Maduru Oya National Park

Lore & Background

Maduru Oya National Park lies in the dry zone of Sri Lanka, with a landscape shaped by degradation of Precambrian rock, creating a mature peneplain with rock outcrops and ridges. The park includes five reservoirs—Maduru Oya, Ulhitiya, Ratkinda, NDK, and Henanigala—and tributaries of the Mahaweli and Maduru Oya rivers. The climate is dominated by the north-east monsoon from October to February, with mean annual rainfall of 1,650 mm and temperature about 27 °C.

The park is one of three national parks designated under the Mahaweli Development Project, alongside Wasgamuwa and Flood Plains (Somawathiya National Park was declared separately in 1986 under the Department of Wildlife Conservation). An ancient sluice on the Maduru Oya, made of stone slabs and bricks, was discovered in the 1980s, with the upper sluice dating to before the 6th century BC and the lower sluice believed to be older. Buddhist ruins of shrines, temples, dagobas, statues, and hermitages are found in several locations, and early Brahmi inscriptions from the first to third century AD have been discovered in Kandegamakanda.

The Vedda people, numbering less than a thousand, lived in Kandeganwela, Kotatalawa, Dambana, and other places before the park's declaration. They are traditionally hunters and gatherers, increasingly relying on small cultivation. As part of the Mahaweli Project, Vedda people from several villages were resettled in Henanigala.

Reader's Guide

Maduru Oya National Park holds significance as a protected area that balances wildlife conservation with human habitation, particularly for the Vedda people, Sri Lanka's indigenous community. The park's designation under the Mahaweli development project highlights the intersection of large-scale infrastructure and environmental protection. Its role as a catchment for five reservoirs underscores its importance for water management in the dry zone. The park's biodiversity includes threatened species such as elephants (150-200 individuals as of a 2007 study), sloth bears, leopards, and water buffalo, as well as endemic flora like the rare tree Vatica obscura. Conservation challenges include encroachment, poaching, illegal timber felling, invasion by alien species Lantana camara, and conflicts between wildlife and settlers. The proposed Nilgala jungle corridor aims to link Maduru Oya with Gal Oya National Park for contiguous wildlife habitat. The park's cultural heritage, including ancient sluices and Buddhist ruins, adds archaeological value, while the presence of the Vedda community raises issues of resettlement and cultural preservation.
