Crow Indian Tribe v. United States of America

Why We Fight:

People who carry the burden of living amongst dangerous predators like the grizzly bear must be heard when those from elsewhere ignore their impact on human beings.


Although the grizzly bear population in western Wyoming is recovered fully and can be managed by State wildlife officials consistent with the needs of its human neighbors, environmental groups demand that the grizzly bear remains on the Endangered Species Act list.

Legal Question:

Whether the federal government may both designate a distinct population of a species and remove that population from the Endangered Species Act list?

U.S. District Court for the District of Montana, Missoula Division
A decision by the federal district court on MSLF's motion to intervene for its clients.

In June of 2017, the U.S. Fish and Wildlife Service (FWS) proposed to designate the grizzly bear population in the so-called Greater Yellowstone Ecosystem as a “distinct population segment,” meaning it is a “discrete” but “significant” part of the national grizzly bear population.  In addition, the agency found, after extensive research and careful monitoring, that the region’s grizzly bear population exceeded the minimum population goal set by scientists in 2013, was recovered fully, and was no longer in danger of becoming extinct.  (There is only a one percent chance the grizzly bear could become extinct within the next 100 years.)  Therefore, the FWS removed the region’s grizzly bear population from any Endangered Species Act listing, which allows Wyoming wildlife officials to manage grizzly bear populations in the Equality State. 

Starting in the summer of 2017, various environmental groups and American Indian tribes sued to reverse the agency’s action, including a lawsuit filed in Montana.  On February 28, 2018, MSLF filed a motion to intervene on behalf of its clients.
