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. Stem up to 400 mm in diameter, straight, with distinctive aerial roots or what is also referred to as knee-roots (breathing roots), with rough reddish, brown to almost … 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]. Rhizophora mucronata is a small to medium size evergreen tree growing to a height of about 20 to 25 metres on the banks of rivers. The stem carbon content can be easily estimated from this model by using an easily measurable tree parameter. B. S. Sabin, “Relationship between allometric variables and biomass in Western Juniper (Juniperus Occidentalis),” Oregon State University, Corvallis, Oregon, 2008, M.S. Qualitative assessment of vegetation structure often uses species richness, plant height and apparent zonation of … Distribution of the residuals for the models indicated a random pattern, and the distribution were between +1 and 1 implying a good fit for linear model (Figure 1). Mangrove ecosystems are identified as important blue carbon ecosystems because they play an important role in carbon sequestration among the coastal ecosystems. 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. 2.2. As it is always better to keep the model simple in the real-world application, the model B was selected as the best model for Rhizophora mucronata. mangrove area of Muara Angke Jakarta using Rhizophora mucronata seedlings with spacings of 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 m. The model bias value and the model efficiency values for Rhizophora mucronata were −0.002563323 and 0.7665, respectively. The stem carbon content of Rhizophora mucronata showed significant positive correlations with DBH (R2 = 0.797, ), total stem height (R2 = 0.648, ≤0.001) and merchantable stem height (R2 = 0.697, ≤0.001) (Table 3). Therefore, the present study was conducted with the objective of using a nondestructive method to estimate the stem carbon content of Rhizophora mucronata in conserved tropical mangrove ecosystems.

In order to find whether the explanatory variables were related to each other, multicollinearity was checked. As trees mature, they sequester less carbon but gain the capacity to store carbon in their stems [28–30]. Red mangrove is a tree with a glossy green, quite compact crown; it can grow 8 - 30 metres tall. Tree allometry is an important tool for estimating tree weight from independent variables such as trunk diameter, tree height, crown height, total height that are easily measurable in the field. The Mean Annual Increment (MAI) of stem diameter and height of R. mucronata and A. marina seedlings is shown on the Table 4. Most of these allometric equations are used for the biomass related studies in terrestrial forest ecosystems. The residual distribution diagrams for the best model for Rhizophora mucronata is given in Figure 1. R. R. Twilley, R. Zimmerman, L. Solorzano et al., “The importance of mangroves in sustaining fisheries and controlling water quality in coastal ecosystems,” Tech. Increment borer was used to collect core samples of tree trunk from each tree at breast height with relatively minor injury to the tree. The method described by Sabin was used to measure the stem volume of each plant [13]. The stepwise regression with backward elimination was used to identify the best fit model to predict the stem carbon content of Rhizophora mucronata. Therefore, total height, stem height, and crown height were eliminated to refit the model. Rhizophora apiculata is a species of plant in the Rhizophoraceae family. %PDF-1.6 %���� To construct the model, 75% of data were used. Growth rate of R. mucronata showed variations on absolute daily height growth rate range of 0.215-3.333 mm/day (average 1.296 0.036 mm/day), while absolute daily diameter growth rate range was 2.15x10-3-0.196 mm/day (average 4.25x10-2 3.59x10-2 mm/day). Carbon sequestration performance at each diameter class was determined by calculating the mean stem carbon content at each diameter class. The results of the correlation analysis are given in Table 3. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The highest percentage increase of mean stem carbon content was observed between the DBH classes 1 and 2. Declining tree growth over time is caused due to changes in the supply rate of required resources (light, nutrients, and water), change in balance between photosynthesis and respiration, increased hydraulic resistance, decreased nutrient supply, or genetic changes with meristem age which can result in increased carbon storage capacity of the mature trees compared to the new trees [17–21]. Accordingly, the two Rhizophora species, Rhizophora apiculata and Rhizophora mucronata, were selected for the study. Rhizophora mucronata is a slow-growing, much-branched, evergreen tree growing up to 27 metres tall, with a bole 50 - 70 cm in diameter Rhizophora mucronata is a small to medium size evergreen tree. We therefore selected three species of mangroves with different propagule size: Avicennia marina (2.5 ± 0.3 cm), Bruguiera gymnorrhiza (16 ± 2 cm) and Rhizophora mucronata (36 ± 3 cm). 9 cm. Under these conditions Rhizophora stylosa is able to reach a height of up to 30 meters but usually stops height between 5 to 20 meters. 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. Stepwise regression with backward elimination was used to identify the major predictors of stem carbon content of Rhizophora mucronata. Classification. 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. Previous studies conducted in this part of the country to assess the mangrove carbon sequestration capacity have used destructive methods [31, 32]. However, use of destructive methods for this purpose is not advisable as they can disrupt the balance of the carbon removal process. In the model A, total height (VIF = 22.20), stem height (VIF = 10.22), and crown height (VIF = 9.75) indicate high multicollinearity. However, the carbon sequestration potential of Rhizophora mucronata is not widely researched in the tropical mangrove ecosystems. Sembilan was carried on 21 August 2014 using indirect planting of 1000 Rhizophora mucronata seedlings. 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]. Height distribution analysis showed that eighty-eight percent (88%) of the mangroves were 8.5m high and mostly consisted A. marina, R. apiculata and R. mucronata.Very few tall trees (16m above high) were encountered and this comprised only 1% of the total population. Click on a scientific name below to expand it in the PLANTS Classification Report. The constructed models, their regression coefficients, and VIFs (variance inflation factors) are given in Table 4.

