New sampling method enables early detection of deadly fungus in the environment, before it infects amphibians
FRISCO — A new way to test for the presence of the amphibian-killing chytrid fungus may help conservation efforts for species like the Rocky Mountain’s boreal toads, still under consideration for the endangered species list.
Instead of testing amphibians directly for the fungus, U.S. Geological Survey researchers said they’ve learned how to test for chytrid fungus in the water the animals live in. The new sampling technique can help assess the risk of exposure, potentially helping plan recovery efforts. Continue reading

Biodiversity crisis growing as more and more species blink out
FRISCO — It’s no secret that many plant and animal species in the U.S. are in danger of disappearing permanently, but a new report from the Endangered Species Coalition brings home the point by highlighting several once-common species teetering on the brink of extinction.
Among them, the mountain yellow-legged frog, with 90 percent of remaining populations supporting fewer than 10 frogs.
“Frogs have successfully thrived on our planet since the time of the dinosaurs, but now the mountain yellow legged frog and 30 percent of all amphibian species are facing extinction due to human actions,” said Jeff Miller with the Center for Biological Diversity, which nominated the mountain yellow-legged frog for today’s report and petitioned for its federal protection in 2000.

Monitoring to help inform conservation plan
RISCO — The National Park Service hopes to protect bat populations in Great Smoky Mountains National Park with a winter closure to limit human disturbance to bat hibernacula and help hikers avoid interactions with bats.
The Whiteoak Sink area will be closed through March 31 while park biologists monitor the site throughout the winter to cllect population, ecological and behavioral data. The information will be used to develop a long-term protection plan. An extended closure through late spring may be recommended if the winter data suggests such an action would increase the chances for survival of a significant number of bats. Continue reading

Federal judge invalidates state hunting plan
FRISCO — Wyoming wolves will get at least a temporary reprieve from the state’s shoot-on-sight management plan, as a federal judge this week set aside a 2012 decision that turned wolf management over to the state.
The state plan, approved by the Wyoming legislature, would allow hunters and trappers to kill most wolves outside of Yellowstone National Park, leaving only a token population in the park — hardly in keeping with the spirit and intent of the Endangered Species Act. Continue reading

Report shows that even many common species are dwindling
Global warming threatens ptarmigan habitat in the mountains of the West.
FRISCO — Bird populations are dwindling all over North America, especially in the Southwest, where some species have declined by as much as 48 percent since the late 1960s, according to the 2014 State of the Birds report released last week.
In Utah, Arizona and New Mexico, habitat loss and fragmentation due to development are the largest threats. These are also significant threats in the nation’s grasslands, where breeding birds like the eastern meadowlark and the bobolink have declined by 40 percent since 1968, with the steepest declines coming before 1990, when stakeholders started investing in grassland bird conservation.
And experts say it’s not just rare birds that are vanishing. The report includes a list of 33 common species in steep decline, losing ore than half their global populations over the past four decades — a clear warning sign that birds can undergo a massive population collapse with surprising rapidity. For example, passenger pigeon populations crashed from 2 to 3 billion birds to none in the wild in just 40 years. Continue reading

Feds consider changing manatee status from endangered to threatened
FRISCO — Gentle, slow-moving manatees are still facing serious threats from motorboats in Florida waterways and should continue be be listed as endangered, according to conservation advocates.
The U.S. Fish and Wildlife Service is considering down-listing manatees, but the move doesn’t make sense, considering that boat collisions are still the leading cause of death, as detailed in a new report issued by the Center for Biological Diversity.
The conservation group charges that federal and state officials have issued permits for thousands of new docks, boat ramps and piers without considering the cumulative effects on the marine mammals who favor the same near-shore waters used by Florida’s recreational boaters. Continue reading

Conservation works! Protective measures have helped restore blue whale populations in the eastern Pacific.
‘We think the California population has reached the capacity of what the system can take as far as blue whales’
FRISCO — Marine scientists say the population of California blue whales, living the eastern side of the Pacific Ocean from the equator up into the Gulf of Alaska, has rebounded to about 2,200 individuals, which may be near the historic pre-whaling level.
According to the new study, published the journal Marine Mammal Science, it’s the only population of blue whales known to have recovered from whaling after being nearly hunted to extinction.
“The recovery of California blue whales from whaling demonstrates the ability of blue whale populations to rebuild under careful management and conservation measures,” said Cole Monnahan, a University of Washington doctoral student in quantitative ecology and resource management and lead author of the paper.
