The forest function/ecosystem education exhibit will focus on the rich variety of ecosystems to be found on Borneo, ranging from the higher montane areas, through hill and lowlands, with peat swamps all the way to the coastal mangroves. The important functions these forests fulfill as water catchment areas, nurseries for fisheries, and their rich varied biodiversity will be highlighted.

The Sungai Wain Protection Forest, which has provided the Balikpapan oil industry with clean fresh water for their refineries for nearly 60 years, will be presented as a case study. The economic value of the clean water supplied by this forest is quite remarkable with an estimated value is close to $6 million US annually!
