Show moreIn this study we determined the probability of predator attacks on livestock around Bardia National Park, Nepal. We conducted semi-structured interviews to explore the patterns and factors affecting livestock losses in four administrative sectors of the Park's buffer zone. We developed models to investigate the overall probability of livestock loss, economic damage caused, and the respondents’ attitudes towards wildlife. The probability of leopard attacks on livestock was much higher (85% of all livestock lost to depredation) than that of tiger attacks (8%), and the northern sector experienced the highest loss of livestock (50% modelled probability of livestock loss) in the buffer zone. Livestock loss was significantly related to the number of livestock owned by respondents, their ethnic group, and village distance to the Park boundary. Economic damage was influenced by buffer zone sector, number of livestock owned, and distance to the Park boundary. Conservation attitudes depended on respondents’ knowledge of wildlife, levels of education and self-sufficiency, and the probability of livestock being killed by leopards. Respondents who were male, highly educated and self-sufficient were most likely to support conservation. Tigers are tolerated based on religious beliefs, and these cultural values, together with the sharing of conservation benefits, facilitate conservation. Leopards, however, are not tolerated in the same way and are the most damaging predators. Show less

Show moreLeopards are known to prey on livestock throughout their range. Depredation of livestock makes leopards vulnerable to retaliatory killings and reduces public support for conservation. We examined spatiotemporal patterns, correlates, as well as economic losses and compensation paid for livestock depredation by leopards in buffer zone of Chitwan National Park, Nepal during 2007–2016. Records of compensation applications filed by livestock owners with the park and buffer zone authorities were collected and then triangulated through a questionnaire survey (n = 123). Of the 424 livestock that were reportedly killed by leopards, goats were disproportionately represented (87.3%), 20% more than expected from their relative livestock population, followed by pigs (8.7%) and cattle (4%). A conflict map prepared depicted "depredation hotspots" and clustering of incidents in certain parts of the area. There was a general decrease in livestock killings during the ten-year period. The killings varied significantly among years and months, but not among seasons. None of the examined factors namely, human population (abundance), livestock population (abundance), forest area in buffer zone, national park boundary (defined as the length of buffer zone user committee border abutting the park), livestock depredation by tigers, rainfall, and temperature were correlated with livestock depredation. Depredation by leopards resulted in a total economic loss of US$ 24,621 ($2462 per year) and compensation amounted to a total payment of US$ 19,719 ($1972 per year). We suggest improved husbandry practices, promotion of livestock insurance scheme, and conservation education for vulnerable communities in buffer zone. Show less

Show moreWe investigated the factors facilitating co-occurrence of two large carnivores, tigers (Panthera tigris) and common leopards (Panthera pardus), within a human-dominated landscape. We estimated their density and population size using camera-trap photographs and examined spatial segregation of habitats, temporal activity pattern, and diets in Chitwan National Park, Nepal. A Bayesian spatially-explicit capture-recapture model estimated densities of 3.2–4.6 (3.94 ± 0.37) tigers and 2.6–4.1 (3.31 ± 0.4) leopards per 100 km2 with abundance of 70–102 tigers and 66–105 leopards. Tigers occupied the prime habitats (grasslands and riverine forests) in alluvial floodplains of the Park whereas leopards appeared in Sal forests and marginal areas where livestock are present. Both tigers and leopards showed crepuscular activity patterns with a high overlap but tigers were less active during the day compared to leopards. Leopards’ activity in the day increased in the presence of tigers. Tiger and leopard diet overlapped considerably (90%). Compared to leopards, tigers consumed a higher proportion of the large prey and a smaller proportion of livestock. Our study demonstrates that sympatric large carnivores can coexist in high densities in prey-rich areas that contain a mosaics of habitats. To increase the resilience and size of the Chitwan carnivore population, strategies are needed to increase prey biomass and prevent livestock depredation in adjacent forests. Long-term monitoring is also required to obtain a detailed understanding of the interaction between the large carnivores and their effects on local communities living in forest fringes within the landscape.

Show moreInformation on density and abundance of globally threatened species such as tigers Panthera tigris is essential for effective conservation as well as to evaluate the success of conservation programmes. We monitored tigers in Parsa Widlife Reserve, Nepal, using camera traps, in 2013, 2014 and 2016. Once believed to be a sink for tigers from adjacent Chitwan National Park, Parsa now provides a new hope for tigers. Spatially explicit capture–recapture analysis over 3 survey years revealed an increase in tiger density from 0.78 to 1.38 individuals per 100 km2 from 2013 to 2016. The tiger abundance was estimated to be seven (6–13), 11 (10–16) and 17 (17–20) in 2013, 2014 and 2016, respectively. Resettlement of communities from the core area, reduced anthropogenic pressure, and improved security have made Parsa Wildlife Reserve a suitable habitat for tigers. Tiger abundance increased considerably within a 5 km radius of the evacuated village sites, from two in 2013 to eight in 2014 and 10 in 2016. Population turnover has remained moderate (< 30% per year), with persistence of individuals in multiple years. Dispersing tigers from Chitwan's source population accounted for a large portion (c. 40%) of the tigers detected in Parsa. Conservation efforts along with annual monitoring should be continued in Parsa to sustain the increase and monitor the persistence of tigers. The Chitwan–Parsa complex should be managed as a single ecological unit for conserving the Endangered tiger and other wide-ranging species. Show less

Show moreWe analyzed characteristics of the problem-causing tigers in Chitwan National Park (Nepal) to determine if specific groups or individuals in the source population have higher probability to get involved in conflicts with humans. From 2007 to 2016 we identified a total of 22 such tigers including 13 that killed humans, six serial livestock killers and three tigers that threatened human safety (with no reported human and livestock casualty). Thirteen of these tigers were controlled or killed and four were relocated. We compared a subset of 15 ‘problem tigers’ involved in conflict between 2009 and 2013 with the Chitwan's tiger population obtained from three different sessions of camera trapping (2009, 2010 and 2013). We found that <5% of this source population (tigers recorded in camera trap) were involved in conflict. We conclude that transient tigers without a territory or physically impaired animals are more likely to be involved in conflict and recommend an early warning system be adopted to anticipate conflicts before they occur. This system should include regular monitoring and timely identification of problem tigers followed by decisive management action to either remove the tiger or encourage local people to modify their behavior to reduce the risk of conflict.

Show moreRusty-spotted cat Prionailurus rubiginosus is the smallest wild cat, believed to be distributed only in India and Sri Lanka. Recently it was discovered from wider areas than previously thought but never recorded from Nepal. During a camera trap survey primarily targeted for tigers Panthera tigris, rusty-spotted cat was photographed multiple times on a single camera trap station in Shuklaphanta Wildlife Reserve in January and February 2016. The camera trap location is in dry-deciduous Sal Shoresa robusta forest in core area of the reserve at a distance of approximately 5 km from settlements. This is the first photographic evidence of rusty-spotted cat captured in camera traps in Nepal. Similarly, a photograph of a cat species taken by a park visitor in 2012 from Bardiya National Park was confirmed as rusty-spotted cat. With this record, Nepal has 12 felid species: tiger, common leopard Panthera pardus, snow leopard Panthera uncia, clouded leopard Neofelis nebulosa, Eurasian Lynx Lynx lynx, Asiatic golden cat Catopuma temminckii, fishing cat Prionailurus viverrinus, jungle cat Felis chaus, leopard cat Prionailurus bengalensis, marbled cat Pardofelis marmorata, Pallas's cat Otocolobus manul and rusty-spotted cat.
