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

FRISCO — Loggerhead sea turtles may have a better chance of surviving — and even thriving — after federal agencies designated 685 miles of beaches along the Atlantic and Gulf of Mexico coastlines, as well as 300,000 square miles of ocean, as critical habitat. The decision came after more than five years of delays and court battles, as conservation groups sought protection for the turtles.
While the ocean habitat rule provides unprecedented habitat protection for loggerhead sea turtles, it only protects nearshore habitat for one mile off nesting beaches despite science showing the importance of habitat three miles from beaches for females and hatchlings. The rule also failed to identify critical habitat for the endangered North Pacific Ocean loggerhead, which is at risk due to Hawaii and California fisheries activities in areas overlapping with the loggerhead’s habitat.

Research suggests some species can develop or acquire an immunity to deadly fungal pathogens
By Summit Voice
FRISCO — Florida-based researchers say they may have some answers for the puzzling wave of amphibian deaths that’s been wiping out populations of some species. At least some frogs and snakes may be able to develop immunity to the deadly chytrid fungus that’s been implicated in the die-off, University of South Florida biologists said this week.
Their findings could be good news in general for biodiversity, as emerging fungal pathogens are seen as posing the greatest threat of any parastic pathogens, contributing to declines of amphibians, bats, corals, bees and snakes. Continue reading

Dwindling birds caught in a tangled web of science and politics
FRISCO — Just a couple of weeks after the U.S. Department of Agriculture announced $25 million in funding for greater sage-grouse conservation in California and Nevada, the federal government took another step in the long-running process to protect the dwindling birds by launching a new website.
Coordinated by three U.S. Fish and Wildlife Service information specialists, the new site emphasizes the collaborative nature of the conservation effort to protect the birds and their oft-overlooked sage-steppe habitat.
The scruffy badlands that stretch patchily between the Rockies and the Sierra Nevada may look empty, but there’s more than meets the eye, the USFWS explains on the new site’s intro page. Sage may dominate big slices of the landscape, but the ecosystem is threatened because not much of it is protected. Continue reading

Are wolverines in the U.S. doomed by global warming?
Leaked memo suggests USFWS is bowing to political pressure from western states
By Bob Berwyn
FRISCO — Federal officials apparently won’t let the best available science stop them from making yet another politically motivated endangered species decision.
This time, wolverines are at issue, as the U.S. Fish and Wildlife Service prepares to withdraw a proposal to list the rare mammal based on threats posed by global warming. The agency hasn’t officially announced its intention, but a leaked memo shows that USFWS Mountain-Prairie regional director Noreen Walsh wants to override the recommendations of her own scientists and withdraw the listing proposal. Continue reading

Scientists call for ‘zoning’ of coastal waters
By Summit Voice
FRISCO — Piecemeal planning and conservation efforts won’t be enough to preserve valuable ocean resources for future generations, a leading group of environmental and marine scientists said last week, calling on countries around the world to cooperate on zoning coastal waters in an approach that would mirror common land-use planning efforts.
Effective long-term conservation is crucial because about 20 percent of the world’s population — mostly in developing countries — lives within 60 miles of the coast. Growing populations and worsening climate change impacts ensure that pressures on tropical coastal waters will only grow, they warned. Continue reading

Healthy whale populations could buffer oceans from some global warming impacts
FRISCO — Whales may play a much bigger role in ocean ecosystems than previously thought, according to a University of Vermont researcher who studied how the great cetaceans recycle and move nutrients from one region to another.
“For a long time, whales have been considered too rare to make much of a difference in the oceans,” notes University of Vermont conservation biologist Joe Roman.
That was a mistake, he said, explaining how his research shows that whales have a powerful and positive influence on the function of oceans, global carbon storage, and the health of commercial fisheries. Continue reading

Ocean advocates say warming ocean drives sea turtles into floating gillnets
FRISCO — Along with the potential for affecting weather over North America, the emerging El Niño conditions on the Pacific Ocean could pose a threat to endangered loggerhead sea turtles, conservation advocates say, calling on federal fisheries managers to implement legally required restrictions on gillnet fishing to protect the turtles.
When ocean waters in the eastern Pacific get warmer, the loggerheads tend to move into commercial fishing grounds, where they often die after getting tangled up in nets. When El Niño is occurring or forecasted, the Pacific Loggerhead Conservation Area (California ocean waters east of 120 degrees latitude) is, by law, closed to drift gillnet fishing during June, July and August.

Federal protections needed to protect dwindling Gunnison sage-grouse
FRISCO — A new report by conservation biologists suggests that local and state-based measures to protect Gunnison sage-grouse won’t prevent the species from sliding toward extinction.
With only about 5,000 remaining birds, the population is already at a high risk, and only strict federal conservation measures under the Endangered Species Act will help, according to Megan Mueller, a senior conservation biologist with Rocky Mountain Wild.
The once-abundant species has dwindled dramatically as its habitat has been fragmented by energy and community development, as well as over-grazing. Continue reading
