As was the case for other large carnivores in the lower 48 United States, by the 1960s grizzly bears were nearly extinct. This species had dropped to less than 2 percent of its former range south of Canada and occurred in six small, discrete populations, totaling 800-1,000 individuals.

The lynx is one of the most at-risk carnivores in the United States. South of the US-Canada border, this elusive species’ population may be as low as a few hundred individuals.

It vectors millions of people and their vehicles through this iconic landscape, creating a lethal corridor for wildlife.
