The Dark Sitana (Sitana fusca) is an agamid lizard endemic to Nepal, only known from its type locality in Madhesh province. Due to increased habitat loss, forest fragmentation, and urbanisation in its type locality, this species is now ‘critically endangered’. There is also very limited
information on its ecology and distribution. To help this, the Nepal Conservation and Research Center
(NCRC), with support from The Rufford Foundation, Auckland Zoo, and Katie Adamson Conservation Fund, initiated a research and conservation project focusing on the Dark Sitana. Outreach and community engagement programmes, conducted jointly by NCRC and the Mithila Wildlife Trust, were also major components of this project. During these sessions, we taught students in ten schools and in three peri-forest communities (communities that live immediately adjacent to the forests, and are dependent on forest resources). A total of 671 students (268 boys and 403 girls) and 71 community members attended our sessions, wherein a ‘conservation poster’ of the Dark Sitana was also distributed. As a result of our outreach programmes, people, who previously had negative perceptions about this species, understood that these lizards are an important component of their ecosystem, and that they do not harm humans (in many Nepalese societies, lizards are considered to be relatives of snakes and deadly venomous; folklores also portray these reptiles to be lazy and dishonest).

Some of the peri-forest community members also promised to inform us whenever they spotted the
species to help understand its distribution better.

We found that our sessions were well-received among students and community members. Word spread and we started receiving invitations from several other schools for outreach sessions and requests for printed copies of the poster. Such interest and enthusiasm makes us look forward to conducting such sessions more often, including during Nepal’s national wildlife week, in collaborations with other organizations on ground. After all, the goal is to share knowledge and develop sustainable conservation measures for the Dark Sitana in Nepal.

Species composition and habitat associations of birds around Jhilmila Lake at Western Chure Landscape, Nepal

Authors: Dipendra Adhikari, Jagan Nath Adhikari, Janak Raj Khatiwada, Bishnu Prasad Bhattarai, Subarna Ghimire, Deepak Rijal

Abstract: Wetlands support around 27% of birds in Nepal, however, there is a paucity of information about bird diversity and the wetland habitat of Western Chure Landscape Nepal. The “point count” method along transects was carried out to evaluate the species composition and habitat associations of birds. A total of 2,532 individuals representing 152 species (winter: N = 140 and summer: N = 91) from 19 orders and 51 families were reported from Jhilmila Lake and its surrounding area. The number of birds was reported to be significantly higher during winter than in the summer season. The species diversity was also higher in winter (Shannon’s index (H) = 4.38, Fisher’s alpha = 30.67) than in summer (H = 4.21, Fisher’s alpha = 34.69) as this area is surrounded by oldgrowth forest that provides available habitats for forest, grassland- and wetland-dwelling birds. This lake is an example of a wetland present in the Chure area that plays an important role in the conservation of biodiversity along with birds. Hence, we recommend its detailed study in terms of biodiversity and water quality.

Diversity and habitat associations of non-volant small mammals in forest patches of Kathmandu Valley, Nepal

Authors: Sital Budhathoki, Jagan Nath Adhikari, Binod Bhattarai, Dipendra Adhikari, Bishnu Prasad Bhattarai

Abstract: Forest patches in urban areas can have the potential to provide shelter, resources, and breeding space for small mammals. This study aimed to explore the diversity, abundance, and habitat associations of non-volant small mammals in forest patches of Kathmandu Valley. Three sites were selected for the study: Ranibari Community Forest, Swayambhunath Hillock, and Coronation Garden of Tribhuvan University. The roost survey, line transect survey and direct observation methods were used for the study. The field survey was conducted in June–July 2019. In those selected sites, 250 m transects were laid and 25 live traps (Local, Sherman, and Tube) were set for capturing small mammals. Trapped individuals were measured, marked, and released at the site. From a survey of 600 trap nights, 61 individuals representing six species, four families and three orders were identified. Asian house shrew (Suncus murinus) was the most dominant species. Abundance of small mammals was higher in Ranibari Community Forest whereas Coronation Garden had the lowest abundance of non-volant small mammals. Small mammal distribution pattern was clumped in study areas owing to the uneven distribution of resources in the natural environment. Species response to five environmental parameters (distance to settlement, road, water, open canopy and closed canopy) showed significant relation in Ranibari Community Forest (F=2.446, P=0.018) and Coronation Garden (F=2.75 P=0.05), whereas it was insignificant in Swayambhunath Hillock (F=1.60 P=0.17). These results suggested that diversity, distribution, and abundance of small mammals in urban forest patches are influenced by habitat types and environmental parameters.

Nepal’s BP Highway threatens endemic, critically endangered lizard, Dark sitana

The dark sitana, a lizard endemic to a town in Nepal, is critically endangered by the loss and degradation of its habitat due to the BP Highway and unplanned urban development.

