Abstract
Populations of all 3 of North America's bear species have increased during the past 50 years, attributable to reduced persecution and improved management. Some actions consistent with the North American Model of Wildlife Conservation can explain these population increases, although conservation practices vary substantially among jurisdictions and species. Most management and conservation of North America's bear species is by state, provincial, or territorial agencies. However, federal engagement has occurred for grizzly bears (Ursus arctos), polar bears (U. maritimus), and some black bear (U. americanus) populations. Harvest has been the primary tool that agencies have used to manage bear populations. Increased focus on managing habitats and mitigating human–bear conflicts will help to ensure the long-term success of bear management in North America.
期刊介绍：
The Journal of Wildlife Management publishes manuscripts containing information from original research that contributes to basic wildlife science. Suitable topics include investigations into the biology and ecology of wildlife and their habitats that has direct or indirect implications for wildlife management and conservation. This includes basic information on wildlife habitat use, reproduction, genetics, demographics, viability, predator-prey relationships, space-use, movements, behavior, and physiology; but within the context of contemporary management and conservation issues such that the knowledge may ultimately be useful to wildlife practitioners. Also considered are theoretical and conceptual aspects of wildlife science, including development of new approaches to quantitative analyses, modeling of wildlife populations and habitats, and other topics that are germane to advancing wildlife science. Limited reviews or meta analyses will be considered if they provide a meaningful new synthesis or perspective on an appropriate subject. Direct evaluation of management practices or policies should be sent to the Wildlife Society Bulletin, as should papers reporting new tools or techniques. However, papers that report new tools or techniques, or effects of management practices, within the context of a broader study investigating basic wildlife biology and ecology will be considered by The Journal of Wildlife Management. Book reviews of relevant topics in basic wildlife research and biology.
