1. Camera trapping is a widely employed tool in wildlife research, used to estimate animal abundances, understand animal movement, assess species richness and understand animal behaviour. In addition to images of wild animals, research cameras often record human images, inadvertently capturing behaviours ranging from innocuous actions to potentially serious crimes. 2. With the increasing use of camera traps, there is an urgent need to reflect on how researchers should deal with human images caught on cameras. On the one hand, it is important to respect the privacy of individuals caught on cameras, while, on the other hand, there is a larger public duty to report illegal activity. This creates ethical dilemmas for researchers. 3. Here, based on our camera-trap research on snow leopards Panthera uncia, we outline a general code of conduct to help improve the practice of camera trap based research and help researchers better navigate the ethical-legal tightrope of this important research tool.

Camera trapping is especially valuable when research or management involves elusive species living in difficult to access habitats (O'Connell et al., 2011). Camera traps are used to estimate animal abundances, understand animal movement (Borchers, Distiller, Foster, Harmsen, & Milazzo, 2014), assess species This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Studies on common pool resource governance have largely focused on men, who tend to have disproportionate rights and ownership with regards property and resources. This has resulted in the access and control rights of women being generally overlooked. Gender disaggregated analyses have revealed the important role of women in the governance of the commons. While certain commons may be relatively more important for women, there are variations in their level of resource access and management role, influenced by social structures and divisions. We examined the role of gender and how such intersectionality could shape the governance of the commons in the Spiti Valley in the Indian Trans-Himalaya. We found that gender, class, and caste intersected in the governance of irrigation water. Our study highlights the role of women in the governance of the commons and points to the nuanced and variable roles found within this gender group.

1. Effective management of charismatic large carnivores requires robust monitoring of their population at local, regional and global scales. While enormous progress has been made to estimate carnivore populations at local scales, estimates at regional and global scales remain elusive. In the first systematic effort at a large regional scale, we estimated the population of the elusive snow leopard Panthera uncia over an area of 26,112 km 2 in the Indian state of Himachal Pradesh.2. We stratified the entire snow leopard habitat in Himachal Pradesh based on an occupancy survey. Subsequently, we conducted camera trapping surveys at 10 sites distributed proportionately, that is with similar coverage probability across the three strata. We conducted simulations to understand how unidentified captures could affect our model estimate. We also assessed populations of the primary wild ungulate prey of snow leopards -blue sheep Pseudois nayaur and Siberian ibex Capra sibirica.3. Our results yielded a mean estimated density of 0.19 (95% confidence interval [CI]: 0.12-0.31) snow leopards per 100 km 2 and population size of 51 (95% CI: 34-73) snow leopards in Himachal Pradesh. The density estimates for individual sites ranged from 0.08 to 0.37 snow leopards per 100 km 2 . Simulations showed that unidentified snow leopard captures did not seem to affect the accuracy of our model estimate but could have affected the precision. Wild ungulate prey density ranged from 0.11 to 1.09 per km 2 . Snow leopard density showed a positive linear relationship with prey density (slope = 0.25, SE = 0.08, P = 0.01, R 2 = 0.51).4. Our study shows the earlier opinion-based estimate for Himachal Pradesh to have been significantly positively biased. Using occupancy surveys to stratify large areas in order to design camera trap surveys addresses one of the common spatial sampling biases, that is limited sampling of only prime snow leopardThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Summary Protection of biodiversity requires inclusive and gender-responsive programming. Evidence of success in engaging women in large carnivore conservation remains scarce, however, although women play an important role in caring for livestock at risk of predation and could contribute to large-carnivore conservation. We aimed to assess the performance of an income-generation and skills-building programme for women in Spiti Valley (India) that sought to engage women in local conservation action. Annual programme monitoring together with a one-time survey of attitudes, perceptions and social norms in eight communities exposed to the conservation programme and seven ‘control’ communities revealed: a keen interest and increasing levels of women’s participation over 7 years of programme operation; participant reports of multiple programme benefits including additional personal income, social networking and travel opportunities; and more positive attitudes towards snow leopards among programme participants than among non-participants in the control communities. Women from programme communities recorded in their diaries 33 self-directed conservation actions including improving livestock protection and preventing wildlife poaching. These results show a way forward to purposively engage women in conservation programming towards achieving sustainable and equitable outcomes in efforts to promote carnivore–human coexistence.

Mitigating livestock predation by carnivores is crucial to ensure carnivore conservation and facilitate human-carnivore coexistence. Mitigation measures proposed by conservation agencies, however, are often technocratic and perceived as being an external imposition on the local community. Herders affected by the depredation may have the knowledge to design locally relevant solutions, but they might lack financial and technical support to implement these effectively. Their inability to act can result in the communities being viewed as antagonistic rather than a part of the solution. We present a case study on co-development of a conservation intervention by a traditional pastoral community together with a conservation NGO, to mitigate livestock depredation inside night-time corrals in Ladakh, India. Between January and June 2020, livestock corrals in Sumdoo TR village were attacked 10 times by carnivores such as snow leopards and wolves, killing over 100 sheep, goat, yak, and horses and causing loses of over 10,400 USD. Local people were agitated, and there were strong demands for capture or removal of the carnivores from the area. We operationalized the PARTNERS (Presence, Aptness, Respect, Transparency, Negotiation, Empathy, Responsiveness, and Strategic Support) principles framework for community-based conservation to help the village effectively implement an intervention based on a novel predator-proof corral design conceptualized by the community. We demonstrate that empowering the community to design and implement a conservation intervention helped them take ownership of the effort, improve trust with conservation agencies, and hence likely to be a long-term solution to conservation conflicts in the region. Our approach of using the PARTNERS principles has relevance for conservation agencies who are trying to implement interventions, particularly those geared toward reducing livestock depredation by carnivores. Our approach further helps communities to view themselves as part of the solution and not the problem.
