This dataset shows a series of fragmentation metrics for natural vegetation for a 4KM reporting unit. These metrics were calculated using FRAGSTATS. For more information about FRAGSTATS, or the methods used to calculate these metrics, please see: http://www.umass.edu/landeco/research/fragstats/fragstats.html Fragmentation metrics were caculated for a 3x3 reporting unit grid (4KM each) neighborhood centered on each reporting unit grid cell. This was done to prevent edge effects due to the smaller size of the reporting units relative to the size of larger patches in more intact landscapes. A 90 meter edge distance was used to define core area within patches.
