From 650 to 570 in four years, leopard population is on the wane in the State

Kerala has been witnessing a considerable decline in its leopard population as they faced the wrath of rapid development, habitat loss, and retaliatory killing by humans.

Presenting a dismal picture of the big cat population in the State, the fifth cycle of leopard population estimation found the population to have fallen from 650 (with a standard error of 28) in 2018 to 570 (with a standard error of 76) in 2022.

The Status of Leopards in India 2022, jointly prepared by the National Tiger Conservation Authority and Wildlife Institute of India, also detected 63% of leopards to live outside the protected areas in the State and recorded a surge in the number of humanwildlife cases in the Western Ghats landscape including several parts of Kerala.

Ten sites

The study sampled ten sites using camera traps that yielded 3,709 photo captures of 270 individual leopards. While the Periyar

Tiger Reserve showed an increase in leopard population, the Wayanad, and Malayattoor regions experienced a significant decrease.

The Eravikulam National Park, Konni, Ranni, and Vazhachal exhibited consistently low leopard densities, the report said.

Humanwildlife conflict

The number of humanwildlife conflict cases rose from 6,022 in 201516 to 10,036 in 202122. While the northern districts from Kasaragod to Thrissur witnessed the most number of cases, the major conflictprone area was identified as the Wayanad North division, followed by the Kannur, and Wayanad South division. The least number of incidents were reported from the Parambikulam division.

Stressing the need to closely monitor anthropogenic activities in the hotspots, the report recommended steps to understand the population dynamics of leopards and to adopt timely conservation interventions. This necessitated probe into poaching, humanleopard conflicts and the status of copredators.

'Mitigation efforts’

P. Balakrishnan, head, Department of Wildlife Biology, Kerala Forest Research Institute, pointed out that there was no permanent solution to the unfolding crisis of humananimal conflicts. However, the State should focus on mitigation efforts such as adopting predatorproof livestock and animal husbandry practices in forest fringe areas for a possible reduction in humanwildlife interactions.

He proposed steps to prevent cattle from grazing in forests and constructing unbreachable safe sheds for livestock. Waste management should also be intensified in areas that have been witnessing littering of chicken and other wastes that attract stray dogs, which are considered easy prey for the big cats.
