Ussangoda is a designated archaeological site, situated on the Colombo – Kataragama road near Ambalantota – Nonagama Junction in Hambantota District of Sri Lanka. It is also a nature reserve and is located in the southern turtle breeding zones. Ussangoda is a patch of high ground by the sea and spreads over a significant area. Unlike the rest of the land surrounding, it is only covered with grass and a few pockets of pigmy forests. The summit of Ussangoda area pans like a plateau for a significant length.



The Kirila Kelle wetlands are found a short distance inland from the southern Sri Lankan city of Matara. The wetlands are a part of the Nilwala River basin. They comprise some 750 acres of wetlands. Canals were built by Portuguese Colonialists to mitigate flooding of the Nilwala river into Matara township and aid in the cropping of a further surrounding 6000 acres of rice and other farming. A failed attempt at flood mitigation in the early 1990s has meant that the once arable 6000 acres has now become un-farmable. This reduction in historically arable land has resulted in widespread poverty and associated social and environmental problems for some 35,000 people.
