“…In present study, R. apiculata shows comparatively higher aboveground biomass than mixed mangroves (R. apiculata, R. mucronata, B. gymnorrhiza, B. parviflora, C. tagal, Xylocarpus granatum) in Langkawi Island, Malaysia (Norhayati and Latiff, 2001), C. tagal in Satun, Thailand (Komiyama et al, 2000) and K. obovata in Okinawa, Japan (Khan et al, 2009). Moreover, the biomass value of R. apiculata was comparable with the values recorded elsewhere Table 2.…”

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.

Carbon and Nitrogen Stocks and Below-Ground Allometry in Temperate Mangroves

Mangroves play an important role in the storage of carbon (C) and nitrogen (N) within estuarine systems, yet are being lost at an alarming rate throughout the tropics. In contrast, temperate mangroves have increased in area at many locations in recent decades. Field surveys, sediment sampling, allometry, and C and N analysis were used to determine total C and N stocks in five temperate Avicennia marina subsp. australasica forests in New Zealand. This is the first study developing allometric functions to estimate root biomass C and N stocks for A. marina. A. marina forests stored 117.1 ± 16.8 t C ha −1 and 15.4 ± 1.0 t N ha −1 in above and below-ground biomass and sediment to 100 cm depth. Below-ground biomass and sediment C and N stocks contributed 88 ± 3 and 99 ± 0.4% to total C and N stocks, respectively, emphasizing the importance of below-ground biomass and sediment in mangrove ecosystems. The results of this study can be used to inform management decisions for estuarine and coastal ecosystems, currently undergoing rapid changes in mangrove area.

“…In the temperate forest, T/R ratio ranges from 2. 68-3.70 (Yamada and Shidei, 1972;Komiyama et al, 2000). However, the T/R ratio of K. ivorensis stand was 3.47 higher than that in H. odorata stand (1.78).…”

“…The result our study are similar to those reported by Kamo et al (2008) where the T/R ratio of exotic species (Acacia species) was higher (5.2-6.1) compared with slow growing of indigenous species (Pterocarpus macrocarpus and Xylia xylocarpa) which were T/R ratio 2.8-2.9, respectively. The low T/R ratio indicates that the amount of tree biomass was accumulated at belowground root biomass, as studied by Komiyama et al, (2000) on Ceriops tagal that have a T/R ratio of 1.05, where the root biomass was higher than that aboveground biomass. This indicates that the estimate of root accumulation of the tree species is needed to understand the overall carbon stock process in the tropical forest areas.…”

Problem statement:There is general agreement that human activities such as deforestation and land use change to other land use types have contributed to degraded secondary forests or forestland and increases the emission of greenhouse gases which ultimately led to global climate change. An establishment of forest plantation in particular is regarded as an important approach for sequestering carbon. However, limited information exists on productivity and potential of fast growth exotic and indigenous tree plantations for sequestering CO 2 from the atmosphere through photosynthesis. This study aimed at assessing the productivity and biomass accumulation along with the potential for sequestering CO 2 of planted exotic and indigenous species on degraded forestland. Approach: This study was conducted at Khaya ivorensis and Hopea odorata plantations, which was planted at the Forest Research Institute Malaysia (FRIM) Research Station in Sega mat Johor, Malaysia five years ago. In order, to evaluate the forest productivity and biomass accumulation of both species, we established plots with a size of 40x30 m in three replications in each stand, followed by measuring all trees in the plots in terms of height and Diameter at Breast Height (DBH). To develop allometric equation, five representative trees at each stand were chosen for destructive sampling. Results: The growth performance in terms of mean height, DBH, annual increment of height and diameter and basal area of exotic species (K. ivorensis) was significantly higher than that of the indigenous species (H. odorata). We used the diameter alone as independent variable to estimate stem volume and biomass production of both species. The stem volume of K. ivorensis stand was 43.13 m 3 ha −1 and was significantly higher than H. odorata stands (33.66 m 3 ha −1 ).The results also showed that the K. ivorensis and H. odorata stands have the potential to absorb CO 2 from the atmosphere which was stored in aboveground biomass with value 15.90 Mg C ha −1 and 13.62 Mg C ha -1 , respectively. In addition, the carbon content in root biomass of H. odorata stand was higher than that in K. ivorensis stand with value 7.67 Mg C haand 4.58 Mg C ha −1 , respectively. Conclusion/Recommendation:The exotic (K. ivorensis) and indigenous (H. odorata) species which was planted on degraded forestland exhibited different growth rate, biomass production and ability to absorb CO 2 from the atmosphere in each part of the tree. In general, forest productivity and ability to absorb CO 2 from the atmosphere of exotics species (K. ivorensis) was higher than that indigenous species (H. odorata). These findings suggest that forest plantation productivity has been affected by species characteristics and suitability of species to site condition. Thus, to sustain high productivity with suitable species selection for carbon sequestration, these factors should be considered for future forest establishment.
