Tamilnadu Forest Type

Forest Type is a unit of vegetation possessing broad characteristics in physiognomy and structure sufficiently pronounced to permit its differentiation from other such units. A good knowledge of forest type is essential for the successful practice of silviculture and forest management.
Forest vegetation is divided into five major groups according to temperature zones. Each major group is divided into type groups on the availability of moisture exhibited in the physiognomic variation like evergreen, deciduous, thorny features etc. The type groups are ultimately distinguished into climatic, edaphic seral and degradation types. The major forest groups present in the state of Tamilnadu are as follows:
