The Southern Cardamom National Park connects older protections in and around the Greater Cardamom Mountains, effectively creating a so-called mega-protection totalling . The older protections include Phnom Samkos Wildlife Sanctuary, Central Cardamom Mountains and Phnom Aural Wildlife Sanctuary, covering the northern parts of the Cardamom Mountains, and Peam Krasop Wildlife Sanctuary, Botum Sakor National Park and Kirirom National Park, south of the park. In addition to safeguarding habitats and wildlife corridors for larger animals, a main purpose of the national park is to create a safe wildlife protection for reintroducing tigers to Cambodia. Tigers went extinct in Cambodia in 2007.
