What's at Stake

Grizzly bears in the lower-48 states were reduced to 1% of their historic range and 1–2% of their historic numbers due to persecution and habitat destruction associated with the march of human development.

Case Overview

Grizzly bears in the lower-48 states were reduced to one percent of their historic range and one to two percent of their historic numbers due to persecution and habitat destruction associated with the march of human development. One of their last remaining strongholds exists in Yellowstone National Park and surrounding public lands.

In recent years, the federal government has attempted to remove Endangered Species Act protection from Yellowstone-area grizzly bears. Earthjustice stepped in to oppose that effort as part of a broader campaign to protect grizzlies from excessive killing and habitat destruction.

In November 2011, a federal appeals court upheld a lower-court ruling that reinstated Endangered Species Act protections for Yellowstone’s iconic grizzly bear population. The court agreed with Greater Yellowstone Coalition, represented by Earthjustice, that the government’s irrational response to the loss of a key food source due to climate change requires continued federal ESA protections for Yellowstone’s grizzlies.

One month later, a federal appeals court provided additional protections to grizzly bears and other Yellowstone wildlife by ruling that the Forest Service must protect a wilderness study area adjoining the northern boundary of Yellowstone National Park from damage and disruption caused by snowmobiles and dirt bikes. The area contains important habitat for grizzly bears, wolverines, and lynx, but the Forest Service authorized escalating levels of snowmobile and motorcycle use in the area. In response, conservation groups, represented by Earthjustice, filed a lawsuit to enforce legal protections for the area under the 1977 Montana Wilderness Study Act.

Court Gives Grizzlies Something To Sleep On

In an ecosystem where all life is interrelated and connected, the decline of one life form can precipitate the decline of another. In other words, as the whitebark pine seeds go, so go the Yellowstone grizzlies. In November 2011, the 9th Circuit Court of Appeals upheld a ruling that reinstated Endangered Species Act protections for Yellowstone’s iconic grizzly bear population.
