EPA to study pesticide impacts to endangered species

f

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

Staff Report

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

Biodiversity: Some progress for Mexican gray wolves?

Feds propose updates to management of Southwest wolves

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?

Staff Report

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

Oceans: Feds finalize critical habitat designation for threatened loggerhead sea turtles

Staff Report

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.

Can amphibians bounce back from the brink?

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

Feds launch greater sage-grouse website

Dwindling birds caught in a tangled web of science and politics

Staff Report

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

Feds to backpedal on wolverine protection

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.
