    • EnviroAtlas - 2016 Riparian Land Cover Proportions by 12-Digit HUC for Alaska

    Metadata Updated: October 14, 2024

    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 Alaska. Land cover is defined using the 2016 National Land Cover Dataset (NLCD). Streams were derived from the NHD (National Hydrography Dataset) High Resolution dataset obtained June 2020. 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).
