Endangered Species

Grizzly Bear
A threatened subspecies of the grizzly or brown bear (Ursus arctos horribilis) is currently found in four national park units. $1,887,000 was expended on this species in 2010. Photo by NPS/M. Stouffer.

The National Park Service (NPS) works to sustain and recover over a thousand populations of federally listed threatened and endangered (T&E) species. At least one or more endangered species are found in 204 of the 394 National Park Service units. Our mission is to reduce the risk of extinction of plants and animals in the parks, and to restore species that have occurred in parks historically but have been lost due to human activities. The NPS seeks to be proactive in determining the status of rare species and cooperating with other agencies to conserve declining species to avoid listing under the Endangered Species Act (ESA). Every park provides yearly information on the status of current, historic, and extipated T&E species, the trend of the population, and the money spent on recovering and monitoring these species.

Parks in the Pacific West and the Southeast Regions have the greatest number of threatened and endangered species. This table displays parks with the most listed species. Not only do these areas of the country have great biologic diversity, but many of these areas have been significantly affected by invasive, non-native species and human development.
