Accepted Answer

Wildlife researchers monitoring the Sri Lankan Leopard (Panthera pardus kotiya) across Wilpattu National Park deploy grid systems of automated infrared camera traps along sandy forest roads and villu perimeters. Utilizing spatial capture-recapture (SCR) statistical models based on individual rosette spot patterns, DWC scientists estimate a healthy regional leopard population. Unlike Yala where vehicles crowd sightings, Wilpattu’s dense monsoon forest cover and expansive road network (over 1,300 sq km) result in wider territorial spacing and lower human-leopard visual frequency.

Camera traps also document nocturnal activity among elusive species, including pangolins, rusty-spotted cats, and sloth bears.

Research cameras are secured inside locked steel housing boxes mounted to mature trees to prevent theft or damage by curious elephants.

Full-day safaris entering through Hunuwilgama gate offer the best opportunity to explore remote interior villus where leopards hunt undisturbed.
