Australia has enormous problems with large invasive species like feral pigs, horses and deer. These species have negatively impacted huge sections of the continent. Yet self interest sometimes over rides the need to remove these populations. For instance, hunters sometimes argue that animals like deer should be left in wild places like national parks to allow continued hunting. And there is a huge campaign to see feral horse populations retained in the Australian Alps on spurious ‘cultural’ grounds.
Public debate has focused strongly on wild horse populations over the past few years. The threat poised by deer in lutruwita/ Tasmania is set to become a major public issue as the size of the feral deer population becomes clear. It is obvious that deer are moving into new habitats, and will bring enormous ecological impacts as they do so.
