Proposed critical habitat designations could help protect dwindling loggerhead sea turtles in the Gulf of Mexico.
Findings may help protect dwindling population
FRISCO — The beleaguered population of loggerhead sea turtles in the northern Gulf of Mexico feeds in areas affected by the 2010 Deepwater Horizon spill and where they are threatened by other human activities.
The feeding areas for 10 turtles overlapped with an area that experienced surface oiling during the 2010 Deepwater Horizon oil spill. These sites, and others, also overlapped with areas trawled by commercial fishing operations and used for oil and gas extraction, U.S. Geological Survey scientists said after tracking 59 nesting females. That could be about 15 percent of the entire breeding females in the Northern Gulf of Mexico—a small and declining subpopulation of loggerheads that is federally classified as threatened.

National Park Service launches 3-year study on possible restoration
FRISCO — In a big move for grizzlies and wild ecosystems, the National Park Service this week launched a three-year environmental study to evaluate to possibility of restoring the apex predators to the North Cascades.
“This is the first stage of a multi-step process to help inform decisions about grizzly bear restoration in the North Cascades ecosystem,” said National Park Service Director Jonathan B. Jarvis. “The National Park Service and our partners in this effort haven’t made any decisions about the bear’s restoration at this time as federal law requires us to look at a range of options, including not restoring grizzlies to the area.” Continue reading

Feds map critical habitat for yellow-billed cuckoo
Will yellow-billed cuckoos make a comeback in Colorado?
By Summit Voice
FRISCO — The long endangered species odyssey of the yellow-billed cuckoo may be one step closer to resolution, as federal wildlife officials this week proposed designating more than half a million acres of critical habitat for the birds, sometimes known as rain crows for their habit of singing before a storm.
The bird was once common along most rivers and streams in the West, but the decline of the species, eyed for protection since 1986, shows how much human activities have degraded riparian riverside habitat. Yellow-billed cuckoos are neotropical migrants that winter in South America and nest along rivers and streams in western North America. Continue reading

U.S. Fish and Wildlife Service will face new lawsuit over failure to give the species endangered species status
By Bob Berwyn
FRISCO — In a decision that’s certain to trigger a new round of lawsuits, the U.S. Fish and Wildlife Service announced today that it won’t put wolverines on the Endangered Species List.
The decision was made by the agency’s regional directors from the areas where wolverines are native. In a release, the U.S. Fish and Wildlife Service director Dan Ashe contradicted all the best available science from his agency’s own biologists, claiming that there’s too much uncertainty about global warming impacts to list wolverines.

How do pesticides affect wildlife? We’ll know more after a court-ordered environmental study.
Legal settlement requires agency to analyze effects of 5 common pesticides
FRISCO — Under legal pressure from conservation advocates, the EPA last week agreed to take a hard look at how five commonly used pesticides affect endangered animals across the U.S.
One of the pesticides is carbaryl, commonly used in massive quantities in Colorado to try and protect trees from bark beetles. The other pesticides to be reviewed are chlorpyrifos, diazinon, malathion and methomyl. All have all been found to be toxic to wildlife and may pose a health risk to humans. Continue reading

FRISCO — Rare and beleaguered Mexican gray wolves may get a little more room to roam in the Southwest, as the U.S. Fish and Wildlife Service proposes changes to a recovery plan from the species, including new releases of captive-bred wolves to bolster wild populations.
The new releases could happen in new areas of New Mexico and parts of Arizona where there are no wolf packs yet, and the federal agency’s proposed changes would also allow wolves to roam from the Mexican border to Interstate 40, a much broader region than currently permitted.
Only 83 Mexican wolves live in the wilds of the Southwest, including just five breeding pairs. Scientists have shown that inbreeding caused by a lack of wolf releases to the wild, coupled with too many killings and removals of wolves, is causing smaller litter sizes and lower pup-survival rates in the wild population. Expanding wolf releases to New Mexico’s Gila National Forest, in particular, would enable managers to diversify the population through new releases and diminish inbreeding. Continue reading

Can the endangered birds recover from the brink of extinction?
FRISCO — California condors have been hovering on the brink of extinction for decades. But the majestic birds may be on the verge of making a comeback in southern Utah, National Park Service biologists said last week, announcing the first-ever birth of a condor chick in Zion National Park.
Without revealing the exact location to the public, biologists had been monitoring a rock cavity in a remote corner of the park for several weeks where they observed the nesting pair. Finally, on June 25, the condor chick made its first appearance at the edge of the nest. Continue reading
