The Alaska Species Ranking System (ASRS) is a prioritization tool that assesses the conservation status of native vertebrates in Alaska. It was developed in collaboration with the Alaska Department of Fish and Game’s Threatened, Endangered, and Diversity (TED) Program. The goal of the ASRS is to provide detailed information on the conservation needs of Alaska’s wildlife to help the TED Program and their partners set priorities for wildlife conservation and inform Alaska’s State Wildlife Action Plan.
The ASRS was initially developed in the mid-2000s. In 2012, the first version of the ASRS was released. Ranks have been regularly updated since then and there have been changes to the ranking system as well. In 2022, staff at ACCS and ADF&G used updated ranks to assess the conservation status of small mammal species in Alaska. In 2025, the ranking system was revised; the ranks shown here reflect the most recent changes. Please fill out a Data Request Form if you would like a copy of the ASRS assessment for one or more taxa.
