ecoregions‚ such as theshola forests‚ also exhibit extremely high rates of endemism; overall‚ 33% of Indian plant species are endemic. India’s forest cover ranges from the tropical rainforest of theAndaman Islands‚ Western Ghats‚ and Northeast India to the coniferous forest of the Himalaya. Between these extremes lie the sal-dominated moist deciduous forest of eastern India; teak-dominated dry deciduous forest of central and southern India; and the babul-dominated thorn forest of the central Deccan and
