FRISCO — Panther deaths in Florida climbed to a record level in 2014, as the wild cats continue to succumb to collisions with vehicles on highways in southwest Florida.
In all, 30 panther deaths were reported by the Florida Fish and Wildlife Conservation Commission this year, topping the previous record of 27 deaths tallied in 2012. More than half of this year’s deaths were the result of collisions with vehicles.
Panther mortality this year could represent as much as one-fourth of the entire population, which the Florida Fish & Wildlife Conservation Commission estimates at between 100 and 180 animals. The reason for this wide variation is that the number of cats monitored through radio collars has steadily declined. Continue reading

‘Mistaken identity’ shooting fits disturbing pattern of accidental kills, wildlife advocates say
Arizona Game and Fish Department
By Summit Voice
FRISCO — A coyote hunter shot and killed a federally protected gray wolf in southwestern Utah Sunday, probably the same wolf that had been spotted repeatedly around the North Rim of the Grand Canyon in recent weeks.
According to the Utah Division of Wildlife Resources, the wolf was radio-collared near Cody, Wyoming a year ago. The state agency said the hunter voluntarily reported the kill when he noticed the radio-collar. Continue reading

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

Agreement with Native Americans could bolster populations of listed fish
FRISCO — Federal biologists are teaming up with Native Americans in eastern California to try and recover the endangered Owens pupfish under a safe harbor agreement that may include translocation of wild Owens pupfish to tribal lands, maintaining habitat, providing a source population for future reintroductions, and public education and outreach. 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

Study shows livestock grazing a key factor in greater sage-grouse decline
FRISCO — A new study by sage grouse scientists confirms that the height of grass cover in nesting habitat is a key factor in determining greater sage grouse nest success.
The findings suggest that better grazing management is needed to protect the threatened birds. Cattle eat native vegetation that sage grouse require for hiding their nests from predators. Continue reading

Refuge managers seek to balance protection of marine mammals with demand for public access at Three Sisters Springs
FRISCO — The U.S. Fish and Wildlife Service says a careful management plan at a freshwater spring in Florida can help protect manatees and ensure public access to the popular Three Sisters Springs recreation area.
The agency this week started taking input on a draft environmental assessment for management actions to protect manatees and still allow public access at Three Sisters Springs during the winter season. Continue reading
