Projected Climate Change Impacts to Grizzly Bear (Ursus arctos) Carrying Capacity in the North Cascades Ecosystem

Habitat for grizzly bears in the North Cascades Ecosystem (NCE) was evaluated in the early 1990’s. Although the NCE was home to only a small number of grizzly bears, the evaluation determined the NCE was capable of providing habitat of sufficient quality and quantity to support a population of 200-400 bears. Since that time, there has been an advancement in the understanding of grizzly bear habitat use, population ecology, and methods to estimate the potential carrying capacity of wildlife populations within ecosystems.
