Classification of forest according to their density - definition
Forests are classified into three categories according to their density. 1. Dense forest: This type of forests are found in some mountainous region and regions with heavy rainfall. About 59% of the total area of forests is this type of forests. 2. Open forests: In India, we have 40% of the total forest area, covering open forests. 3. Mangroves: These forests (tidal forests) are found on the coastal areas of India. The mangroves are less than 1% in India.
