Five types of fragmentation are illustrated, and land use in and around the Ocala National Forest illustrates how these are relevant to management decisions.

WebSep 29, 2014 · Habitat patches are uniquely identified by a patch flooding algorithm. Two habitat cells in the land cover raster are considered connected if they are adjacent in either a cardinal or diagonal direction. This is the same neighborhood used in the movement rules, so an individual can move to any cell in the patch without entering non-habitat.
