  • One study evaluated the effects on mammals of installing barrier fencing along railways. This study was in Norway.



  • Survival (1 study): A before-and-after study in Norway found that fencing eliminated moose collisions with trains, except at the fence end.


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.
