Distribution of the Grey Slender Loris (Loris lyddekerianus Cabrera, 1908) in Tamil Nadu, Southern India
The grey slender loris Loris lydekkerianus, one of only two nocturnal primates of India, is found in the southern part of the country. Our understanding of its geographical distribution is largely based on historical records and short surveys, and little is known of its occurrence in southern India today. We sought to establish the relative abundance of this species in 26 districts in the state of Tamil Nadu and the union territory of Pondicherry in southern India. We sighted lorises in 19 districts, and their relative abundance ranged from 0.01 to 2.21/km. The south central districts of Tamil Nadu showed the highest densities of lorises, while the western districts showed the lowest. Based on these results, we recommend increased protection measures for the forest patches of the Eastern Ghats mountains in order to ensure the long term survival of the grey slender loris.
