Chitwan National Park
Located in Sub-tropical inner Terai lowlands of south-central Nepal, Chitwan National Park is 932sq. km in size. The park was designated as a world heritage site in 1984 and is the oldest national park in Nepal.
The park covers a pristine area with a unique ecosystem  of significant value to the world. It contains the churiya hills, Ox-bow lakes and flood plains of Rapti, Reu and Narayani rivers. Approximately 70% of the park vegetation is sal forest. The remaining vegetation types include grassland (20%) reverine forest (7%) and sal woth chirpine 3% the later occurring at he top of the churiya range. The riverine forests consist mainly of khair, sissoo and simal. The grasslands form a diverse and complex community with over 50 species. The Saccharum species, often called elephant grass, can reach 8m in height. The shorter grass such as Imperata is used by the local indigenous people for thatch roofs.

Bardia National park is situated in the mid-far western Terai, east of the Karnali river. It covers 968sq km of land, the largest and most undisturbed wilderness area in the Terai. About 70% of the park is covered with dominantly Sal forest with a balanced mixture of grassland, savanna and riverine forest.

Approximately 1500 inhabitants of this valley have been resettled elsewhere. Since farming has ceased in the Babai valley, natural vegetation is regenerating, making it an area of prime habitat for wildlife . The park provides excellent habitat for endangered animals like the rhinoceros, wild elephant, tiger swamp deer, black buck, gharial crocodile, marsh mugger crocodile and gangetic dolphin.
Endangered birds include the Bengal florican, lesser florican and Sarus crane. More than 30 different mammals, over 200 species of birds, and many snakes, Lizards and fish have been recorded in the park’s forest, grassland and river habitats. A good number of resident and migratory birds are found in the park.

Area: 2330sq. km Established:1992 Location:

The park is sutuated in the sankhuwasabha and solukhumbu districts, bordered by the Arun river on the east, Sagarmatha (Mt. Everest) national park on the west, the Nepal Tibet border on the north and saune kanda (Ridge) to the south. This is the only protected area in Nepal with a strict nature reserve. The park has some of the richest and unique pockets of plants and animals in Nepal, elsewhere it is lost to the spread of human habitation. Stepping up the slopes are a series of vegetation zones starting with tropical Sal forests below 1000m. elevation: subtropical schima castanopsis forests at 1000-2000m, fir/birch/rhododendron forests in the sub alpine 3000-4000m and herbs grasses and rhododendron juniper shrubs in the alpine pastures 4000-5000m

Area: 175sq. km. Established: 1976Location: Koshi Tappu wildlife reserve lies on the flood plains of the Sapta Koshi in Saptari and Sunsari districts of eastern Nepal. The eastern and western embankments of the river define the reserve. Rapid and complete inundation of the reserve to depths ranging from 10 to 300 cm occurs during the monsoon. The sapta Koshi River also changes its course from one season to another. The vegetation mainly includes tall khar pater grassland with few patches of khair sissoo scrub forest and deciduous mixed riverine forest. The reserve offers important habitat for a variety of wildlife. The last surviving population (about 100 individuals) of wild buffalo or Arna is found here. Other mammals are the hog deer, wild boar, spotted deer, and blue bull. The reserve also assists the local economy by providing fishing permits and allowing the collection of edible fruits and ferns in season. 280 different species of bids have been recorded in the reserve. These include 20 species of ducks, 2 species of ibises, many storks, egrets, herons and the endangered swamp partridges and Bengal floricans. The Koshi barrage is extremely important as a resting place for migratory birds. Many species recorded here are not seen elsewhere in Nepal. The endangered gharial crocodile and gangetic dolphin have been recorded in the Koshi river.
