Author: Li, X., Wei, C., Chen, X., Jia, D., Li, P., Liang, S., Jikmed, A., Gao, Y., Zhao, X., Chu, M., Sharma, K., Alexander, J. A., Lu, Z., Xiao, L.

Abstract: Abundance estimation of large carnivores is essential for their effective conservation planning, yet estimating population size is challenging due to their elusive and wide-ranging nature. China is estimated to encompass 60% of the snow leopard Panthera uncia habitat, making it a crucial pillar for global snow leopard conservation. However, no large-scale population assessment has been conducted despite scattered survey effort accumulating rapidly in recent years. This study combined and standardized existing camera trap survey data from 12 sites collected by four organizations during 2015 ~ 2021 to estimate snow leopard population in an area of 360,000 ­ km2 on the Tibetan Plateau, China. The representativeness of existing survey was evaluated based on two habitat stratification approaches to achieve less biased population assessment. Spatially explicit capture-recapture (SECR) models were applied for snow leopard density estimation and the top-ranked model showed a significant positive correlation between conservation priority strata and density. An average snow leopard density of 0.90 /100 ­ km2 (95% CI: 0.68 ~ 1.21 /100 ­ km2) and a population size of 1,002 (95% CI: 755 ~ 1,341) individuals was estimated for the defined snow leopard habitat. Two more conservative estimates of 971 (95% CI: 732 ~ 1,287) and 978 (95% CI: 737 ~ 1,267) individuals were generated within two defined survey regions, in which our data had higher representativity. This study presents a practical approach to synthesize existing population survey data for large-scale population assessments of individually identifiable species. The estimated number represents 11 ~ 21% of the global snow leopard population, indicating high conservation value of this region.

Title: Who’s the boss? Understanding the spatial relationship between snow leopard and Eurasian lynx in southern Mongolia

Author: Byambasuren, C., Johansson, O., Alexander, J. S., Lkhagvajav, P., Samelius, G., Sharma, K.

Abstract: Interspecific competition, a fundamental ecological process characterized by negative interactions between species, plays a vital role in shaping ecological communities. Despite the co-occurrence of the snow leopard Panthera uncia and the Eurasian lynx Lynx lynx across vast landscapes in Asia, their interactions remain poorly understood. In this study, we investigated how the presence of snow leopards affected site-use by lynx and whether the presence of snow leopards resulted in behavioral adaptations by the lynx. Between 2017 and 2022, we conducted camera trap-based surveys across six sites in southern Mongolia and evaluated species co-occurrence by snow leopards and lynx using the occupancy framework. We assumed snow leopards to be the dominant species while using topographical and land cover variables as covariates. Our results show that the presence of snow leopards influenced site-use by lynx, leading to a shift in space use when snow leopards were present. Specifically, lynx used the entire range of ruggedness and did not select for shrubby areas in the absence of snow leopards, whereas they avoided rugged areas and had a strong preference for shrubby areas when snow leopards were present. Our findings emphasize the influence a larger predator can have on the space use of a smaller predator, and how the presence of snow leopards can alter the space-use of lynx. Understanding these interactions  and behavioral adaptations can be useful for developing effective conservation strategies in the region.

Title: Reflections from a snow leopard eco-camp program in Mongolia

Author: Mijiddorj, T. N., Ganchudur, B., Samelius, G., Alexander, J. S.

Abstract: Environmental education can efficiently engage individuals in addressing environmental challenges and promote collaboration among stakeholders. The aim of this paper was to understand how children participating in eco-camps perceived nature and the environment. Additionally, we aim to share our experiences from eight years of eco-camp activities conducted for sixth-grade students (aged 12-13 years) in the Gobi region of southern Mongolia. The program utilized active learning in snow leopard habitats. We used creative expressions, specifically write-ups such as poems, to capture the children’s perceptions and feelings about nature. The findings revealed that the children participating in the program conveyed a sense of awe for nature and awareness of ecosystem services. Feedback from parents and teachers indicated that the program was effective at creating positive changes in the childrenʼs behavior. While short-term outcomes were evident, further investigation into the long-term sustainability of these changes are needed.

Title: First Photographic Evidence of Pallas’s Cat (Otocolobus manul) from Himachal Pradesh, India

Author: Sharma, C., Thuktan, T., Tobge, R., Angrup, D., Chhering, D., Sherab, T., Chhering, T., Bajaj, D., Khanyari, M., Suryawanshi, K.

