Sinharaja Forest Reserve is a national park in Sri Lanka. It is of international significance and has been designated a Biosphere Reserve and World Heritage Site by UNESCO.
The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1989. The reserve’s name translates as Kingdom of the Lion.
According to International Union for Conservation of Nature (IUCN), Sinharaja is the country’s last viable area of primary tropical rainforest. More than 60% of the trees are endemic to Sri Lanka and many of them are considered rare. 50% of Sri Lankan’s endemic species of wildlife can be found here.
