Federal researchers declare eastern cougar extinct

ALLENTOWN, Pa. – The "ghost cat" is just that.

The U.S. Fish and Wildlife Service on Wednesday declared the eastern cougar to be extinct, confirming a widely held belief among wildlife biologists that native populations of the big cat were wiped out by man a century ago.

After a lengthy review, federal officials concluded there are no breeding populations of cougars — also known as pumas, panthers, mountain lions and catamounts — in the eastern United States. Researchers believe the eastern cougar subspecies has probably been extinct since the 1930s.

Wednesday's declaration paves the way for the eastern cougar to be removed from the endangered species list, where it was placed in 1973. The agency's decision to declare the eastern cougar extinct does not affect the status of the Florida panther, another endangered wildcat.

Some hunters and outdoors enthusiasts have long insisted there's a small breeding population of eastern cougars, saying the secretive cats have simply eluded detection — hence the "ghost cat" moniker. The wildlife service said Wednesday it confirmed 108 sightings between 1900 and 2010, but that these animals either escaped or were released from captivity, or migrated from western states to the Midwest.

"The Fish and Wildlife Service fully believes that some people have seen cougars, and that was an important part of the review that we did," said Mark McCollough, an endangered species biologist who led the agency's eastern cougar study. "We went on to evaluate where these animals would be coming from."

A breeding population of eastern cougars would almost certainly have left evidence of its existence, he said. Cats would have been hit by cars or caught in traps, left tracks in the snow or turned up on any of the hundreds of thousands of trail cameras that dot Eastern forests.

But researchers have come up empty.

The private Eastern Cougar Foundation, for example, spent a decade looking for evidence. Finding none, it changed its name to the Cougar Rewilding Foundation last year and shifted its focus from confirming sightings to advocating for the restoration of the big cat to its pre-colonial habitat.

"We would have loved nothing more than for there to be a remnant wild population of cougars on the East Coast," said Christopher Spatz, the foundation's president. "We're not seeing (evidence) because they're not here."

Others maintain that wild cougars still prowl east of the Mississippi.

Ray Sedorchuk, 45, an avid hunter and outdoorsman, said he got an excellent look at a cougar last June in rural Bradford County, in northern Pennsylvania. He was in his truck when a reddish-brown animal with a long tail crossed the road. He said he jammed on the brakes, and the cougar stopped in its tracks.

"I could see the body, the tail and the head, the entire animal, perfectly. It's not a bobcat, it's not a housecat, it's a cougar," he said. "It's a sleek animal. It ran low to the ground and stealth-like. It moved with elegance."

Sedorchuk, a freelance writer who spends copious amounts of time in the woods, said he'd always been skeptical of the eastern cougar's existence, even as two of his friends insisted to him that they had seen them in the wild.

And now?

"I believe that they're here, without even thinking twice about it," he said. "I believe there aren't that many, but there are enough where they can get together and breed."

Once widely dispersed throughout the eastern United States, the mountain lion was all but wiped out by the turn of the last century. Cougars were killed in vast numbers, and states even held bounties. A nearly catastrophic decline in white-tailed deer — the main prey of mountain lions — also contributed to the species' extirpation.

McCollough said the last wild cougar was believed to have been killed in Maine in 1938.

The wildlife service treated the eastern cougar as a distinct subspecies, even though some biologists now believe it is genetically the same as its western brethren, which is increasing in number and extending its range. Some experts believe that mountain lions will eventually make their way back East.

The loss of a top-level predator like the cougar has had ecological consequences, including an explosion in the deer population and a corresponding decline in the health of Eastern forests.

"Our ecosystems are collapsing up and down the East Coast, and they're collapsing because we have too many white-tailed deer," said Spatz. "Our forests are not being permitted to regenerate."

Cougars and wolves, he said, would thin the deer herd through direct predation while also acting as "natural shepherds," forcing deer to become more vigilant and "stop browsing like cattle."

