However, use of destructive methods for this purpose is not advisable as they can disrupt the balance of the carbon removal process. The model bias values and the model efficiency values for the best fit model suggested that the model is suitable to be used practically. The percentage increase of mean stem carbon content decreased in the other successive DBH classes (Table 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. Determination of the stem carbon content of individual species is very important and can play a key role when assessing the carbon sequestration capacity of the ecosystems. I. analysis of models,”, J. H. Brown and G. B. The total leaf area of the sampled trees ranged from 1.7 m2 to 50.5 m2. The actively growing trees can store more carbon in their stem.

The tree has a large number of aerial stilt roots buttressing the trunk. 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 Archimedes displacement principle was used to measure the initial volume of the collected core samples. Figures 4–5 show the height and dbh distributions of mangrove species in meters and centimeters respectively. The mean stem carbon content at the lowest diameter class was significantly lower than the other diameter classes. The stepwise regression with backward elimination was used to identify the best fit model to predict the stem carbon content of Rhizophora mucronata. The average height of trees varies from 8.3 to 92 m. , respectively for the facies with A. marina and R. mucronata. Seventy individual trees of Rhizophora mucronata were selected from the study area based on purposive sampling. Two times of assessments, 17 May and 19 August 2015 were done to monitor and evaluate 325 ten months-rehabilitated seedlings. The data were tested for normality using the Anderson Darling test, and the nonnormalized data were log transformed as appropriate. The most common tropical mangrove genera include Avicennia, Rhizophora, Bruguiera, and Sonneratia.

SizeCan reach 30–40 m (100–130 ft) in height, although commonly reaches 5–8 m (16–26 ft). 079 45' 29.9'' E), southeast coast of India was selected for pruning experiment. The authors declare that there are no conflicts of interest regarding the publication of this article. The Mean Annual Increment (MAI) of stem diameter and height of R. mucronata and A. marina seedlings is shown on the Table 4. Damaged trees and trees devoid of leaves were not sampled during the study to avoid the effects on biomass accumulation process. These genera are identified as most suitable species to be used in tropical mangrove replantation programmes due to their ability to distribute in a wide range of soil and hydrological conditions [3]. 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). The highest percentage increase of mean stem carbon content was observed between the DBH classes 1 and 2. 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 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. 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. 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. var. This effect was higher by 44.2% in the bacillus-treated seedlings grown under 35 g l-1 salinity (Figure 1), by 39.6% in the mixture treated seedlings raised under 17.5 g l-1, and by 28.1% in the azotobacter-treated West, “Scaling in biology,” in, B.

Click on a scientific name below to expand it in the PLANTS Classification Report. This is a non-destructive method and it is environmentally friendly as it does not require the tree to be removed from its natural environment. Sign up here as a reviewer to help fast-track new submissions. The constructed models, their regression coefficients, and VIFs (variance inflation factors) are given in Table 4. The predictor variables used were DBH (diameter at breast height), total height, crown height, merchantable stem height, and leaf area. 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]. apiculata used in the present study had 3-4 months of age with an average height of 46±2 cm with 3-4 leaves obtained from Surabaya City Agriculture Office nursery around the mangrove forest in Wonorejo. 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 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 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]. Increment borer was used to collect core samples of tree trunk from each tree at breast height with relatively minor injury to the tree. 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. Carbon sequestration performance at each diameter class was determined by calculating the mean stem carbon content at each diameter class. The residual diagram showed a random pattern indicating that the model can be proved to use in the real world (Figure 2). ImageJ software was used to measure the leaf area of each tree (https://imagej.nih.gov/ij/). Rhizophora mucronata Lam. 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. 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. B. S. Sabin, “Relationship between allometric variables and biomass in Western Juniper (Juniperus Occidentalis),” Oregon State University, Corvallis, Oregon, 2008, M.S. Sembilan was carried on 21 August 2014 using indirect planting of 1000 Rhizophora mucronata seedlings. Rhizophora mucronata is a slow-growing, much-branched, evergreen tree growing up to 27 metres tall, with a bole 50 - 70 cm in diameter 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. 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]. 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 Lam. 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. This study was conducted in a major mangrove conservation forest, The Kadol Kale mangrove forest located in Sri Lanka. The height and growth of the Red Mangrove is in direct relation with the location where it grows and the existing growth conditions. The tree often branches from low down, and can have more than one bole, which can be 25 - 60cm in diameter [. The descriptive statistics of the tree parameters of, The stem carbon content data are presented as mean ± standard deviation. Red mangrove is a tree with a glossy green, quite compact crown; it can grow 8 - 30 metres tall. The model bias value and the model efficiency values for Rhizophora mucronata were −0.002563323 and 0.7665, respectively. 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. In Rhizophora mucronata, the bacterial treatment increased the shoot height growth at different levels of salinity. The residual distribution diagrams for the best model for Rhizophora mucronata is given in Figure 1. The stem carbon content can be easily estimated from this model by using an easily measurable tree parameter. The transformed data were used in model construction, evaluation, and validation. 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]. VegetationMangrove communities. The plant height was 8 % higher in Rhizophora mucronata than that in Avicennia marina. 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, ). 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]. Two models (Model A and Model B) were constructed from the stepwise regression with backward elimination method: Model A: Ln C = −1.545–2.122 Ln TH + 2.020 Ln MSH + 0.874 Ln CH + 2.011 Ln DBH Model B: Ln C = −2.403 + 2.247 Ln DBHHere, C: stem carbon content, TH: total height, MSH: merchantable stem height, CH: crown height, and DBH: diameter at breast height.

The black mangrove, usually of moderate height, sometimes grows 18 to 21 metres (59 to 69 feet) tall. 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. On the fringes of the sea 10 or 15 metres is a more typical height. 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. The result showed there were changes on environment parameters. 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]. Description A small to medium-sized tree, 2–5 m, even up to 10 m tall, with strong apical dominance. The data are presented as mean ± standard deviation. 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.

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. 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]. 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. Rhizophora mucronata belongs to family Rhizophoraceae. 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). �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����(. In the model A, total height (VIF = 22.20), stem height (VIF = 10.22), and crown height (VIF = 9.75) indicate high multicollinearity. Most mangrove forests are located in tropical areas, although there are some expansions into subtropical regions as well. Rhizophora mucronata species as reported by Fagoonee (1990). Rhizophora apiculata is a species of plant in the Rhizophoraceae family. The reliability of the model was 76.7%, and the model was significant at 95% level of significance. 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. 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 total leaf area of the sampled trees ranged from 1.7 m 2 to 50.5 m 2.

According to Kathiresan and Rajendran (2005), Rhizophora mucronata and Bruguiera gymnorrhiza are cosmopolitan species with wide distribution in Indian Ocean. Only 75% of data were used in construction of the model while other 25% of data were used in model validation. However, there was no significant difference in the mean stem carbon content of the trees at the DBH classes 4 and 6. The correlation between the stem carbon content and the individual tree parameters was assessed using person’s correlation analysis. Accordingly, the two Rhizophora species, Rhizophora apiculata and Rhizophora mucronata, were selected for the study. 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. Propagules, those about to detach from trees were collected in August, 2013 in Pambala lagoon, Sri Lanka (7°34’N, 79°48’E) to use in the experiment.
