摘要

Monotypic genera are those that include a single species and, as representatives of distinct phenotypic and molecular diversity, are of particular importance for conservation. In this study, threat assessment of the monotypic Indopiptadenia was carried out, along with potential habitat distribution in its native range. Threat status of I. oudhensis has been assessed as ‘Endangered’ B2ac(ii,iii,iv) + D1. Nineteen bioclimatic and one terrain variables were used to predict the potential habitat of I. oudhensis using the MaxEnt tool. Four major bioclimatic variables determining the habitat distribution were bio13 (precipitation of wettest month), bio9 (mean temperature of driest quarter), bio4 (temperature seasonality), and bio6 (minimum temperature of coldest month), which contributed 36.7%, 13.9%, 13.6%, and 12.1%, respectively for model prediction. The most affecting variable bio13 ranged between 419.60–859.44 mm. The suitable areas were predicted mainly in the Champawat (Uttarakhand) and Pilibhit (Uttar Pradesh) in India and adjacent regions in Nepal, with a total occupancy of 18,637.92 km2. High, moderate, and low suitable habitats were estimated 2629.88 km2, 5304.48 km2, and 10,703.56 km2, respectively. The predicted suitable areas can be utilized for the in-situ conservation of this threatened monotypic species. The protected forest areas in this region, which are under the suitable habitat in prediction analysis, could be the best location for its conservation and further management.