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. 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. Model fit was examined using value, R2 value, and residual diagram. The black mangrove, usually of moderate height, sometimes grows 18 to 21 metres (59 to 69 feet) tall. However, there is no consensus on the contribution of old trees to carbon storage due to lack of long-term individual tree data [16]. Rhizophora mucronata belongs to family Rhizophoraceae. The present study was conducted to develop an allometric model to determine the stem carbon content of Rhizophora mucronata in a conserved tropical mangrove ecosystem. M. L. G. Soares and Y. Schaeffer-Novelli, “Above-ground biomass of mangrove species. The descriptive statistics of the tree parameters of, The stem carbon content data are presented as mean ± standard deviation. This study was conducted in a major mangrove conservation forest, The Kadol Kale mangrove forest located in Sri Lanka. Under these conditions Rhizophora mangle is able to reach a height of up to 35 meters but usually stops between 10 to 20 meters. The tree has a large number of aerial stilt roots buttressing the trunk. The height and growth of the Red Mangrove is in direct relation with the location where it grows and the existing growth conditions. The variations of stem carbon content at different DBH classes are given in Table 2. Table 4. Rhizophora mucronata has a developed strong root system, which can hold the sediments tightly, and thereby, they can serve as very important coastline stabilizers to protect the coastal ecosystems from strong storms, waves, and coastal erosion. 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. There has been no specific study to highlight why R. mucronata became the dominant species of the Therefore, it is very important to measure the carbon content of the tree stems, in order to estimate the role of a particular tree species in removal of excessive carbon dioxide from the atmosphere. The most common tropical mangrove genera include Avicennia, Rhizophora, Bruguiera, and Sonneratia. The residual diagram of residual versus actual values for Rhizophora mucronata is given in Figure 2.

The significantly highest stem carbon content was recorded from the Rhizophora mucronata trees at DBH class 5 (12.1 cm–14.00 cm). On the fringes of the sea 10 or 15 metres is a more typical height. The structure of mangrove vegetation is characterized in terms of species richness, diversity, tree/stem density, species and stand basal area, frequency of occurrence of constituent species, plant/stand height, above ground biomass and canopy volume/leaf area index. SizeCan reach 30–40 m (100–130 ft) in height, although commonly reaches 5–8 m (16–26 ft). Rep., U.S. Agency for International Development, Program in Science and Technology Cooperation, Washington, DC, USA, 1990, Interim Report. Seventy individual trees of Rhizophora mucronata were selected from the study area based on purposive sampling. The plant height was 8 % higher in Rhizophora mucronata than that in Avicennia marina. The tree often branches from low down, and can have more than one bole, which can be 25 - 60cm in diameter [. The model bias values and the model efficiency values for the best fit model suggested that the model is suitable to be used practically. In addition, Rhizophora mucronata is commonly used in the tropical mangrove replantation programmes due to its adaptability and rapid growth rate. Mangroves play an important role in carbon sequestration in tropical and subtropical coastal areas, and they have a considerable contribution of carbon dioxide mitigation. stylosa (Griff.) 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 data are presented as mean ± standard deviation. Two times of assessments, 17 May and 19 August 2015 were done to monitor and evaluate 325 ten months-rehabilitated seedlings. B.

