Keystone Species

Keystone Species

A keystone species is a plant or animal that plays a unique and crucial role in the way a particular ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether.  Prairie dogs, wolves, coyotes, and birds of prey are a few of the more well-known keystone species. The impact on ecosystems as a result of the loss of these species can be seen throughout the United States.

            Our Keystone Species’ Work:


  • Wild Horses: Friends of Animals announces a bold, new initiative to protect America’s Wild Horses.  June 6, 2013-After decades of torment, round-ups, and killing at the hands of the Bureau of Land Management, Friends of Animals (“FoA”) and The Cloud Foundation have petitioned the U.S. Fish and Wildlife Service to list North American wild horses on all U.S. federal public lands endangered under the Endangered Species Act. Wild horses on U.S. federal public lands in North America warrant ESA protections as a distinct population segment of horses, the continued existence of which is imperiled.


  • The Gray Wolf: Friends of Animals believes that the Gray wolf deserves a place on the endangered species list and is working against the government’s plan to delist them.

October 16, 2013- Friends of Animals will be co-sponsoring a Citizens’ Wolf Hearning in Denver, Colorado where citizens can voice opposition against the FWS plan to remove Gray wolves from the endangered species list.
