Rain forests in Central Kalimantan, Borneo, are under increasing pressure from commercial industry, agricultural projects and transmigration programmes. Our knowledge of the hill forests in central Borneo is virtually non-existent, yet they may disappear before we realize their true value as intact forests. These rapid developments prompted the FFPS to launch the Red Alert Project, which, together with Project Barito Ulu, is investigating ways to promote rain-forest conservation in Kalimantan, Indonesia. © 1991, Fauna and Flora International.
