Threatened and Endangered Species
The effort to halt human-caused extinctions in the United States is guided by the Endangered Species Act of 1973. This Act defines an "endangered species" as any plant or animal species that is in danger of extinction throughout all or a part of its range. A "threatened species" is one that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.Endangered Species & The National Parks
The National Park Service is unique among federal agencies in that its prime mission, in natural areas of national parks, is to maintain nature in all its diversity undisturbed by human activity. This especially benefits many endangered species, which are particularly vulnerable to human influences.
The Missouri National Recreational River (MNRR) is home to three threatened and endangered species:
Working Together - Restoring The River
Research and management of threatened and endangered species in national parks, including the MNRR, are usually cooperative activities. The U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service have major roles in the work on these three species.
Recently, several agencies and organizations, led by the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service, have begun a decades-long process to restore the river. This restoration does not mean that Lewis and Clark would recognize the "Big Muddy," but rather to restore some of the river ecosystem's natural form and function. This restoration will necessarily help the recovery of the threatened and endangered species living in and along the river.
