Study on distribution and relative abundance of large mammals and impact of human disturbance in and arond Mehao Wildlife Sanctuary, Arunachal Pradesh
(Wildlife Institute of India, Dehradun, 2023) Ahmed, Arif; Gopi, G.V.
The current study was started to gather baseline data on a few ecological factors (Diversity, distribution, relative abundance, Activity pattern and habitat preference) of selected large animals in Mehao WS. Northeast India. The study period was November 2017 to 2020. The objectives of the study are 1. To estimate the relative abundance and occupancy of selected large mammals in and around Mehao wildlife sanctuary. 2. To develop Habitat suitability model for selected large mammals in and around Mehao WS 3. To analyse the land use/land cover change pattern and to identify the main driving factors.
Aspects of ecology of large carnivores and their prey in and around Dibang Wildlife Sanctuary, Arunachal Pradesh, India.
(Wildlife Institute of India, Dehradun, 2021) Adhikarimayum, Aisho Sharma; Gopi, G.V.
The conservation of large mammalian carnivore is prioritized as it acts as keystone species across diverse zones of habitat around the globe. They play an important role in regulating and maintaining the abundance of ungulates, in turn influencing the functioning of the ecosystem. In the last few decades, large carnivore’s population have been declining due to anthropogenic activities such as habitat destructions creating forest patch, illegal trade and hunting on wildlife. These threats posed a challenge in the conservation and management of large mammalian carnivores. The co-existence of large carnivores is occurring in many places in the wild due to the availability of less prey base, habitat fragmentation and high human interferences. Thus, the understanding of ecology of large carnivore and their prey species particularly on habitat selection, prey-predators’ relations in aspects of distribution and abundance, such ecological data can be useful to evaluate not only their habitat requirement but will also aid in long term management of wildlife and conservation of their habitats. So, efficient conservation and monitoring of large carnivores such as tiger and wild dog (dhole) is required for the assessment of complex mix of ecological, ethical and symbolic inter-relationships. The study was conducted at Dibang Wildlife Sanctuary; it covers an area of 4149 km2 and situated in Dibang Valley district of Arunachal Pradesh. The tiger is culturally considered as a brother by the local Idu Mishmi community who live in the Dibang Valley district in Arunachal Pradesh. Though the local community has long been claiming about the presence of tigers in the region, unfortunately, no efforts were made by the line departments, academicians, or conservationists to assess and monitor the tigers, their prey, and habitat in Dibang Wildlife Sanctuary. This preliminary study was carried out after the rescue of tiger cubs from the district in Angrim Valley during December 2012. The rescued tiger cubs were the first-ever record of a tiger from the sanctuary. The primary objectives for the aspects of ecology of large carnivores and their prey in and around Dibang Wildlife Sanctuary are: a) To estimate the abundance of large carnivores in and around the Dibang Wildlife Sanctuary, b) Assess the abundance of wild prey in and around the Dibang Wildlife Sanctuary, c) Assess the food habits and prey selectivity of large carnivores in and around the Dibang Wildlife Sanctuary, and d) To quantify the extent of human-wildlife interaction in and around the protected area. An intensive camera trapping exercise was carried out during October 2015 to June 2017 in the Dibang Wildlife Sanctuary and adjoining landscapes to monitor large carnivores and their prey species. Dibang Wildlife Sanctuary and its adjoining landscape harbors sizable population of large carnivores such as tiger and wild dogs. The study has reported the first photographic evidence of tiger presence from the community forest of Mishmi hills range in Dibang Valley District at an altitude of 3630 m amsl and it is the highest record from the Indian part of the Eastern Himalaya Biodiversity hotspot. This study has generated baseline information on tiger, wild dog and prey species in Dibang Wildlife Sanctuary and adjoining landscape. Tigers do not necessarily use only the protected areas; they use the community forests outside the protected area as well.
Assessing the Patterns of Human-Wildlife Compensation Around Pakke Tiger Reserve Arunachal Pradesh
(Wildlife Institute of India, Dehradun, 2019) Langlang, Luxmi; Das, Abjijit; Gopi, G.V.
Of all the types of interactions between humans and wildlife, human-wildlife conflict (hereafter HWC) poses a significant challenge to conservation efforts and species survival. This conflict may be manifested with a range of interactions with more negative actions being killing and injury to wildlife and humans while more neutral actions being internalizing costs of living with wildlife. People living in and around protected areas interact closely with wildlife. The negative interaction may be in the form of crop raiding, livestock depredation, property damage or death and injury to human. Thus, such interactions may result in economic loss to people and may create animosity against conservation through reduced public support and retaliatory killing. Further peoples’ perceptions towards HWC may vary by species, especially as large and potentially dangerous animals such as tigers and elephants are seen as a threat to farmers’ livelihoods. In this context, I assessed the patterns of HWC around Pakke Tiger Reserve to identify conflict species and hotspots of conflict. I tried to understand the constraints about compensation in terms of the gap between self-reported conflict and conflict reported to forest department. I also focussed on understanding the perception of people towards commonly found wildlife in the reserve with the help of attitude score. My study was carried out in 41 villages where I interviewed 327 households around Pakke Tiger Reserve. I used a semi-structured questionnaire and open-ended questions to understand the pattern of conflict, compensation issues, attitude towards different species and mitigation strategies most commonly used. Perception data was also collected. Crop damage (mostly by wild pigs, macaques and rodents) was reported as the most prevalent type of conflict around PTR followed by livestock depredation (mainly by wild dogs, tigers and leopards). Property damage and human death and injuries were reported to a lesser extent. Twelve different mitigation strategies were commonly used against crop raiding and livestock depredation. Night patrols and sound were used to keep animals away from fields. Livestock’s were mostly grazed in the forest, and hunting of predators was the most common mitigation strategy against livestock depredation.
