According to Champion and Seth Classification, 18 forest Types are present in Odisha. However broadly, based on the relief, rainfall and vegetation types, the forests of Odisha are divided into the following 4 major types:
- Northern Tropical Semi-evergreen Forests: These occur in the lower hills and valleys above 600 m elevation in the forest divisions of Mayurbhanj, Dhenkanal, Athgarh, Puri, Nayagarh, Parlakhemudi, Koraput and Kalahandi. While the top storey trees are deciduous and remain leafless for a short time, the second storey is evergreen. The important tree species are: Arjun, Mango, MankarKendu (Diospyros embryopteris), Champa, Rai, Manda and Nageswar.
- Tropical Moist Deciduous Forests (Also known as Monsoon Forests): These occur in the lower elevations in Mayurbhanj and Keonjhar districts and the districts bordering on Madhya Pradesh and Andhra Pradesh. The top canopy is formed by Sal (Shorea robusta) and its allies Asan, Piasal, Kurum, Kangra and Dhawra and Daba bamboo (Bambusa arundinacea).
- Tropical Dry Deciduous Forests: They occur in the drier central and western areas in parts of Balangir, Kalahandi, Sambalpur, Khariar, Deogarh and Gobindpur divisions. Teak instead of Sal, and Salia bamboo (Dendrocalamus strictus) instead of Daba bamboo predominate in these forests.
- Tidal Mangrove Forests: These are limited in extent, scattered and confined to the sea-coast, especially in BhitarKanika and the Mahanadi delta. The characteristic tree species are Karika (Bruquiera), Sundari (Heritiera), Bani (Avicennia), Rai (Rhizophora), Guan (Exocaria), etc. As Hental (Phoenix paludosa) grows here abundantly in clusters, the mangrove forests are locally called Hental van.
