Human-wildlife conflict (HWC) is a pressing issue worldwide but varies by species over time and place. One of the most prevalent forms of HWC in the mid-hills of Nepal is human-common-leopard conflict (HLC). Leopard attacks, especially in forested areas, can severely impact villagers and their livestock. Information on HLC in the Gorkha district was scarce, thus making it an ideal location to identify high-risk zones and landscape variables associated with such events. Registered cases were collected and reviewed from the Division Forest Office (DFO) during 2019-2021. Claims from DFO records were confirmed with herders and villagers via eight focus group discussions. To enhance modeling success, researchers identified a total of 163 leopard attack locations on livestock, ensuring a minimum distance of at least 100 meters between locations. Using maximum entropy (MaxEnt) and considering 13 environmental variables, we mapped common leopard attack risk zones. True Skill Statistics (TSS) and area under receiver-operator curve (AUC) were used to evaluate and validate the Output. Furthermore, 10 replications, 1,000 maximum iterations, and 1000 background points were employed during modeling. The average AUC value for the model, which was 0.726 ± 0.021, revealed good accuracy. The model performed well, as indicated by a TSS value of 0.61 ± 0.03. Of the total research area (27.92 km2), about 74% was designated as a low-risk area, 19% as a medium-risk area, and 7% as a high-risk area. Of the 13 environmental variables, distance to water (25.2%) was the most significant predictor of risk, followed by distance to road (16.2%) and elevation (10.7%). According to response curves, the risk of common leopard is highest in the areas between 1.5 to 2 km distances from the water sources, followed by the closest distance from a road and an elevation of 700 to 800 m. Results suggest that managers and local governments should employ intervention strategies immediately to safeguard rural livelihoods in high-risk areas. Improvements include better design of livestock corrals, insurance, and total compensation of livestock losses. Settlements near roads and water sources should improve the design and construction of pens and cages to prevent livestock loss. More studies on the characteristics of victims are suggested to enhance understanding of common leopard attacks, in addition to landscape variables. Such information can be helpful in formulating the best management practices. [ABSTRACT FROM AUTHOR]

Himalayan Musk deer, Moschus chrysogaster is widely distributed but one of the least studied species in Nepal. In this study, we compiled a total of 429 current presence points of direct observation of the species, pellets droppings, and hoofmarks based on field‐based surveys during 2018–2021 and periodic data held by the Department of National Park and Wildlife Conservation. We developed the species distribution model using an ensemble modeling approach. We used a combination of bioclimatic, anthropogenic, topographic, and vegetation‐related variables to predict the current suitable habitat for Himalayan Musk deer in Nepal. A total of 16 predictor variables were used for habitat suitability modeling after the multicollinearity test. The study shows that the 6973.76 km2 (5%) area of Nepal is highly suitable and 8387.11 km2 (6%) is moderately suitable for HMD. The distribution of HMD shows mainly by precipitation seasonality, precipitation of the warmest quarter, temperature ranges, distance to water bodies, anthropogenic variables, and land use and land cover change (LULC). The probability of occurrence is less in habitats with low forest cover. The response curves indicate that the probability of occurrence of HMD decreases with an increase in precipitation seasonality and remains constant with an increase in precipitation of the warmest quarter. Thus, the fortune of the species distribution will be limited by anthropogenic factors like poaching, hunting, habitat fragmentation and habitat degradation, and long‐term forces of climate change.

