Sinharaja in Sri Lanka is a pristine tropical rainforest and a UNESCO World Heritage Site, recognized as the country’s last viable area of primary tropical rainforest and one of the most important biodiversity hotspots in the Western Ghats-Sri Lanka region. It harbors exceptional endemism with over 60% of its tree species and many birds, mammals, and amphibians found nowhere else, serving as a vital ecological reserve and living laboratory for scientific research.