The mangrove species (Rhizophora mucronata Poir.) However, few studies have used tree allometric modelling to determine the above ground biomass of mangrove trees in some regions of the world [22–27]. Furthermore, the results of the present study identifies that the Rhizophora mucronata as a suitable species to be used in mangrove replantation programs as it has the maximum carbon storage capacity when the trees are at a DBH range of 12–14 cm. They have elongated tips but these often brea… Damaged trees and trees devoid of leaves were not sampled during the study to avoid the effects on biomass accumulation process. Data on Plot C measurement results of the Rhizopora mucronata Rehabilitation Forest Dimension. Only 75% of data were used in construction of the model while other 25% of data were used in model validation. Review articles are excluded from this waiver policy. The correlation between the stem carbon content and the individual tree parameters was assessed using person’s correlation analysis. The average height of trees varies from 8.3 to 92 m. , respectively for the facies with A. marina and R. mucronata. In Rhizophora mucronata, the bacterial treatment increased the shoot height growth at different levels of salinity. 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. The transformed data were used in model construction, evaluation, and validation. The percentage increase of mean stem carbon content compared to previous diameter class was also calculated.

The data were tested for normality using the Anderson Darling test, and the nonnormalized data were log transformed as appropriate. The actively growing trees can store more carbon in their stem. Leaf area was not statistically significant. It ranged from 0.41 to 8.75 m respectively in 1 year and 16.3 year old plantations (Table 1). HabitatInhabits the intertidal wetland zone, 0–6 m (0–20 ft) elevation between mean sea level and highest tides, with variable rainfall. 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. The mangrove forests are very diverse ecosystems and they consist of true mangroves, mangrove-associated plants, and other organisms [1]. 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. The result showed there were changes on environment parameters. For Rhizophora mucronata DBH, crown height, total height, and stem height () were statistically significant with stem carbon content. x�bbd```b``Y"_�� The approximate global area covered by mangrove forests is estimated to be 140,000 km2 with the highest extent of mangroves occurring in Asia (42%), followed by Africa (20%) and North and Central America (15%) [2]. The values within parentheses indicate the range of variation of the measured and predicted stem carbon content. The VIF = 1 means that there is no multicollinearity among the explanatory variables, and therefore, these variables are best suited to fit into the model. The present study identifies that the allometric model, Ln C = −2.403 + 2.247 Ln DBH as the best fit and practical model to estimate the stem carbon content of Rhizophora mucronata. The model bias and modelling efficiency values for the best fitted model of Rhizophora mucronata was used for the evaluation of the model. 079 45' 29.9'' E), southeast coast of India was selected for pruning experiment. On the fringes of the sea 10 or 15 metres (33 or 49 ft) is a more typical height. Rhizophora mucronata species as reported by Fagoonee (1990). The best fitted model was evaluated using quantitative and qualitative evaluation methods as described by Subasinghe and Haripriya [15]. The measured stem carbon content of the Rhizophora mucronata trees used for model validation ranged from 1.3 kg to 4.3 kg and their predicted values ranged from 1.3 kg to 3.6 kg. The leaves are 5 to 7.5 cm (2 to 3 inches) long, opposite, oblong or spear-shaped; the upper surface is green and glossy, the lower surface whitish or grayish. from demarcated plots of using plot-less methods. Coastal ecosystems such as mangrove forests are identified as blue carbon ecosystems and they store more carbon per unit area than terrestrial forests and therefore are recognized as highly important ecosystems to mitigate climate change [12]. growing to a height of about 20 to 25 metres on the banks of. The value of the best fit model for Rhizophora mucronata was statistically significant as it was lower than the alpha level of 0.01 (Table 4, stepwise regression analysis with backward elimination method). Rhizophora mucronata Lam. 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, ). Findings of the present study can be extended to estimate the functional capacities carbon sequestration by other Sri Lankan mangroves, and therefore encourage rational decision making on conservation and management of mangrove areas for their ecological services including their carbon sequestration capacity and influence to mitigate predicted climatic changes. The reserved 25% of data were used for model validation. Generally, mature trees are expected to have long carbon residence time. The present study used a nondestructive method of measuring individual tree parameters to develop this allometric equation to predict the stem carbon content and it is considered as an environmentally friendly approach with minimum damage to the tree. The stem carbon content of the sampled trees ranged from 3.5 … Their average diameter is 14 cm (with a minimum of 6.37 cm and a maximum of 23.57 cm) for the first and 15 cm (with The fixed stem carbon biomass of all the core samples was determined by loss on the ignition method as described by Guendehou and Leehtonen [14]. The studies that have been conducted so far have followed a destructive method of sampling, which involves the removal of sampled trees from the ecosystem and measuring the carbon content stored in the plant parts. phoraceae), Rhizophora mucronata, Bruguiera gymnorhiza, and Sonneratia alba. The total leaf area of the sampled trees ranged from 1.7 m2 to 50.5 m2. 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. ... as well as Rhizophora mucronata, ... Island in Western Visayas, while 12 were discovered in Masinloc, and they have an average diameter of 5.5 centimeters and height of 6 meters.
