Abstract: We developed a logistic model based on a conjoint analysis approach to evaluate the cumulative effects of selected forms of human disturbance on bald eagles (Haliaeetus leucocephalus) in their natural habitat. The dependent variables were amount of habitat available to bald eagles for foraging and perching as a function of 5 human disturbance factors. Application of the model to a section of the Snake River in Grand Teton National Park where detailed information on levels of human intervention were known yielded reasonable values when compared to field observations. The model is currently in use by managers of the Bridger-Teton National Forest and Grand Teton National Park. Evaluates the cumulative effects of selected forms of human disturbance on bald eagles in their natural habitat. Methods; Model results; Model validation; Discussion; Management implications.
