Highway underpasses for wildlife are working

New research Southern Cross University provides compelling evidence that road underpasses can lessen the impact of highway upgrades on Australia’s native wildlife populations. The study also allayed concerns that predators, particularly introduced feral pests, use underpasses as a prey-trap, at least by the observations at these locations. Wildlife cameras detected more than 4,800 medium-to-large mammals and goannas using highway underpasses located at Port Macquarie and Grafton over a two-year period. Species such as eastern grey kangaroos, swamp wallabies, red-necked wallabies, red-necked pademelons and lace monitors crossed some underpasses more than once per week. Rufous bettongs and echidnas crossed individual underpasses every two to four weeks.
