Esipov A.V. (2003). Snow Leopard (Irbis) (Vol. Vol. II. Animals.).
Abstract: Critically Endangered l (CR C2a(i); D), locally distributed western subspecies of Central Asian species. It occurs in Western Tien Shan and Western Pamir Alay. It inhabits middle and high belts of the mountains. It prefers watersheds and rocky talus slopes. It never was numerous; last decades the numbers have been decreasing. In 1980's-1990's in Hissar nature reserve 5-11 individuals were counted, in 1970's-1980's in Chatkal nature reserve the 1-3 specimens were observed. Perhaps, total number is 20-30 individuals. The threats are development of high mountain pastures, decreasing of prey numbers, human persecution and poaching. Included in the IUCN Red List [EN] and in Appendix I of CITES.

Abstract: Data about distribution of stone marten, ermine, weasel, badger, bear, wolf, fox, and snow leopard in the Chatkal nature reserve is provided. In Tien Shan, snow leopard is not a rare species, and even a rather common species in some places. In the nature reserve, snow leopard was observed near the mountain Kurgan-Tash in 1948.

Abstract: Data on distribution, number, diet and breeding of snow leopard in NW spurs of the Hissar Ridge were collected over long-term studies in the span from 1981 to 1994. An increase in the number of this animal from 4 to 17 individuals has been recorded in the Hissar Nature Reserve (Uzbekistan).

Suryawanshi, K. R. (2009). Towards snow leopard prey recovery: understanding the resource use strategies and demographic responses of bharal Pseudois nayaur to livestock grazing and removal; Final project report.
Abstract: Decline of wild prey populations in the Himalayan region, largely due to competition with livestock, has been identified as one of the main threats to the snow leopard Uncia uncia. Studies show that bharal Pseudois nayaur diet is dominated by graminoids during summer, but the proportion of graminoids declines in winter. We explore the causes for the decline of graminoids from bharal winter diet and resulting implications for bharal conservation. We test the predictions generated by two alternative hypotheses, (H1) low graminoid availability caused by livestock grazing during winter causes bharal to include browse in their diet, and, (H2) bharal include browse, with relatively higher nutrition, to compensate for the poor quality of graminoids during winter. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. Graminoid quality in winter was relatively lower than that of browse, but the difference was not statistically significant. Bharal diet was dominated by graminoids in areas with highest graminoid availability. Graminoid contribution to bharal diet declined monotonically with a decline in graminoid availability. Bharal young to female ratio was three times higher in areas with high graminoid availability than areas with low graminoid availability. No starvation-related adult mortalities were observed in any of the areas. Composition of bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Since livestock grazing reduces graminoid availability, creation of livestock free areas is necessary for conservation of grazing species such as the bharal and its predators such as the endangered snow leopard in the Trans-Himalaya.

Weiskopf, S. R., Kachel, S. M., McCarthy, K. P. (2016). What Are Snow Leopards Really Eating? Identifying Bias in Food-Habit Studies. Wildlife Society Bulletin, , 1–8.
Abstract: Declining prey populations are widely recognized as a primary threat to snow leopard (Panthera
uncia) populations throughout their range. Effective snow leopard conservation will depend upon reliable
knowledge of food habits. Unfortunately, past food-habit studies may be biased by inclusion of nontarget
species in fecal analysis, potentially misinforming managers about snow leopard prey requirements.
Differentiation between snow leopard and sympatric carnivore scat is now cost-effective and reliable using
genetics. We used fecal mitochondrial DNA sequencing to identify scat depositors and assessment bias in
snow leopard food-habit studies. We compared presumed, via field identification, and genetically confirmed
snow leopard scats collected during 2005 and 2012 from 4 sites in Central Asia, using standard forensic
microscopy to identify prey species. Field identification success varied across study sites, ranging from 21% to
64% genetically confirmed snow leopard scats. Our results confirm the importance of large ungulate prey for
snow leopards. Studies that fail to account for potentially commonplace misidentification of snow leopard
scat may mistakenly include a large percentage of scats originating from other carnivores and report
inaccurate dietary assessments. Relying on field identification of scats led to overestimation of percent
occurrence, biomass, and number of small mammals consumed, but underestimated values of these measures for large ungulates in snow leopard diet. This clarification suggests that the conservation value of secondary prey, such as marmots (Marmota spp.) and other small mammals, may be overstated in the literature; stable snow leopard populations are perhaps more reliant upon large ungulate prey than previously understood.

Taryannikov V.I. (1986). Distribution, biology, and current population status of rare predatory mammals in the Western Hissar.
Abstract: Described are distribution, biotopical distribution, food, and some biological features of Uncia uncia, Felis lynx, Lutra lutra. New finds of Lutra lutra were observed at the Kashkadarya river. All the species' populations were counted and the reasons for their decrease given. In the author's opinion, number of snow leopard is decreasing as number of Siberian ibex is decreasing too and snow leopard is being poached for. There are 10-12 snow leopards on the slopes of the Hissar ridge.
