    Long-term perspective plan: mitigating human-elephant conflict in Rajaji Landscape, Uttarakhand
    (Wildlife Institute of India, Dehradun, 2022) WII-UKFD
    1. The Rajaji Landscape comprising of the Rajaji Tiger Reserve, and the adjoining Forest Divisions of Dehradun, Haridwar and Lansdowne in the state of Uttarakhand (henceforth, The Rajaji landscape) supports a population of about 550 elephants (Elephas maximus) as estimated by the Uttarakhand Forest Department during 201 5. Thus, the Raj aji landscape holds nearly 31% of the elephant population occurring in Uttarakhand. 2. The elephant population in Uttarakhand including that of the Rajaji landscape has been relatively stable and even witnessed marginal growth. However, with growing human population and associated impacts on elephant habitats such as increased resource demands and rapid expansion of physical infrastructure, there has been an increase in the human-elephant conflict (henceforth, HEC). Early detection of the problem and addressing its root causes would be an important conflict resolution strategy. 3. As part of the preemptive conflict management strategy in the Rajaji in landscape, a perspective plan has been envisaged. The overarching objective of the perspective plan is to synthesize available information on the existing HEC in the Rajaji landscape, draw broad inferences on the trends and patterns, and deliberate on different approaches that are appropriate for mitigating HEC. As HEC mitigation strategies are both short- and long -term, the perspective plan is drafted for a reasonably long period of 10 years spanning 2023 to 2033 . 4. The drafting of the perspective plan did not involve any primary background research. However, the plan was prepared using information available in the literature; existing data on elephant movement, home range and conflict collected as part of the WII -UKFD collaborative project (Nigam et al. 2022), and data obtained from the Project Elephant. Further to this, extensive field visits were carried out to corroborate on the important findings obtained from other studies. Furthermore, the plan also draws heavily on other policy documents as elaborated in the report. 5. As elucidated by the first steering committee report of the Project Elephant (Gajatame, 1993), conservation and management of elephants in the Rajaji landscape calls for harboring "viable elephant populations" Perspective Plan to Manage Human-Elephant Conflict in Raja); Landscape (2023 - 2033) in "viable elephant habitats". Often, human-elephant conflict and elephant habitat conditions are intricately linked. In areas where elephant habitat quality is optimal, intensity of human-elephant conflict in the landscape would be comparatively low. Considering this, the perspective plan places emphasis on improving habitat conditions for elephants. 6. It has been observed that owing to adequate protection and voluntary relocation of Van Gujjars from the National Park areas, it is certain that habitat quality from wild life point of view had improved in select areas within Rajaji National Park. However, the highly productive critical ecotone habitats (located in the eco-tone of Bhabar and Terai tracts) in Shyampur and Chidiyapur Forest Ranges of Haridwar Forest Division have suffered major habitat degradation owing to Gujjar settlement in the area and corresponding resource extraction pressures. 7. While the forest cover did not change much in Rajaji Landscape during the period 1985 to 2022, the land-use outside forests have changed substantially. The urban built-up area in particular has mushroomed all around with long-term implications for elephant movement, dispersal and HEC management as well. Unlike in rural areas, Managing HEC in urban areas is far more challenging due to crowd factor. The potential of invoking provisions of Ecologically Sensitive Zone area under Environmental Protection Act, 1986 to disallow urban expansion close to forest boundary need to be explored. 8. Critical corridors like the Chilla - Motichur remained non-functional for a long period. This had resulted in isolation of elephant populations on either side of river Ganga with long-term effects on dispersal, migration and demography of elephants. Nevertheless, huge efforts were invested by the Uttarakhand Forest Department due to which the Chilla - Motichur corridor has been mostly restored. The other critical corridors like the Motichur - Gohri corridor along the Song River would require renewed focus so that this vital corridor can be recovered on time. The Rajaji landscape had also lost a corridor that connected Ramgarh range of the National Park with the Lacchiwala range of the Dehradun Forest Division across Susua river near Dudhli. This was lost largely due to lack of focus as the corridor was not recognized. 