The average height of trees varies from 8.3 to 92 m. , respectively for the facies with A. marina and R. mucronata. 079 45' 29.9'' E), southeast coast of India was selected for pruning experiment. There was no significant difference of the mean measured stem carbon content and the mean predicted stem carbon content from the allometric equations developed for Rhizophora mucronata (Table 5, Student’s t test, ). Generally, mature trees are expected to have long carbon residence time. The present study can be considered as the initial attempt to use a non-destructive method to construct an allometric equation to predict the stem carbon content of Rhizophora mucronata in a tropical conserved mangrove forest. Asiatic Mangrove ( Rhizophora mucronata ) Height: up to 30 m Origin: Southeast Asia Environment: tidal creeks and coastal areas Climate: wet, tropical Notes: The Asiatic Mangrove grows on the banks of tidal creeks, around estuaries and in areas flooded by daily high tides. M. L. G. Soares and Y. Schaeffer-Novelli, “Above-ground biomass of mangrove species. West, “Scaling in biology,” in, B. Lippke, J. Wilson, J. Meil, and A. M. Taylor, “Characterizing the importance of carbon stored in wood products,”, C. A. The residual distribution diagrams for the best model for Rhizophora mucronata is given in Figure 1. The Mean Annual Increment (MAI) of stem diameter and height of R. mucronata and A. marina seedlings is shown on the Table 4. var. For the best fit model, the explanatory variable DBH was statistically significant and the high R2 value of the best fit model indicated that the dependent variable which is the stem carbon content of Rhizophora mucronata can be explained up to high percentage (more than 60%) by the selected explanatory variable, which is DBH. thesis. The basic concept of allometric relationships is that the growth rate of one or more measurements of the tree is proportional to that of other parameters [22]. The tree has a large number of growing to a height of about 20 to 25 metres on the banks of. The total height ranged from 3.5 m to 12.1 m. The merchantable stem height and crown height ranged from 2.3 m to 8.8 m and 0.5 m to 6.9 m respectively. The constructed models, their regression coefficients, and VIFs (variance inflation factors) are given in Table 4. The VIF values were used to measure the effect of multicollinearity among the explanatory variables. On the fringes of the sea 10 or 15 metres (33 or 49 ft) is a more typical height. Sembilan was carried on 21 August 2014 using indirect planting of 1000 Rhizophora mucronata seedlings. The values within the parentheses indicate the range of each parameter. Rhizophora mucronata, a dominant species in the Kenyan mangroves (UNEP, 2001), has been reported on several occasions to form wood which completely lacks growth ... of the tree, but at 130 cm height above ground level. MAI of stem diameter and height of R. mucronata and A. marina seedlings Species Spacing (m) MAI Stem Diameter (mm/yr) Height (cm/yr) Rhizophora mucronata 1 x 1 20,94 a 19,23 a 0,5 x 0,5 20,82 a 15,78 a A diameter tape was used to measure the diameter at breast height (DBH) of each tree, and the clinometer method was used to measure the total tree height, tree crown height, and merchantable stem height. W. M. Dimuthu Nilmini Wijeyaratne, Pawani Madhushani Liyanage, "Allometric Modelling of the Stem Carbon Content of Rhizophora mucronata in a Tropical Mangrove Ecosystem", International Journal of Forestry Research, vol. The descriptive statistics of the tree parameters of, The stem carbon content data are presented as mean ± standard deviation. The mean values of the measured stem carbon content and the predicted stem carbon content using the prediction model for Rhizophora mucronata are given in Table 5. R. R. Twilley, R. Zimmerman, L. Solorzano et al., “The importance of mangroves in sustaining fisheries and controlling water quality in coastal ecosystems,” Tech. Rhizophora mucronata is a small to medium size evergreen tree. However, there was no significant difference in the mean stem carbon content of the trees at the DBH classes 4 and 6. The model was validated using the diagram between the actual values and the residual values and Student’s t test was used to compare the predicted stem carbon content from the allometric equation and the measured stem carbon content. Therefore, it is recommended to extend this allometric equation development method to estimate the stem carbon content of other common tropical mangrove species in order to get an accurate estimate on the contribution of tropical mangrove stem carbon storage capacity for mitigation of global warming. �f�z�bw�yd�R��h�u��'���;3I���Ye��i�j�����~I�-� ��8:Qc�5̏���!�_��n��0�IL��?鉍���V@���>�Ƥ3,�ք����3w��a�#�֯�͎σ�-bMV����(. Accordingly, the two Rhizophora species, Rhizophora apiculata and Rhizophora mucronata, were selected for the study. However, considering the current global warming conditions in the world, it is important to consider the carbon sequestration capacity of the selected species for replantation as the mangrove plants are considered to be excellent carbon dioxide removers from the atmosphere [11, 12]. However, use of destructive methods for this purpose is not advisable as they can disrupt the balance of the carbon removal process. Rhizophora mucronata is a small to medium size evergreen tree growing to a height of about 20 to 25 metres (66 to 82 ft) on the banks of rivers. The method described by Sabin was used to measure the stem volume of each plant [13]. Qualitative assessment of vegetation structure often uses species richness, plant height and apparent zonation of … The residuals values for Rhizophora mucronata were calculated as the difference between the actual stem carbon content and predicted stem carbon content from the model. Rhizophora mucronata species as reported by Fagoonee (1990). The model bias value and the model efficiency values for Rhizophora mucronata were −0.002563323 and 0.7665, respectively. stylosa (Griff.) To construct the model, 75% of data were used. The VIF > 5 suggests that the regression coefficient is poorly estimated due to severe multicollinearity, and 1 < VIF < 5 suggests that regression coefficient is poorly estimated due to severe multicollinearity. This is a very common species in the mangrove forests in the Asian region and found in Cambodia, India, Indonesia, Malaysia Pakistan, Sri Lanka, Thailand, and Vietnam [5, 6]. Seventy individual trees of Rhizophora mucronata were selected from the study area based on purposive sampling. HabitatInhabits the intertidal wetland zone, 0–6 m (0–20 ft) elevation between mean sea level and highest tides, with variable rainfall. We are committed to sharing findings related to COVID-19 as quickly as possible. The tallest trees are closest to the water and shorter trees are further inland.
