Absolute and relative counts of edge, perforated, and interior cells. Counts of cells for each selected fragmentation index class; from left in both rows: edge, perforated, and interior. The first row shows absolute count of cells while the second row shows count of cells under the vegetation surface divided by the number of all cells under the vegetation surface. The absolute count of edge cells seems to be associated with higher vegetation, but unlike the view provided by slices in Fig. 7, the vegetation on the edge of the areas is not visible as a separate group. Worth noting is the difference between absolute and relative count of interior cells (last column). The absolute count shows the whole south-east quadrant as mostly consistent while the relative count shows it as two distinct groups
