![]() ![]() Conservation biologists and managers need a range of both classical analyses and specific modern tools to face the increasing threats to biodiversity. The species habitat information is required to be known by the wildlife managers in order to prepare proper habitat suitability analysis of a species in an integrated scientific manner. Such model is called a habitat (environmental) suitability model. To achieve this one we need a model to predict the suitability of land in a given particular set of land conditions. A wildlife habitat suitability map is defined as a map displaying the suitability of land or water as a habitat for a specific wildlife species. Habitat evaluation is the assessment of the suitability of land or water as habitat for specific wildlife species. states that preservation of wildlife requires a complete knowledge of their spatial requirements commonly referred to as habitat. ![]() Habitat selection is important part of organism’s life history pattern. ![]() Habitat is a place occupied by a specific population within a community population. With the decreasing size of rhino habitat and increasing fragmentation, it has become essential to develop species-specific habitat suitability maps. Revised IUCN categories and criteria, approved by the 40th meeting of the IUCN council has rated one-honed rhino as vulnerable based upon the parameters, namely, population reduction, population estimate, and probability of extinction. Rhinos are in critical demographic crisis primarily by overexploitation through poaching for rhino horn and other products and secondarily by loss of habitat due to expanding and developing human populations. Wilderness areas for Indian rhinos ( Rhinoceros unicornis) continue to shrink and fragment due to multiplicity of natural phenomena as well as ever increasing anthropogenic pressures. This information will help the park managers to conserve rhino and its habitat in Orang NP. The habitat suitability model for rhino shows that 25.13% of the park is most suitable habitat for rhino, 13.62% is moderately suitable and 61.23% is less suitable habitat for rhino in the park. About 8.22% of the park is covered by water body and 6.83% is covered by sandy area. Similarly degraded grassland is covering 15.23% and eastern seasonal swamp forest is covering 1.72% of the park. About 26.06% is covered by wet alluvial grassland and 17.97% is covered by dry savannah grassland. Result indicates that out of total geographical area of the park 25.85% is covered by woodland. A habitat suitability model for one horned rhino was prepared using primary and secondary sources. Satellite imagery of November 2008 was used to evaluate the rhino habitat pattern in the park. It is one of the prime habitats of one horned rhino ( Rhinoceros unicornis) in its distribution range in south Asia. Orang National Park (Orang NP) is one of the important conservation areas in the Brahmaputra valley within North East India biogeographic zone covering an area of 78.8 km 2. ![]()
