As a result of unsustainable management and wild fires, Indonesia is covered by over 20 million hectares of degraded forests. These heavily disturbed forests need to be rehabilitated. The International MOFEC (Indonesian Ministry of Forestry and Estate Crops)-Tropenbos Kalimantan Project recognized this problem and started a Dipterocarpaceae research programme in 1987, focusing on mycorrhizas, vegetative propagation and planting stock production, selection of species, soil and site classification, growth and yield studies and economics. This paper briefly discusses the different research efforts related to the production of planting stock, the rehabilitation of Imperata cylindrica grasslands and enrichment plantings in secondary forest. The research setting is described by giving some details of forest history, the characteristics of the area and the impact of fires. The fires of 1997-98 essentially destroyed all field experiments. Results of experiments and observations with Dipterocarp species in enrichment line plantings in the Wanariset Research Forest (East Kalimantan) during the years 1989-99 are summarized. Species choices, planting stock production, planting establishment and maintenance are discussed. First year results of the establishment of 170 ha of line plantings in burnt secondary forest are presented. On the basis of these results, future research is proposed and suggestions are made on how to proceed.
