This EnviroAtlas dataset shows the acres of land enrolled in the US Department of Agriculture (USDA)'s Conservation Reserve Program (CRP). The CRP is administered by the Farm Service Agency; farmers in the program receive annual payments and establishment cost share to remove environmentally sensitive land from crop production and instead plant perennial species that provide environmental benefits. This dataset was produced by the USDA to support research and online mapping activities related to EnviroAtlas.

This EnviroAtlas dataset represents land cover across a watershed and in riparian areas for each 12-digit hydrologic unit code (HUC) in the conterminous United States for use in the Compare my Area tool.

This EnviroAtlas dataset shows the percent land cover with potentially restorable wetlands on agricultural land for each 12-digit Hydrologic Unit (HUC) watershed in the contiguous U.S. Beginning two centuries ago, many wetlands were turned into farm fields or urban areas, yet wetlands play an important role in removing water pollution, regulating water storage and flows, and providing habitat for wildlife. Wetland restoration could help restore these benefits. Potentially restorable wetlands, as developed for this map, are lands currently in agriculture that naturally accumulate water due to topography and have historically had poorly or very poorly draining soils.

This EnviroAtlas dataset represents the percentage of land area that is classified as forest, forest including woody wetlands, and natural land cover that occurs within 45 meters of streams, rivers, and other hydrologically connected waterbodies within each 12-digit hydrologic unit code (HUC) in the conterminous United States. Land cover is defined using the 2019 National Land Cover Dataset (NLCD). Streams were derived from the NHD (National Hydrography Dataset) High Resolution dataset obtained 4 January 2022. Datasets for other geographies were produced separately; metadata for these related datasets may be found here: Alaska https://enviroatlas.epa.gov/enviroatlas/MetadataFGDC/RiparianLC_AK.xml, Hawaii https://enviroatlas.epa.gov/enviroatlas/MetadataFGDC/RiparianLC_HI.xml, Puerto Rico and the U.S. Virgin Islands https://enviroatlas.epa.gov/enviroatlas/MetadataFGDC/RiparianLC_PRVI.

This EnviroAtlas dataset represents the percentage land area that is classified as agricultural land cover that occurs on slopes above a given threshold for each 12-digit hydrologic unit code (HUC) in the conterminous United States. Agricultural land cover is defined using the EnviroAtlas hybrid Cropland Data Layer (CDL) - 2011 National Land Cover Dataset (NLCD). Percentage slope values were derived from the 1 arc-second National Elevation Dataset (NED). This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas.

This EnviroAtlas dataset estimates the average agricultural buffer width, the percentage of agricultural lands with flow paths that would intersect natural land cover before reaching a stream, and the percentage of each subwatershed (12-digit HUC) that is unbuffered agricultural land. Subwatershed summaries are calculated for the contiguous United States. The map uses a combined land use/land cover map from the 2006 National Land Cover Database (NLCD) and the 2010 Cropland Data Layer (CDL). It combines agriculture, forests, grasslands and wetlands with stream networks and elevation datasets in flow path models to find agricultural flow paths that do or do not intersect buffers, and counts the agricultural flow paths through buffers adjacent to streams in order to determine average buffer widths on agricultural lands.
