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

The data were collected from subtropical forest ecosystems of Kangra district, Himachal Pradesh, India, and are intended to support forestry research, biomass estimation, and growth and yield modeling studies.The dataset comprises three major variables:Diameter at Breast Height (DBH): DBH was measured at 1.3 m above ground level and recorded in centimeters (cm).

It represents the girth of the tree trunk and serves as a standard indicator of tree size, stand structure, and growth performance.Tree Height: Total tree height was measured from the ground surface to the topmost point of the tree and recorded in meters (m). This parameter reflects vertical growth and provides insights into site quality and productivity.Tree Volume:Individual tree volume, expressed in cubic meters (m³), was estimated using DBH and height through standard allometric or volume equations.
