The barriers are shown in black (built-up areas, roads, railways), and the colours indicate the sizes of the remaining patches in the landscape. Lake Constance and Lake Geneva are visible at the top and on the left of the map, respectively. In FG-B2, the lakes and mountains were considered as barriers, but were not included in the reporting units.
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.
