We developed seasonal resource selection functions for moose on the Kenai Peninsula to inform the habitat connectivity modeling used to evaluate the impacts of existing and future infrastructure developments, in particular highways. During all seasons, the probability of moose use of an area was positively associated with increasing distance from human activities (recreation site, road, or trail) and areas with vegetation types that provided both cover (mixed and evergreen forests) and forage (shrublands, wetlands). Habitat connectivity modeling subsequently identified several habitat linkages across multiple seasons despite differences in resistance surfaces. However the degree that the linkages were constrained (based on the pinch-point analyses) varied by season; linkages were most highly constrained during autumn and least constrained during spring. Our results can be applied locate crossing structures and other mitigations that could reduce moose-vehicle collisions and provide for connected moose habitats.

摘要

We developed seasonal resource selection functions for moose on the Kenai Peninsula to inform the habitat connectivity modeling used to evaluate the impacts of existing and future infrastructure developments, in particular highways. During all seasons, the probability of moose use of an area was positively associated with increasing distance from human activities (recreation site, road, or trail) and areas with vegetation types that provided both cover (mixed and evergreen forests) and forage (shrublands, wetlands). Habitat connectivity modeling subsequently identified several habitat linkages across multiple seasons despite differences in resistance surfaces. However the degree that the linkages were constrained (based on the pinch-point analyses) varied by season; linkages were most highly constrained during autumn and least constrained during spring. Our results can be applied locate crossing structures and other mitigations that could reduce moose-vehicle collisions and provide for connected moose habitats.
