Tree taper is the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. Within Forestry and for the purposes of timber production, trees with a high degree of taper are said to have poor form, while those with low taper have good form. The opposite is the case for open-grown amenity trees.
Example of hardware equipment for forest inventories: GPS and laser rangefinder for mapping connected to a field rugged computer. A timber cruise is a sample measurement of a stand used to estimate the amount of standing timber that the forest contains. These measurements are collected at sample locations called plots, quadrants, or strips.

Tree taper – the degree to which a tree's stem or bole decreases in diameter as a function of height above ground; Girard form class – an expression of tree taper calculated as the ratio of diameter inside the bark at 16 feet above ground to that outside the bark at DBH, primary expression of tree form used in the United States
Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...

A felled and delimbed tree is cut into logs of standard sizes, a process called bucking. A logger who specialises in this job is a buck sawyer. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of ...
Allometry studies the relative size of organs or parts of organisms. Tree allometry narrows the definition to applications involving measurements of the growth or size of trees. Allometric relationships often are used to estimate difficult tree measurements, such as volume, from an easily measured attribute such as diameter at breast height (DBH).
