Item Aggression and Conflict Resolution in Nicobar Long-Tailed Macaque Macaca fascicularis umbrosus.(SACON, 2019) Partha Sarathi, M.; Kumara, H.N.; ThayumanavanA strong dominance hierarchy with high linearity and steepness in females indicates high competition among the females for food. This pattern was absent in the study with a moderately wrong hierarchy, possibly due to the avoidance of competition for food. This, in term, suggests that food distribution is uniform and abundant for each individual of a small group, which is the foundation of the socio-ecological theory. Furthermore, low competition in the group allows females to form close bonds and exchange affiliative behaviors as recorded in the study. Low monopolization is depicted by low steepness values and under such a regime. subordinate females do not use grooming as currency to gain access 10 food from dominant females.Item An assessment of human-wildlife interactions in the Indus valley, Ladakh, Trans-Himalayas(Wildlife Institute of India, Dehradun, 2012) Chandola, Shivani; Mathur, V.B.The Hemis National Park, in the “Ladakh mountains” Zone 1A, presents such a case of human-wildlife interaction, where the Snow leopard (Panthera uncia) and the Tibetan wolf (Canis lupus chanko) are known to be the major cause of livestock losses to the agro-pastoral communities of this region. On the other hand, the livestock grazing and tourist influx have been cited as challenge for habitat and wildlife conservation. The present study was designed to improve upon the existing knowledge on the human-wildlife interactions in Ladakh. The major objectives of the study were to (i) study the pattern of resource use and its contribution to livelihood of local communities in Trans-Himalayan landscape; (ii) evaluate xi the pattern of conflicts arising from resource use practices by the local communities and its impact on wildlife values; (iii) examine the existing education systems and religio-cultural teachings in their ability to address the conservation issues of the region, and (iv) to examine the existing policy instruments and suggest improvement to minimize such conflicts. The assessment of natural resource dependency and sources of livelihood for the local community residing inside the HNP was carried out during 2005-2006 using data generated through questionnaire surveys, personal observations and secondary sources.Item Spatial ecology and predation pattern of wolf in Spiti Valley, Himachal Pradesh.(Wildlife Institute of India, Dehradun, 2020) Lyngdoh, Salvador; Habib, Bilal; Jhala, Y.V.In the current study focusses on the ecological aspects of the wolves of the Trans-Himalayan landscape. This region is characterized by low prey and growing anthropogenic influences in the form of pastoralist practices. Over time wild prey and predators may have adapted or limited themselves against such anthropogenic influences. With respect to the Himalayan wolf, the strategies that it has developed to cope with seasonality, abundance of prey, habitat choice and traditional pastoralist practices are critical factors that have shaped its long term survival in this region. Therefore, the wolf has probably adapted itself within this environment that is a mosaic of wild and anthropogenic influencesItem Patterns of grazing, natural resources use by local community and their influence on wild ungulate (Ibex) habitats in Pin Valley National Park, Himachal Pradesh(Wildlife Institute of India, Dehradun, 2023) Targe, Kalzang; Adhikari, B.S.; Salvador, LyngdohThis study conducted for a comprehensive study in response to the imperative need for a deeper understanding of the impact of pastoralism on wildlife. The research is centered on the high-altitude rangelands of the Trans-Himalaya, which have a grazing history spanning millennia. The primary goal of this research is to analyse an agropastoral system and investigate its conflicts with wildlife, particularly in relation to the Himalayan ibex. The study is summarized into the following objectives. - To study the changing aspects of local and migratory herders in Pin Valley, - To study grazing patterns of livestock and wild ungulate (Ibex) in Pin Valley, and - To document the natural resource dependency of local agropastoral community in Pin Valley. The study on agropastoral practices and their influence on the wild ungulate ibex in the Trans-Himalaya area employed a variety of methodologies and data analysis techniques. The primary data collection took place between September, 2017 and December, 2019. The research conducted for social aspects in all thirteen villages but only villages dependent on National Park were considered for the analysis. Semi- structured interviews in thirteen villages ensuring representation from different strata, age groups, and genders. Additionally, two focused group discussions were organized in the villages that related with migratory herders with the aim of raising awareness about overstocking and over-grazing's impact on range land resources. To analyse changes in the traditional agropastoral system, data were collected for both the past (pre-2000, before green pea commercialization) and present (post-2017) periods. Informal discussions with local community members were held to understand trends in livestock numbers and composition. Data on agriculture practices were also recorded. The employed various methods to assess Ibex and livestock feeding habits, including direct and indirect observations, bite counts, and microhistological techniques. The findings of this thesis hold practical relevance for land use planning and conservation management strategies. The research findings contribute valuable insights into the interactions between agropastoral practices and wild ungulate Ibex in the Trans-Himalaya area, providing a foundation for guiding conservation and management implementations strategies in the regionItem Playing it Safe Tiger Movement and Livestock Depredation Patterns in Panna Tiger Reserve, Central India(Wildlife Institute of India, Dehradun, 2021) Mohan, Manu K.; Ramesh, K.; Sathyakumar, S.The movement of large carnivores in human-dominated landscapes is not uncommon anymore. While their presence is superficially tolerated or ignored, it is a consistent cause of concern to the people living in its proximity, due to competing interests in sharing of resources and direct threat to human lives. Carnivores incur energetic costs in the form of restricted activity and having to make spatial and temporal activity adjustments. Humans, on the other hand, face losses from livestock depredation and/or loss of lives. Depredation patterns of livestock by carnivores are associated with a variety of factors including habitat structure as well as movement patterns of carnivores in relation to anthropogenic and livestock activity. Hence, deducing movement patterns of the groups in conflict is an important step in understanding the dynamics of conflict patterns at fine scales. Supplemented by models to predict the probability of conflicts spatially which delineates conflict hotspots, site-specific