Effective mesh density values by NUTS-X region for Fragmentation Geometry FG-B2 in 2009. Fragmentation geometry has been created from input data (TeleAtlas roads/rails, CLC urban classes, mountain areas / mountain ridges based on Nordregio and WorldClim data and rivers/lakes based on Catchment Characterisation and Modelling (CCM) v.2 database and CLC database) and landscape fragmentation metrics (Jaeger 2000) has been calculated.

Additional information

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.
