Parsa Wildlife Reserve occupies parts of Chitwan, Makawanpur, Parsa and Bara Districts in central Nepal. The reserve headquarters is situated at Adabar on the Hetauda-Birgunj highway.

The dominant landscape of the reserve is the Churiya hills ranging from 750 m. to 950 m. and running east-west through the reserve. The reserve has sub-tropical forest types with sal constituting 90% of the vegetation. In the Churiya hills and along the streams, chir pine grows. Khair, sissoo and the silk cotton tree also occur. Sabai grass, a commercially important species, grows well along southern face of the Churiya hills.

The reserve supports a good population of resident wild elephant, tiger, leopard, sloth bear, gaur, blue bull, and wild dog. Other common animals are sambar, chital, hog deer, barking deer, langur, striped hyena, ratel, palm civet and jungle cat.

There are nearly 300 species of birds in the reserve. Giant hornbill, peafowl, red jungle fowl, flycatchers and woodpeckers are a few of the other common birds found in the reserve.

Many kinds of snakes including king cobra, common cobra, krait, rat snake and python are found in the reserve due to hot tropical climate.