Abstract: While the study of carnivore ecology has made significant progress, our knowledge of small cats remains limited. For some species, their distribution remains largely unknown. We report the first photographic evidence of the Pallas’s cat in Himachal Pradesh, India. Of the 56 camera traps placed for snow leopard population estimation across Kinnaur region between March-May 2024, we recorded Pallas’s cat at three camera trap sites with 19 images from three instances during morning hours. These captures were at an elevation of 3900–4100 meters in rocky habitats largely dominated by boulders and cliffs. Sympatric carnivores captured were snow leopard (Panthera uncia), red fox (Vulpes vulpes), stone marten (Martes foina) and free-ranging dogs. This discovery not only extends the known distribution of Pallas’s cat but also underscores the urgent need for focused conservation research and action in this region, especially given the presence of free-ranging dogs. This can be achieved through coordinated, landscape level and trans-boundary efforts.

Title: Return of the Eurasian lynx: using local stakeholder knowledge and experiences to inform lynx conservation in the French Alps

Author: Alexander, J. S., Christe, P., Zimmermann, F.

Abstract: Large carnivore conservation in human-dominated landscapes is a complex issue, often marked by the stark contrast between those who hold deep-rooted animosity towards these animals and those who welcome their presence. The survival of the Eurasian lynx Lynx lynx in Europe relies on effective coexistence with humans in multi-use areas. We explored the experiences and perceptions of local hunters and pastoralists regarding the return of the lynx to the Giffre Valley, France, and mapped lynx distribution based on the probability of site use while accounting for detection probability. We conducted in-depth interviews with 29 respondents to gather data on lynx sightings, rationale for hunting and pastoralism, and perceptions of lynxes. We found that 45% of respondents had detected lynxes in the last 40 years, with an estimated site use of 0.66 ± SE 0.33 over the last decade, indicating there was a 66% probability of lynxes using the sites during that time period. Our results suggest that hunting and pastoralism in the region are rooted in a desire to carry on local traditions and connect with the natural world. Respondents generally tolerated the presence of lynxes, perceiving few threats to their livelihoods and activities, and expressing a willingness to coexist peacefully. However, some identified future challenges that could arise with the return of large carnivores to the valley and highlighted scenarios that could lead to a decline in tolerance. This study emphasizes the valuable knowledge of local hunters and pastoralists and their potential role in lynx population monitoring and conservation. Integrating stakeholder values in decision- making processes is crucial for inclusive and sustainable responses to promote biodiversity.

Title: Monitoring of snow leopards in the Sarychat-Ertash State Reserve (Kyrgyzstan), between 2011 and 2019, through scat genotyping

Author: Rode, J., Cabanat, A., Pelletier, A., Kaerle, C., Pirog, A., Dufaure de Citres, C., Queney, G., Chaix, B., Vereshagin, A., Casane, D.

Abstract: Snow leopards (Panthera uncia) are a keystone species of Asia’s high mountain ecosystem. The species is assessed as Vulnerable by the IUCN Red List of Threatened Species and is elusive, limiting accurate population assessments that could inform conservation actions. Non-invasive genetic monitoring conducted by citizen scientists offers avenues to provide key data on this species. From 2011 to 2019, OSI-Panthera citizen science expeditions tracked signs of presence of snow leopards and collected scat samples along transects in the main valleys and crests of the Sarychat-Ertash State Reserve (Kyrgyzstan). Scat samples were genotyped at twenty autosomal microsatellite loci and at a X/Y locus (sex identification), allowing an estimation of a minimum of 17 individuals. The genetic recapture of 12 of them provided indications of individuals’ habitat use throughout the reserve. We found putative family relationships between several individuals; however, further research is needed to validate these findings. Our results demonstrate the potential of a citizen science program to collect meaningful data that can inform the conservation management of snow leopards.

Title: Collaborative conservation for snow leopards: Lessons learned from successful community-based interventions

Author: Young, J. C., Alexander, J. S., Agvaantseren, B., Bijoor, A., Butler, A., Nawaz, M. A., Piaopiao, T., Searle, K. R., Uulu, K. Z., Zhi, L., Suryawanshi, K. R., Redpath, S. M., Mishra, C.

Abstract: Collaborative conservation interventions based on engagement with local communities are increasingly common, especially for large carnivores that negatively impact people’s livelihoods and well-being. However, evaluating the effectiveness of large-scale community-based conservation interventions is rarely done, making it problematic to assess or justify their impact. In our study focused on snow leopards (Panthera uncia) in five countries, we show that bespoke and well- implemented community-based and conflict management intervention efforts can lead to more sustainable conservation outcomes. Collaborative interventions, spread over about 88,000 km2 of snow leopard habitat, reduced livestock depredation and disease and associated economic costs. Additionally, they generated conservation-linked livelihoods and enhanced community decision-making, leading to more positive behavioral intent toward snow leopards and improved communities’ cooperation, economic security, an
d confidence. Our results provide lessons learned and recommendations for practitioners and governments to alleviate conflicts and foster coexistence with snow leopards and large carnivores more broadly. These include prioritizing locally led tailored solutions based on the PARTNERS principles, recognizing local community rights in conservation decision-making, and recognizing the role of social norms in ensuring accountability.

