The Circumboreal Vegetation Mapping (CBVM) project is an international collaboration among vegetation scientists to create a new vegetation map of the boreal region at a 1:7.5 million scale with a common legend and mapping protocol. This report and map contributes to the CBVM effort by developing maps of bioclimatic zones, geographic sectors with similar floristic variability, and vegetation in boreal Alaska, Yukon, northwestern British Columbia, and a mountainous portion of southwest Northwest Territoriestermed the Alaska-Yukon region. It further develops the mapping from the initial classification and proto-type mapping efforts for southwestern Alaska and western Canada to this broader area.
