Photo taken on Oct. 25, 2016 shows the information center of the Blue Mountains National Park in New South Wales state, Australia. Four percent of Australia's continent is protected for conservation, encompassed within just over 500 national parks, or some 28 million hectares of land. Most national parks are managed by Australia's state and territory governments -- states are responsible for land management under Australia's constitution -- though the Commonwealth Government looks after six national parks, the National Botanic Gardens and 58 individual marine reserves.
