It is believed that wild buffalos now inhabiting in the dry zone forests and grasslands are decedents of feral domestic stock that have gone wild with the abandonment of Anuradhapura and Polonnaru kingdoms, since no wild buffaloes are to be found in the south of central provinces of Indian mainland. Above theory further says that it was originally imported from plains of Ganges by ancient Sinhalese for the agricultural purposes. Buffalo of true wild state nowadays found only in remote dry zone areas such as Yala and Wilpattu national parks, while in other areas it easily mix and mate with feral populations. Herds seen in grasslands are compose entirely of cows, their carves and young bulls while old and sexually matured bulls lives solitarily in its own demarcated territory defending it from other intruder bulls.