9. In the Rajaji Landscape, the natural grasslands along the river Ganga had either been lost (due to human occupation) or degraded. While it would be impossible to recover the once expansive and productive 2 Perspective Plan to Manage Human- elephant Conflict in Rajaji Landscape (2023 - 2033) grasslands along Ganga, it certainly is critical to restore Chilla, Kunaon, and Dassowala grasslands for elephants. Riverine grasslands were important dry-season habitats for elephants in the past. Recovering critical grasslands and restoring their quality would enhance the inherent carrying capacity of Rajaji Landscape to support elephants. Addressing human-elephant conflict in Rajaji Landscape would also be dependent on recovering and restoring habitat in Shyampur and Chidiyapur Forest Ranges. 10. Linear infrastructure expansion including upgradation of existing village roads and district roads in addition to the Highways and concurrent with rapid increase in the vehicular traffic along these roads pose a major long-term threat of habitat fragmentation. Implementing ecofriendly green infrastructure by ensuring habitat permeability would be critical in the Rajaji Landscape to prevent isolation of elephant populations. Isolated elephant populations are predisposed to cause high levels of human-elephant conflict. 11. Physical barriers that separate elephants and people along the forest interface would be crucial to achieve co-existence in the landscape. Without physical barriers at strategic locations, addressing elephant conflict would be difficult. The barriers currently built by the Forest Department along the forest-agriculture interface pose no threat to habitat connectivity. Limitations and opportunities of implementing physical barriers have been elaborated in the report 12. There are 77 places of religious worship inside Rajaji Landscape that draws over 10000 pilgrims every year. Places of religious worship are located in 18 (58%) ranges of 5 (83%) Forest Divis ions in the Rajaji Landscape. While religious tourism has the potential to reinforce cultural underpinnings of nature conservation as practiced in India besides enabling public appreciation of nature, unregulated pilgrimage in wildlife habitats can pose a challenge to elephant conservation as elephants can abandon habitats with chronic biotic pressure resulting in surfacing of human-elephant conflict. Measures to minimize the threats posed by places of religious worship are deliberated. 13. Further, solutions for the sites used for Kumbh mela for festival related activities were also used extensively by elephants as detailed in the report. Hitherto, the temple committees and other religious institutions have not proactively engaged with the forest department in regulating pilgrims and maintaining the integrity of local ecology. Forest Perspective Plan co Manage Human-Elephant Conflict in Rajaji Landscape (2023 - 2033) department with lean headcount of staff cannot be expected to regulate pilgrims and their activities. Given the huge biotic imprint of places of religious workshop on wildlife habitats in Rajaji Landscape, the perspective plan favors vesting substantial responsibility and sharing of resources by committees of the religious worship to maintain the integrity of forests as envisaged by NTCA guidelines issued during 2012. 14. The indiscriminate use of forest roads and trails by tourists visiting places of religious worship poses a huge risk of fatal encounters with wildlife. The situation calls for regulating/restricting use of forest roads and trails by tourists. There are also instances of forest trails being used as roads by clearing vegetation, which need to be curtailed. 15. Finally, the perspective plan favors active dialogue, and engagement with the communities of the Van Gujjars that live alongside elephant habitats. Partnering with local communities and involving them in implementing conflict mitigation strategies would improve the efficacy of the current efforts of Uttarakhand Forest Department.

    Unveiling Torputitora presence in Sikkim streams through eDNA
    (Wildlife Institute of India, Dehradun, 2025) Mane, S.S.; Pant, B.; Kolipakam, Vishnupriya
    Environmental DNA (eDNA) metabarcoding was used to detect the presence of Tor putitora (Golden mahseer) in selected streams of Sikkim. Water samples were collected from six sites based on habitat characteristics conducive to the species survival. The collection of samples was followed by filtration of water samples, isolation of the DNA, PCR and sequencing targeting the COI region were conducted under aseptic conditions. The results confirmed Tor putitora presence at two locations (BR-06 and BR-08) with high certainty (>99%) aligning with previous studies on tis distribution in Sikkim. These results indicate that these streams serve as habitats for Tor putitora. These findings highlight the potential of these streams to support mahseer populations, reinforcing the need for conservation efforts to protect these critical habitats from ecological threats like ecological pressures, including hydropower and linear infrastructure development. This study adds to the expending evidence concerning mahseer distribution in Sikkim and highlights the critical need for conservation initiatives aimed at safeguarding its essential habitats by incorporating appropriate mitigation measures. Continued research and long term monitoring are imperative to evaluate population dynamics and ensure the sustainable management of Tor putitora in the region.

