Description:
The STA (Swedish Transport Administration) regularly monitor the permeability of the transport infrastructure on ungulates.
Several steps were used to identify infrastructure barriers:
• Identification of infrastructure barriers;
• Identification of crossing points for fauna;
• Quantification of remaining barriers.
The results are used on many levels. Quantified data on the extent of the barriers are used by the government to define a target for defragmentation and allocate funding for defragmentation measures. Based on the analysis, STA prioritizes and distributes funding to regional and local levels and monitors the yearly progress towards the set target.
