Cougar Predation Behavior in North-Central Utah

摘要: Cougar (Puma concolor) predation has been identified as being one of several factors contributing to the decline mule deer (Odocoileus hemionus) throughout Western United States. In order better understand how these elusive felines utilize their surroundings and prey, I examined analyzed cougar behavior in North-Central Utah, using global positioning systems (GPS) data from 2002-2010. Twenty-three cougars were fitted with GPS collars monitored for prey caching behavior. total 775 potential cache sites visited 546 remains found. Mule comprised majority at sites, but 11 other species also Collectively, adult female killed more than any demographic class. Proportionally there was no difference sex or age class by three different population segments, seasonal differences found number kills made between groups. Female kittens had a higher rate males solitary females, seasonally winter vs. summer. Cougars spent an average 3.3 days on kills, 6.2 elk kills. Habitat analyses suggested that preferentially used Gambel oak (Quercus gambelii) over land cover types when well selected unburned burned areas foraging prey. These results suggest dense stands vegetation stalking concealing Wildlife managers may want consider use prescribed burns high deer. This habitat manipulation tool could simultaneously help populations reducing percent afforded attempting kill along increasing nutrient levels newly foliage allow increased diversity forb shrub available
