Flora
Dudhwa Tiger Reserve represents the part of Terai ecosystem in the foothills of the Himalaya. The Sal (Shorea robusta) dominated forests interspersed with tall grasslands and numerous swamps characterize this tract and once this dynamic woodland-grassland-wetland complex harbored a variety of floral and faunal life including several charismatic and obligate species. The landscape witnessed sea change, mainly during the past 150 years or so on account of the long history of forest management, settlement of migrants, changes in land use, agriculture expansion, and various developmental activities. As a result, today the landscape depicts three large forest fragments and several, small and scattered forest fragments amidst human-dominated matrix. Three large forest fragments have been designated as protected areas and are part of ‘Dudhwa Tiger Reserve’, they are Dudhwa National Park (DNP), Kishanpur Wildlife Sanctuary (KWS), and Katerniaghat Wildlife Sanctuary (KAT). Besides several swamps, streams, and rivulets, Sharda and Ghagra are two prominent rivers of the landscape.
