The Sinharaja forest is the only undisturbed rainforest left in Srilanka.It is about 9000 hectares in extent.Many of the plants are very rare.Over 60% of the tree species are found only in the lowland wet zone of Srilanka.If these species of trees are allowed to get destroyed,the world would lose them altogether.So it is important that much effort is made to conserve this rich,valuable and fragile habitat.
The Sinharaja rainforest is the largest rainforest reserve in Srilanka.In 1840 Sinharaja became a crown property.In 1988 the Sinharaja was made a National Wilderness area.In 1989 UNESCO included the Sinharaja Forest in the World Heritage list,as the first National Haritage of Srilanka.
The Sinharaja forest is home to many rare animals,birds,butterflies,insects,reptiles and trees.Ferns and mosses grow well as the climate is humid because of heavy rainfall.
