Allometric Relationships for Estimating Stem Volume of Rubber Tree (Hevea Brasiliensis Muell-Arg.) in Bangladesh

Stem volume equation for constructing local volume table of Pinus merkusii Jungh et de Vriese in Tana Toraja community forest

“…According to Maltamo et al (2019) and Saarinen et al (2019), the best model can be identified by its lowest RMSE. The findings of this study corroborate Islam & Ullah (2017) assertion that equation 7 is the optimal model for estimating volume based on tree diameter and height. The equations developed as a result of this research are expected to make a significant contribution to the development of tools for forest inventory implementation.…”

“…According to Liu et al (2019) volume estimation is a very important part of forest management. Estimation of stem volume is necessary for sustainable forest resource planning (Islam & Ullah, 2017). One of the main challenges in forest management is the ability to predict the stem volume of trees accurately and quickly (Soares et al, 2011).…”

“…Stem volume is obtained from modeling in the form of a regression equation which states the relationship between volume and tree diameter and height (Kang et al, 2014;Shrestha et al, 2018). Modeling the volume equation of a tree can be accomplished using linear, exponential, logarithmic, quadratic, or cubic regression equations (Gonzalez-Benecke et al, 2014;Krisnawati, 2016;Islam & Ullah, 2017;Mbangilwa & Jiang, 2019). According to Özçelik & Göçeri (2015), among the various ways to predict tree volume, the modeling method with regression equations is the most accurate approach.…”
