Koshi Tappu Wildlife Reserve lies on the alluvial flood plain of Sapta Koshi River in southeastern lowland. Almost all eastern and western embankments of the river define the area.

The reserve was officially gazetted in 1973 giving it a status of the wildlife reserve having an area of 175sq.km. The river Sapta Koshi (largest river of Nepal Kingdom) flows through the reserve that is one of the three main tributes of Ganges.

The mighty river Koshi calm in winter swells up largely in monsoon brining severe flood problems and often changes its course. The depth of the river fluctuates largely from season to season.

Riverine forests dominate the vegetation of the reserve. Sal forest and grassland are also found to the west of the Koshi River. This diverse habitat of different vegetation type and wetland and scrub side makes the faunal wealth of this place incomparable to other protected area system of Nepal of which birds dominate the scenery.

Arna of wild Buffalo (Bubalus bubalis), Blue Bull (Bocelaphus tragocamelus) and Gangetic Dolphin (Platanista gangetic) are the main attraction of this reserve. The lesser mammalian species include varieties of deer, cats, otters, bats, boar etc.
Around 300 species of birds have been recorded in the reserve area that mostly includes waterfowls, birds of prey, waders and other water birds.

Globally threatened “Swamp partridge” (Francolinus gularis) becomes a familiar bird frequently coming on every day list here.
Koshi barrage although not inside but close and south of the reserve has created a vast expanse of water – making this place by far the most important staging point for migrating birds and an all – the – year – round playground for residents.
