Considerations for Developing Wolf Harvesting Regulations in the Contiguous United States

Abstract: As gray wolves (Canis lupus) are removed from the federal Endangered Species List, management reverts to the states. Eventually most states will probably allow public wolf harvesting. Open seasons between about 1 November and 1 March accord more with basic wolf biology than during other times. Managers who consider wolf biology and public sensitivities, adapt public-taking regulations accordingly, and adjust harvest regulations as they learn will be best able to maximize the recreational value of wolf harvesting, minimize public animosity toward it, and meet their harvest objectives.     

Spatial and Temporal Patterns of Wolf Harvest on Registered Traplines in Alberta,Canada

Abstract: Gray wolf (Canis lupus) populations are recovering in many parts of the world and managers from various jurisdictions will be faced with difficult decisions as wolf populations continue to increase. Wolf management in Alberta, Canada, is achieved mostly through trapping on a registered trapline system. Wolf harvest increased over the last 22 years relative to population increases. Most wolf harvests occurred in the Rocky Mountains and surrounding foothills area and this pattern was consistent over time. On average, trappers only harvested an estimated 9.8% of the provincial population annually despite the lack of bag limits or quotas. Harvests are spatially autocorrelated with peak autocorrelation coinciding with average home-range size for wolves in Alberta. When wolf control actions are deemed necessary, trappers are unlikely to remove a sufficient number of wolves over a large enough area to limit subpopulations under the registered trapline system.     

Additional considerations for gray wolf management after their removal from Endangered Species Act protections

Mech (2010) provided a review of options involving regulated, public hunting of gray wolves (Canis lupus) when states regain control of wolf management. We agree with his general conclusion that the use of lethal management should focus more in areas of conflict and less in wilderness areas, especially near protected places like national parks. Here, we expand on Mech's work and provide additional considerations that could be incorporated into state management plans to make them more acceptable to an increasingly diverse group of interested stakeholders, including: 1) the use of human dimensions research to understand the conditions under which stakeholders find lethal management acceptable, and to evaluate the acceptability of agency efforts to increase tolerance for wolves; 2) employing preventative measures to protect livestock and pets, especially in cases where wolf packs are highly visible to the public; and 3) selective use of sport hunting in areas where wolf impacts are deemed unacceptable. © 2011 The Wildlife Society.     

Long-Distance Dispersal of a Rescued Wolf From the Northern Apennines to the Western Alps

ABSTRACT By using Global Positioning System technology, we documented the long-distance dispersal of a wolf (Canis lupus) from the northern Apennines in Italy to the western Alps in France. This is the first report of long-distance dispersal of wolves in the human-dominated landscapes of southern Europe, providing conclusive evidence that the expanding wolf population in the Alps originates from the Apennine source population through natural recolonization. By crossing 4 major 4-lane highways, agricultural areas, and several regional and provincial jurisdictions, the dispersal trajectory of wolf M15 revealed a single, narrow linkage connecting the Apennine and the Alpine wolf populations. This connectivity should be ensured to allow a moderate gene flow between the 2 populations and counteract potential bottleneck effects and reduced genetic variability of the Alpine wolf population. The case we report provides an example of how hard data can be effective in mitigating public controversies originating from the natural expansion and recolonization processes of large carnivore populations. In addition, by highlighting the connectivity between these 2 transboundary wolf populations, we suggest that documenting long-distance dispersal is particularly critical to support population-based, transboundary management programs.
