The use of camera traps was employed in an effort to validate least-cost corridor (LCC) models developed for six focal wildlife species (black bear, brown bear, wolverine, Canada lynx, Dall sheep, and moose) within the Sterling Highway project area on the Kenai Peninsula, Alaska, USA. We deployed 40 camera traps, with 20 camera traps on both the north and south sides of the highway. Camera-trap days for the 40 cameras ranged from 278 to 394. Photgraphs were cataloged, recorded, and grouped into independent observations for each of the focal species. Independent observations were analyzed using a relative abundance index (RAI) to compare focal species use among the different camera locations and the LCC values associated with them. Evaluation of the relationship between number of animals expressed as RAI per 100 camera-trap days with values for LCC models revealed that focal species were found more often in areas with high connectivity (i.e., low LCC values).

摘要

The use of camera traps was employed in an effort to validate least-cost corridor (LCC) models developed for six focal wildlife species (black bear, brown bear, wolverine, Canada lynx, Dall sheep, and moose) within the Sterling Highway project area on the Kenai Peninsula, Alaska, USA. We deployed 40 camera traps, with 20 camera traps on both the north and south sides of the highway. Camera-trap days for the 40 cameras ranged from 278 to 394. Photgraphs were cataloged, recorded, and grouped into independent observations for each of the focal species. Independent observations were analyzed using a relative abundance index (RAI) to compare focal species use among the different camera locations and the LCC values associated with them. Evaluation of the relationship between number of animals expressed as RAI per 100 camera-trap days with values for LCC models revealed that focal species were found more often in areas with high connectivity (i.e., low LCC values).
