On land set aside for nature conservation, excessive levels of herbivore grazing pressure can have negative impacts on biodiversity, and active management of total grazing pressure can be required to facilitate ecological restoration. Experience from the Flinders Ranges National Park in South Australia shows that complete removal of domestic stock, and effective management of feral herbivores (e.g. rabbits, goats), will not necessarily result in improvements to land condition (Alexander 1997). In these situations, reduction of kangaroo populations can also be required to meet restoration objectives.
Two species of large kangaroo (Western Grey Kangaroo, Macropus fuliginosus and Euro, M. robustus) are currently being culled as a component of ecological restoration programs on three conservation reserves in South Australia: Flinders Ranges National Park, Coffin Bay National Park and Para Wirra Recreation Park. All three reserves have integrated control programs for feral herbivores, and vegetation monitoring programs that suggest kangaroo grazing pressure is negatively impacting on native vegetation.
