摘要：Himalaya and monsoon play the dominant role in determining the nature of wetlands in tropical Asia. There are two distinct eco-climatic zones parallel to sub-Himalayan tracts in north India viz., Bhabhar and Terai (wetlands). Bhabhar is rather narrow and relatively dry strip having low water table, while the Terai is much more extensive and wet. The Terai landscape is a tract between Sarju river and the foothills of the Himalayas covering 11 districts of north-eastern Uttar Pradesh, including Gorakhpur, the region is known for its unique biodiversity and high productivity.