Spatz's group would like the federal government to reintroduce cougars and wolves to the eastern United States, though he acknowledged any such plan would come up against fierce resistance.

The wildlife service said Wednesday it has no authority under the Endangered Species Act to reintroduce the mountain lion to the East.

Dunes Sagebrush Lizard Proposed for Endangered Listing in ESA

More than eight years after the Center for Biological Diversity first petitioned to earn protection for the imperiled dunes sagebrush lizard, this week the U.S. Fish and Wildlife Service finally proposed to declare the species endangered. The light-brown, yellow-eyed lizard -- about the length of a human hand from nose to tail -- dwells in the dunes of New Mexico and Texas, where it buries itself in cool, white sand in the shade of shinnery oaks to avoid predators and regulate its body temperature. Unfortunately, oil and gas development and herbicide spraying are fast destroying the habitat of this rare reptile -- which already has the second-smallest range of any North American lizard. The species was first found to warrant federal protection in 2004 following our 2002 petition, but instead of adding it to the endangered species list, the feds made it a "candidate" for Endangered Species Act status -- putting off real protection indefinitely.


"The unique dunes sagebrush lizard may finally be receiving the help it needs to survive," said Noah Greenwald, endangered species director at the Center. "Unfortunately, during eight years of delay, the lizard lost more of its habitat to oil and gas development, putting it at greater risk of extinction and making recovery harder."

U.S. proposes calling two types of seals threatened

By Yereth Rosen

ANCHORAGE, Alaska

ANCHORAGE, Alaska (Reuters) - Two types of seals should be granted protection under the Endangered Species Act because the Arctic ice and snow they depend on is vanishing due to climate change, a U.S. government agency said on Friday.

The National Oceanic and Atmospheric Administration formally proposed threatened listings for ringed seals and bearded seals.

Both types of seals need floating sea ice, especially in late spring and early summer when they are caring for newborn pups. Ringed seals also need deep snowdrifts because pups are born in snow caves burrowed by mother seals, NOAA said.


The late-winter and springtime rains and early melts that are occurring with greater frequency in the Arctic limit snow cave formation and expose the newborns to dangers, NOAA officials said.

"The ringed and bearded seals are especially dependent on sea ice and snow cover," NOAA spokeswoman Julie Speegle said.

The populations proposed for listing are concentrated in the Arctic and North Pacific waters off Alaska, where summer sea ice has been diminishing over the past decades, but range as far east as the north Atlantic and as far west as Siberia.

All the populations proposed for listing are in danger of going extinct in the foreseeable future, NOAA said.

Arctic sea ice cover this year dropped to the third lowest level since satellite records began in 1979, according to the National Snow and Ice Data Center in Boulder, Colorado.

SPECIES IN TROUBLE


If NOAA follows through with a formal listing, the seals will be the first Alaska animals granted Endangered Species Act protections because of climate change since polar bears were listed as threatened in 2008.

Speegle said NOAA's proposal was evidence that warming Arctic conditions were bad for more than just polar bears, adding, "I think it indicates that climate change is having an impact on the habitat here for a wide variety of species."

"We're seeing that all species in the Arctic are in trouble," said Rebecca Noblin, Alaska director for the Center for Biological Diversity, an environmental group that sued to secure listing for the seals, polar bears and other animals.

The proposal, which came on a deadline established in a court settlement between the Center for Biological Diversity and NOAA, was an important milestone, Noblin said. She noted the U.S. Fish and Wildlife Service listed the polar bear.


"We're hoping that NOAA will make more of an effort to address the real threat to the seal species, which is greenhouse gas emissions," she said.

Following a 60-day public comment period on NOAA's listing proposal, the agency has a year to make a final determination.

There are other species dwelling in icy waters that federal scientists have determined are at risk.


The Fish and Wildlife Service is considering a proposal to list the Pacific walrus as threatened and faces a January 31 deadline for a decision. NOAA in October listed two populations of ice-dwelling spotted seals as threatened, although both are outside the United States.
