Abstract

Repeated forest fires highly impact on tree species composition. Forest planning requires information about the current condition of  species composition. This paper investigates the current tree composition of  natural regeneration after repeated forest fires,  regeneration process after repeated fires, and strategy of  secondary growth related to ecological restoration issues. Re-observation of  the 1.8 hectares permanent plot in Samboja Research Forest was conducted in 2011. All trees with diameters above 10 cm at breast height (DBH) were re-numbered and mapped. Herbarium specimen was collected for species identification. Number of  taxon was determined, Important Value Index was calculated, species trait of   light response was identified based on the references and dispersion index species was calculated. Results show after twenty eight years initial forest fire, 191 species naturally regenerated in the burnt area. Macaranga gigantea, a light demanding pioneer species of  Euphorbiaceae was the most dominant species, followed by Vernonia arborea belonging to Asteraceae. Both, M. gigantea and V. arborea had clumped distribution. Eight species identified survived from repeated fires, are Anthocephalus chinensis, Dipterocarpus cornutus, Diospyros borneensis, Eusideroxylon zwageri, Shorea ovalis, Syzygium borneensis, Pholidocarpus majadum and Vatica umbonata. All surviving species was distributed uniformly in the plot. Dominant pioneer species which has grown after repeated fires indicates that the current condition of  burnt forest is in the early succession. Protecting forest, assisting natural regeneration and monitoring dominant species are suggested as activities for the ecological restoration.

Abstract

Forest and land rehabilitation at kawasan hutan dengan tujuan khusus (KHDTK) Samboja, East Kalimantan had been started in 1988. Many stakeholders were involved in the activities through different mechanisms. However, this program was still far beyond expectation as the success of the rehabilitation program was limited only at the research site of the KHDTK Samboja. Information on potential stakeholders and their roles in the program is needed to formulate a better plan that will be used as a guidance to achieve an effective, efficient and sustainable restoration program in the future. An interview with key informants using snowball sampling method was carried out in BPTKSDA Samboja to identify potential stakeholders that will be involved in the future restoration program, including their interests and possible impacts on the program. The result showed that there was 11 stakeholders that could be engaged in the future Samboja Research Forest Restoration Program; BPTKSDA Samboja, UPTD Tahura Bukit Soeharto, Foresty Officer, Mulawarman University and FOERDIA as key players; Dipterocarp Research Centre and Indonesia Institute of Science as context setter; land manager and forestry industrial companies as subject; non land manager and mining companies as crowd.
