Viewsheds Across Ecosystems
Viewsheds are directly influenced by habitat structure but habitat structure varies dramatically in different ecosystems. We are investigating the influence of ecosystem on viewsheds and selection of viewsheds.

Methods of Viewshed Estimation
Because wildlife move through three-dimensional habitats and habitat structure directly influences viewsheds, estimation of viewsheds in 3D is critical. However, until recently methods have been limited to either 2D estimations or to small extents. We are testing and refining 3D methods of viewshed estimation at multiple scales.

Viewshed Selection by Red Squirrels
American red squirrels (Tamiasciurus hudsonicus) build larders called middens where they store food. Middens are used and maintained through out the year and selection of secure midden sites is essential. We are investigating how the viewshed influences selection of these long-term sites.

Viewshed Selection by Pygmy Rabbits and Snowshoe Hares
Pygmy rabbits (Brachylagus idahoensis) and snowshoe hares (Lepus americanus) are closely related species that experience heavy predation but exhibit different anti-predator behaviors. We are investigating how these differences influence their perceptions of risk and viewshed selection. Click here to learn more about pygmy rabbits and snowshoe hares.
