Eastern cougars that once roamed North America from Canada to South Carolina are extinct and no longer warrant federal Endangered Species Act protections, US wildlife managers have said.
The proposal to remove so-called eastern cougars from the list of endangered and threatened species comes nearly 80 years after the last of those mountain lions was believed to have been trapped and killed in New England, according to the US Fish and Wildlife Service.
Cougars, also known as panthers and pumas, were once the most widely distributed land mammal in the western hemisphere, but extermination campaigns have seen the large wild cats eliminated from roughly two-thirds of their original range, federal wildlife biologists said.
The Fish and Wildlife Service in 2011 opened an extensive review of the status of eastern cougars, cousins to mountain lions that still roam western US states and the imperiled Florida panthers.
The agency said on Tuesday the four-year review, which included information from 21 states and eastern Canadian provinces and hundreds of reports of sightings dating as far back as 1900, showed cougars are seen every so often in the US east, but they are likely Florida panthers or mountain lions that have wandered from the western United States, or which have been released or escaped from captivity.
Eastern cougars were declared endangered in 1973, even though the last known records were tied to one killed by a hunter in Maine in 1938 and another in New Brunswick, Canada, in 1932.
The agency is accepting comment on the delisting plan until 17 August.