mitigation measures could be devised. To understand such patterns of carnivore movement and relation to livestock depredation events, I conducted this study in a human-dominated region adjacent to the Critical Tiger Habitat of Panna Tiger Reserve in central India from December 2020 to April 2021, within an area of 200 km2. The broad objective was to model the conflict probability based on the proportion of the human-dominated area used by tigers, its intensity of use and spatio-temporal activity within the area, in response to human disturbances. For this, I used intensive camera trap sampling at fine-scale within grids (1 km x 1 km) across the entire study area. Movement parameters of tigers such as displacement and distance to villages in day and night were also analysed by monitoring two GPS-collared tigers in the study area. Occupancy estimates showed 74% of the sampled area being used by tigers, with the relative abundance of a large bodied wild prey (sambar) as the strongest predictor. In addition, a clear positive trend in the relative abundance index of tigers with distance to villages was observed. The temporal activities of the tigers also showed a significant difference in median activity time, shifting towards the night along with moderate diurnal activity at higher distances from villages. The tigers exhibited both crepuscular and nocturnal activity at close distances to villages. The movement range analyses of the tigers using camera traps showed the study area being used by 17 tigers, with 9 of them being adults (>3 years of age). Fixed Kernel Density home-range estimates of the two GPS-collared tigers showed a considerable proportion of their home range areas falling within village boundaries (10%) and an average of 16% of all GPS locations of the tigers fell within 0-100 metres from villages. Despite such high exploratory use of areas within and close distances to villages by sub-adults, there were relatively low incidences of conflict between the tigers and villagers in the study area. Finally, to assess the extent of risk and predict the probability of livestock depredation in the area, Generalized Linear Models were used. The best-fit model indicated a significant negative effect of distance to villages and highway to the probability of livestock depredation. Linear intrusions through highway and forest trails from villages allow easy access to livestock and herders for the utilization of the multi-use buffer areas of the Reserve as well as the tigers to come in proximity to settlements. Corralling of livestock in the night, avoiding free-ranging and grazing of livestock in the identified conflict hotspots, incentivization of alternate source of livelihood by strengthening the institutions such as Eco-Development Committees, along with continuous monitoring of tigers which range close to human settlements are discussed as some of the important measures which can be adopted to decrease the interfaces leading to tiger-human conflict in Panna Tiger Reserve.Item Habitat use by Gaur (Bos gaurus gaurus) and Assessment of Human-Gaur Conflicts Human Modified Landscapes of Nilgiris Forest Division Tamil Nadu(Wildlife Institute of India, Dehradun, 2019) Indira, S.; Sathyakumar, S.Gaur is the largest bovine in the world and is threatened by factors such as habitat loss, poaching, diseases and other anthropogenic stresses. In unprotected landscape, their habitat is confined to small forest pockets which are interspersed with human habitations. This study investigated the use of human-modified landscapes by gaur and how does this potentially increase the negative interaction between human and the animal. Information on ecology of gaur is limited to a few studies conducted within protected areas in India. This study was conducted in the six ranges of the Nilgiris FD, viz., Udhagai North, Udhagai South, Kattabettu, Kotagiri, Coonoor, and Kundha that encompassed an area of 900 km2 during the period January to April, 2019. Secondary data related to conflict and gaur mortality was collected from the District Forest Office to assess the current conflict scenario. To investigate the habitat use by gaur, the study area was divided into grids (2 km x 2km) and an average effort of 1.5 km (+/- 0.5 km) was made in every grid. To evaluate the perception and attitude of people towards gaur and human-gaur conflict, a semi-structured questionnaire was designed preceding the reconnaissance survey. The total crop raiding incidences were 31, human deaths 6, human injury 36, livestock death 4 and property damage 3. Injuries to humans due to gaur attacks appears to be most recorded conflict as indicated by the number of incidents in 3 years, followed by crop raiding, human deaths, livestock deaths and property damage. Areas such as Nunthala, Adhigaratti and Ithalar of Kundha and Udhagai south has high conflict. Areas such as Konvakarai and Bickapathy had medium conflicts and the rest were of low conflict intensity. Most of the conflicts were of crop raiding during the months January to April. In total, 79 gaur sightings 38 dung were recorded in the study area during the study period. Most of the visual sightings were in tea plantation followed by reserve forest, human settlement and cropland. Gaur dung were recorded only in forested habitats. Various groups of people majorly sight gaur in tea plantations than other habitats. Most of the respondents have sighted gaur in and around human habitation during dawn followed by dusk and night hours. Crop Raiding (CR), Human Attack (HA), Traffic hindrance (TRA), Presence in Human Habitation (PRE HH) are the classes of conflicts perceived by the local communities. Majority of the respondents sighted gaur at least twice in a weak. Respondents’ perceived gaur as threat majorly due to have experiencing fear of attack and crop raiding. Gaur is considered as a major threat animal followed by sloth bear, wild pig, leopard and bonnet macaque. Tea plantations are the source for grass and weeds for the gaur to feed on. Proportion of reserve forest is less than other land use classes in the study area. Hence, for the large mammal like gaur can sustain only if it adapts to use the human habitation for food. Investigations on body health condition, home range, population, breeding ecology, behavior, and so on should be made in the future to understand the ecology of the large bovid within close proximity to human. Such research findings will help to make better conservation efforts for site specific and species specific issue. In spite of various wildlife encounters and conflict incidences it is likely that people and animals are co-existing in the Nilgiris. The Forest Department may have to adopt proactive measures for monitoring and management of human-animal conflict in the Nilgiris with more emphasis on gaur. Awareness creation amongst local communities and rapid response by the Forest Department personnel to manage human-wildlife conflict is crucial to avoid injury/ death and other losses/disturbances for the peaceful co-existence of both animal and people.
