How many caribou herds use NPR-A for calving and migration?

Question

Accepted Answer

NPR-A provides habitat for three of the four caribou herds on Alaska's North Slope: the Teshekpuk herd, the Western Arctic herd, and the Central Arctic herd. These herds use NPR-A's open tundra for calving, foraging, migration corridors, and winter habitat. The Teshekpuk herd alone numbers tens of thousands of caribou that depend on lakeside wetlands during vulnerable calving periods. Caribou populations have experienced sharp global declines in recent years due to climate change and habitat disruption. Drilling infrastructure fragments calving grounds and disrupts migration patterns. The wetlands around Teshekpuk Lake provide mosquito relief and predator protection that caribou need during calving season. Iñupiat communities depend on these herds for subsistence hunting, food security, and cultural identity.
