Heath forests which are tropical forests on sandy soils are widely distributed in Borneo and provide many ecosystem services, such as carbon storage and non-timber forest products. Over the past several decades, such forests have been disturbed by no

Although an estimation of forest biomass is essential for the development of a carbon storage baseline in the ''Reducing Emissions from Deforestation and Deg- radation in Developing Countries'' scheme, few have been conducted in logged-over rain fore

Soil compaction is major determinant of plant growth and/or mortality. Tropical rainforests in Southeast Asia have been degraded by commercial logging, and the use of heavy equipment in these operations has increased soil compaction. We conducted enr

Enrichment planting with climax trees such as dipterocarps is required to rehabilitate degraded tropical forests in Southeast Asia, because these forests have been damaged by various anthropogenic activities. Severely degraded tropical secondary fore

Uncertainties in the rate of biomass variation with forest ageing in tropical secondary forests, particularly in belowground components, limit the accuracy of carbon pool estimates in tropical regions. We monitored changes in above- and belowground b

Although allometric equations can be used to accurately estimate biomass and/or carbon stock in forest ecosystems, few have been developed for logged-over tropical rainforests in Southeast Asia. We developed allometric relationships between tree size
