Install tunnels/culverts/underpass under roads
A study in 2004–2006 in an area of rice fields and scattered forest in Jeollanamdo province, South Korea (Choi & Park 2007) found that highway underpasses were used by a range of mammals, though road sections with higher underpass density did not have fewer wildlife-vehicle collisions. Eleven wild mammal species were recorded using underpasses. The most frequent were raccoon dog Nyctereutes procyonoides (865 images), brown rat Rattus norvegicus (455), leopard cat Prionailurus benalensis (253), striped field mouse Apodemus agrarius (229), Siberian weasel Mustela sibirica (166), Eurasian otter Lutra lutra (35) and water deer Hydropotes inermis (32). Ninety-three roadkill mammals of 12 species were recorded. The most frequent were rodents (24 casualties), leopard cat (17), Siberian weasel (13) and water deer (12). Most mammals used all underpass types frequently, except water deer, which rarely used small passages. Use of seven circular culverts (0.8–1.2 m diameter), two box culverts (2.5 m wide and high) and five human underpasses (2.0–4.3 m wide and high), selected from 31 underpasses along a 6.6-km section of four-lane highway, were monitored from September 2005–August 2006. One or two infrared-operated cameras were installed 1–2 m inside each underpass for an average of 239 days/underpass. Wildlife-vehicle collisions were recorded daily from September 2004–August 2006.
