The Eastern Conservation Science team is a group of scientists and spatial analysts who work on regional-scale conservation issues. With over 100 years of combined conservation experience, the strategic work done by this science analysis and mapping team informs The Nature Conservancy’s priority planning and conservation actions across 22 states in the Eastern U.S. The team’s data products and reports are also used for natural resource planning by over 60 other conservation organizations as well as over 20 state and federal agencies.
