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 dataset was produced by the US EPA to support research and online mapping activities related to the 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). These results, in conjunction with further data and verification, could help planners identify, prioritize and implement locally relevant efforts. The overall goal of the 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 U.S. Environmental Protection Agency, Office of Research and Development-Sustainable and Healthy Communities Research Program, EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

For the purpose of this metric, subclasses of land cover (e.g. ranging from barren to high intensity development) and wetland restoration potential (low, moderate, and high) were summarized into two general classes representing land cover and potentially restorable wetlands. The land cover and potentially restorable wetland areas were summarized per watershed, combined, and a percentage estimate of potentially restorable wetlands in agriculture per total land cover per 12-digit HUC watershed was calculated.

This lineage was generated by the FGDC CSDGM to 19139 transformation 1. ArcGIS 10.2.1 was used for processing. 2018-07-20T00:00:00 2. Prepared the watershed layer - The watershed layer (12-digit HUCs) was converted from polygons to 30-meter grid cells (raster) and aligned (snapped) to the National Land Cover Dataset (NLCD). 2018-07-20T00:00:00 3. Calculated the total land cover - Categorized (reclassed) all NLCD classes, except Open Water (11) which was reclassed to 0, into a single land cover class (1). Open Water was excluded to be consistent with other EnviroAtlas HUC percentages calculated with the Analytical Tools Interface for Landscape Assessments tool (ATtILA, www.epa.gov/enviroatlas/attila-toolbox). Used Zonal Statistics as Table to summarize the total land cover cells per 12-digit HUC. 2018-07-20T00:00:00 4. Calculated the potentially restorable wetlands land cover - The Potentially Restorable Wetlands on Agricultural Land raster dataset contains three classes of potential restoration (and one class that does not indicate potential for restoration with the specified criteria). For the purposes of this dataset, these three classes that indicated wetland restoration potential were reclassed into one class, potentially restorable wetlands (1), and the class in which potential restoration was not evident remained classed as 0. Used Zonal Statistics as Table to summarize the total potentially restorable wetland land cover per 12-digit HUC. 2018-07-20T00:00:00 5. Calculated the percent land cover with potentially restorable wetlands - Joined the Zonal Statistics results (Sum) for land cover and potentially restorable wetlands to the 12-digit HUC polygon layer. Exported the joined tables. Added a new field (PctPRWAg) and calculated the percent potentially restorable wetlands per total land cover per 12-digit HUC. 2018-07-20T00:00:00 unknown 2029-02-11 This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2024-02-09T11:11:00 version of the FGDC CSDGM to ISO 19139 transform.
