Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research studies and management decisions. Since the mid-1980s, the USGS Alaska Science Center has collected data from wildlife tracking devices to: determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on various behaviors, determine timing of life cycle events, and identify geographic areas repeatedly used by wildlife that may be of significance to other species and populations.

  These datasets are a collection of the USGS Alaska Science Center wildlife tracking data arranged by species or closely allied species groups. Details of tracking projects, devices, methods, and data can be found within each species directory.
