Kudumiriya rainforest comes under Kalawana Forest Range which is directly under the supervision of RFO-Kalawana. Its original extent is 1450 hectares. However some areas have already been encroached and tea has been planted. Recently the forest conservation department has launched a project to restore the rest of the virgin forest by demarcating and planting concrete boundary posts along the boundaries of the forest. The areas which have been encroached for more than five years are to be released and other areas will be reclaimed.
