the turtles swim -- whatever shakes out is bound to be felt industry-wide. That includes "huge negative impacts on some fisheries," he said.

But with regulations coming, DiDomenico said his best hope is that regulators don't broadly force a turtle-protecting solution, including the time logger being developed, on a diverse fleet.

"It's not one-size-fits-all," he said.

Turtles Get a Head Start





BUZZARDS BAY — Out in the wild, tiny northern red-bellied cooters would most certainly be lunch for skunks and raccoons.

But six turtles with fire-colored tummies were more eaters than entrees yesterday as they devoured shreds of lettuce like termites tearing through wood.

To watch a video of the colorful

capecodonline.com/capecast at noon today.

The undersized bunch arrived at the National Marine Life Center in Buzzards Bay two weeks ago with the goal of getting fatter — or at least big enough to be safely released back into their natural freshwater habitat.

In Massachusetts, northern red-bellied cooters are native only to Plymouth County — at least 250 miles north of where most of the species resides in mid-Atlantic states.

The species is endangered in Massachusetts and classified as threatened on a federal level, said Don Lewis, the center's chief operating officer.

Nearly 100 percent of northern red-bellied cooters that hatch in the wild are eaten by predators such as skunks, raccoons, herons and bullfrogs, according to the U.S. Fish and Wildlife Service Web site. Those dire survival numbers prompted federal and Bay State wildlife officials to set up a "head-starting" program for the turtles.

"They are pretty rare everywhere we look," Lewis said. "That's why we protect them, that's why we give them a head start and that's why we're trying to reverse the decline in populations."

Research biologists find red-bellied cooter nests and protect them with screens. When hatchlings start to emerge from a nest, biologists remove half of them and take them to marine rehabilitation centers where they are fed and kept warm for about eight months. They are then released to pond and river habitats. Red-bellied cooters that get a head start have a high rate of survival, according to the wildlife service.

Lewis said the center's cooters, which were born in October, are healthy and will be released when they are "hockey-puck size," likely within a month.

Turtles on the move, burying eggs in dry ground

GateHouse News Service
Posted Jun 10, 2009 @ 10:45 PM

Raynham —
June is turtle time in these parts.

Regardless of all obstacles in their path, snapping, painted, red-bellied and all other species of turtles are leaving their watery homes for higher ground to bury their eggs.

“It goes on everywhere and as long as people give them a good wide berth they won’t bother anyone,” said biologist Dick Turner of the state Division of Fisheries and Wildlife.

Last week, two slow-moving female snapping turtles from the Forge River were seen crawling across the busy parking lot outside Town Hall in search of a dry home to incubate their eggs.

But it’s a journey fraught with danger.

“With alarming frequency these ancient reptiles are cut off from traditional nesting areas by an ever-increasing network of roads, leaving them vulnerable to high rates of road kill,” explained Mass Wildlife Director Wayne MacCallum in a press release.

The report said humans can help the annual reptile migration by carefully moving turtles out of harms way. The sometimes feisty snapping turtles can be held by the tail while placing one hand on its underside to support the animal’s weight. Other turtles can be safely grasped by the sides of the shell.

Officials stressed, however, the turtles should be aimed in their intended direction and never brought to another location or pond.

But even safe passage does not ensure that a turtle and her eggs will survive. Skunks and raccoons feast on the shallow nests, which contain between 30 to 40 eggs.

Turtle biologist Lori Herb said the nests are most vulnerable to invasion during the first two weeks of being deposited by their mother.

She said a temporary fence can be used to protect the nests, but they must permit sunlight and be removed well before the hatchlings are expected to start their journey to lowland areas. “The main thing is trying to leave them alone,” Erb said.

Because of an abundance of wetlands, Southeastern Massachusetts is home to nearly every species of turtle found in the state.

But in suburban communities like Raynham, she said, development in habitat areas has put the hatchling mortality rate at almost 100 percent.
