This dataset represents areas of high habitat heterogeneity within the Re-evaluating Florida's Ecological Conservation Priorities in the Face of Sea Level Rise project study area. Features in this dataset are those portions of the project study area where more than 6 unique natural land cover classes exist within a 25 hectare window. These features were identified through a focal statistics raster analysis of the FL_LandCoverCoastal_FNAI dataset within a coastal analysis zone defined as areas in Florida of equal to or less than 3 meters elevation plus a 1 kilometer buffer. The features in this dataset are considered "refuges" because they intersect areas of equal to or greater than 3 meters. Because of their high habitat heterogeneity and their elevation, these areas may be able to function as refuges for species migrating inland to escape sea level rise. This dataset complements FL_HabHetSources_FNAI.