Nepal initiated numerous hydropower and irrigation‐related infrastructure projects to enhance and promote green energy, water security, and agricultural productivity. However, these projects may pose risks to natural habitats and the well‐being of aquatic fauna, leading to significant effects on delicate ecosystems. To understand these potential impacts, it is crucial to gather reliable baseline data on the population status and habitat characteristics of species. This study specifically focuses on Gharials (Gavialis gangeticus), a critically endangered species. We recorded data on pre‐determined habitat variables at stations spaced 500 m apart along the two major river streams of Bardia National Park, as well as at locations where Gharials were sighted between February and March 2023. We used binary logistic regression with a logit link function to investigate the habitat characteristics related to the occurrence of Gharials. The presence/absence of Gharials at sampling points served as the dependent variable, while 10 other predetermined variables (ecological variables and disturbance variables) served as independent variables. Our study recorded 23 Gharials, comprising 14 adults, six sub‐adults, and three juveniles, with a sex ratio of 55.56 males per 100 females. Most individuals (83%) were found basking. Among the 10 habitat predictors, three variables (mid‐river depth, river width, and water temperature) were significantly correlated (p <.05) with the probability of Gharial occurrence. The model shows that Gharial detection probability increases with greater mid‐river depth and width and lower water temperature. This study establishes a population baseline for Gharials within the river system before the construction of large infrastructure projects, such as dams and irrigation canals. It also recommends continuous monitoring of Gharial populations after water release and/or diversion to evaluate the impact of large infrastructure projects on the population and their associated habitat characteristics. This will help enable more informed and targeted conservation efforts. [ABSTRACT FROM AUTHOR]

Information on the spatial and temporal patterns of losses caused by leopard (Panthera pardus) in terms of human attacks and livestock depredation in the human-dominated landscape of the mid-hills of Nepal is essential in formulating and implementing effective mitigation measures. This study aimed to assess the spatial and temporal patterns of leopard attacks on humans and livestock and the economic losses incurred by livestock depredation between 2015 and 2019 in the Bhanu municipality of Tanahun District. We adopted a household survey (N = 110), key informant (N = 10), and focus group discussion (N = 4) for this study. We purposively chose two conflict wards: 2 and 4, based on the severity of the attacks by the leopard. Within each ward, we selected the households randomly and conducted a semistructured questionnaire survey in September 2020. A total of 8 incidents of human attacks and 142 incidents of livestock depredation were recorded, with six human casualties in ward 2 and 1.45 incidents of livestock depredation per household in ward 4. The maximum attack was observed during 2019 both on humans (n = 6) and livestock (n = 67). Leopards mostly attacked children below 9 years, living within 200 m of the nearest forest edge, with the highest attack during the autumn months (62.5%). During the five years, leopard killed goats that represent 83.1% of total livestock loss categories. A significant difference was found in the frequency of attacks on livestock over the years (χ2 = 87.60, df = 4, and P ≤ 0.01), months (χ2 = 16.53, df = 11, and P = 0.12), and time of day (χ2 = 48.47, df = 3, and P ≤ 0.001) with the highest attack during the year 2019 (47.18%), July (14.08%), and daytime (42.96%), respectively. Households living nearer to the forest edge (<200 m) lost more livestock (72.54%). The monetary value of a total of 8142 USD (74 USD per household) was lost due to livestock depredation, with major monetary loss at a distance >400 m from the forest edge. We suggest adopting mitigation measures like predator-proof livestock corals while stall feeding and strengthening conscientious livestock herding practices during grazing, encouraging livestock insurance schemes, educating local communities about leopard behavior, caring for and protecting children intensively in the leopard attack sites, improving the prey base in the wild, and timely management of man-eater leopard to reduce the conflict in the study area and the country.

Simple Summary: Rapidly changing environmental conditions can alter the spatial distribution of flora and fauna. This study aimed to understand the influence of environmental variables on the Blue bull's distribution and identify potential conflict zones in Nepal. Using ensemble modeling, the habitat suitability analysis of the Blue bull was performed by selecting 15 ecologically significant environmental variables and employing ten species distribution modeling algorithms. Random Forest, Maxent, and Generalized linear models showed the highest mean true skill statistics scores and were further analyzed. The study found that 15.26% of Nepal, or 22,462.57 km2, is suitable for the Blue bull, and the environmental variables contributing to the distribution of the Blue bull were slope, precipitation seasonality, and distance to the road. Furthermore, 45% of the predicted suitable habitats overlap with agricultural land, highlighting the potential for human–Blue bull conflicts. Therefore, this study recommends implementing appropriate conflict mitigation measures, such as cooperatively guarding crops, changing cropping patterns, using repellents, fencing, translocation, physical barriers, and sterilization. This study establishes a baseline for suitable habitats for the Blue bull and identifies potential conflict zones in Nepal, emphasizing the need for conservation initiatives inside and outside protected areas. Rapidly changing environmental conditions (bioclimatic, anthropogenic, topographic, and vegetation-related variables) are likely to alter the spatial distribution of flora and fauna. To understand the influence of environmental variables on the Blue bull's distribution and to identify potential conflict zones, the habitat suitability analysis of the Blue bull was performed using ensemble modeling. We modelled the distribution of the Blue bull using an extensive database on the current distribution of the Blue bull and selected 15 ecologically significant environmental variables. We used ten species distribution modeling algorithms available in the BIOMOD2 R package. Among the ten algorithms, the Random Forest, Maxent, and Generalized linear model had the highest mean true skill statistics scores, ensuring better model performance, and were considered for further analysis. We found that 22,462.57 km2 (15.26%) of Nepal is suitable for the Blue bull. Slope, precipitation seasonality, and distance to the road are the environmental variables contributing the most to the distribution of Blue bull. Of the total predicted suitable habitats, 86% lies outside protected areas and 55% overlaps with agricultural land. Thus, we recommend that the future conservation initiatives including appropriate conflict mitigation measures should be prioritized equally in both protected areas and outside protected areas to ensure the species' survival in the region.

