Abstract

Shapefile recording the federal protection classifications of roughly 253,000 wetlands in New York State, sourced from the National Wetlands Inventory (NWI). Wetland polygons were obtained from the National Wetlands Inventory (NWI). Wetlands are classified under both the Clean Water Rule (CWR) and the Navigable Waters Protection Rule (NWPR) based on the NHD stream network. Adjacent wetland polygons were merged to prevent errors in classification. See manuscript for full description of wetland filtering.
