State decides on endangered species status for wolves even as feds proceed with national de-listing push

FRISCO — When wolves start to reclaim their historic territories in the wilds of California, they’ll be protected under state law. The California Fish and Game Commission voted last week to protect gray wolves under the state’s Endangered Species Act after being petitioned by the Center for Biological Diversity.
The decision came just a few days after biologists documented the presence of two wolf pups in the Oregon portion of the Rogue River-Siskiyou National Forest that straddles the California-Oregon border. The pups, which are likely to be part of a litter of four to six pups, are the offspring of the wolf known as OR-7, which has made California part of his range for the past four years.

FRISCO — Conservation biologists in the San Francisco bay area say they’re facing a conundrum, as they try to remove an invasive salt marsh grass while recovering an endangered bird that has come to rely on the non-native plant.
In a study published last month in the journal Science, researchers at the University of California, Davis said that an all-out push to eradicate the marsh cordgrass could hamper efforts to recover the clapper rail, a bird on the brink because of urban development and loss of wetlands.
Their results showed that, rather than moving as fast as possible with eradication and restoration, the best approach is to slow down the eradication of the invasive species until restoration or natural recovery of the system provides appropriate habitat for the endangered species.
Scientists in the southwestern U.S. have faced similar issues as they try to remove invasive tamarisk, which has come to provide habitat for rare southwestern willow flycatchers. Continue reading

While Republican lawmakers play election-year politics, sage grouse are going extinct
Western Republicans looking to strip protections for dwindling species
By Bob Berwyn
FRISCO — A group of right wing western lawmakers want to kill federal protections for dwindling sage grouse for at least 10 years with a proposed law that would specifically prevent the iconic birds from being listed as threatened or endangered under federal law.
Using the twisted Orwellian doublespeak that’s become common in anti-environmental GOP circles, the proposed bill is called the Sage Grouse Protection and Conservation Act — which would strip federal biologists of their authority to make an accurate, science-based determination about the status of the birds. Continue reading

Feds to consider expanded habitat protections for endangered resident population of killer whales
By Summit Voice
FRISCO — Federal biologists will take another look at an endangered population of killer whales off the West Coast to determine whether they need more critical habitat.
The southern resident population of the marine mammals, based in Puget Sound, range along the Pacific Coast. A critical habitat expansion would protect winter foraging range off the coasts of Washington, Oregon and California, according to the Center for Biological Diversity, which spurred the review with a formal petition.
“Despite nearly a decade of federal protection, the Puget Sound’s orca population remains perilously small, hovering around only 80 animals,” said Sarah Uhlemann, senior attorney at the Center for Biological Diversity. “This proposal is an important step toward recovery and will help the whales stave off extinction.” Continue reading

FRISCO — The slowly recovering population of Mexican gray wolves in the Southwest may face even more pressure in coming years, as state officials in Arizona seek to codify a new wolf management plan that could restrict recovery efforts. Continue reading

New study suggests that spent lead ammunition could make it impossible to recover the species
FRISCO — Accidental ingestion of spent lead ammunition is killing endangered California condors at a rate that may prevent the birds from establishing self-sustaining populations.
The condors were among the first animals to be protected under the Endangered Species Act. By 1966, the population had dropped to just a handful of birds, but a massive collaborative conservation effort helped the population grow to more than 400 individuals.
But those gains may be at risk, according to San Diego Zoo conservation biologists.
“After reviewing nearly 20 years of our mortality data on the free-ranging birds, it became clear that lead poisoning is the primary problem for the birds in the wild,” said Bruce Rideout, director of the wildlife disease laboratories for San Diego Zoo Global.
“And this is not just a problem for California condors. We can view them as an indicator species, warning us about the hazards of widespread lead contamination in the environment.” said Bruce Rideout, director of the wildlife disease laboratories for San Diego Zoo Global.
The recent study of lead impacts was done with researchers from the Wildlife Health Center at the School of Veterinary Medicine, University of California at Davis. The findings are published in the January edition of the journal EcoHealth.

FRISCO — A federal judge last week rejected claims by developers that a 2011 agreement between environmental groups and the federal government will hurt the industry.
At issue is a groundbreaking deal covering more than 700 species that could someday be listed as threatened or endangered. Under the agreement, the U.S. Fish and Wildlife Service said it will make listing decisions on all the species by 2018, and so far, 138 species have been protected or formally proposed for protection.

Why are so many Republicans opposed to efforts to protect and restore endangered and threatened species?
Not much substance, a lot of political smoke …
FRISCO — The Republican anti-environment cadre in the House is once again taking aim at the Endangered Species Act by introducing legislation that would make it even harder for federal agencies to protect animals and plants that are at risk of going extinct.
Two of the bills, H.R. 4316 and H.R. 4318, would limit the ability of citizens to challenge government decisions in court. The Republican measures are also ostensibly aimed at reducing the government’s legal costs associated with responding to endangered species lawsuits, but conservation advocates said that is an ideological red herring. Government data shows that the Department of Interior has spent far more money responding to frivolous demands for documents than on settling lawsuits.

Wolves numbers are slowly increasing in the Southwest.
Hopeful signs for recovery effort, but challenges remain
By Bob Berwyn
FRISCO — Against a backdrop of political and legal battles over the status of wolves, Mexican gray wolf numbers have increased the fourth year in a row, with 83 wolves now living in the wilds of New Mexico and Arizona.
That’s up 10 percent from last year and almost 100 percent from four years ago, according to the annual tally from the U.S. Fish and Wildlife Service. The number of breeding pairs also increased from three to five. Continue reading

Nearly 1,200 square miles of territory protected for recovery of native cats
By Summit Voice
FRISCO — Nearly 17 years after federal biologists first listed jaguars under the Endangered Species Act, the wild cats may now have a protected area to roam in the wilds of the Southwest.
The U.S. Fish and Wildlife Service this week designated about 1,200 square miles of rugged desert, mountain and forest lands in southern Arizona and New Mexico as critical habitat for jaguars — but only after a sustained legal push by the Center for Biological Diversity.
The federal wildlife agency initially resisted mapping out protected areas, claiming that the cats are too rare for habitat protection. Wildlife advocates challenged the agency’s position and a federal court rejected the government’s argument, leading to this week’s critical habitat listing notice in the Federal Register. The USFWS is also working on a jaguar recovery plan for the area. Continue reading
