We are developing a new climate change vulnerability assessment for priority ecosystems in the Midwest and Northeast United States. The new assessment, Ecosystem Vulnerability in the Eastern Region (EVER), will expand on our previous assessments in several ways. Specifically, the new assessment will:  

  • Cover the full geographic extent of the 20-state Eastern Region, rather than being constrained to major forested landscapes
  • Include a wider variety of terrestrial ecosystems, spanning forests, grasslands, and wetlands
  • Utilize the U.S. National Vegetation Classification to describe ecosystems in a consistent way across the region
  • Divide the landscape according to the 2025 ECOMAP updated Ecological Provinces (Figure 1)

Despite these updates, the core of the EVER assessment will remain consistent with the previous vulnerability assessments we have produced. The assessment will synthesize information from ecosystem models, published research, Indigenous Knowledge, and land manager expertise to present the best available science. The assessment will serve as a foundational resource for the region, focusing on the needs of land managers, forest stewards, and planners. Producing the assessment will involve collaboration between participants from federal, state, tribal, nongovernmental, private sector, and academic organizations. Assessment results will be disseminated via a written report published by the USDA Forest Service Northern Research Station, as well as an online tool. The report will provide details about provinces and ecosystems in the region and the companion tool will enable users to interact with spatial data and explore assessment results at multiple scales. Assessment writing and development is ongoing in 2026.

Over 200 people from across the land management community are already participating in the EVER assessment. Assessment writing and development is ongoing in 2026. Please contact Stephen Handler (stephen.handler@usda.gov) with any questions about the effort.

Figure 1. Ecological Provinces are units of land defined by major climate zones, native vegetation, and biomes such as prairies, deciduous forests, or boreal forests. The 20-state region of the Midwest and Northeast United States contains 17 Ecological Provinces, as defined by the 2025 ECOMAP update.
