The Ecological Services Program works formally and informally with a large variety of groups and individuals to further species conservation. Partnerships for protecting and recovering endangered and threatened species have been established between the Ecological Services Program and other U.S. Fish & Wildlife Service programs, other federal agencies, state governments, private landowners, non-governmental organizations (NGOs), and American Indian tribes.

They were first described by western scientists in 1958 based on several skulls. This species is the smallest known cetacean. These porpoises reach about four to five feet in length and weigh 65 to 120 pounds. Females are generally slightly larger than males.

Scientific Name: Canis lupus baileyi
Overview: The Mexican wolf is the rarest subspecies of gray wolf in North America. Once common throughout portions of the southwestern United States, the Mexican wolf was all but eliminated from the wild by the 1970s. In 1977, the U.S. Fish and Wildlife Service initiated efforts to conserve the species. In 1998, Mexican wolves were released to the wild for the first time in the Blue Range Wolf Recovery Area. Missing from the landscape for more than 30 years, the howl of the Mexican wolf can once again be heard in the mountains of the southwestern U.S.

Scientific Name: Ursus arctos horribilis
Overview: When Lewis and Clark explored the West in the early 1800s an estimated 50,000 grizzly bears roamed between the Pacific Ocean and the Great Plains, across vast stretches of open and unpopulated land. But when pioneers moved in, bears were persecuted and their numbers and range drastically declined. As European settlement expanded over the next hundred years , towns and cities sprung up, and habitat for these large omnivores – along with their numbers – shrunk drastically. Today, with the western United States inhabited by millions of Americans, only a few small corners of grizzly country remains, supporting about 1,400 to 1,700 wild grizzly bears. Of the 37 separate grizzly populations present in 1922, 31 were extirpated by 1975.
