摘要: Moose (Alces alces) are currently widespread across Montana where regulated moose hunting has occurred since 1872, >140 years ago. The number of annual permits averaged 652 over the past 50 years. popular allocated via a random drawing, with an average ∼23,000 applicants in 2008-2012 who faced 1.9% chance success. Monitor- ing largely occurs through harvest statistics collected post-season phone surveys. Recent indicate lower hunter success, increased effort, and kill per unit concurrent >50% reduction available 1990s. Aerial surveys also show decline calf:adult ratios. In combination, these data suggest declining trend statewide population, despite some ambiguity certain data. Potential limiting factors include harvest, predation, vegetative succession degradation, parasites, climatic conditions, which were all identified as concerns state biologists. Accordingly, Fish, Wildlife Parks will direct funds derived from permit auctions toward calibrating refining monitoring methods research population dynamics potential moose.
