Without connectivity to other populations, grizzly bears are vulnerable to inbreeding and genetic depression
FRISCO — The task of recovering grizzly bears is far from done, according to wildlife advocates, who last week asked the U.S. Fish and Wildlife Service try and establish new populations of the apex predators in the Selway-Bitterroot ecosystem in central Idaho and western Montana.
As many as 50,000 grizzly bears roamed widely from the Pacific Ocean to the Great Plains in the pre-settlement era, but as pioneers moved in, bears were persecuted and their numbers and range drastically declined. Today, with the western United States inhabited by millions of Americans, there are only a few pockets of grizzly populations totaling about 1,400-1,700 wild grizzly bears. Of the 37 separate grizzly populations present in 1922, 31 were extirpated by 1975. Continue reading

73 condors now living in the wild in Utah and Arizona
FRISCO — In another small, encouraging sign that California condors may avoid extinction, biologists said last week that two-wild-fledged chicks have left their nests and taken flight in northern Arizona. A third condor chick — the first wild-fledged in Utah — did not survive.
California condors once soared widely from California to Florida and Western Canada to Northern Mexico but were nearly wiped out by the middle of the 20th century and listed as endangered in 1967. In 1982, only 23 condors survived world-wide, and in 1987, all remaining wild condors were placed into a captive breeding program. Continue reading

Should coyoyes be targeted in wildlife killing contests?
Advocacy groups seek ban in New Mexico
FRISCO — Emboldened by California’s recent ban on wildlife killing contests, wildlife advocates say they want lawmakers to enact similar restrictions in New Mexico, which holds more such events than any other state.
A coalition of 10 groups is calling on the governor and state legislature to ban contests that target coyotes, bobcats, foxes, prairie dogs and other animals, calling them immoral and biologically unsound. Continue reading

Lethal predator control leads to more livestock kills

FRISCO — Killing wolves to keep them from killing livestock is counterproductive and actually leads to more predation — up to a certain point — according to Washington State University researchers.
The scientists tested the idea that lethal control is an effective way of slowing predation and found the hypothesis lacking. Shooting and trapping lead to more dead sheep and cattle the following year, not fewer, they concluded in their study, published in the journal PLOS ONE. Continue reading

‘Many of the violations committed by Mr. Loncarich appear to be the result of greed, unlawfully killing and maiming wildlife to increase his profits’
FRISCO — A Colorado man and his Oregon helper — who claimed to be hunting guides — are facing stiff penalties after pleading guilty to violate the Lacey Act, a federal law prohibiting the interstate transportation and sale of any wildlife taken in an illegal manner. Continue reading

Trapping efforts suspended for now

FRISCO — Federal biologists say that, based on a genetic analysis of scat, they’re now 100 percent sure that the wolf-like animal spotted near the North Rim of the Grand Canyon is in fact a wild Rocky Mountain gray wolf.
The confirmation clarifies that this gray wolf is fully protected under the Endangered Species Act, the U.S. Fish and Wildlife Service announced. Biologists have been tracking the canid since early October and were able to collect scat samples in early November. Continue reading

New lawsuit challenges inadequate critical habitat designation
FRISCO — It’s been 15 years since Canada lynx were listed as a threatened species, and wildlife conservation groups are still battling the U.S. government in court over critical habitat designation for the rare, snow-loving cats.
In the latest legal move, the Sierra Club, Rocky Mountain Wild, and Alliance for the Wild Rockies went back to court this week, claiming that the U.S. Fish and Wildlife Service still hasn’t got it right. According to the lawsuit, the agency neglected to include numerous large areas of prime lynx habitat, corridors and occupied areas throughout five national forests in Montana and Idaho, as well as millions of acres in the Southern Rockies.
