More information

Coverage:
EEA39, without Cyprus, Iceland, Albania, Kosovo, Serbia, Cyprus, R. Macedonia, Romania, Bosnia and Herzegovina and Turkey due to poor data coverage of fragmentation geometries for this period

Methodology:
The Effective Mesh Density (seff) is a measure of the degree to which movement between different parts of the landscape is interrupted by a Fragmentation Geometry (FG). FGs are defined as the presence of impervious surfaces and traffic infrastructure, focusing only on major roads. The more FGs fragment the landscape, the higher the effective mesh density hence the higher the fragmentation. The geographic coverage of the dataset is EEA39.

Additional information:
EEA28 coverge is wihtout Romania due to poos TEelAtlas data coverage in 2009. EEA39 coverage excludes Cyprus, Iceland, Albania, Kosovo, Serbia, Cyprus, R. Macedonia, Romania, Bosnia and Herzegovina and Turkey due to poor data coverage of fragmentation geometries in 2009.

Unit:
seff, km2 and %

Based on data

Landscape fragmentation indicator effective mesh density (seff) - major and medium anthrophogenic fragmentation (FGA2_S_2016) The raster file is the basis of the indicator for assessing landscape fragmentation due to urban and transport expansion. The computation is based on the method of Effective Mesh Density (seff). The Effective Mesh Density (seff) is a measure of landscape fragmentation, i.e. the degree to which movement between different parts of the landscape is interrupted by a Fragmentation Geometry (FG). FGs are defined as the presence of impervious surfaces and traffic infrastructure. The Effective Mesh Density gives the effective number of meshes (or landscape patches) per 1000 km2, in other words, the density of the meshes. The more FGs fragment the landscape, the higher the effective mesh density. The seff values are reported within the 1km sq regular LEAC grid.
