Install barrier fencing along railways
Overall effectiveness category Unknown effectiveness (limited evidence)
Number of studies: 1
Background information and definitions
Collisions with trains can cause substantial numbers of mammal deaths (e.g. Gundersen & Andreassen 1998). Barrier fencing alongside railways may reduce access to railway tracks by mammals and, thus, reduce the number of mammal-train collisions.

Supporting evidence from individual studies
A before-and-after study in 1985–2003 in forest in southern Norway (Andreassen et al. 2005) found that 1 km of fencing eliminated moose Alces alces collisions with trains along that stretch. The exception was one killed at the fence end. Within the wider study area, there were 0.58 moose/km killed each winter during the study period. In 1995, a 1-km-long wire-mesh fence was erected alongside a railway line. Moose-train collisions along a 100-km stretch of the railway line were recorded from July 1985–April 2003.Study and other actions tested
