This document discusses biodiversity conservation through the establishment of protected areas like national parks, wildlife refuges, biosphere reserves, and conservation corridors. It explains that national parks protect natural landscapes and species while prohibiting activities like grazing and cultivation. Wildlife refuges provide sanctuary for species from threats. Biosphere reserves integrate biodiversity conservation with sustainable development and include core protected zones surrounded by buffer and transition areas where limited human activities are permitted. Conservation corridors help share genetic information between protected populations.
