Conservation of the Yellowstone Grizzly Bear

Conservation of the Yellowstone Grizzly Bear Abstract: We review literature relevant to the conservation of Yellowstone's grizzly hear population and appraise the bear's long‐term viability. We conclude that the population is isolated and vulnerable to epidemic perturbation and that the carrying capacity of the habitat is likely to shift downward under conditions of climate change. Viability analyses based on the assumption that future habitats will closely resemble those existing at present have limited applicability; more information is needed on the autecology of important bear foods and on the implications of landscape‐scale changes for bear population dynamics. Optimism over prospects of long‐term persistence for Yellowstone's grizzly bears does not seem to be warranted and management of this population should be conservative and not unduly swayed on short‐term positive trends. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Conservation Biology Wiley

Abstract

Abstract: We review literature relevant to the conservation of Yellowstone's grizzly hear population and appraise the bear's long‐term viability. We conclude that the population is isolated and vulnerable to epidemic perturbation and that the carrying capacity of the habitat is likely to shift downward under conditions of climate change. Viability analyses based on the assumption that future habitats will closely resemble those existing at present have limited applicability; more information is needed on the autecology of important bear foods and on the implications of landscape‐scale changes for bear population dynamics. Optimism over prospects of long‐term persistence for Yellowstone's grizzly bears does not seem to be warranted and management of this population should be conservative and not unduly swayed on short‐term positive trends.
