Figure Illustration of the behaviour of five landscape metrics in the phases of shrinkage and attrition of the remaining parcels of open landscape due to the growth of an urban area
First row: change of the landscape over time (black lines = highways, black area = residential or commercial area; size of the landscape: 4 km × 4 km = 16 km2). Only the effective mesh size behaves in a suitable way (bottom diagram). APS and n both exhibit a jump in their values (even though the process in the landscape is continuous); DTL and nUDA100 do not respond to the increase in fragmentation. (meff = effective mesh size, n = number of patches, APS = average patch size, nUDA100 = number of large undissected low-traffic areas > 100 km2, DTL = density of transportation lines).

Figure Example illustrating the relationship between effective mesh size and effective
In this hypothetical example, the trend remains constant. A linear rise in effective mesh density (right) corresponds to a 1/x curve in the graph of the effective mesh size (left). A slower increase in fragmentation results in a flatter curve for effective mesh size, and a more rapid increase produces a steeper curve. It is therefore easier to read trends off the graph of effective mesh density (right).
