R. S., Sharma, S., Shekhar, S. (2020). Predicting Habitat Suitability of Snow Leopards in the Western
Himalayan Mountains, India. Biology bulletin, 47(6), 655–664.
Abstract: The population of snow leopard (Panthera uncia) is declining
across their range, due to poaching, habitat fragmentation, retaliatory
killing, and a decrease of wild prey species. Obtaining information on
rare and cryptic predators living in remote and rugged terrain is
important for making conservation and management strategies. We used the
Maximum Entropy (MaxEnt) ecological niche modeling framework to predict
the potential habitat of snow leopards across the western Himalayan
region, India. The model was developed using 34 spatial species
occurrence points in the western Himalaya, and 26 parameters including,
prey species distribution, temperature, precipitation, land use and land
cover (LULC), slope, aspect, terrain ruggedness and altitude. Thirteen
variables contributed 98.6% towards predicting the distribution of snow
leopards. The area under the curve (AUC) score was high (0.994) for the
training data from our model, which indicates pre- dictive ability of
the model. The model predicted that there was 42432 km2 of potential
habitat for snow leop- ards in the western Himalaya region. Protected
status was available for 11247 km2 (26.5%), but the other 31185 km2
(73.5%) of potential habitat did not have any protected status. Thus,
our approach is useful for predicting the distribution and suitable
habitats and can focus field surveys in selected areas to save
resources, increase survey success, and improve conservation efforts for
snow leopards.

Jackson, R., Hunter, D.O. (1995). Snow leopard Survey and conservation handbook (First edition).
Abstract: The objectives of this handbook (First edition) are to provide standard procedures for conducting snow leopard status and distribution surveys; suggest uniform methods for assessing the status and relative abundance of large prey species (ungulates such as blue sheep, argali, markhor, Himalayan tahr, urial, ibex, red deer, and roe deer); offer guidance in evaluating habitat quality and identifying the major environmental factors affecting species welfare; and provide standard forms for reporting the results of these field surveys, and a process for feeding information developed by the International Snow Leopard Trust into Snoe Leopard Information Management System (SLIMS).

Formozov A.N. (1989). Tiger. Leopard. Snow Leopard.
Abstract: The number of large cats is reducing. These animals are hold out in the most difficult of access places. During long time snow leopard was a poorly known animal. The situation was changed with developing of mountain tourism and mountaineering. It's necessary to reduce the capturing snow leopards for zoological gardens.

Abdusalamov I.A. (2001). Required protection measures for rare and endangered vertebrate species in Tajikistan (Vol. N 2 (143)).
Abstract: The network of Tajikistan's protected areas (four nature reserves, 14 national and 18 regional sanctuaries, one national park) is described. The establishment of `Shakhristan state complex nature reserve' and `Sarykamish state complex reserve', and interstate nature complex park on northern slope of the Turkestan ridge is recommended to improve conservation practices for a number of endangered vertebrate animal species in Northern Tajikistan (such as brown bear, snow leopard, wild sheep, and others).

(1998). Biological diversity conservation. National strategy and action plan of the Republic of Uzbekistan.
Abstract: The National strategy and action plan of the Republic of Uzbekistan was signed on April 1, 1998. Snow leopard was included in the list of rare and endangered animal species and referred to category 2 a rare, not endangered species. It is distributed in highlands of the West Tien Shan and Pamiro-Alay. Its population is 30-50 animals. Snow leopard is protected in the Chatkal, Gissar nature reserve, and Ugam-Chatkal national park.

Koshkarev E.P. (1990). Key areas of snow leopard's habitat as main conservation objects (Vol. Part. 1.).
Abstract: The most vulnerable key areas within the snow leopard habitat are East Kazakhstan (an area of 48,000 square km) with no protected areas network established, and South Siberia (131,000 square km), where snow leopard is protected in three nature reserves. These areas are distant from main part of the habitat, isolated and have more extreme conditions. In Central Asia's key area (213,000 square km) linked to a main Chinese-Afghani part of the habitat, snow leopard was found in 11 nature reserves and two national parks. For reliable protection of this species it would be expedient to strengthen the role of the mountain nature reserves by means of extension and amalgamation of the areas, and other measures.

Baryshnikov G.F. (1981). Sub-genus Panthera Oken, 1816. Genus Panthera.
Abstract: The monograph provides taxonomic description of sub-genus Panthera Oken, 1816, genus Uncia grey, 1854. Snow leopard inhabits the mountains of Tajikistan, the Pamirs, Tien Shan, Tarbagatai, the Altai, the Sayans; also the mountain of Mongolia, Tibet, the Himalayas, and Hindukush, where it keeps to alpine meadows and woodless rocks at up to 3,000 – 4,000 m above sea level in summer, and descends to a lower elevation in winter. It described from the Altai. They are of minor trade importance. This species is rare all over its habitat and included in the Red Data Book of the USSR.

Sapozhnikov G.N. (1976). Wild sheep in Tajikistan.
Abstract: The monograph provides data concerning taxonomy, morphology, and age variability of wild sheep. There described distribution, number, population composition, behavioral patterns, reproduction, predators and parasites. Besides, a matter of conservation and sustainable use of the species is discussed. Together with wolf, snow leopard is called an enemy of O. o. vignei and argali (O. o. polii).

Marma B.B.and Yunchis V.V. (1968). A contribution to biology of the Snow-leopard (Panthera uncia uncia) (by observations in captivity) (Vol. XLVII, issue 11.).
Abstract: The methods to obtain the progeny of the snow leopard (Panthera uncia uncia) in captivity were being elaborated in the zoological garden of Kaunas, Lithuanian SSR. The blood characteristics for snow leopards is given and compared to that for African lions and Sumatrian tigers. A series of internal, external and clinical indices is established. The rat lasts for 5-7 day, the duration of pregnancy equals 98 days. The duration of lactation varies from 3 to 4 months. Sexual maturity is attained on the 3rd-4th year. From 1960 to 1967 in zoological garden of the world about 29 snow leopards were born, 14 of them in the Kaunas zoological garden.