Pangolins are among the most extensively traded taxa in southeastern Asia mainly due to the perceived medicinal value of their scales and other body parts, putting them at risk of extinction, however, little is known about their trade status in Nepal. The purpose of the study was to assess the status of pangolin trade in Makwanpur district of Nepal. Semi-structured interview with household (n = 90), key informant survey (n = 15), Four focus group discussion at each study site was conducted. Seizure data (2015-2019) were gathered from the law enforcement agencies to identify and analyze the major trade routes. The majority of the respondents (63%) were well aware of the protection status of pangolins. Further, our study found that historically local peoples used pangolin body parts in making rings, bags, jackets, and musical instruments but at present they stopped it. Pangolin traders were typically middle-aged men and unemployed youth. Majority of the hunting was found to be opportunistic but when pangolins were caught, they were generally sold for additional income. Currently, the seizure data has shown the declining trend of pangolin trade within the Makwanpur district. Community forest user groups and community based anti-poaching units are working actively for the conservation and promulgation of threatened pangolins in the Makwanpur district which had long served as a major trade route to China. Thus, we advocate strengthening border security and the formation of community-based anti-poaching units, followed by mobilization, anti-poaching trainings, security assurance, and incentives for worthy conservation results in pangolin-rich communities. Further, we recommend sustained conservation awareness programs, in addition to alternative livelihood opportunities, for the long-term conservation of pangolins and their habitat.

The Chinese pangolin is a critically endangered and biologically unique species, yet information on its status, distribution, and habitat preferences is still scarce in Nepal, which limits effective conservation action. This study identified the current burrow density status, distribution pattern, and important habitat parameters associated with Chinese pangolin distribution in Nepal through opportunistic field surveys. Fifty‐four belt transects were examined for the presence of pangolin burrows. For each active burrow (burrow with freshly dug soil, footprints, and scat near the entrance) and old burrow (burrow with compacted soil, presence of dead leaves, and spider web in the entrance), we recorded the geographic coordinates and assessed data on 11 habitat parameters that included elevation, aspect, slope, canopy cover, ground cover, presence or absence of ant and termite colonies, habitat type, soil type, and distances to the nearest water source, road, and settlement. A total of 141 active burrows and 430 old burrows were recorded with an overall clumped distribution S2/a=2.188$$ \left\{\left({S}^2/a\right)=2.188\right\} $$. Active burrow density was estimated to be 1.04 burrows/ha. Of the 11 habitat parameters predicted to influence the probability of encountering pangolin burrows, all parameters were significant except elevation. More than 92% of the burrows were found at elevations between 450 and 750 m and facing either the SE or NW aspect. Similarly, about 90% of the burrows were distributed in areas having slopes between 0% and 30% with moderate to high canopy and ground cover, and located close to water sources, roads, and settlements. Additionally, they strongly preferred forest habitats (with Shorea robusta, Castanopsis indica, Schima wallichii, Clerodendron infortunatum, and Nephrolepis auriculata as the dominant vegetation), areas with red soil, and areas located near ant and termite colonies. Although the study area currently provides suitable habitat for Chinese pangolins, it is slowly being degraded due to increasing rates of forest degradation. Conservation efforts should be increased in order to protect this critically endangered species and their preferred habitats. Finally, our findings reveal the preferred habitat characteristics of Chinese pangolins, which could be instrumental for policy makers and forest managers in making conservation plans for Chinese pangolins.

