Map of Alaska's 32 Caribou Herds
Map of Alaska’s 32 caribou herds, which are defined by their calving grounds. The map shows general distribution over annual migration, which can change from year to year depending on conditions and food availability. Produced in 2011 by the Alaska Department of Fish and Game from photo-census counts; herd size cycles naturally over different time scales and can also change due to many other factors, including climate influences.
