Western Arctic Caribou Herd Range

The Alaska Department of Fish and Game (ADFG) maintain radio collar and satellite telemetry data for the Western Arctic herd. ADFG summarized the telemetry data as kernel densities to delineate the total annual distributions of the caribou herd. Collar location data points were extracted from the entire annual cycle from 2004 to 2014 for the Western Arctic herd. The set of points served as the input for kernel density calculations. Kernel density was calculated for individual years and the results were summed to capture annual variability in caribou habitat use. Through a data sharing agreement between ADFG and ACCS, these kernel densities were made available to ACCS. Kernel densities are based on the daily positions of a small subset of individuals from the total herd.
