We are committed to ensuring that grizzly populations are healthy and large enough to be viable in the long-term, and that strong habitat protections are in place prior to removing the grizzly from the endangered species list. In Wyoming, we are working to protect the grizzly of the Greater Yellowstone Ecosystem from premature delisting.
