Abstract: Two sightability models were developed from summer helicopter surveys of radiocollared elk (Cervus elaphus) in Grand Teton National Park, Wyoming. Significant variables included elk group size, activity, and percent vegetation cover for Model A, and elk group size and percent vegetation cover for Model B. These summer models were compared to a winter elk sightability model developed in Idaho that incorporated group size, percent vegetation cover, and percent snow cover. Studies the development and sightability models for summer elk surveys in the United States. Methodology; Model comparison; Discussion on the results of the study. A sightability model was developed to account for visibility bias in aerial censuses and classifications of elk in the Jackson herd unit. The model was used to correct estimates of the number of elk that summer in Grand Teton National Park.
