BOTANY

Detailed explanation-1: -Tree diameter is usually measured at 4.5 feet (ft) above ground level. Measurement at this height is referred to as diameter at breast height or DBH. DBH can be measured with a specially calibrated tape measure called a diameter tape (d-tape) available from most arborist or forestry supply dealers.

Detailed explanation-2: -The General Sherman Tree is the world’s largest tree, measured by volume. It stands 275 feet (83 m) tall, and is over 36 feet (11 m) in diameter at the base. Sequoia trunks remain wide high up. Sixty feet above the base, the Sherman Tree is 17.5 feet (5.3 m) in diameter.

Detailed explanation-3: -Main conclusions: Because large-diameter trees constitute roughly half of the mature forest biomass worldwide, their dynamics and sensitivities to environmental change represent potentially large controls on global forest carbon cycling.

Detailed explanation-4: -The bigger the tree’s diameter, the greater the amount of foliage it has. Tree diameter data can provide essential information about crown competition, stocking levels, and forest health. Stand management decisions, such as when and how much to thin a stand, rely heavily on data derived from measuring tree diameters.
