Abstract
The rich soils of tarai coupled with an annual precipitation over 1300 mm result in great diversity of vegetation in the WLS. The vegetation varies from dense moist tarai sal forest to large open grassland. The vegetation close to Girwa river and its tributaries is characterized by the presence of dense canebrakes. Some artificial regeneration of exotic and indigenous species has also been done in past. The Katarniaghat WLS represents the tarai-bhabhar, bio-geographic sub-division of upper Gangetic plains. As per Champion and Seth’s (1962) classification the following forest types are recognized. (1) The Sal forests: which consti- tute 3C/C2b Moist Bhabhar Sal; 3C/C2b Moist Bhabhar Sal; 5B/C1b Dry Plains Sal. (2) The miscellaneous forests: which constitute 3/E1 Terminalia alata forests;1/E1 Cane brake; 4D/SS1 Eastern Seasonal Swamp forest; 4D/SS2 Barringtonia Swamp Forest; 3/ISI Low Alluvial Savannah Woodland, Bombax-Albizzia; 5B/C2 Northern Mixed Deciduous Forest; 5/E6 Aegle Forest; 5/IS2 Khair-sissoo Forest. (3) Grasslands: which consti- tute 3/ISI Low Alluvial Savannah Woodland, Bombax-Albizzia.
