This U.S. Geological Survey Data Release includes maps of Phragmites australis coverage within the Delta National Wildlife Refuge (NWR), located on the eastern half of the Mississippi River Delta in south Louisiana, for 2011, 2013 and 2016. While the objective of this mapping effort was to map the presence of P. australis, the map also includes coverage of water and non-P.australis land areas (e.g., non-P. australis emergent marsh with scrub/shrub, developed, etc.) and water (e.g., open water, submerged aquatic vegetation, floating aquatic vegetation, and nonpersistent wetlands). This data release also includes maps that show spatial change in P. australis coverage between mapping efforts. This specific dataset is a map of P. australis and other general land cover (non-P. australis land and water) for Delta NWR for 2016. This compressed file contains five shapefiles: (1) Delta_NWR_Phragmites_Map_2011.shp - ESRI shapefile containing habitat classes. (2) Delta_NWR_Phragmites_Map_2013.shp - ESRI shapefile containing habitat classes. (3) Delta_NWR_Phragmites_Map_2016.shp - ESRI shapefile containing habitat classes. (4) Delta_NWR_Phragmites_Change_2011_2013.shp - ESRI shapefile containing Phragmites australis change between 2011 and 2013. (5) Delta_NWR_Phragmites_Change_2013_2016.shp - ESRI shapefile containing Phragmites australis change between 2013 and 2016.
