(July 28, 2016) – When the U.S. Fish and Wildlife Service (USFWS) declared in 2011 that the eastern cougar was extinct, the irony reverberated throughout the wildlife-protection movement. In a letter to USFWS this week, conservation organizations commented that the problem with such a decision is that no scientific evidence exists that the cougars which once ranged the East are different than other cougars throughout North America.
“The USFWS cannot declare extinct a cougar subspecies our best science now understands never existed,” says Cougar Rewilding Foundation president, Christopher Spatz. “The USFWS needs to develop a federal recovery plan for the entire historic range of the North American cougar including the eastern U.S.”
Currently, the puma species native to the western hemisphere taxonomically is named Puma concolor (also known as cougar, mountain lion, and panther). Listed as an endangered species in 1973, Puma concolor cougar, the eastern cougar, was just one of 32 subspecies described in 1946. However, genetic research in the 1990s determined there were just six subspecies, including the one that is widely distributed across North America, Puma concolor cougar.
The 2011 USFWS review acknowledges that the 1946 taxonomy of the eastern cougar is flawed. Modern research cannot distinguish between the thousands of cougars living throughout the western U.S. and the rare historic specimens tested east of the Mississippi River. Cougar biologists now generally agree there is a single North American subspecies.
“This is a simple case of a broadly-dispersed North American subspecies moving to recover its historic range east of the prairie states,” said Lynn Cullens of the Mountain Lion Foundation. “The big cats face no fewer threats than when they were originally listed. Federal action should include, not remove, protections for animals seeking territory within the former range.”
The main point made by cougar advocates is that cougars need federal protection under the Endangered Species Act (ESA) across the entire range from which they were exterminated. Recolonization has been attempted by cougars dispersing from prairie states into the Midwest for a generation, with rare evidence of the cats roaming as far afield as the Michigan Upper Peninsula, Kentucky and even Connecticut. “The Midwest has been a cougar graveyard for 25 years,” said Spatz, “Females and wild kittens have not been documented east of the Missouri River.”
Adding to the complexity of the puma recovery effort is the fact that the endangered panther of Florida – currently listed under the ESA as a subspecies – shares the primary genetic makeup of the rest of the U.S. population. “As the lone surviving cougar population in the East,” said Cullens, “the panther’s federal recovery plan, including reintroductions, is critical to recovery across the southeastern U.S., and the panther should remain fully protected by future USFWS decisions.”
A recent scientific paper, “An Ecosystem Service of Cougars,” gave a strong boost to the argument for a new federal recovery plan for cougars when it pointed out that deer in the U.S. (the cat’s main prey) cause 1.2 million deer-vehicle collisions annually, incurring $1.66 billion in damages, 29,000 injuries, and over 200 deaths. “Pumas are one of the most important ecosystem regulators we have,” notes Greg Costello of Wildlands Network. “When people see the economic and safety value of big carnivores doing their natural work, we’ll all benefit.”
“We can’t rely on a shooting gallery of state laws that encourage everything from unenforced protections to ‘kill on sight’ to no policy at all,” notes Cullens. “State laws are real obstacles, sure as bullets, and cougars don’t see borders.”
The groups believe that the federal law and spirit that restored bald eagles and peregrine falcons to the East should apply to every cougar on a journey to reclaim its historic range.
Wildlands Network envisions a world where nature is unbroken, and where humans co-exist in harmony with the land and its wild inhabitants. Our mission is to reconnect, restore, and rewild North America so life in all its diversity can thrive.