Non-timber forest products (NTFPs) contribute to livelihood of rural communities which is influenced by numerous socio-economic variables. This study assessed the financial contribution of Zanthoxylum armatum and the influence of respondents' various socio-economic characteristics on such contribution in Ghatan of Beni Municipality, Myagdi District, Nepal. For this study, we used semi-structured questionnaires to 80 purposively selected households, followed by 10 key informant interviews, four focus group discussions, and direct field observations. A Pearson correlation matrix was used to determine the dependence of several socio-economic variables on average annual household income from the sale of Z. armatum. The average annual income per household from the sale of Z. armatum was found to be the highest (494 USD) in Brahmin/Chhetri households and the lowest (372 USD) in Dalit households. Among five variables used in the regression model, only three of them: land holding size (khet), time taken to harvest (days), and wealth ranking (rich) were found positively significant with p-values of 0.042, 0.000, and 0.064 respectively. Whereas, the education status of the respondents (literate) and the main income source (agriculture) were found negatively significant with p-values of 0.046 and 0.064, respectively. Furthermore, we believe that this result will help to promote the conservation of Z. armatum and other valuable medicinal plants as well as their sustainable management in the study area and similar areas.

Simple Summary: The conservation of biodiversity depends on the viability of management regimes. In most cases, it is well established that government-managed lands aid in the conservation of biodiversity; however, little is known regarding the conservation effectiveness of community-managed areas (e.g., community forests) in relation to government-managed areas. In the mid-hill region of Nepal, we evaluate the effectiveness of community-managed and protected forests in supporting avian diversity. We discovered greater bird diversity, richness, and abundance in the community-managed forest compared to the protected forest. In addition, the turnover of bird species was greater in the community-managed forest compared to the protected forest. Our study demonstrates that community-managed forests can have a greater diversity and abundance of bird species than government-managed protected forest. Forest management practice plays a critical role in conserving biodiversity. However, there are few studies on how forest management practice affects bird communities. Here, we compare the effectiveness of the Panchase Protection Forest (PPF; protected forest with government administration) and the Tibrekot Community Forest (TCF; community forest with community forest users' group administration) in hosting bird diversity in the mid-hills of Nepal. We examined 96 point count stations during summer and winter in 2019 and recorded 160 species of birds with three globally threatened vultures (red-headed vulture Sarcogyps calvus, slender-billed vulture Gyps tenuirostris, and white-rumped vulture Gyps bengalensis). Forest management practice, season, and elevation all influenced the richness and abundance of birds. The diversity, richness, and abundance of birds and the most common feeding guilds (insectivore, omnivore, and carnivore) were higher in TCF than in PPF; however, globally threatened species were only recorded in PPF. We also recorded a higher bird species turnover (beta diversity) in TCF than in PPF. Our study indicates that community-managed forests can also provide quality habitats similar to those of protected forests managed by the government, and provide refuge to various bird species and guilds. However, we recommend more comparative studies in other tropical and sub-tropical areas to understand how different forest management practices influence bird diversity. [ABSTRACT FROM AUTHOR]

