Impact of COVID-19 on Tourism in Sauraha, Chitwan, Nepal

Tourism destinations in the world are facing different challenges like natural disasters, conflicts, terrorism, economic crisis, and pandemic affecting the various aspect of international tourism needs. The coronavirus was emerged in Hubai, China at the end of 2019, remained a life-threatening outbreak and a major public health issue. In Nepal, the first case of COVID-19 was seen on January 23, 2020, and as part of the containment strategy suggested by WHO, the Government of Nepal imposed lockdown from March 24, 2020, made policies and regulations to control the national and international border (land & air). The Government also requested its citizens to maintain social distance and restrict the movement of people that has affected the Nepalese tourism sector severely. Chitwan is one of the most important wildlife-based tourism destinations of Nepal after the establishment of Chitwan National Park (CNP) and Sauraha is the main point to enter and visit Chitwan National Park. The tourism sector in Sauraha is also pretentious due to the COVID-19 pandemic. What is the status of tourism in Sauraha before and during the Pandemic? The objective of this study is to know how has COVID-19 impacted on tourism in Sauraha in particular and Chitwan National Park in general. For the research, researchers have adopted a qualitative research approach. Primary and secondary data were collected and interviewed 30 respondents representing various sectors of tourism and hospitality in Sauraha. Findings reveal that the outbreak of pandemic has brought huge negative impact by a rapid shutdown on the tourism industry in Sauraha and this has resulted in the loss of revenue, increase unemployment, frustration, and poverty among local people as well as gave positive things like health awareness, consensus on business, time for training and maintenance of infrastructures, etc.

Occurrence of bats in protected areas of Nepal: An update on species richness and distribution records

Bat surveys in 20 Protected Areas (PAs) of Nepal are sporadic and/or had targeted purposively a few localities, therefore, bat diversity from the PAs is yet to be explored. Bat species richness in PAs from two reviews until 2011 are inconsistent. In total, seven surveys have been undertaken in six PAs since 2011. Hence, an update and revision on chiropteran account from the PAs of Nepal is warranted. We reviewed available literatures and museum collection records, and further collated and plotted bat occurrence coordinates into the country and mapped them. In total, 44 of 53 bat species in Nepal have been recorded from 12 PAs. Annapurna Conservation Area (ACA) reports highest species richness (22) followed by Shivapuri Nagarjun National Park and Buffer Zone (SNNP & BZ) (15), Makalu Barun National Park and Buffer Zone (MBNP & BZ) (14) and Chitwan National Park and Buffer Zone (CNP & BZ) (13). In contrast, survey localities are more in CNP & BZ (12), ACA and SNNP & BZ (equally 11) and MBNP & BZ (10). Species richness increased proportionately with higher survey efforts and including more habitat types in respective PAs. Three species: Rhinolophus ferrumequinum, Rh. pearsonii and Rh. sinicus are recorded from six out of 12 PAs. Pipistrellus javanicus (12), Hipposideros armiger (10), Cynopterus sphinx (9) and Rh. sinicus (9) are recorded from maximum number of surveyed localities in the PAs. All the PAs have limited occurrence records. Therefore, intensive surveys are recommended for understanding actual chiropteran diversity to the PAs of Nepal.

Sex-Specific Habitat Suitability Modeling for Panthera tigris in Chitwan National Park, Nepal: Broader Conservation Implications

Although research on wildlife species across taxa has shown that males and females may differentially select habitat, sex-specific habitat suitability models for endangered species are uncommon. We developed sex-specific models for Bengal tigers (Panthera tigris) based on camera trapping data collected from 20 January to 22 March 2010 within Chitwan National Park, Nepal, and its buffer zone. We compared these to a sex-indiscriminate habitat suitability model to assess the benefits of a sex-specific approach to habitat suitability modeling. Our sex-specific models produced more informative and detailed habitat suitability maps and highlighted vital differences in the spatial distribution of suitable habitats for males and females, specific associations with different vegetation types, and habitat use near human settlements. Improving and refining habitat models for this and other critically endangered species provides the necessary information to meet established conservation goals and population recovery targets.

The composition of mixed-species flocks of birds in and around Chitwan National Park, Nepal

Background Mixed-species flocks (MSFs) have been well sampled in the South Asia, but there has been as yet surprisingly little work on MSFs of Nepal, despite a diverse and well-studied avifauna. We surveyed MSFs in two forest types in and around the Important Bird Area of Chitwan National Park in Nepal, between 150 and 800 m a.s.l., to provide a first description of the composition of MSFs in this area. We also aimed to understand which species should be considered ‘nuclear species’, important to forming MSFs or leading them forward. Results In total, we collected records on 222 MSFs that included 100 species, and 6097 individuals. The MSFs were similar to worldwide patterns in being dominated by leaf-gleaning, non-terrestrial insectivores. However, the MSFs were more dominated by canopy species than usual, and did not have a clear gregarious, understory leading species. Rather drongos (Family Dicruridae) and minivets (Family Campephagidae, Genus Pericrocotus) acted as leaders, and a cluster analysis of composition showed one group of large body size MSFs particularly characterized by the presence of the Greater Racket-tailed Drongo (Dicrurus paradiseus). Conclusions Drongos are known to provide both costs and benefits to other flock participants: they are aggressive birds that can steal food, and manipulate other species with their vocalizations, but at the same time they are ‘sentinel species’ that produce information about predation risk other species can use. This study demonstrates that drongos can be considered nuclear species for some types of MSFs, despite the potential costs of their presence. MSFs led by sentinel species thus may form in Asia, as well as in the Neotropics.

