Absolute and relative counts of fragmentation index classes. Number of cells in each fragmentation class for all selected zones in the study area (delineated in Fig. 5). The counts are only for the points under the vegetation surface (i.e. not including exterior cells above vegetation). The left image is the absolute count and the right image is the relative count, i.e. count divided by the height of the vegetation in cells. The x-axis numbers denotes the index classes: 0 is exterior, 1 patch, 2 transitional, 3 edge, 4 perforated, and 5 is interior as in Fig. 3; the lines in between the numbers have only visualization purpose. The relative count (right) shows, for example, zones 4 and 6 as the most different ones from each other, while absolute count (left) shows zone 3 (large deciduous tree in the middle) as the most unique one. Both plots show minimum of cells with a patch class; this is mostly due to the choice of the size of the moving window in fragmentation index computation
