Figure 1.4.1 – Visualization of landscape fragmentation in Europe. The effective mesh density is a measure of the degree to which movement between different parts of the landscape is interrupted by a Fragmentation Geometry that is defined as the presence of impervious surfaces and transport infrastructure, including medium sized roads with more than 1,000 ADT. The more fragmented the landscape, the higher the effective mesh density (Source: EEA, 2021).
