Chapter 5.2 of Conservation Biology discusses methods for protecting biodiversity and natural resources. It covers legal protections for endangered species under acts like the U.S. Endangered Species Act and CITES. It also discusses preserving habitats through national parks and habitat corridors. Sustainable use programs aim to enable resource use while maintaining ecosystems. Reintroduction and species preservation programs work to save species like the California condor and black-footed ferret. Some species exist only in captivity.
