Tropical forests are being cleared at a rate of 16.9 million hectares per year and timber harvesting results in over 5 million hectares becoming secondary forests annually without adequate management. This decrease and degradation affect both timber production and many environmental values. Selec...

Site management strategy on the forest harvesting and short/long-term rotation of plantation
From a study conducted in Pasoh Forest Reserve, 149 tree species in 92 genera and 38 families, all trees with a diameter breast height (dbh) of 1 cm or above were enumerated in a one hectare plot. The most abundant species was Ficus fistulosa across all dbh classes followed by Monocarpia marginal...

Effects of soil properties on growth of young tree seedlings of Hopea odorata and Azadirachta excelsa in line and gap enrichment planting in logged-over tropical lowland forest were evaluated. At 13 months, the trees were grouped into “good” and “poor” growth based on their height increment in th...
Soil samples from permanent sample plots of natural mixed deciduous, logged-over mixed deciduous and the secondary stands in the tropical seasonal forest were analysed for physical and chemical properties. Bulk density and soil hardness of A-horizon in the natural stand were slightly higher than ...

In the Guarani preservation area 100 ha of forest land was cut to evaluate harvest impact in natural subtropical forest. Two treatments were applied: “commercial logging” in which the logging contractor works in the traditional way, and “improved harvest” in which trees are selected and the skidd...

Four rehabilitation methods were tested in logged-over lowland tropical forest in Pasoh Forest Reserve, Negeri Sembilan, Peninsular Malaysia. The treatments were: line planting (T1), gap planting 10m x 10m x 5 ha-1 (T2), gap planting 20 m x 20 m x 5 ha-1 (T3) and gap planting 10 m x 10 m x 9 ha-1...
