This is the smallest (175 sq.km.) and newly promoted wildlife reserve for safari trip in Nepal’s sub- tropical Terai belt. But still, it is the largest wetland area (Ramsar site) in Nepal, draining 7 major rivers from the great Himalayan belt into the Sapta Koshi (7 Rivers). The reserve provides the best adventure of spotting fresh water dolphins. The habitat is a combination of scrub grassland and deciduous riverine forest, with over 280 species of birds recorded so far, including 20 species of duck, ibises, black- necked storks, Indian skimmer, swamp francolin, herons, egrets, Bengal floricans and many other exotic and migratory waterfowl not found elsewhere in Nepal.
