摘要：The smooth-coated otter (Lutrogale perspicillata), a semi-aquatic species, is one of the two species of otters in Pakistan. It is reported as Near Threatened (NT) according to IUCN Red List of Mammals of Pakistan. The species is distributed throughout the Indomalayan eco-zone and occurs along the Indus River and its tributaries in Pakistan. Current study was conducted to evaluate the habitat of the smooth-coated otter in Indus Plains of Pakistan using Habitat Suitability Model (HSM) by incorporating topographic and environmental layers along with species sighting data. ALOS-AVNIR-2 satellite images were used to develop land cover maps of entire study area leading to the development of digital layers in accordance to key habitat features of the species. Within each layer, different variables were assigned suitability values according to the relationship of that indicator with otter habitat. Combining all these layers we derived the suitability of habitat for smooth coated otter in the study area and Habitat Suitability Index (HSI) was calculated. Patches with a suitability value ranging 0.7-1.0 (highly suitable habitat) occupied 13.81% area and suitability value ranging 0.4-0.7 (moderately suitable habitat) occupied 10.71% area while unsuitable habitat for otter (0.1-0.4) is 75.48% of the total study area
