Samenvatting

This report is part of a collaborated study initiated by the SEnSOR programme to assess each of the compartments of aboveground carbon (AGC) stocks in fragmented lowland dipterocarp forests in Sabah. The biomass and carbon contents of living trees and coarse woody debris, lianas, fine woody debris (FWD) and litter, were studied and reported in three parts. The litter and FWD carbon stocks elaborated in this report are important components of AGC because they are an indicator of the health of the forest and form the link between key ecosystem processes, such as litterfall and decomposition. Litter is defined as all dead biomass on the forest floor with a diameter smaller than 1 cm, fine woody debris includes all dead biomass with a diameter between 1 and 10 cm. We collected samples and data of each forest component in twelve forest fragments ranging in size from 12 to 3529 hectares and two continuous forest sites, during June and July 2016.
