This text is intended for introductory courses in forest measurements. Emphasis is on the measurement of timber, with detailed coverage on measuring products cut from tree boles, measuring attributes of standing trees, inventorying volumes of forest stands, and predicting growth of individual trees and stands of trees. Background information on statistial methods, sampling designs, land measurements, and use of aerial photographs is also provided. An introduction to assessing range, wildlife, water, and recreation resources associated with forested lands comprises the last chapter. The measurement principles and techniques discussed apply to any inventory that includes assessment of the tree overstory, regardless of whether the inventory is conducted for timber, range, wildlife, watershed, recreation, or other management objectives.
