Gal Oya National Park in Sri Lanka was established in 1954 and serves as the main catchment area for Senanayake Samudraya, the largest reservoir in Sri Lanka. Senanayake Samudraya was built under the Gal Oya development project by damming the Gal Oya at Inginiyagala in 1950. An important feature of the Gal Oya National Park is its elephant herd that can be seen throughout the year. Three important herbs of the Ayurveda medicine, triphala: Terminalia chebula, Terminalia bellirica and Emblica officinalis are amongst the notable flora of the forest. From 1954 to 1965 the park was administrated by the Gal Oya Development Board until the Department of Wildlife Conservation took over administration. The national park is situated 314 km (195 mi) from Colombo.
Associated protected areas
The Gal Oya Development Board established several protected areas to protect the catchment areas of Senanayake Samudraya and several other reservoirs.This also helped to prevent the soil erosion caused by burning of the Thalawa grassland by the villagers. The protected areas established in 1954 are Gal Oya National Park, Senanayake Samudraya Sanctuary, Gal Oya valley north-east Sanctuary, and Gal Oya valley south-east Sanctuary. Together these four reserves accounts for 63,000 ha of land. Administration and protection of the four protected areas, reducing human-elephant clashes and enforcing the flora and fauna ordinance are amongst the duties of the department. Rangers are stationed at four sites: Inginiyagala, Mullegama, Nilgala and Baduluwela. Additionally in 1974 the Buddhangala Sanctuary was also designated. Buddhangala is a monastery with ruins of a stupa and other buildings in the nearby Malwattai area.
