A plant community-level map of arctic Alaska was derived in a hierarchical fashion from the Circumpolar Arctic Vegetation Map (CAVM). The new map has 33 units described for Alaska, an increase from the original 13 units shown on the CAVM. The polygons of the new map refer through the legend to the appropriate dominant plant community described in a table. The table includes eighty-five plant community descriptions used in creating the Alaska portion of the CAVM, including dominant and characteristic plant species that define the community, literature citations for the descriptions and published plant community names. Researchers can use the literature citations to find more complete species lists, habitat descriptions and plot locations. The map is an important tool for research and management at the regional level. A 1: 4,000,000 version of the map is available from the authors. Keywords: tundra, plant physiognomy, arctic bioclimate subzones, floristic provinces, topographic gradient, soil pH. Phytosociology. Characteristic lichens of Arctic Alaskan communities listed.