    PAN-India assessment and monitoring of endangered species covered under the Integrated Development of Wildlife Habitats Program )IDWH)- Nilgiri Tahr
    (Wildlife Institute of India, Dehradun, 2025) WII-MoEFCC
    The Nilgiri tahr (Nilgiritragus hylocrius) is an endangered mountain ungulates endemic to the Southern Western ghats of India, predominantly inhabiting montane grasslands. Historically the species occupied a wide range along the Western ghats. However its current distribution has contracted to less than one tenth of its former extent, primarily due to habitat loss, anthropogenic pressure and poaching. Despite its threatened status, comprehensive data on population size, population dynamics and distribution remain patchy and limited. To address this knowledge gap we Standardize double observer method alongside the Bounded count method and also piloted camera trapped based distance sampling in selected sites.

    Conservation status of tiger and associated species in the Terai Arc Landscape, India
    (Wildlife Institute of India, Dehradun, 2004) Johnsingh, A.J.T.; Ramesh, K.; Qureshi, Q.; David, A.; Goyal, S.P.; Rawat, G.S.; Rajapandian, K.; Prasad, S.
    The Indian portion of Terai Arc Landscape (TAL), stretching from Yamuna river in the west to Valmiki Tiger Reserve, Bihar in the east, spreads across five states along the Shivaliks and Gangetic plains. This unique Landscape consists of two distinct zones: (i) bhabar, characterized by a hilly terrain with course alluvium and boulders, and sal mixed & miscellaneous vegetation communities and (ii) terai, characterized by fine alluvium and clay rich swamps dominated by a mosaic of tall grasslands and sal forests. The terai, in particular, is listed among the globally important 200 ecoregions for its unique large mammal assemblage. Over the decades as a result of conquest of malaria, establishment of numerous settlements and consequent increase in human population, this Landscape has become highly fragmented and degraded. This has led to the local extinction of species such as one-horned rhinoceros (Rhinoceros unicornis), swamp deer (Cervus duvauceli) and hog deer (Axis porcinus), for example, west of Sharda river. Despite its ecological richness and faster rate of degradation and species extinction, conservation initiatives are far from desired in this Landscape, perhaps due to inadequate information and lack of coordinated efforts. Given this circumstance, the Wildlife Institute of India (WII) submitted a proposal to Save the Tiger Fund (National Fish and Wildlife Foundation, USA) to carry out a survey of TAL on the Indian side, which is ca. 42,700km2 with a forest area of ca. 15,000 km2. Save the Tiger Fund allotted US $53,500 and an 18-month project was initiated in July 2002. The project objectives were to (i) develop spatial data base on the TAL, (ii) assess tiger (Panthera tigris) and large ungulate distribution and status, (iii) describe the status of the Landscape and its vegetation characteristics and (iv) document the socioeconomic conditions of the local people and major disturbance factors. Indian Remote Sensing (1C/1D) satellite images with the spatial resolution of 188m (WiFS) and 23.5m (LISS III) pixel sizes, and Survey of India topographic maps were used for habitat mapping and other spatial database. The study team surveyed the entire Landscape twice between October 2002 and June 2003 for assessing the status of tiger and other associated large mammal species, and habitat conditions. Extensive sampling of 246 foot transects covering 1001.2km and 1530 circular plots, with nested design, were carried out across the TAL. Demographic and socioeconomic profiles of people were derived primarily from the raw data of 1991 Census. Owing to the applied nature of the project, it was decided to hold a two-day workshop to share the findings and to attain synergy among Forest Officials, NGOs and other conservation agencies for implementation in the field. The study revealed that the TAL contains homogenous vegetation communities of eight broad types, but the structural components vary highly across the Landscape. The tiger habitats on the Indian side are in nine blocks (referred as Tiger Habitat Blocks, THB) and the largest block (ca. 4,000 km2) is around Corbett TR. The forests in Kalsi, Dehradun and Haridwar Forest Divisions in Uttaranchal and Bijnor Plantation Division, Bahraich and Shrawasti Forest Divisions in Uttar Pradesh were devoid of tiger. Thirteen corridors that