Ecosystem and Species Habitat Modeling for Conservation and Restoration

Abstract

The natural populations of Oroxylum indicum—an important medicinal plant—is declining due to habitat loss and overexploitation. Modelling its potential distribution area can help in its conservation. We used maximum entropy (MaxEnt) model to predict the potential distribution of the species and identify the factors determining its niche. The model performance was consistent and good with area under curve (AUC) value of 0.827 and true skill statistic (TSS) of 0.658. The major environmental variables determining the niche of the species were precipitation of the warmest quarter (49.7%) and annual mean temperature (19.6%). The model predicted 6.01% as highly suitable, 23.29% as moderately suitable and 70.70% as least suitable. The model predictions could be is useful in identifying the critical habitats for conservation and restoration of important plant resources.
