Sinharaja,The Magical Creation of Mother Nature


                                                                           



Sinharaja, a tropical rain forest which contains plenty of natural resources , natural secrets,biodiversity etc.
Sinharaja was consider as one of the major natural habitat in Sri Lanka. It is located at Southwest  part of the island,also its belongs to Sabaragamuwa and southern provinces.This magical rain forest spread among Galle, Mathara and Rathnapura Districts. Sinharaja forest is treasure trove of Rare flora and fauna.a considerable amount of villages depend on the forest's products for their income.

If we consider about how Sinharaja forest gets its name,actually  it's based on nice folk story. there was a threatening lion that lived in a cave situated in a place named "Sinhagala". The lion is said to have preyed on all animals living around "Sinhagala" and have posed deadly threats to people walking across the jungle . When the trouble from the lion began to increase, a brave youth called Lanka tactfully stoned the advancing lion to death.Even in today there is a small village call "Lanka Gama" in sinharaja forest.

Actually Sinharaja is a wonderful creation of mother nature. Sinharaja is a wet ever green tropical monsoon rain forest. At present world have only hand full of tropical primary rain forests. As Sri Lankans we can proud having  of this kind of  beautiful mysterious rain forest. Some parts of this forest reserve  didn't got any anthropocentric activities ever on its life. Those Areas where preserved as primary forest patches. with the aid of this primary we can find origin or wild type  of some plants, because of this reason we can named Sinharaja forest as a natural gene bank.
Sinharaja forest was declared as a forest as forest reserve on 1875 under the waste land ordinance. In 1978 it is declared as biosphere reserve.  Sinharaja forest became first natural world heritage site after it is declaered as man and biosphere reserve by UNESCO on 1989.

Artocarpus nobilis,Mangifera zeylanica (s-ataba), Mesua nagasariyum (s-na) are common in canopy layer of the Sinharaja forest.Due to continues connection of  tree of this layer solar radiation is reduced to the ground because of that plants of ground layer compete for the sun light, due to that we can observed equal size plants in ground layer. Plants which their height is ranged between 25-8 m are belongs to sub canopy layer e.g. Wormia triqvera (s-diyapara) , Dillenia retuse (S-godapara).
