Recreation, Fire And Disease Create A Mosaic Of Threats For Golden Eagles In Southwestern Idaho, Caitlin Marie Davis
Boise State University Theses and Dissertations
Anthropogenic stressors have resulted in ecosystem impoverishment and biodiversity loss worldwide. As the strength and reach of the human footprint increases, investigation of the additive or interactive effects of synergistic stressors on the landscape is imperative for conserving ecosystems and species within them. Apex predators can reflect how stressors impact ecosystems because of bottom-up effects. Golden eagles (Aquila chrysaetos) are apex predators of North American sagebrush-steppe ecosystems that are impacted by a suite of stressors, including wildfire, outdoor recreation disturbance, and habitat loss. We investigated whether multiple threats had additive or interactive effects on golden eagle occupancy, reproduction, …

With rapid increases in outdoor recreation, and mounting evidence of impacts to wildlife, public land managers and biologists need better information on the nature of this potential disturbance. Outdoor recreation may impact wildlife negatively via human disturbance or habitat degradation. Golden eagles (Aquila chrysaetos) in shrub-steppe habitats face several current and emerging threats, including increased non-motorized and motorized (off-highway vehicle, OHV) recreation. We tested the hypothesis that recreation affects eagle breeding biology by monitoring eagle behavior and reproduction in response to recreation volume and activity types, and landscape features associated with recreation. We also investigated the probability that …
