. On March 23, 1900, the government proclaimed Yala and Wilpattu reserves under the Forest Ordinance. Initially the extent of the reserve was between the Menik and Kumbukkan Rivers. At that time the reserve did not bear the name Yala. The Game Protection Society (now the Wildlife and Nature Protection Society) was instrumental in establishing the reserve. The forest area between Palatupana and Yala was declared a hunting site reserved only for the resident sportsmen.

Several tanks are there including, Maha Seelawa, Buthawa, Uraniya, and Pilinnawa tanks. Many rivers and streams flow in a southeasterly direction, originating in the highlands of adjacent Uva and central hills.

The study found out that their movements were consistent with behaviour prompted by immediate cues generated by the tsunami waves rather than a response to a "sixth sense".

Tourism

The Yala National Park is the most visited park in Sri Lanka. In 2002 around 156,867 tourists visited the park. Foreigners, especially Europeans, account for 30% of total visitors.
