Assessing the distribution pattern of otters in four rivers of the Indian Himalayan biodiversity hotspot

摘要: 1. The Eurasian otter (Lutra lutra), Smooth-coated (Lutrogale perspicillata) and Asian small-clawed (Aonyx cinereus) have all been previously reported from the Indian state of Uttarakhand. However, little information is available about these species’ current distribution in a mountainous region that subject to increasing human-induced stressors (e.g. hydropower plants, pollution, sand boulder mining, destructive fishing techniques, poaching). 2. Due important role otters structuring riverine food webs (particularly taking account their roles as top carnivores), it critical animals receive suitable protection face projected rise temperature, change precipitation patterns, associated river flows this Himalayan biodiversity hotspot. This study assesses four rivers Uttarakhand, basis for informing future conservation actions. 3. Field surveys were conducted (October 2018 – January 2019) (reaches Kosi, Ramganga, Khoh Song Rivers), supported by semi-structured interviews (N=379) with members local communities ascertain qualitative data on views perceptions species. In addition, community-based awareness camps organized youths (N=105), adults (N=115) school children (N=256 covering 10 schools). Habitat suitability maps created using remote sensing data, survey findings Geographic Information System (GIS) provide priority reaches be targeted efforts. 4. This provides interdisciplinary baseline guide decision-makers towards developing targeted, otter-specific program The education programs during resulted proposal set up initiative (CBCI) monitor report sightings area, potentially representing way forward achieving simultaneous ecosystem benefits communities.
