Grizzly Bear Defenders of Wildlife

Grizzly bears were once numerous, ranging across North America from California to the Great Plains, and from Mexico all the way up into Alaska. As with many species, westward expansion, human transformation of the landscape, and fear led to near-eradication of grizzly bears in the continental United States. When the grizzly bear was listed under the Endangered Species Act (ESA) in 1975, the grizzly bear population in the lower 48 states was down to less than 1000 bears. Grizzly bears still occupy less than 2% of their former range in the lower 48, in 5 of 6 grizzly bear recovery areas.
