Estimation of root biomass based on excavation of individual root systems in a primary dipterocarp forest in Pasoh Forest Reserve, Peninsular Malaysia

Abstract: Abstract:Precise estimation of root biomass is important for understanding carbon stocks and dynamics in tropical rain forests. However, limited information is available on individual root masses, especially large trees. We excavated 121 root systems of various species (78) and sizes (up to 116 cm in dbh), and estimated both above- and below-ground biomass in a lowland primary dipterocarp forest in the Pasoh Forest Reserve, Peninsular Malaysia. A tree census was conducted in four research plots (each 0.2 ha) a… Show more

“…primary production, carbon storage, soil conservation, and nutrient cycling (Giardina and Ryan 2002;Grünzweig et al 2007;Litton and Giardina 2008;Liao et al 2010). However, most of the ecosystem services associated with forest root systems are largely unexplored due to the difficulty in estimating belowground biomass at large scale (Le Goff and Ottorini 2001;Peri et al 2006;Niiyama et al 2010;Yuen et al 2013). Traditionally, destructive methods such as whole or partial root system excavation have been used to investigate belowground biomass in forest ecosystems.…”

“…Estimating belowground biomass is therefore a complex process which requires much effort in terms of time and cost for collecting data (Niiyama et al 2010;Ruiz-Peinado et al 2013;Marziliano et al 2014). Although the research conducted on this topic is extensive, quantitative knowledge on belowground biomass distribution in forest ecosystems still remains scarce (Cairns et al 1997;Brunner and Godbold 2007;Litton et al 2007).…”

“…We adopted β=0.43 y -1 and ID= 0.7×(dbh/2) 0.2 ÷1.75 for CWD, and the initial necromass of CWD=23.6 t C ha -1 , which provided optimum results for CWBBM at Plot 1 in Pasoh FR (Yoneda et al 2016). The initial weight of coarse woody organs including roots of a dead tree was estimated by the allome tric regressions obtained in this forest reserve (Kato et al 1978, Niiyama et al 2010. Ten trials were conducted to assess yearly changes in the following dimensional parameters for coarse woody organs with 10 dbh-database simulations from 10 trials on dead trees: biomass (BM c ), necromass of CWD (CWD), NPP c , annual death rates (DR c ) and HTR c for total coarse woody organs, including roots.…”
