Prioritizing Remnant Forests for the Conservation of Mysore Slender Lorises (<Emphasis Type="Italic">Loris lyddekerianus lyddekerianus</Emphasis>) in Karnataka,India Through Estimation of Population Density

Information on a species’ distribution, abundance, and habitat requirements is important for formalizing a comprehensive management and conservation strategy. This becomes an even higher priority when the distribution of a species lies largely outside demarcated protected areas for wildlife. We used line transect distance sampling to estimate the density of an arboreal, nocturnal, and threatened primate, the slender loris (Loris lyddekerianus lyddekerianus) across diverse habitat types including both reserve forests and production landscapes in the southern part of the state of Karnataka, India. Abundance estimates varied from 0.16 individuals/ha in Devrayandurga State Forest to 2.57 individulas/ha in Ippadi State Forest, with the mean density estimate being highest in the Forest Division of Tumkur, at 165 individuals/km². Based on density estimates for the survey regions, their current habitat status, and perceived threats, we identify Ippadi, Ujjani, Devrayandurga, and Savanadurga state forests as priority areas for conservation of the slender loris. We propose that these areas be declared protected. The required management intervention is preventing further degradation of the habitat and enhancing canopy contiguity to facilitate loris movement.
