Summary
Arctic char have been documented in lakes and outlet streams in the Brooks Range, the Kigluaik Mountains, the Kuskokwim Mountains, the Alaska Peninsula, Kenai Peninsula, Kodiak Island, and in a small area of Interior Alaska near Denali National Park and Preserve. However, a comprehensive survey of Alaska water bodies that contain Arctic char is lacking. The vast majority of lakes and rivers where they have been surveyed and found are within Federal lands such as the National Petroleum Reserve-Alaska, Arctic National Wildlife Refuge, Gates of the Arctic National Park, Noatak National Preserve, Togiak National Wildlife Refuge, and others. Most populations of Arctic char are well off the road system. Throughout most of their potential range, basic population-based information such as presence, life history, trophic morphology, genetic variability, abundance and growth is largely unknown.
