Fig. 5. Data on the current (2004) degree of landscape fragmentation in the 44 rural districts of Baden-Württemberg (including municipal roads). Two methods were compared: the cutting-out (CUT) procedure (dark bars) and the central-point (CTRP) procedure (light bars; see text for explanation of the methods). The order of the rural districts is according to increasing values of the effective mesh size (meff) as measured by the CUT procedure. For comparisons, the value of the meff of the entire state of Baden-Württemberg is shown by a solid line (13.01 km²).
