Comparison of Hossfeld's Method and Two Modern Methods for Volume Estimation of Standing Trees
Abstract:Two modern methods, centroid sampling and the paracone model, have been shown to be accurate approaches for obtaining the volumes of trees and logs when taper functions are unavailable or local volume estimates are desired. We show that the equation for whole-tree volume using Hossfeld's method, an older method that has all but disappeared from the North American literature, is nearly identical to that for centroid sampling and the paracone model. Hossfeld's method may be slightly simpler to implement in the field, and like the modern methods, it can be used either for whole trees or for unmerchantable tops. In comparison with detailed measurements taken on 186 ponderosa pine trees from the Black Hills of South Dakota, the paracone model was most accurate for whole trees, but Hossfeld's method was slightly more accurate than centroid sampling. Hossfeld's method was substantially more accurate than either modern method for estimating the volume in tops.

- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
