4. The Gangetic Plain
The flora of the Gangetic plain has been substantially transformed by human activities and cultivation of crops. The vegetation type, however, ranges between the semi-arid shrubs of the Aravalli region to evergreen mangroves of the Sundarban Delta. Sal and Arjun of the Tarai region of Bihar and West Bengal are the representative species of the primordial vegetation. The vegetation of Uttar Pradesh is mainly dry deciduous type which changes to moist deciduous type, in
Bihar and West Bengal. Sheesham, neem, mahuwa, jamun, acacia, ber, bel, etc. are the examples of this type of vegetation. In addition to these, there are numerous types of grasses found in the Gangetic Plain.
