Abstract: Camera trapping is the most widely used data collection method for estimating snow leopard (Panthera uncia) abundance; however, the accuracy of this method is limited by human observer errors from misclassifying individuals in camera trap images. We evaluated the extent Whiskerbook (www.whiskerbook.org), an artificial intelligence (AI) software, could reduce this error rate and enhance the accuracy of capture-recapture abundance estimates. Using 439 images of 34 captive snow leopard individuals, classification was performed by five observers with prior experience in individual snow leopard ID (“experts”) and five observers with no such experience (“novices”). The “expert” observers classified 35 out of 34 snow leopard individuals, on average erroneously splitting one individual into two, thus resulting in a higher number than true individuals. The success rate of experts was 90 %, with less than a 3 % error in estimating the population size in capture-recapture modeling. However, the “novice” observers successfully matched 71 % of encounters, recognizing 25 out of 34 individuals, underestimating the population by 25 %. It was found that expert observers significantly outperformed novice observers, making statistically fewer errors (Mann Whitney U test P = 0.01) and finding the true number of individuals (P = 0.01). These differences were contrasted with a previous study by Johansson et al. 2020, using the same subset of 16 individuals from European zoos. With the help of AI and the Whiskerbook platform, “experts” were able to match 87 % of encounters and identify 15 out of 16 individuals, with modeled estimates of 16 ± 1 individuals. In contrast, “novices” were 63 % accurate in matching encounters and identified 12 out of 16 individuals, modeling 12 ± 1 individuals that underestimated the population size by 12 %. When comparing the performance of observers using AI and the Whiskerbook platform to observers performing the tasks manually, we found that observers using Whiskerbook made significantly fewer errors in splitting one individual into two (P = 0.04). However, there were also a significantly higher number of combination errors, where two individuals were combined into one (P = 0.01). Specifically, combination errors were found to be made by “novices” (P = 0.04). Although AI benefited both expert and novice observers, expert observers outperformed novices. Our results suggest that AI effectively reduced the misclassification of individual snow leopards in camera trap studies, improving abundance estimates. However, even with AI support, expert observers were needed to obtain the most accurate estimates.

Abstract: Parasites diversity in close-related species of hosts may be different depending on habitat use and climatic conditions. The aim of this study was to
analyze parasites fauna in four felid species inhabiting Russian Far East and South Siberia (including taiga forest and mountain treeless areas). We
have collected 272 feces samples of four felid species: Amur tiger, Amur leopard, snow leopard and Pallas� cat. Helminths (eggs and larvae) in
excrements were studied by flotation using a saturated solution of ammonium nitrate. We have described 10 helminths species in Amur tiger feces, 6
� in Amur leopard, 2 � in snow leopard and 3 � in Pallas� cat. Obviously, snow leopard and Palls� cat had lower helminths diversity than two other
species. These differences can be explained, to some extent, by climatic parameters. The climate in the snow leopard and Pallas' cat habitats is
described by sharp and significant temperature fluctuations – the annual temperature difference can exceed 90°C, which may lead to lower survival of
the number of infectious agents in Pallas' cat excrements. In addition, the snow cover that can protect helminth eggs and larvae from the cold
temperatures especially in Amur tiger and Amur leopard habitats. Possibly, another important factor is the spatial and social organization of Pallas'
cats, with a low frequency of contacts with other individuals. Such way, species-specific differences in helminths were related, probably, with the
species evolution in different habitats

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.

Abstract: Livestock depredation is an increasingly contentious issue across the range of the
endangered snow leopard (Uncia uncia). Depredation is most severe in or near protected areas
offering core habitat for this cat. “Surplus killing,” in which as many as 100 sheep and goats have
been killed in a single night, inevitably results in attempts at retaliatory killing of predators by
herders suffering significant loss. Ironically, such predation by snow leopard, wolf, or lynx can be
avoided by adequately predator-proofing nighttime enclosures. Predation on the open range is far
more difficult to address, but may be reduced to acceptable levels through improved day-time
guarding of livestock, educating herders on the importance of protecting the predator's natural prey
base, and by providing economic incentives to help offset unavoidable loss.
This paper describes community-based initiatives being undertaken in India's Hemis National Park
aimed at predator-proofing livestock corrals and encouraging local herders to become more effective
stewards of the snow leopard, its prey and habitat. A highly participatory, 4-step process known as
Appreciative Participatory Planning and Action (APPA) provides the primary mechanism for
assisting communities to develop Action Plans to reduce livestock depredation losses, increase
household incomes, and strengthen environmental stewardship. Herders are informed about the
Snow Leopard Stewardship program and conditions for a successful outcome. The team, comprised
of local people, NGO staff, facilitators and government officials, first identifies the root causes for
depredation (Discovery). Under the next phase, Dreaming, participants envision how their village
might appear if depredation losses were reduced to acceptable levels, household incomes increased,
and snow leopards fully protected. This provides a good basis upon which to collaboratively devise
actions for addressing the community's concerns (Design). Delivery involves implementing actions
under the overall Action Plan, as well as specific measures that can be acted upon immediately. The
community is encouraged to use simple but realistic indicators for monitoring the project's
effectiveness.
In Lessons Learned to Date, we highlight the importance of providing meaningful community
involvement from inception through project implementation and monitoring. The use of _APPA
_greatly increases ownership, communal empowerment and self-reliance, and local people's
willingness to protect wildlife. The Snow Leopard Conservancy believes that the most effective
conservation actions will be contingent upon (1) establishing direct linkages with biodiversity
protection; (2) ensuring reciprocal co-financing and commensurate responsibility from the
community; (3) encouraging full participation from all stakeholders irrespective of their gender, age
or economic status; and (4) ensuring regular monitoring and evaluation under an agreed-to Action
Plan that sets forth the responsibilities, contributions and obligations of each partner.
