Singh, R., Krausman, P. R., Pandey, P., Maheshwari, A., Rawal,
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.

Conservation and climate change: Assessing the vulnerability of snow leopard habitat to treeline shift in the Himalaya. Biological Conservation, 150, 129–135.
Abstract: Climate change is likely to affect the persistence of large, space-requiring species through habitat shifts,
loss, and fragmentation. Anthropogenic land and resource use changes related to climate change can also
impact the survival of wildlife. Thus, climate change has to be integrated into biodiversity conservation
plans. We developed a hybrid approach to climate-adaptive conservation landscape planning for snow
leopards in the Himalayan Mountains. We first mapped current snow leopard habitat using a mechanistic
approach that incorporated field-based data, and then combined it with a climate impact model using a
correlative approach. For the latter, we used statistical methods to test hypotheses about climatic drivers
of treeline in the Himalaya and its potential response to climate change under three IPCC greenhouse gas
emissions scenarios. We then assessed how change in treeline might affect the distribution of snow leopard
habitat. Results indicate that about 30% of snow leopard habitat in the Himalaya may be lost due to a
shifting treeline and consequent shrinking of the alpine zone, mostly along the southern edge of the range
and in river valleys. But, a considerable amount of snow leopard habitat and linkages are likely to remain
resilient to climate change, and these should be secured. This is because, as the area of snow leopard habitat
fragments and shrinks, threats such as livestock grazing, retaliatory killing, and medicinal plant collection
can intensify. We propose this approach for landscape conservation planning for other species
with extensive spatial requirements that can also be umbrella species for overall biodiversity.

Izold, J. (2008). Snow Leopard Enterprise: a conservation project that saves an endangered species and supports needy families. Anim.Keepers' Forum, 9(5), 359–364.
Abstract: The World Conservation Union listed the snow leopard (Uncia uncia) as endangered in 1974. With as few as 3,500 snow leopards left in the wild, scientists placed the snow leopard on the IUCN Red List of critically endangered species shared by animals such as the giant panda and tiger. In an effort to save the snow leopard from extinction, former zoo employee Helen Freeman founded the Snow Leopard Trust in 1981. The Snow Leopard Trust works to save this elusive cat by incorporating community-based conservation projects. One of these project Leopard Enterprise (SLE), impacts poverty stricken communities in Mongolia, Kyrgyz Republic, and Pakistan. It assists over 300 families in its conservation efforts. The economic incentives provided via SLE have led participating communities not to harm the snow leopard or its prey, and to practice sustainable herding. Since the project began in 1997, the number of snow leopards harmed around the communities' territories has dropped to near zero. Additionally, the annual income of families that utilize the benefits of SLE has increased by 25% to 40%. SLE creates this economic benefit by providing the training and equipment necessary to make desirable products from the wool of herd animals. Snow Leopard Trust then purchases these handicraft items from the local people and them globally. Zoos can expand their conservation efforts by simply offering these items in their gift shops. Woodland Park Zoo (WPZ) was the first zoological institution to sell the products, and WPZ continues to generate revenue from them. SLE is a golden opportunity for zoos to increase revenue, assist poor families, and save an endangered species and fragile ecosystem.

Guerrero, D. (1998). Animal behavior concerns & solutions: snow leopard (Uncia uncia) evaluation, zoo. Anim.Keepers' Forum, 25(2), 56–58.
Abstract: The author offers advice on how a captive-raised snow leopard cub could be acclimated to humans so it could be used as a zoo “ambassador”. The cub had negative experiences with humans and lacked socialization with other animals and conspecifics. Methods of avoiding and redirecting the cub's aggressive behavior are suggested. lgh.

Sloane, A., Kelly, C., McDavitt, S., & Marples, N. (1998). Big cats in captivity: a quantitative analysis of enrichment. Adv.Etho, 33, 43.
Abstract: Studies on three species of big cats at Dublin Zoo have led to firm conclusions about the effects of certain forms of enrichment, some of which will be presented here. Lions, jaguars, and snow leopards were studied over two years and their behaviours quantified using focal animal sampling during selected hours during daylight. By comparison of these activity budgets with and without the enrichments being present, it was possible to identify the exact behavioural changes caused by each enrichment method, and to quantify these changes. In this contribution we present results showing that the presence of a platform in both lion and jaguar enclosures dramatically reduced stereotypic pacing behaviour. We will demonstrate that the effects of short term enrichment devices may have a wide range of effects on behaviours which outlast the presence of the stimulus. For instance scents added to the cage, or food/play items such as horse hides, hidden fish or ice-blocks often reduce pacing and increase resting later in the day, even after the cats have ceased using the enrichment items. This reduction in pacing and increase in resting time often meant that the amount of the enclosure used per hour was actually reduced with the presence of new stimuli, as result opposite to what might have been expected. The results of these studies will be discussed in relation to effective animal management.

Kovshar A.F. (2001). About the necessity to alter the border of Aksu Jabagly nature reserve (Vol. Vol. 8.).
Abstract: An extension of the Aksu Jabagly nature reserve is suggested in order to improve effectiveness of rare and endemic species conservation in the West Tien Shan. The existing area of the nature reserve is large enough for conservation and reproduction of most of the large mammal species such as ibex, bear, wild boar, snow leopard; the area is however insufficient for species such as Tien Shan argali, roe-deer, whose seasonal migrations extend beyond the area of the nature reserve, as well as Menzbier's marmot a rare endemic to the West Tien Shan, whose habitat is situated 10 15 km from the nature reserve.

