Scientists from CCMB, Salim Ali Centre, and University of Mysore revealed that lion-tailed macaque populations are rising in non-protected areas of the Anamalai Hills despite long-term risks.
Background
The study tracked 37 macaque groups across 10 rainforest fragments over a 40-year period. It found that population stability is significantly higher within protected forests compared to human-dominated landscapes.
