Install barrier fencing and underpasses along roads Terrestrial Mammal Conservation

A study in 2012–2013 in six urban sites in Western Australia, Australia (Chambers & Bencini 2015) found that underpasses, separated from roads by fencing, were used by mammals to cross the road. Southern brown bandicoots Isoodon obesulus fusciventer crossed 540 times, western grey kangaroos Macropus fuliginosus crossed 186 times and brushtail possums Trichosurus vulpecula crossed twice. Underpasses were also used by several invasive mammal species. Road crossings were monitored through 10 underpasses from May 2012 to May 2013, using camera traps. Underpasses were round (0.6–0.9 m diameter) or square culverts (0.6–1.2 m wide, 0.5–1.2 m high). They were 23–88 m long and separated from roads by 0.6–1.8-m-high fences. The time since construction ranged from two to 19 years.
