Abstract
Human-wildlife conflict (HWC) is on an increasing trend and has become one of the most challenging problems for the rural communities of developing nations like Nepal. There is limited information available on HWC in Kailali district, Nepal. The objective of our study was to explore the different incidents and the perceptions of local people on HWC within four different sites in Kailali district. To collect information three different methods were used, a questionnaire survey (n= 80), key informant interviews (n= 10) and focus group discussions (n= 4); all during February and March 2018. Different records of HWC incidents were collected that occurred during the period of one year in 2017, except for information on human attacks which were collected from 2015 to 2017. Of the total of 102 HWC incidents, crop damage was the most severe problem followed by property damage (15) and livestock depredation (9). The Asian elephant (n= 54) was the most conflicting species for crop damage, followed by the Rhesus macaque (n= 23) and the wild pig (n= 14). Similarly, property damage was mostly caused by elephants (n= 10) and other animals (n= 5). Rice (43%) was the most damaged crop type by the conflicting species, followed by wheat (28%) and then maize (9%). For property damage, 19% of respondents reported suffering house damage while 11% suffered damage to stored food. Shouting and hitting drums was the most applied measure during HWC’s but other measures for human-wild animals co-existence and resolution are suggested.

Abstract
The Gharial (Gavialis gangeticus), also known as the gavial or fish-eating crocodile, is a member of the family Gavialidae, is the most threatened of the two species of crocodilians found in Nepal. However, sufficient information on its habitat characteristics influencing population status, distribution, and threats to its existence are lacking. We studied the gharial population in the Narayani River that was carried out in the winter season during December 2019 to April of 2020. During our surveys, a total of 117 gharials were recorded, including an adult male, 56 adult females, 19 sub-adults, 32 immature and nine were unidentified. The gharial census recorded 57 gharials in Sikrauli-Amaltari (Chitwan branch) river section followed by 14 in Sikrauli-Amaltari (Nawalparasi branch), 16 in Amaltari-Baguwan and 30 in the Baguwan-Tribeni River sections. Of 117 individuals, the number of gharials sighted under the direct observation category was 112. The majority of respondents (129 of 140) during our questionnaire, considered gharial as an important species and displayed a favorable attitude towards gharial conservation. This study concludes that the population of gharial in the Narayani River has increased, as the present population is larger than recorded during previous surveys. Finally, regular surveys and monitoring of gharial in the area are recommended to investigate the status of gharial, the prevalence of any threats and disturbance along the habitat of this important species.

Habitat suitability modelling of Melursus ursinus (Shaw, 1791) (Mammalia: Carnivora) in the Chitwan National Park, Nepal

Abstract
Sloth bear (Melursus ursinus Shaw), one of four species of bear found on the Indian sub-continent, has a geographical distribution across Nepal, India, and Sri Lanka. It is listed as Vulnerable under the International Union for Conservation of Nature Red List of Threatened Species due to the rapid decline of the global population. This decrease in Melursus ursinus presents a need for comprehensive research to predict and understand the distribution pattern. The present study predicts the habitat suitability and distribution pattern of M. ursinus in the Chitwan National Park, Nepal and its buffer areas. The entire study area was divided into 4 X 4 km grids. Within each grid, 10-meter radius plots were sampled for bear signs and habitat evaluation occurred at every 250 meters along a transect (1–1.5 km). Data on direct and indirect signs (diggings, pugmarks, scrapes, and scats) and other habitat use parameters of M. ursinus were collected. The study was carried out during the dry season (January to March 2019) in almost 57 grids of the study area. The calculated habitat suitability for M. ursinus determined that 25% of the total area was suitable, and the remaining 75% was less suitable habitat. Drainage, followed by slope and elevation, were found to be the important variables affecting the distribution of species in the study area and this model was found to be 88.5% accurate in terms of explaining the dependent variables. The findings of the present research will be useful for park managers, researchers, and academicians in the formulation of an appropriate conservation plan for this charismatic mammal species.

Exploring habitat suitability for Bubalus arnee (Kerr, 1792) (Mammalia: Artiodactyla: Bovidae) and its interplay with domestic cattle within Koshi Tappu Wildlife Reserve

Abstract

The wild water buffalo-WWB (Bubalus arnee) holds a significant ecological role within Koshi Tappu Wildlife Reserve, Nepal. Despite its importance, there has been a lack of comprehensive research addressing its distribution, habitat suitability, and interaction with domestic cattle. To address these gaps, this study was undertaken with the primary objectives of elucidating the population distribution of B. arnee within the reserve, mapping its habitat suitability, and evaluating the interplay between B. arnee and domestic cattle in the Koshi Tappu Wildlife Reserve. The study area was subdivided into cells to gather data on B. arnee presence using various indicators such as sightings, dung, and footprints. Interaction between B. arnee and domestic cattle was assessed based on their spatial overlap within and outside a 500-meter radius from observation points. Employing the MaxEnt algorithm, distribution data of B. arnee and climatic variables including maximum and minimum temperatures, mean temperature, and rainfall were analyzed, while land use and cover maps were acquired from the Department of Survey for further analysis. Results revealed a concentration of B. arnee in the southwest region of the Koshi Tappu Wildlife Reserve, with a total of 405 individuals recorded, comprising 26 calves, 6 sub-adults, and 373 adults. The distribution pattern displayed a prevalence of small-sized herds (1–15 individuals) followed by medium-sized (15–29 individuals) and large-sized (29+ individuals) herds. Notably, B. arnee presence was most prominent in grassland areas (approximately 49% of observations), while forested regions accounted for the lowest presence (approximately 10% of observations). Interestingly, domestic buffalo were observed near B. arnee only in a single cell in the southwest section of the study area, while in the eastern cells of the reserve, overlaps between domestic cows and B. arnee occurred within a 500-meter radius. Our study indicated a suitability index greater than or equal to 0.5876, encompassing only about 14% of the reserve's total area. The jackknife test highlighted the influential environmental variables in the model, with annual precipitation contributing around 60.8% and the maximum temperature of the warmest month contributing about 39.20% in determining the distribution of B. arnee. The results underscored the significance of annual precipitation, with a regularized training gain of 0.50, compared to 0.32 for the maximum temperature of the warmest month. In conclusion, this study sheds light on the distribution, habitat suitability, and interaction dynamics of B. arnee within the Koshi Tappu Wildlife Reserve, offering valuable insights for informed wildlife management and conservation strategies.
