Nestled in the southwestern lowlands of Sri Lanka, Sinharaja Forest Reserve is a globally significant tropical rainforest and UNESCO World Heritage Site. Known for its dense canopy, rich biodiversity, and endemic species, it is the last viable area of primary rainforest in the country. This lush forest offers a glimpse into Sri Lanka’s ecological past and is a must-visit for nature lovers, birdwatchers, and eco-tourists.

Conservation and Threats

• Protection Status: Sinharaja was designated a UNESCO World Heritage Site in 1988 and a Biosphere Reserve in 1978. Its inaccessibility has historically protected it from large-scale logging.
• Community Use: Local communities collect non-timber forest products, such as herbal medicines and sap, sustainably for their livelihoods.
• Current Threats: Despite protection, illegal logging, agricultural expansion, and road construction pose ongoing risks. In 2020, a road project through part of the reserve sparked environmental concerns.
