In situ conservation involves protecting endangered species within their natural habitats. This may include protecting habitat areas, managing threats to species, and working with local communities. Key aspects of in situ conservation according to the document include establishing protected areas like national parks and wildlife sanctuaries, managing these areas under IUCN categories, and implementing projects to conserve specific species like tigers and elephants within their natural ranges. In situ conservation aims to maintain viable populations of all native species and prevent loss of biodiversity.
