There is a potential for decreased water quality in areas where the riparian buffer is less forested. The displayed line represents the center of the analyzed riparian buffer. The water bodies analyzed include hydrologically connected streams, rivers, connectors, reservoirs, lakes/ponds, ice masses, washes, locks, and rapids within the Atlas Area. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). The purpose of this dataset is to describe the forest cover within a 15m riparian buffer along streams, rivers, and lakes within the Atlas Area. In combination with the Riparian Buffer Land Cover Block Group Summaries, this data can be used to assess areas within 15m riparian buffers that would benefit from additional tree coverage. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator US Environmental Protection Agency, Research Triangle Park ORD/NERL/EnviroAtlas 000-000-0000 109 TW Alexander Dr. Research Triangle Park NC 27711 EnviroAtlas@epa.gov pointOfContact asNeeded Ecosystem Environment theme EPA GIS Keyword Thesaurus Communities Drinking Water Ecosystem Services EnviroAtlas Environment Environmental Atlas Ground Water Impact Land Cover Natural Resources Riparian Surface Water Water theme EnviroAtlas Massachusetts New Bedford, MA place None https://edg.epa.gov/EPA_Data_License.htm otherRestrictions Use Constraints: None.
