Feds suspend aerial tranquilizing pending necropsy results
Wildlife biologists have temporarily suspended their Mexican gray wolf count and capture operation after two wolves died during the annual population survey.
As part of the wolf recovery effort, wildlife managers tranquilize the wolves from the air to attach radio collars, which gather biological information, such as dispersal, territories, habitat use, and breeding.
This year, two of the wolves died shortly after being tranquilized. The U.S. Fish and Wildlife Service will conduct necropsies at an Oregon lab to determine causes of death for each wolf. Continue reading

Lighting ordinances help protect nesting turtles
Coastal development may still be running rampant in Florida, but there are some signs that a concerted effort to protect sea turtles from at least some of the impacts is paying off.
A study that started as a high school science project suggests that a network of sea turtle-friendly lighting ordinances along Florida’s coast seems to be working by darkening beaches, which is a big deal because scientists already know that sea turtles are disturbed brightly lit areas. The findings fit in with other studies that assess the impacts of light pollution on wildlife.
“Florida’s coastlines are getting darker, and that’s a good thing not just for sea turtles but for other organisms,” said University of Central Floria biology professor John Weishampel, co-author of the study published last week in the journal Remote Sensing in Ecology and Conservation. “It shows we affect turtles’ nesting, but at the same time we’ve been successful at reducing that effect.” Continue reading

Protection efforts pay off for the marine mammals
Federal biologists say manatees are on the road to recovery and they’re proposed to downlist the species from endangered to threatened under the Endangered Species Act.
When scientists started tracking the gentle marine mammals, the Florida population was estimated at about 1,200. In the last 25 years that population has grown to about 6,300, with 13,000 across the species’ range, including Puerto Rico, Mexico, Central America, South America, and Greater and Lesser Antilles. Continue reading

New protection to aid recovery of rare marine mammals
North Atlantic right whales will have a little more protection off the East Coast, as NOAA’s National Marine Fisheries Service expanded critical habitat to cover feeding areas in the Gulf of Maine/Georges Bank region and southeast calving grounds from North Carolina to Florida.
The expansion does not include any new restrictions or management measures for commercial fishing operations, but it would require more extensive review of any proposed activities in the region. Continue reading

USFWS proposes to revamp endangered species listing process
By Bob Berwyn
In the age of climate change, rampant consumption and development, plants and animals are going extinct faster than ever before in the history of the planet — so fast that the Endangered Species listing process in the U.S. has been overwhelmed. Continue reading

Conservation groups and the Mexican government are making progress in trying to avert extinction of the vaquita porpoise, a small marine mammal that lives only in a few thousand square miles in the northern Gulf of California.
Late last month, Greenpeace announced that several Hong Kong traders involved in selling illegal marine products from the Gulf of California were convicted and fined for their activities, which could help deter more trade in illegal marine products from the region. It’s that trade that’s pushing the vaquita to the brink of extinction.
And in the Gulf of California, the Mexican government has stepped up enforcement of a gill net ban that’s aimed at protecting the vaquita. At the same time, the Mexican government has partnered with Sea Shepherd, giving the nonprofit direct action group the authority to remove illegal gill nets. Two Sea Shepherd vessels are patrolling the region as part of the group’s Operation Milagro II. Continue reading

Climate change may bolster spotted owl survival in the future
Northern spotted owl populations continue to decline across the Pacific Northwest, researchers said in a new study showing that competition from barred owls, along with habitat destruction and climate change are all factors in population trends.
According to the research, published in The Condor, spotted owls are in decline across all of their range. The findings are based on data from 11 study areas Washington, Oregon and northern California, with a rangewide decline of nearly 4 percent per year between 1985 to 2013. Continue reading
