“…Allometry is a powerful tool for estimating biomass production from easily measured tree characteristic such as stem diameter and height that are quantifiable in the field (Komiyama et al, 2005). Common allometric equations have been reported for aboveground biomass (Brown et al, 1989;Brown, 1997;Ketterings et al, 2001) and also for mangroves biomass (Komiyama et al, 2002;Ong et al, 2004;Nguyen and Ninomiya, 2007) elsewhere.…”

Problem statement: Mangrove forests are found in tropical and subtropical coastal tidal regions. Rhizophora apiculata Blume is one of the most important species in mangrove forest. It is also one of the commercial mangrove timber species in Asia-Pacific region which dominates large areas of mangrove in this region. In order to understand forest ecosystem characteristics and to establish the proper management system, a precise estimation of biomass is necessary. The objective of this study is to quantify the aboveground biomass production and stem volume of R. apiculata in Awat-Awat mangrove forest, Sarawak. Approach: Seven representative trees were used in this study for sampling from February 2011 to March 2011. Allometric relationships were examined using either independent variable Diameter (D) or combination of quadratic of D and Height (D 2 H). Results: The best fit of allometric equations were developed from the combination of quadratic of D and H (y = 0.055×0.948, R 2 = 0.98) which is more recommended to estimate biomass and stem volume of R. apiculata in Awat-Awat mangrove forest, Sarawak. Total aboveground biomass and stem volume of R. apiculata were 116.79 t h −1 and 65.55 m 3 h −1 , respectively. Conclusion: Aboveground biomass and stem volume is closely related with tree diameter and height which indicates that aboveground biomass and stem volume will increase with increasing diameter and height of R. apiculata.

“…The site-independency of the Ws-DBHH relationship proved that this difference in specific gravity was ignorably small for attaining a site-dependence in allometric relationship for stem weight. Recently, the allometric relationships using the specific gravity of stem as a part of the variable have been proposed by some authors for establishing species-and site-specific allometric relationships (Brown et ai., 1989;Ketterings et at., 2001;Komiyama et at., 2002).…”

Site-independent allometric relationships for above-ground weight were studied for three groups of mangroves: Rhizophora, Bruguiera, and other species. A hundred and one tree samples were collected from five forest sites where a major difference is geographical locality. For stem weight, a site-independent allometric relationship using the variable DBH'H or DROiH (D"", = stem diameter at 30 cm above the highest prop root) was attained for each group, because the specific gravity of wood and overall stem shape are identical among the trees of the different sites. Although some mangroves showed difference in specific gravity of wood among different sites, this difference was not large enough to effect the site segregation of the allometric relationship for stem weight. The allometric relationships for the branch and leaf weights of all studied mangroves differed by site when we used DBH'H or DROiH as an independent variable. However, when we used the stem diameter at the height of the lowest branch DB as an independent variable, the difference in allometric relationships for both branch and leaf weights among sites became smaller. We discussed the application of the Pipe Model (Shinozaki et ai. 1964) for establishing site-independent allometric relationships common to a variety of geographically distinct mangroves.

This research assesses the effects of different patterns of cocoa farming at the margin areas of Lore Lindu National Park (LLNP) forest by estimating species richness, density of vegetation, biomass potential, litter production, litter decomposition rates and farming income. Research was conducted in the LLNP, Central Sulawesi, Indonesia. Five patterns of cocoa farming systems were considered: cocoa farming + mixed wood trees (agroforestry complex), cocoa farming + fruit trees (agroforestry simple), cocoa farming + candlenut trees (agroforestry simple), cocoa farming + teak trees (agroforestry simple), and monoculture cocoa farming. Five sample plots were made in each cocoa-farming pattern, sized 20 x 20 m for tree vegetation sampling. Subplots of 10 x 10 m, 5 x 5 m, and 2 x 2 m were used to sample vegetation at earlier growth stages. The results showed that using a pattern of cocoa + mixed wood trees (agroforestry complex) produced the highest biomass. A pattern of cocoa + candlenut gave the highest average income per year, but the pattern of cocoa + mixed wood trees did differ significantly from that using candlenut. It is suggested that cocoa farming with mixed wood trees (agroforestry complex) along the perimeter of the LLNP forest will support the sustainability in biodiversity, water catchment areas and disaster control.