Background: Knowledge about the niche overlap among wild species and domestic cattle is helpful to conserve and manage wildlife. We assessed the habitat niche breadth and overlap of sympatrically living spotted deer (Axis axis) and domestic cattle with swamp deer (Cervus duvaucelii) in Shuklaphanta National Park, Nepal during the dry season to explore the possibility of interspecific competition by studying the habitat use by these species. The assumption was made that the presence of pellets is proof of habitat used by species. Methods: Grids of 2 km × 2 km have four subgrids, each with four sample plots, making a total of 16 plots (20 m × 20 m) in each grid. The size of each sub-grid was 200 m × 200 m and they were placed randomly inside the grid but at least 1 km apart from one another. The data was collected in a 96 plots in total. Levin's niche breadth and Morisita's overlap index were calculated to determine the niche breadth and the habitat overlap, respectively. Results: The Levin's measure of niche breadth suggested that spotted deer had the highest acclimatization with an index value of 0.94, followed by domestic cattle at 0.50, and swamp deer at 0.33 in our study area. Thus, our findings supported the evidence that spotted deer are habitat generalists, whereas swamp deer are habitat specialists. The swamp deer had lower niche breadth and more overlap with domestic cattle. Conclusion: Our study showed the least niche breadth of swamp deer in comparison to spotted deer and domestic cattle. The domestic cattle had the highest and least niche overlap with spotted deer and swamp deer, respectively, in terms of habitat use. Our study suggests that domestic cattle grazing should be stopped, and grassland management should be carried out for the benefit of ungulates. Similar studies should be conducted, including different seasons and places, prior to appropriate habitat management. In addition, further studies are needed to quantify the extent of interspecific competition by incorporating more species. [ABSTRACT FROM AUTHOR]

Wild Water Buffalo (WWB) Bubalus arnee is an endangered species and a protected animal in Nepal. The remaining WWB population is located in Koshi Tappu Wildlife Reserve (KTWR), and it appears to have low viability under prevailing conditions. We assessed the habitat use and conservation threats to wild water buffalo in KTWR. For habitat analysis the quadrant method was used. Eighty-four quadrants of 25 m2 for trees, 168 quadrants of 10m2 for shrubs and 336 quadrants of 1 m2 for herbs were laid out in the study area. Ivlev's electivity index (IV) was calculated to assess the use of different habitat components. The important Value Index (IVI) was used for vegetation assessment. A relative threat ranking method was used to assess conservation threats for wild buffalo and their habitats. Wild buffalo mostly preferred habitats with distance to water resources less than 500 m (IV= 0.4), less than 25 % crown coverage (IV= 0.39) and more than 75 % ground coverage (IV= 0.42). The trees species Phyllanthus emblica, Acacia catechu, shrub species Mimosa pudica and the herb species Brachiaria distachya, Vetiveria zizanioides, Imperata cylindrica, and Saccharum spontaneum were preferred by WWB in the study area. Among the different plant categories, we found that Acacia catechu was the most preferred tree species (IVI= 156.95), Mimosa pudica the most preferred shrub species (IVI= 58.68), and Imperata cylindrica the most preferred herb species (IVI= 64.73). Major conservation threats perceived by local stakeholders for wild buffaloes were overgrazing by cattle and genetic swamping through crossbreeding with domestic buffalo. Therefore, conservation of grass species through control of grazing, and prevention of cross breeding are measures supported by this study. Additionally, site-specific conservation strategies should be adopted, based on identified threats in the study area. [ABSTRACT FROM AUTHOR]

Himalayan or White-bellied Musk Deer Moschus leucogaster, an IUCN indexed endangered species, is distributed in isolated pockets in the Himalaya. The deer population is decreasing owing to several pressures that include habitat loss and fragmentation, and poaching. It is essential to identify preferred habitat characteristics to support appropriate management strategies for conserving this endangered species. This study was carried out in the Nysheang basin of Annapurna Conservation Area of Nepal to identify habitats preferred by the musk deer. Habitat field parameters were collected using transect surveys. To analyze vegetation use and availability, nested quadrate plots size 20 m2 were established. Ivlev’s electivity index (IV) (-1 to +1) was employed to determine habitat preference, and one-way ANOVA (F) and chi-square tests (χ2) were used to examine different habitat parameters. Similarly, the importance value index (IVI) of the vegetation was calculated. Our results showed that the Himalayan Musk Deer strongly preferred habitats at 3601–3800 m altitude (IV= 0.3, F= 4.58, P <0.05), with 21–30º slope (IV= 0.2, F= 4.14, P <0.05), 26–50 % crown cover (IV= 0.25, F= 4.45, P <0.05), 26–50 % ground cover (IV= 0.15, F= 4.13, P <0.05), and mixed forest (IV= 0.29, χ2= 28.82, df= 3, p <0.001). Among the trees, Abies spectabilis (IVI= 74.87, IV= 0.035) and Rhododendron arboretum (IVI= 55.41, IV= 0.02) were the most preferred, while Rhododendron lepidotum, Cassiope fastigiata (IV= 0.35) and Berberis aristata (IV= 0.25) were the most preferred shrubs, and Primula denticulata (IV= 0.87) and Primula rotundifolia (IV= 0.31) were the most preferred herbs. These preferred habitat conditions should be maintained and conserved to sustain a viable population of deer in the study area. Further studies will be required to assess the effects of climate change on habitat suitability. [ABSTRACT FROM AUTHOR]