Habitat occupancy of sloth bear Melursus ursinus in Chitwan National Park, Nepal

Mammals around the world face serious threats and experience massive decline in their populations and geographic ranges. The sloth bear has become extinct from two of five range countries and the existing population face serious conservation threats. Despite being endangered in Nepal, decades of conservation obliviousness have hindered their conservation and management. We assessed the distribution and habitat use by sloth bears in relation to landscape, environmental, and anthropogenic factors in Chitwan National Park, Nepal. We conducted a sign survey from March-June 2020 in 4*4 km2 grids (n=45) in a checkerboard approach. An observation was spatially replicated four times by recording information in four continuous search trails of 1 km each. We recorded presence/absence of sloth bears, termites, fruits and disturbance in the field and extracted information on tree cover, terrain ruggedness and vegetation index from remotely sensed image of the study area. The data was analyzed using single species-single season occupancy method in PRESENCE software. By using repeated observations these models account for imperfect detectability of species to provide robust estimates of species occupancy. Averaged habitat occupancy estimate obtained from the best models was Ѱ = 0.53 ± 0.04SE with detection probability p = 0.44 ± 0.1SE. Selection of variable based on summed AIC weight from the top models (AIC<2) showed that presence of termites (ƩWi=0.66) significantly influenced sloth bear habitat occupancy. Habitat occupancy was positively influenced by termites followed by fruits, disturbance, terrain ruggedness and vegetation productivity, whereas, it was negatively influenced by tree cover. We suggest that future conservation interventions and action plans aimed at sloth bear management must adequately consider these requirements and issues.

Transmission of Gastrointestinal Parasites in between Deer and Livestock Species at buffer zone located within the eastern part of Chitwan National Park, Nepal

Deer are the hoofed ruminants of the order Artiodactyla and suborder Ruminantia in which infectious disease and parasites are of major concern in their conservation. This specific research helps us to determine the transmission of gastrointestinal parasites between deer and livestock in the buffer zone. The study was conducted in the eastern part of Chitwan National Park from June 2020 to July 2020. Fecal examination for the parasitic load was carried out using Floatation and Sedimentation techniques. 96.49% of the total fecal samples tested for parasitic eggs were found to be positive for the prevalence of gastro-intestinal parasite whereas parasitic prevalence in livestock of Buffer Zone i.e. Sauraha and Bachhauli area was calculated to be 87.30% based on the examination conducted within that same period and same area by the veterinary hospital. Pramphistomum was the most prevalent one in both deer (72.72%) and livestock (52.63%). The finding of this research revealed the higher chances of the exchange of parasites between the deer and livestock. A more advanced study must be done in this sector and concerned authorities should develop and implement effective plans to prevent cross-transmission of parasites between deer and livestock and other wildlife.

Hematological Value of Captive Elephants (Elephas maximus) Around Chitwan National Park, Sauraha, Nepal

Veterinary hematology serves as an important screening procedure to assess general health condition, diagnosis, and treatment of disease. The study was aimed to interpret and establish a set of hematology reference range for Asian elephants kept under private and government facilities of Nepal as no major work has been done till now. Blood samples from 50 elephants around Chitwan National Park, Sauraha was collected and hematological parameters like total erythrocyte count and total leukocyte count were determined. The results showed that the majority of hematological value was in line with the value previously published by different authors. The mean erythrocyte and leukocyte count was reported as 3.32 ±0.93 ×10^6 cell/µL and 10448±335.49 cells/ µL respectively. No sex-associated significant difference was observed in the case of total erythrocyte count whereas total leukocyte counts varied significantly within sex. Our finding revealed no significant difference in hematological parameters between governmental and privately owned elephants. The hematological value of our study can be used as a reference value for assessing the health condition of elephants in Nepal. Further research work should be conducted to evaluate the factors affecting hematological parameters.

Conservation Efforts of Asian Wild Water Buffalo

Asian Wild Water Buffalo with the scientific name Bubalus bubalis arnee is recorded as an imperiled species in the International Union for Conservation of Nature (IUCN's) Red List of Threatened Species wetland-subordinate. More number Wild Water Buffalo in Nepal are found at the Koshi Tappu Wildlife Reserve (KTWR), situated on the floodplain of the Koshi River in Province 1. This species is in danger because of a high anthropogenic pressing factor going from natural surroundings weakening to hybridization with homegrown Buffalo. Various preservation and work mediations have been attempted to shield the biodiversity, especially the wild buffalo populace in the KTWR. The people group-based supportable administration approach profiting both protection and work of neighborhood individuals is important to guarantee the drawn-out preservation of the species. But it is not happening, so the Government of Nepal translocated 18 Wild Water Buffaloes to Chitwan National Park, and the environment is not suitable for them. There is the possibility to translocate Wild Water Buffaloes in the Babai flood plain of Bardia National Park for conservation.