The critically endangered dark sitana (Sitana fusca), a rare lizard that hasn’t been reported anywhere else in the world, faces a host of challenges for its survival, most of them triggered by the highway development. “The main threat to its existence is the loss of its habitat, which has been fragmented and degraded by the construction of the BP Highway,” says researcher Santosh Bhattarai, who is pursuing a Ph.D. in herpetology.

Himalayan Frogs Conservation Initiative in Nepal

The frogs of Nepal’s Himalayan region are under significant pressure from climate change, habitat loss and because they are hunted and eaten by local people.  In addition, the historical focus of conservation efforts in Nepal has been on large iconic mammalian species such as tiger, rhinoceros and elephant.  A clear conservation focus is required for Nepal’s frogs, particularly in the mountain areas, where the effects of climate change are most extreme.   This clear focus is prevented by a lack of understanding of the kinds of frogs present in the area, their relationships to one another and their relationships to groups outside of Nepal. It is likely that there are several species of frogs present in this region which have not yet been recognized.  Without knowing which species are present, or how they are related to other groups, it is difficult to establish meaningful conservation approaches for species.

The overarching goals of this project to understand and establish knowledge gaps on Himalayan frog species of Nepal. This project will use integrative approaches such genetics, morphomtrics and bio-acoustics to identify different species, to establish a clear understanding of the relationships among a particular group of frogs present across Nepal’s Himalayan region.  We will also explore hunting pressures on frog species.  

Re-print of Dark sitana poster

We printed 1000 copies of Dark sitana poster for conservation outreach in schools and communities in Dark sitana range sites. During our school and community sessions, we taught conservation importance of Dark sitana and other reptiles of the region. We also distributed a copy of the poster to the session attendees. We also circulated our photographs of our outreach sessions in social media. We received overwhelming responses for poster and session requests within Dark sitana range and beyond Dark sitana range where other species of sitana are found. Due to high demand of poster and session requests in schools and communities, we are printing again 1000 copies of the same poster.

Dark sitana poster contestants awarded

Dark sitana “conservation poster” contest was announced at our social media platform herpsNEPAL. A total 22 contestants designed and submitted the poster. The idea of the photo contest was to make members of herpsNEPAL aware about Dark sitana and get better poster design insights. Among all the contestants, two winners (Ms Shreeya Manandhar and Sanej Prsad Suwal) were selected as the best poster designers. The best poster designers were awarded with Dark sitana conservation T-shirt. Ms Shreeya Manandhar is a postgraduate student of Kathmandu University and Mr. Sanej Prasad Suwal is affiliated to NCSC- an NGO based in Kathmandu.

Ecological assessment of endemic skink species in central Nepal

The Himalayan region is a biodiversity hotspot with a unique biogeography that has influenced the diversification of many taxa. Three endemic skinks (family: Scincidae) were discovered in central Nepal: Mahabharat skink (Ablepharus mahabharatus), Nepal skink (Ablepharus nepalensis) and large ground skink (Scincella capitanea). Information on their distribution, population abundance, habitat use and resource partitioning with sympatric species is lacking.

Reptiles are susceptible to environmental and anthropogenic changes and have limited dispersal capabilities. They are particularly sensitive to habitat modifications and climate change, both of which are occurring rapidly in the Himalayan and hilly regions of Nepal. No dedicated study on Nepalese endemic skinks has occurred. This project will fill a knowledge gap by conducting ecological assessments to provide details on current distribution, habitat use and micro habitat selection, population abundance and threats impacting the survival of these endemic skinks to inform conservation strategies.

World wildlife day 2023 marked for Dark sitana (Sitana fusca) conservation in Nepal

Every year world wildlife day is celebrated on 03 March to commemorate the conservation efforts. Nepal Conservation and Research Center (NCRC) and Mithila Wildlife Trust (MWT) jointly marked the day in Madhesh province, Nepal with two different activities for Dark sitana (Sitana fusca) conservation aligning the theme of world wildlife day “Partnership for conservation” among women group and school students.

The Dark sitana (Sitana fusca) is a critically endangered lizard endemic to Nepal, so far only known from Madhesh province of Nepal. Therefore, to raise awareness on ecological and conservation importance of Drak sitana, we conducted an awareness session for peri-forest women group of Dudhpani community forest, Dhanusha. We also explored the local names and beliefs to respect the indigenous perceptions towards reptiles. We presented slides and video session whether they are aware of the presence of Dark sitana in their community forest or not. We distributed a copy of printed poster of Dark sitana to the participants of the session.

Session with students

We also marked world wildlife day with students at Mahadev Adharbhoot school to imprint conservation importance of Dark sitana and other wildlife in young minds. We found students were very keen and inquisitive to learn about biodiversity around them. We displayed the video of Dark sitana and other wildlife and presented about their behaviour, ecological significance and how students could be the part of the larger conservation arena.
