TNC Conservation Portfolio

The Nature Conservancy has been a leader in spatial conservation planning for many years. The primary planning tool used by the Conservancy for landscape-scale conservation planning over the past decade has been Ecoregional Assessments. Our United States Ecoregional Assessments identify priority areas for conservation within the United States. This includes data from 67 Ecoregional Assessments, which identified over 9,000 conservation priority areas. Importantly, this dataset contains the conservation targets that we hope to conserve within these priority areas. Conservation targets include both species and habitat types (e.g. plant communities; ecosystems). Our dataset includes 8,507 unique species and 6,633 habitat types. Across the United States a common naming system was used for our species targets. In contrast, names for habitat targets may be specific to each ecoregion. Additional information about each ecoregional assessment, including vintage, stakeholder participation, and other methodology, is available at http://east.tnc.org.
