Geometrical Analyses of Plantation Logs: Taper, Bow, Crook, Pith Eccentricity, and Ovality

In plantation forestry, quantitative analyses of the commodity are essential to precisely evaluate the productivity and economics of the industry. The accurate assessment of the yields can only be achieved if the parameters of logs are measurable. The analyses of the diameter, cross-sectional area and volumetric calculation of plantation logs are described in Timber Technology Bulletin No. 104. Also, the measurements and analyses of bark and sapwood/heartwood proportion of logs are explained in Timber Technology Bulletin No. 111. This article is a quick reference for the recommended methods of analyses and quantification with regards to the taper, bow, crook, pith eccentricity and ovality of plantation logs.
