Dataset on diameter at breast height, tree height and volume measurements of Toona ciliata

This dataset contains quantitative measurements of growth and yield parameters of Toona ciliata, an important timber species widely cultivated in tropical and subtropical regions. The dataset is designed to support forestry research, biomass estimation, and growth modeling studies.The dataset includes three primary variables:Diameter at Breast Height (DBH): Measured at 1.3 meters above ground level, DBH is expressed in centimeters (cm) and represents the girth of the tree trunk. It is a standard and widely used parameter for assessing tree size and growth.Tree Height: The total vertical height of each tree, measured from the base to the top, recorded in meters (m). This variable provides information on vertical growth and site productivity.Tree Volume: The estimated volume of individual trees, typically expressed in cubic meters (m³). Tree volume is calculated using DBH and height through standard allometric equations or volume models, and it reflects the timber yield potential of the species.The dataset may include multiple observations collected from different trees, plots, or experimental sites. These measurements are useful for:Developing allometric relationships between DBH, height, and volumeEstimating biomass and carbon stockAssessing growth patterns and productivitySupporting forest management and yield prediction models
