The objective of this task is calculate “effective mesh size” as indicator of landscape fragmentation. Effective mesh size (Meff) is proportional to the probability of two points chosen randomly in region being connected. This probability is then converted into the size of a patch – the effective mesh size. The unit of Meff is that of area (e.g. Ha). This area corresponds to the size of “meshes” of regular network that has the same degree of fragmentation and it can be compared with the values of Meff from other regions. The smaller the effective mesh size, the more fragmented the landscape.

Additional information
Many protected areas are located in regions that contain large unfragmented patches. River systems that are protected are
visible as black lines. Depending on the particular objectives of a study, differing FGs are most suitable.
