GLOBAL RECORD: INDIA & KARNATAKA: Karnataka’s Lion-Tailed Macaque Population Highest in World

The latest study was conducted in December 2022, covering  Sirsi-Honnavara and Shivamogga forest divisions.

Karnataka has the world’s largest population of lion-tailed macaques (LTMs) with 41 groups of 730 individuals, according to a study by the Karnataka Forest Department and Coimbatore-based Salim Ali Centre for Ornithology and Natural History (SACON).

The study gave a big boost to conservation efforts as it found that the population of LTMs in the Sharavathi Valley Lion-Tailed Macaque Sanctuary (SVLTMS), spread across Shivamogga and Uttara Kannada districts, has been stable with more groups being added, as compared to the previous study. The earlier study in 2015 had put the population of LTMs at 30 groups with a little over 600 individuals.  

The latest study was conducted in December 2022, covering  Sirsi-Honnavara and Shivamogga forest divisions. Volunteers and forest department staff walked through 72 grid cells in the evergreen forests of the Western Ghats, which span north of the Sharavathi Valley Wildlife Sanctuary and south of the Aghanashini River Valley.

“The study areas were Kyadagi and Siddapur forest ranges in the Sirsi Forest Division, Honnavar, Gersoppa, Bhatkala and Kumta Forest ranges in the Honnavar Forest Division, and Kogar and Kargal forest ranges of the Shivamogga Wildlife Division,” said Vasanth Reddy, Conservator of Forests, Canara Circle, who initiated the study.

“It revealed that Uttara Kannada has been a significant and potential site for the conservation of LTMs, considering the sizable canopy and undisturbed habitat as compared to the north of Sharavathi,” HN Kumara, Senior Principal Scientist, SACON, said. He said the department’s initiatives, like restoration of canopy and forests and insulating high-tension transmission lines that pass through forest areas of Gerusoppa and other places, have helped in the conservation of LTMs.

This is the first integrated LTM assessment exercise for the Sharavathi Valley Sanctuary, covering both Canara and Shivamogga circles. Earlier, the study focussed only on Canara circle. LTMs are the indicators of evergreen forests as they prefer canopy and are rarely seen on ground.
