Description of site:
A tectonic basin in the headwaters of the Lariang River, with extensive permanent swamps and seasonally inundated marshes. The alluvium is of lacustrine origin; the tiny Lake Rano persists as a remnant of a former much larger lake. The extent of flooding probably varies seasonally according to rainfall in the catchment area. The wetland drains west via the Lariang River into the Makassar Strait. As with Lake Lindu (site 89), the swamps are reported to be a source of Schistosomiasis.
Climatic conditions:
The basin is situated in a rain shadow and has a relatively dry tropical climate with an average annual rainfall of 1,500 mm. The wettest months are March-May, and the driest are August-September.
