Historical records indicate grizzly bears (Ursus arctos) once occurred throughout the North Cascades of Washington (Almack et al. 1993, Gaines et al. 2000) and into British Columbia, but the population has since declined due to intensive historical trapping, hunting, predator control, and habitat loss.