Sloth bears (Melursus ursinus) are listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List of threatened species with a global population estimate of <17,000 individuals. In southwestern Nepal, Shuklaphanta National Park includes the largest uninterrupted expanse of grassland in the region and provides suitable habitat for sloth bears. No records of sloth bears from Shuklaphanta National Park, however, have been reported since 2013. We present the first photographic evidence of a sloth bear in Shuklaphanta National Park in a decade. In addition, we observed a Bengal tiger (Panthera tigris tigris) at the same location as the sloth bear 5 days later. These observations highlight the need for further research into the occurrence and movements of sloth bears in this region as well as the extent of co-occupancy and types of interactions between sloth bears and tigers.

The endangered hispid hare ( Caprolagus hispidus ) is one of the least studied mammal species. The recent rediscovery of hispid hare in Chitwan National Park (CNP) after three decades, necessitated urgent conservation measures. A detailed investigation into the species' ecology is imperative for developing evidence-based conservation strategies to support these efforts. The main objective of this study is to investigate the current distribution pattern and habitat preferences, offering vital insights for the effective preservation and management of the species and its habitat. Between 28 January and 13 February 2023, fifty-two surveys using strip transects were carried out in the potential areas. If any indirect signs of the presence of the hispid hare were identified, the corresponding value is coded as 1 "used plot". In contrast, a value of 0 was assigned if there is an absence of any indirect signs "habitat availability plot". Nine habitat predictors (habitat type, ground cover, distance to water source, distance to roads/path/firelines, ground condition, dominant plant species, presence/absence of (anthropogenic disturbance, predators, and invasive species), were measured from both plot types ("used plot" and "habitat availability plot"). Our research indicates a clumped distribution pattern within the CNP, with the Sukhibhar grassland identified as a key hotspot. Our study reveals the hispid hare's adaptability to diverse grassland conditions, favoring both tall and short grasslands. It is essential to integrate the species' preference for various grassland habitats and critical water sources to enhance conservation strategies. This requires a comprehensive grassland management plan for Chitwan National Park that preserves habitat diversity, safeguards key water sources, and adapts to evolving environmental conditions., Competing Interests: The authors declare there are no competing interests., (©2024 Prasai et al.)

Background: Gaur ( Bos gaurus ) is listed as a vulnerable species in the IUCN Red List of threatened species due to the rapid population decline caused by human pressures in their habitats. To develop successful conservation plans, it is essential to understand the relationship between Gaur and their habitats. This study aimed to investigate the factors influencing Gaur habitat use and identify and rank conservation threats in Chitwan National Park, Nepal., Methods: Using line transect surveys, we recorded Gaur's presence via direct sightings and indirect signs (dung, footprints, horns) over an area of 176 km 2 in July and August 2022. We used binary logistic regression models to determine the collected ecological and anthropogenic factors influencing the occurrence of Gaur and the relative whole-site threat ranking method to rank conservation threats., Results: The results revealed that the probability of Gaur occurrence increases with moderate to high canopy cover, riverine and Shorea robusta dominated forests, and nearest distance to road/path/firelines, while decreasing with the presence of predators. Uncontrolled fire, invasive species, human disturbances, and climate change were ranked as the most prevailing threats to Gaur in our study area. Conservation managers should implement effective habitat management interventions, such as construction of waterhole, firelines maintenance, grassland management, and control of invasive species in the potential habitats, to safeguard and maintain the sustainability of Gaur populations and associated herbivores. Future studies should consider larger geographical settings and multiple seasons, and habitat suitability assessments should be conducted to determine current and future suitable habitat refugia for Gaur and other threatened wildlife species at the landscape level., Competing Interests: The authors declare there are no competing interests., (©2024 Poudel et al.)
