Schaller, G. B., Jurang, R., & Mingjiang, Q. (1988). Status of snow leopard (Panthera-uncia) in Qinghai-Province and Gansu Province-China. Biological Conservation, 45(3), 179–194.
Abstract: The status and distribution of the snow leopard Panthera uncia was investigated in two provinces of China. The cats occur over about 65,000km2 or 9% of the Qinghai Province, and in a few places along the western edge of Gansu Province. In many areas the animals have in recent decades been decimated or locally eradicated, as have their prey. Counts of wild ungulates in 9 mountain block, totalling 1375km2, known for abundant wildlife, had an average of 1.4-5.4 animals km2, principally blue sheep Psuedois nayaur, which together with marmot Marmota himalayana, represent the snow leopards main prey. Possibly 650 snow leopards survive in Qinghai but shooting and trapping of this legally protected animal and the hunting of blue sheep for local consumtion and export threaten their existence.

Abstract: Study on the current status of large mammals species population was carried out in Khunjerab National Park, Northern Areas. The observation recorded showed that the population of Tibetan Red fox (Vulpes vulpes montana), Snow leopard (Uncia uncia), and Wolf (Canis lupus) have, though a bit, increased but are still in the rank of “Endangered”. While the population of Himalyan Ibex (Cpara ibex sibirica) is increasing more rapidly and their status is now “Common” in the Park. The limited population of Marcopolo sheep (Ovis ammon polii), Tibetan wild Ass (Equus hemionus kiang) and Brown bear (Urus arctos) is still under threat, and comes them under “Critical Endangered” category.

Abstract: China may hold a greater proportion of the global snow leopard Panthera uncia population than any other country, with the area of good quality suitable habitat, estimated at nearly 300,000 km2, comprising .50% of that available across the species' entire range. We can now reconfirm the presence of snow leopard in the Taxkurgan area of Xinjiang Province in north-west China after a period of 20 years.

Abstract: The snow leopard (Uncia uncial Schreber, 1776) is the most poorly studied species of the cat family in the world and, in particular, in Russia, where the northern periphery of the species area (no more than 3% of it) is located in the Altai-Hangai-Sayan range [1]. It is generally known that the existing data on the Russian part of the snow leopard population have never been a result of targeted studies; at best, they have been based on recording the traces of the snow leopard vital activity [2]. This is explained by the snow leopard's elusive behavior, inaccessibility of its habitats for humans, and its naturally small total numbers in the entire species area. All published data on the population status of the snow leopard in Russia, from the first descriptions of the species [3-6] to the latest studies [7, 8] are subjective, often speculative, and are not confirmed by
quantitative estimates. It is obvious, however, that every accurate observation of this animal is of particular interest [9]. The purpose of our study was to determine the structure and size of the population group presumably inhabiting the Western Sayan mountain ridge at the northern boundary of the species area

Wolf, M., & Ale, S. (2009). Signs at the Top: Habitat Features Influencing Snow Leopard Uncia Uncia Activity in Sagarmatha National Park, Nepal. Journal of Mammalogy, 90(3), 604–611.
Abstract: We used logistic regression to examine factors that affected the spatial distribution of sign (scrapes, feces, footprints, spray or scent marks, and rubbing sites) in a newly reestablished population of snow leopards (Uncia uncia) in Sagarmatha (Mount Everest) National Park, Nepal. Our results indicate that terrain and human activity were the most important factors determining the spatial distribution of leopard activity, whereas presence of their major prey species (Himalayan tahr [Hemitragus jemlahicus]) had only a moderate effect. This suggests that localities at which these animals are active represent a trade-off between suitable habitat and avoidance of potential risk from anthropogenic origins. However, the influence of prey presence was likely underestimated because of the methodology used, and likely weighed in the trade-off as well.

Abstract: The Snow leopard (Panthera uncia) is one of the most threatened wild big cats within its range of distribution, however, the question of its systematic status is a matter of debate. Is it a member of genus Panthera, or is it in its own genus (Uncia)? The analysis of genetic difference at the DNA level may provide useful data to clarify the issue. In the present study, ten hexanucleotide-specific restriction endonucleases were used to evaluate the patterns of mitochondrial DNA variation between the Snow leopard and leopard (P. pardus). The molecular size of mtDNA from the two species was about 16.5 kb. Ten enzymes surveyed 32-34 restriction sites, which corresponded to 192 apprx 204 base pairs, or 1.16% apprx 1.24% of the total mtDNA molecule. A total of 45 restriction sites were mapped; of these sites, twenty-four, which correspond to 53.3% of the total sites, were variable. The sequence divergence between them was 0.075 33, which was undoubtedly in the species-level distinction but did not reach the genus level. Therefore, the Snow leopard should be placed in the genus Panthera rather than in its own ganus. It also seems reasonable to recognize Uncia as a valid subgenus. This conclusion not only support but also supplement the viewpoint of Simpson who treated Uncia as a subgenus within Panthera.

Abstract: The snow leopard (Uncia uncia) is a very rare species in China. The survey of traces of snow leopard in Kunlun, Altay and Tianshan is them a instep of the Project of Snow Leopard in X injiang supported by the International Snow Leopard Trust ( SLT) and the Xinjiang Conservation Fund (XCF). During the field survey from 2004 to 2010, the Xinjiang Snow Leopard Group ( XSLG) spent about 270 days in over 20 different places, covering over 150 transects totaling nearly 190 km, and found 1- 3 traces per kilometer. The traces of snow leopard recorded include dung, odor, chains of footprints, scraping, paw nail marks, lying mark, fur, urine, bloodstain, leftover of prey corpse, roaring and others. Based on tracer image analyses, the XSLG got to know primarily scopes of the domains, distribution and relative density of the snow leopard in these areas. Then the group began to take infrared photos, conducted survey of food sources of the leopards, investigated fur market and paths of trading, and cases of killing, and carry out civil survey through questionnaire, non government organization community service and research on conflicts between grazing and wild life protection. A total of 36 infrared came ras were laid out, working a total of about 2 094 days or 50 256 hours. A total 71 rolls of film were collected and developed, includ ing 32 clear pictures of snow leopards, thus making up a shooting rate or capture rate of 1.53%. It was ascertained that in Tomur Peak area, there were 5- 8 snow leopards roaming within a range of 250 km2, forming a population density of 2��0- 3��2 per 100 km2. After compar ing the various monitoring results, the advantages and limitations of different monitoring methods have been discussed.

Abstract: Sightings of snow leopards Uncia uncia in the wild are rare. This is because snow leopards occur in low numbers and are very elusive (Schaller 1977). Snow leopards may be sparsely distributed,but they may not, however, be very elusive in the world's highest park, Sagarmatha (Mt. Everest) National Park (86° 30' 53“ E to 86° 99' 08” E and 27° 46' 19“ N to 27° 06' 45” N) in Nepal.

Abstract: Letter to Nature Editor, in response to: In their plea for bringing Pleistocene wildlife to the New World (“Re-wilding North America” Nature 436, 913–914; 2005), Josh Donlan and colleagues do not discuss successful efforts to ensure long-term survival of large carnivores in Africa and Asia. A few examples are given.
