Full Metadata This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas). The layers in this web service are derived from a dataset produced by Forest Trends' Ecosystem Marketplace containing points and polygons depicting the location of market-based programs and projects addressing ecosystem services protection and their enabling conditions in the United States.This dataset contains polygons representing guidance, enabling policies, and regulatory drivers that facilitate ecosystem services markets per Ecosystem Marketplace research. It includes conditions that specifically establish ecosystem market mechanisms, as well as conditions that indirectly function as the regulatory driver for ecosystem markets. Data cover watershed, imperiled species and habitats, wetland and streams, and forest and land-use carbon asset types. Scales represented include watershed (HUC8), state, regional, national, and federal lands. EnviroAtlas allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the conterminous United States as well as detailed metrics for select communities. Additional descriptive information about each attribute in this web service can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
