Why are there no tigers in Sri Lanka?

There are no wild tigers in Sri Lanka, meaning the Sri Lankan tiger population stands at zero. The primary reason for this is the formation of the Palk Strait near the end of the last Ice Age, which severed the land bridge to the Indian subcontinent and permanently prevented migration.

While fossil records from Ratnapura indicate that tigers briefly inhabited the island approximately 16,500 years ago, this isolated Sri Lankan tiger population went extinct. Subsequently, the stretch of ocean has prevented Bengal tigers from moving south from mainland India to repopulate the region.

As a result of this geographical isolation, the Sri Lankan leopard (Panthera pardus kotiya) evolved with no competition. It ultimately became the island’s undisputed apex predator, filling the ecological niche that tigers typically occupy across most of Asia.
