Cougar-Wolf Interactions in Yellowstone National Park: Competition, Demographics, and Spatial Relationships
Ruth T. Cougar-Wolf Interactions in Yellowstone National Park: Competition, Demographics, and Spatial Relationships
This article is a description of Phase II of Hornrocker Wildlife Institutes Yellowstone Cougar research to date. The purposes of this portion of the study were the quantification of cougar ecology with focus on relations between cougars and wolves and cougars and their prey in the Greater Yellowstone Ecosystem. Specific objectives are detailed in the report, as are results of the first three years of data collection. The project documented 161 cougar kills, 144 of them ungulates, 33% of which were then scavenged or taken over by other carnivores. Ground and aerial locations were obtained and then investigated to collect habitat information. Two cougars and two wolves have been radio-collared to collect location data at simultaneous times during the day. A future report is expected.
