Landscape fragmentation in FUAs in 2018 in the EU-27 and the UK region, by country and FUA structure

Fragmentation is measured as the density of continuous, i.e. unfragmented, semi-natural landscape elements (i.e. meshes). This is calculated by dividing the number of meshes with a unit area, e.g. 1 or 1 000 km². If the landscape is not fragmented, i.e. it consists of a completely continuous landscape, the mesh density is 1. If the number of natural and semi-natural landscape elements in a unit area increases, the landscape becomes more fragmented and the mesh density increases.

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, including medium sized 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 EEA-39.
