Abstract: The Red Book of the Kazakh SSR includes 91 rare and endangered vertebrate animal species: 30 mammal, 48 bird, eight reptile, one amphibian, and four fish species. 26 species (Menzbier's marmot, marten species, lynx, snow leopard, and other species) became rare because of a direct anthropogenic pressure. The prohibition of hunting, conservation and rehabilitation of their habitats, reproduction in enclosures and preservation of some species' genomes is a way that would conserve rare species, the authors believe.