Abstract: After 30 years of searching for the mysterious Beringian snow cat in vast space of Koryakia and Chukotka
one of the five cameras recorded finally this beast at night in September 2014. This is not so much a
sensation as a real scientific discovery, saying that the hearts of the snow leopard population resettlement are
not in 5000 km from the main range boundaries, but much closer. Where? � will show further studies.
In addition to the snow leopard in the North-Eastern Asia, it found two more endangered large
mammal species: the Amur tiger and the relict of the Ice Age � the Irkuyem-bear. Author has given these
animals his life and his article devoted to this topic.

Abstract: The International Snow Leopard Trust (ISLT) is a nonprofit environmental organization dedicated to the conservation of the endangered snow leopard and its mountain ecosystem through a balanced approach that considers the needs of the local people and the environment. As such, we wish to stress that the ISLT does not have a position regarding the present conflict in Afghanistan. However, this organization believes that there are important repercussions regarding this conflict that have yet to be addressed in the media, within government circles, or among the public. This report documents some of these repercussions so that they may be included in the present dialog.

Pokrovskiy V.S. (1969). Mammals.
Abstract: The work presents a preliminary list of rare and endangered predatory and ungulate species. Snow leopard inhabits the mountain ridges of Tajikistan and Kyrgyzstan, and sometimes is met in the Altai and Tuva. Despite its habitat has not changed since recently, number of snow leopard is decreasing. Snow leopard population is reducing because this species is believed to be dangerous, as its skin is of high and sustainable demand, and because of high prices zoos will readily pay to buy snow leopards. Shepherds, local hunters and geologists hunt snow leopard.

Theile, S. (2003). Fading Footprints: The Killing and Trade of Snow Leopards. Caimbridge, UK: Traffic International.
Abstract: Snow Leopards, in a genus of their own, are endangered big cats. They inhabit rugged,
mountainous terrain, in 12 range States – Afghanistan, Bhutan, China, India, Kazakhstan,
Kyrgyzstan, Mongolia, Nepal, Pakistan, the Russian Federation, Tajikistan and Uzbekistan.
There are regional differences in prey, but the cats' natural prey includes ungulates and rodents.
The global population of Snow Leopards is estimated to be between about 4000 and 7000, but
sharp declines in populations have been reported over the past decade from parts of the species's
range. High levels of hunting for the animals' skins and for live animals, for zoos, during the
last century contributed to the species's endangered status and, from the 1970s, legal measures
were taken for its protection. In 1975, the species was listed in Appendix I of CITES (the
Convention on International Trade in Endangered Species of Fauna and Flora) and in 1985 it
became an Appendix-I species of the Convention of Migratory Species. It has been accorded
nation-wide legal protection in almost every range State, in some cases since the 1970s. In spite
of such provision, Snow Leopards have been hunted during the 1990s in numbers as high as at
any time in the past and this killing continues in the present century. This report details the status of illegal poaching and trade in snow leopards in the late twentieth and early twenty-first centuries.

Abstract: An attempt of analyzing the role of Uzbekistan' nature reserves in conservation of gene pool of the rare and endangered terrene vertebrate fauna is done. Of 21 rare vertebrate species, 11 mammal species, eight nesting bird species and two reptile species were detected to inhabit seven nature reserves. This makes up 36.2 percent within the total number of species included in the Red Data Book of the Uzbek SSR or 3.7 percent of the country's fauna. Single snow leopards were found in the Chatkal and Hissar nature reserves. Data of the species inhabiting the Zaamin nature reserve needs to be verified.

Ale S. (2005). Have snow leopards made a comeback to the Everest region of Nepal?.
Abstract: In the 1960s, the endangered snow leopard was locally extirpated from the Sagarmatha (Mt. Everest) region of Nepal. In this Sherpa-inhabited high Himalaya, the flourishing tourism since the ascent of Mt Everest in 1953, has caused both prosperity and adverse impacts, the concern that catalyzed the establishment of Mt. Everest National Park in the region in 1976. In the late 1980s, there were reports that some transient snow leopards may have visited the area from adjoining Tibet, but no biological surveys exist to confirm the status of the cats and their prey. Have snow leopards finally returned to the top of the world? Exploring this question was the main purpose of this research project. We systematically walked altogether 24 sign transects covering over 13 km in length in three valleys, i.e. Namche, Phortse and Gokyo, of the park, and counted several snow leopard signs. The results indicated that snow leopards have made a comeback in the park in response to decades of protective measures, the virtual cessation of hunting and the recovery of the Himalayan tahr which is snow leopard's prey. The average sign density (4.2 signs/km and 2.5 sign sites/km) was comparable to that reported from other parts of the cats' range in the Himalaya. On this basis, we estimated the cat density in the Everest region between 1 to 3 cats per 100 sq km, a figure that was supported by different sets of pugmarks and actual sightings of snow leopards in the 60 km2 sample survey area. In the study area, tahr population had a low reproductive rate (e.g. kids-to-females ratio, 0.1, in Namche). Since predators can influence the size and the structure of prey species populations through mortality and through non-lethal effects or predation risk, snow leopards could have been the cause of the population dynamics of tahr in Sagarmtha, but this study could not confirm this speculation for which further probing may be required.