Title: Geospatial assessment of climate and human pressure on Snow Leopard habitat in the Trans-Himalayan region of Pakistan

Author: Hani, U., Haq, S. M., Shabbir, R., Waheed, M., Jabeen, A., Hussain, M., Najar, Z. H., Alhimaidi, A. R., Amran, R. A., Bussmann, R. W.

Abstract: Reliable estimates of how human activities may affect wildlife populations are critical for making scientifically sound resource management decisions. A significant issue in estimating the consequences of management, development, or conservation measures is the need to account for a
variety of biotic and abiotic factors, such as land use and climate change, that interact over time altering wildlife habitats and populations. The snow leopard Panthera uncia (Schreber, 1775), as a vulnerable species, is extremely sensitive to indirect impacts of climate change. Given that it is
highly difficult undertaking conservation measures on the entire range of snow leopards, identifying hotspots for conservation is necessary. This study was conducted in Bagrot and Haramosh valleys, in the Trans-Himalayan region, to evaluate the impacts of climate and human pressure on snow leopard habitat. Hybrid classification of Landsat satellite data for 2010 and 2020 was performed to elucidate land use changes that suggested a decrease in permanent snow by 10 % and 3 % in Haramosh and Bagrot while an increase in settlements cover by 16 % and 23 %, respectively. Life zone comparison for 2010 and 2020 using the Holdridge life zone (HLZ) classification system disclosed a change from three life zones to five life zones in Haramosh, and four life zones to five life zones in Bagrot, caused by a temperature increase of 2◦C to 3◦C, indicating that the area is becoming more and more suitable for settlements and less favorable for snow leopards. This study underlines again that mountainous regions are more vulnerable to the impacts of climate change. Warming weather is making survival more difficult for snow leopards. Although they are resilient to the direct effects of climate change, indirect impacts like avalanches, flash floods, urbanization, and human-wildlife conflict make them more vulnerable and threaten their survival. Thus, we recommend establishing further protected areas, better controlling illegal wildlife trade, and conducting genetic studies to understand impacts on snow leopards and rangeland management, livelihood improvement, and human-wildlife conflict reductions.

A., Ostrowski, S., Paltsyn, M., Poyarkov, A., Rabinowitz, S., Rooney, T., Rosen, T., Rozhnov, V. V., Sacks, B. N., Schwartz, M. K., McCarthy, K. P.

Abstract: Snow leopards (Panthera uncia) inhabit the mountainous regions of High Asia, which experienced serial glacial contraction and expansion during climatic cycles of the Pleistocene. The corresponding impacts of glacial vicariance may have alternately promoted or constrained genetic differentiation to shape the distribution of genetic lineages and population structure. We studied snow leopard phylogeography across High Asia by examining range-wide historical and contemporary genetic structure with mitochondrial DNA and microsatellite markers. We genotyped 182 individuals from across snow leopard range and sequenced portions of the mitogenome in a spatially stratified subset of 80 individuals to infer historical biogeographic and contemporary patterns of genetic diversity. We observed a lack of phylogeographic structure, and analyses suggested a single refugial origin for all sampled populations. Molecular data provided tentative evidence of a hypothesized glacial refugia in
the Tian Shan-Pamir-Hindu Kush-Karakoram mountain ranges, and detected mixed signatures of population expansion. Concordant assessments of microsatellite data indicated two global genetic populations, though we detected geographic differences between historical and contemporary population structure and connectivity inferred from mitochondrial and microsatellite data, respectively. Using the largest sample size and geographic coverage to date, we demonstrate novel information on the phylogeographic history of snow leopards, and corroborate existing interpretations of snow leopard connectivity and genetic structure. We recommend that conservation efforts incorporate genetic data to define and protect meaningful conservation units and their underlying genetic diversity, and to maintain the snow leopard’s adaptive potential and continued resilience to environmental changes.

Title: Snow leopards and water: high waterhole visitation rate by a breeding female in summer

Author: Lkhagvajav, P., Alexander, J. S., Byambasuren, C., Johansson, O., Sharma, K., Mishra, C., Samelius, G.

Abstract: Water is a limiting resource in arid environments where space use of animals is often driven by access to water during the dry times of the year. Here we report on a breeding female snow leopard visiting a waterhole 37 times in June and July in 2015. These observations show that space use of snow leopards can be driven strongly by access to water during certain times of the year such as when lactating and the need for water is increased. Strong dependence on water during certain times of the year suggest that climate change and high human pressure on limited water sources may have negative impact on snow leopards and other wildlife in the mountains of High Asia.
