Planting indigenous tree species to rehabilitate degraded forest lands: the Bintulu project Malaysia

Yusuf Hadi, . and Abas Said, . (1992) Planting indigenous tree species to rehabilitate degraded forest lands: the Bintulu project Malaysia. [Proceedings Paper]

This paper describes the initial results of a joint research project between Universiti Pertanian Malaysia and Yokohama National University entitled Rehabilitation of Tropical Rainforest Ecosystems conducted on a 50-ha site in the Bintulu campus of Universiti Pertanian Malaysia. The four-year project funded by Mitsubishi Corporation is conducted in four phases beginning 1990 involving 3 4 3 7 7 0 and 33.4 ha respectively. The project objective is to develop techniques to rehabilitate degraded forest lands by planting indigenous fores tree species. A total of 127 872 seedlings have been produced from seeds and wildings collected from the surrounding forests. The major species of seedlings produced are Shorea ovata S. mecistopteryx S. lepsosula Hopea kerangasensis Hopea beccariana Eugenia sp. and Calophyllum sp. Some 42 232 seedlings have been planted in the first phase and 11 971 in the second phase. Different site preparation and planting methods are employed depending on the condition of the sites. Method A employed in severely eroded and compacted areas involves removal of existing vegetation construction of wooden lattices to minimize soil erosion ploughing and soil mulching. In such areas three seedlings are planted per square meter. Method B used in grassland and shrub areas with less severe soil erosion and compaction consists of removing one-meter strips of vegetation and retaining half-meter in between to provide shade to planted seedlings which are spaced one meter apart. Method C involves retaining the canopy of the existing secondary forest species to provide shade and removal of the undergrowth to minimize competition. Seedlings are planted 3 m by 3 m. The survival of planted seedlings in the first year has been encouraging averaging 70.1 89.2 and 94.4 per cent under Methods A B and C respectively. Several problems have been encountered and additional studies are being planned.

Abstract

This paper describes the initial results of a joint research project between Universiti Pertanian Malaysia and Yokohama National University entitled Rehabilitation of Tropical Rainforest Ecosystems conducted on a 50-ha site in the Bintulu campus of Universiti Pertanian Malaysia. The four-year project funded by Mitsubishi Corporation is conducted in four phases beginning 1990 involving 3 4 3 7 7 0 and 33.4 ha respectively. The project objective is to develop techniques to rehabilitate degraded forest lands by planting indigenous fores tree species. A total of 127 872 seedlings have been produced from seeds and wildings collected from the surrounding forests. The major species of seedlings produced are Shorea ovata S. mecistopteryx S. lepsosula Hopea kerangasensis Hopea beccariana Eugenia sp. and Calophyllum sp.
