Migration and Movement

USGS assists state fish and wildlife agencies, land and wildlife managers, and other stakeholders by producing applied science-based tools to guide wind and solar energy development to locations where it will have minimal impact on wildlife. As a basis for these tools, USGS researchers study the movement and migration of wildlife.

Mammals

For big game, USGS research on migrating animals interacting with housing and energy development suggests that this development and change to migration routes can alter optimal foraging. Continued energy development will lead to the loss of the foraging benefit of migration.
