Australia has the unfortunate distinction of being the continent with the most mammalian extinctions in the past 200 hundred years. This reflects mostly the effects of widespread habitat loss and the introduction of non-native species. Sadly roadkill is also a contributor, threatening some wildlife populations (eg. Tasmanian devil) as well as risking human and vehicle damage. Roadkill also presents an unsightly aspect of Australia to visitors and lovers of nature, which can have a negative impact on tourism.
Animals may be killed as transportation networks encroach into wildlife habitat, either as roadkill or as boatstrike. In addition to the deleterious effects of wildlife populations, roadkill is often commented on as unsightly - after all, many visitors come to Australia to see native animals alive, not splattered all over the highway! Road ecology researchers are actively looking for ways to reduce roadkill. Methods include keeping animals off the road (odour repellents, reflectors), facilitating wildlife crossings (rope bridges, underpasses) and managing driver behaviour (signage, traffic calming devices).
Ultimately the most cost effective approach is for drivers to be alert and slow down for wildlife. Sadly, despite best efforts, wildlife-vehicle collisions can still occur - many dedicated volunteers donate time and resources to care of injured wildlife and it is prudent for all who travel in Australia to know what to do in such situations.
