Sreekumar 3 Division of Soil Science, Kerala Forest Research Institute, Peechi 680 653, Kerala, India > Research Paper 2020 1 12 2020 10 22 The diameter at breast height in relation to the height (Dbh:H) in mangroves may differ with respect to the region and regions generating large-volume assessments of biomass in the above-ground results in fallacy if these differences in species are neglected. A performance assessment with 11 existing non-linear and linear models were held to pick the optimum solution that resolves the Dbh-h relation in mangroves lying in proximity to the Western coastal line of India using a dataset of heights and Dbh of 1034 trees. To assess the chosen models, we adopt AIC system. As per the inference, monomolecular model with a value of 4933.43 (AIC) was bet fit for pooled data.
