Abstract
The management of big game harvest is important for maintaining viable populations and providing recreational opportunities to hunters. There are numerous strategies used by management agencies to achieve these goals, but they are complicated by variation in factors that are difficult to control, such as harvest success rates. For harvest management decisions to have the desired effect on big game populations, the mechanisms affecting factors like harvest success rates need to be properly understood. We used Bayesian hierarchical survival models to explore the factors influencing spatial and temporal variation in moose (Alces alces) harvest success rates in Ontario, Canada. We estimated harvest success rates from hunter reports from 59 Wildlife Management Units from 2000–2019. Overall, harvest success rates were primarily influenced by variables under the control of management agencies, such as season length and tag allocations, but they were also affected by external factors like moose density and weather. Season length, while positively related to harvest success for shorter seasons (e.g., <25 days), exhibited limited influence for longer seasons (>25 days). Our results were largely consistent across spatial and temporal scales, with a similarly strong positive effect of moose density and negative effect of tag allocation between management units and across years. This study emphasizes the need for managers to recognize the inherent uncertainty in harvest outcomes beyond their control and the importance of open communication with hunters in achieving effective harvest management, while offering concrete pathways for influencing harvest success.
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.
