National Parks, World Heritage Areas and other parts of the conservation estate are not simply handed to the community by governments. Wild areas are hard fought for, sometimes for decades, before they gain protection. But once created, that is not the end of the story. Traditionally parks can face a range of problems and pressures, including under funding and over use, and invasion by feral species. In recent years it has become ever more apparent that climate change poses a huge threat to most ecosystems in the country, and hence the integrity of our national parks.
They are sometimes also threatened by proposals for commercial development. The following summary of current threats to national parks in Victoria comes from Phil Ingamells.
