The Alaska Natural Heritage Program (AKNHP) in cooperation with the Bureau of Land Management (BLM), the Institute for Social and Economic Research (ISER), and the Scenarios Network for Alaska Planning (SNAP) have been developing Rapid Ecoregional Assessments (REAs) in Alaska. These assessments help evaluate current conditions and predict future conditions of the landscape and the effects of environmental influences on the region, including wildfire, invasive species, development, and climate change. REAs cover broad geographic regions, crossing different administrative boundaries and synthesize existing data over an 18-month period (BLM land use plans typically require 3-4 years). REA Manager Summaries are intended to answer important management questions, provide distribution maps for key resources, document potential impact from environmental change, identify science gaps, and provide baseline data for future management decisions.
