Alaska & Canada Pacific Coastal

WWF Abstract

The Alaska and Canada Pacific Coastal ecoregion contains watersheds that drain all waters west of the continental divide in areas that were only deglaciated in the last 10,000 years. Therefore, the fauna is relatively young and limited to species present in Pacific and Beringian refugia during the last Ice Age. The coastal islands within this ecoregion contain waterbodies that were formed since the retreat of the last Ice Age (ca. 10,000 years ago) and have been periodically inundated by the Pacific Ocean. As a result, the freshwater fish fauna is depauparate, but with several endemic species, and is comprised of species with some saltwater tolerance.
