This article brings some information about 4 ungulate species (Przewalski's horses, dziggetay, bactrian camel and goitered gazelle) living in the B-zone of the Mongolian Gobi National Park. Przewalski's horses were reintroduced to this area in the 90s. Dziggetay (Equus hemionus hemionus) lives in the B-zone approximately in the number of 1,000 individuals. In the steppe or semidesert, we usually met lonely animals or small groups of 5-7 animals. No individual is bred in captivity. Bactrian camel (Camelus ferus bactrianus) living in this area is close by its habitus to the wild form which is living in the A-zone in the number of approx. 300 individuals. Goitered gazelle inhabits very diverse biotope in the B-zone: stipa steppes, saxaul semideserts as well as salt licks. The population in the Altay Gobi belongs to the subspecies of Djungarian goitered gazelle (Gazella subgutturosa sairensis), which is not bred in the zoological gardens. Dziggetay and goitered gazelle are listed in the Mongolian Red Book as rare.
