Studies of the distribution, assessment of the Snow leopard population, as well as the state of the populations of its main prey species, the impact of anthropogenic factors are the basis for the development of long-term and effective action plans and strategies for its conservation. To this end, we have carried out work on three different territories of the Mongolian Altai: Jargalant, Bumbat and Baatar Khairkhan Mountains. All three territories differ in the nature of the location in relation to other parts of the Snow leopard's range, and in the nature of the relief and economic use. The main method of research is the search and registration of traces of life activity of the Snow leopard and its main prey species (Mongolian marmot and Siberian ibex). For this purpose, we have passed 18 research routes with a total length of 197.5 km where we recorded all traces of the Snow leopard, Siberian ibex and Mongolian marmot life activities, as well as the distribution of the number of livestock. Another research method we have used is the application of camera traps. We installed 27 camera traps in total. As a result of their work we have obtained 51 photo location of the Snow leopard and identified at least 3 females, 2-3 adult males, 2-3 young individuals, the sex of which could not be established, including individuals aged about 2 years, 2 cubs. Both methods of research (search for traces of life activities and the application of camera traps) complement each other, and the correct use of camera traps can reduce the subjectivity of the results obtained by the search for traces of life activities. Thus, the reliability of the results is significantly increased. Our studies show that the largest number of traces of Snow leopard activity (the number of scrapes per 1 km of the route) and the largest number of photo locations were recorded in the central part of the Jargalant khairkhan mountain range-the territory that is the most remote and inaccessible for grazing livestock. In this territory, the highest frequency of Snow leopard presence was noted (20-40 scratches/km), and accordingly 5 from 11 identified snow leopards were registered. A similar pattern of distribution of traces of vital activity was registered for the other two territories.
The distribution of the snow leopard (Panthera uncia uncia (Shreber, 1775) across its geographic range is associated exclusively with the mountain landscapes. The most important factor in maintaining the integrity and viability of a population is its structure.Our studies were conducted in 2010, 2011 and 2012 and covered most of the range of snow leopard in East Kyrgyzstan. Each territory was surveyed through series of routes. The main methods used in field research were: searching for traces of vital activity, conducting short trail surveys, and using the SLIMS (Snow Leopard Information Management System) technique.In order to study the spatial structure of the snow leopard population, we conducted individual DNA-based identification and GPS registration of bioassays collected from all individuals inhabiting this territory. Biological samples (tissue, fur, and excrement) were obtained following the protocols for collecting bioassays. A total of 146 samples (2 of wool, 2 of tissue, and 142 of excrement) were collected in nature in the Central Tien Shan Mts within Kyrgyzstan (in the Sarychat-Ertash Reserve, and in the area of the Kainar River).Snow leopard DNA was identified in 70 samples. A total of 21 individual snow leopards (8 females and 13 males) were identified. All females of a local population of the Sarychat-Ertash Reserve, with the exception of one, were directly related to each other. The same is true for most of males (11 of 13). Two females were accompanied by kittens. All females settled near the maternal site, while almost all males, which were born there, move away. There is a direct correlation between population density and marking activity.
In 2011–2013, we surveyed the population structure, spatial distribution and the number of tigers in Southwestern Primorye (about 5000 km2). The total number of tigers, according to winter route census, DNA analysis and camera trapping was estimated at 24–25 adults and 6–7 cubs, belonging to four different litters. The location of tigers is mainly confined to areas difficult to access for people, and with a high density of ungulates. Tigers concentrated in the habitat strip bordering China, mainly comprising the 'Land of the Leopard' National Park. A few tiger tracks were recorded outside of protected areas and on hunting tenures. Current methods for estimating tiger numbers needs critical reflection. Winter census by tracks in the snow is often largely influenced by subjectivity. The main reason for this is the large number of surveyors of various degrees of qualification and as a result the conflicting interpretation of track identification. In our opinion, the most objective results are obtained from a consistent survey of the territory by a limited number of specialists and daily adjustments of collected materials. Precise and informative methods for determining the number and the structure of tiger populations are DNA analysis of biological samples combined with camera trap census. However, a number of significant drawbacks limits their widespread use: this method is labor-intensive and results in high project costs. In addition, weather conditions can greatly affect the preservation of DNA in the samples. There is a need to organize additional survey routes for installing camera traps and detecting of biological samples in order to register the tigresses with young, as they are behavior is often distinguished by a more secretive lifestyle. As a rule, female tigers with young avoid the main movement routes of adult tigers. These methods are expedient only in the smaller survey plots of model areas.