potentially connect these nine blocks have been identified. When connectivity with the Nepal side is taken into account, the nine THBs can be pooled into five larger units (referred as Tiger Units, TU). Among these, TU II, which is in the bhabar tract and includes Corbett TR, is the most intact one. TU IV (Pilibhit FD-Suklaphanta Reserve-Kishanpur WLS-Dudhwa NP- Bardia NP-Katernighat WLS) is the most extensive terai habitat. Each piece of habitat and connectivity in these Units are crucial and at the same time, are threatened by anthropogenic pressures. Ungulate distribution and relative abundance in TAL corresponds to the high variation or heterogeneity in habitat features. However, the overall status of prey (ungulate) availability is reasonably better in this Landscape, largely owing to the interspersion of Protected Areas between Reserve Forests. The evidence is clear that tiger distribution and its abundance are linearly related to wild ungulate prey such as chital (Axis axis) that has wider spatial distribution. Sambar (Cervus unicolor) and wild pig (Sus scrofa) also contribute substantially in deciding the occurrence of tiger in bhabar and terai regions respectively. The domestic dog was identified as a reliable indicator of disturbance that impedes tiger occurrence. Undisturbed hilly (bhabar) areas such as Corbett TR, which usually have many deep nallahs, providing hideouts and abundant prey (sambar, chital and wild pig) support substantial population of tiger. The terai tall grass habitats, which provide adequate cover, as in Kishanpur WLS and Dudhwa NP, with prey such as chital, pig and swamp deer, is the second best. It appears that in a few years time, tigers may cease to exist in habitats like Sohagibarwa-west (THB VIII), an isolated habitat patch in Uttar Pradesh, which is under enormous anthropogenic pressures. Leopards tend to avoid terai habitats and high-density tiger areas, but are still common in areas extirpated of tiger. Data from the Census of India 1991, for 33 tehsils (units of District) within the study area, indicated that the bhabar, largely west of Sharda river, had significantly lower human density (334/km2) and higher percentage of forest cover (36%). The corresponding figures for terai (east of Sharda river) are 436/km2 and 17% respectively. It appears that the bhabar areas, at present, are in a better position to buffer firewood dependency of the people. Human population increase, ever growing habitat encroachments, poaching, firewood extraction and bhabar grass (Eulaliopsis binata) collection for rope making, stealing of tiger and leopard kills, and boulder mining causing enormous disturbances and fragmentation are the major problems identified. The extensive empirical information (distribution and abundance) collected on vegetation parameters, ungulates and tiger can be used as baseline data to initiate monitoring programmes. In addition, the monitoring should include establishment of adequate number of one-hectare plots and line transects for periodic evaluation of habitat conditions and prey abundance respectively. The study recommends that Chilla-Motichur and Gola river corridors should be established on priority basis and the conservation status of THB IV containing Suklaphanta Wildlife Reserve-Pilibhit FD-Kishanpur WLS should be strengthened. If done, the former will constitute the largest (ca. 8000km2) tiger and elephant habitat anywhere along the foothills of the Himalaya and the latter will ensure the future of one of the finest terai habitats (ca. 1200km2). Initiation of a conservation programme like establishing Rajaji-Shivalik Tiger Reserve is urgently needed to eliminate boulder mining in Yamuna river to ensure the ranging and occurrence of tigers between Shivalik FD and the Kalesar-Simbalbara forests, the western most limit of tiger distribution range. Raising of fuel wood plantations with community participation, use of fuel-efficient chulas, resettling of gujjars (migratory pastoralists) and eight key villages, shifting of one factory and weaning people from bhabar grass collection and conservation education programmes are also recommended. There was a consensus in the two-day workshop held on 6-7 November 2003 in WII that the Nepal model, with a strong scientific foundation and involvement of local people, needs to be adapted for the Indian side of TAL. Cross border cooperation between India and Nepal is a must to ensure the long-term conservation of tiger and its habitat in this Landscape
