This GIS data set represents mangroves in the coastal areas of Florida as mapped in the September 2003 delivery of Environmental Sensitivity Index (ESI) shoreline classification polygons. This GIS data set was reselected from the shoreline classification based on the MANGROVE attribute equal to "Y" (yes). Research Planning Inc. (RPI) developed the ESI classification polygons based on the 1994-1995 land use and land cover for all of Florida's water management districts, with the exception of the Southwest Florida Water Management District (SWFWMD), which was classified based on 1999 DOQQs. At FMRI's request, RPI also reworked some shoreline in the South Florida Water Management District (SFWMD), which had poor positional accuracy.
These data do not represent mangroves in Florida's interior areas, and they do not represent "fringing" mangroves. However, "fringing" coastal mangroves are represented in the companion data set "mangrove_coastal_esi_arc", which was derived from the ESI arc classification data set.
