The Pinnawala Elephant Orphanage was established by the Sri Lankan Department of Wildlife Conservation in 1975 for feeding and providing care and sanctuary to orphaned baby elephants that were found in the wild. The orphanage was located at the Wilpattu National Park, then shifted to the tourist complex at Bentotaand then to the Dehiwala Zoo. From the Zoo it was shifted to Pinnawala village on a 25-acre (10 ha) coconut plantation adjacent to the Maha Oya River.
The orphanage was established to feed, nurse and house young elephants found abandoned by their mothers. Young elephants sometimes fall into pits and ravines in their quest for water during drought period. Other orphans have been displaced from their wild habitat by development projects or have been found abandoned before weaning, diseased or wounded.
There are 48 mahouts (handlers) who take care of the elephants. The female and young elephants in Pinnawala range freely as a herd during the day in an area of a few acres. They are herded about .5 km (0.31 mi) twice a day to drink and be bathed in the river. At night, the females are individually chained in stalls. Adult males do some light work such as transporting feed. They are chained and managed individually. Calves born in Pinnawala are not bottle fed, but a few from ETH are kept at Pinnawala and bottle fed as a tourist attraction.
The elephants are fed in their stalls. There is very little food they can gather from the premises of the orphanage except some grass. Large quantities of jackfruit, coconut, kitul (sugar palm), tamarind and grass, brought in daily, form the bulk of the elephants food. Each adult animal is given around 250 kilograms (550 lb) of this green matter per day and around 2 kg (4.4 lb) from a food bag containing rice bran and maize.
