The Foundation for National Parks & Wildlife has a simple mission - to create parks and save species. In creating parks, we work with State and Federal governments to identify potential land purchases, and then assist with funds to acquire that land. We don't hold any land - we pass it straight over to the Government to add to the National Park portfolio and it is then managed by the state rangers. In saving species, we work extensively with volunteers, scientists, governments, local communities and other organisations to deliver community-based conservation projects and research nation-wide, including developing corridors for native animals, connecting disparate groups of species to allow them to survive and thrive. Partnership is at the very heart of our philosophy and is central to everything we do.
