Main Description
This book provides a comprehensive guide to the various methods by which roundwood and the products of roundwood are measured around the world. It presents and compares many different log scaling methods in terms of procedures and conversion ratios. Topics covered include grading logs, log manufacturing quality, statistical sampling methods and methods for determining log yard inventories and mill log usage volume. Detailed tables of data, covering characteristics, and log weight to volume ratios, are presented for the main commercial timber species of the world. The drivers of roundwood product recovery are also discussed and illustrated with numerous graphs and tables.

Reviews
• "The author has done an admirable job of systematically summarising a plethora of information on measuring roundwood. This comprehensive volume is sure to be invaluable to students and practitioners in forestry and forest products industries."
Harold E Burkhart, Virginia Tech, USA
• "This book is for anyone connected with the forestry profession, but especially for the student and the practitioner who must assimilate the bewildering array of measures and conversions that form the core of the practice. The clearly illustrated examples will ease the job of assimilating the intricacies of forestry measurements and serve as an irreplaceable reference throughout a career."
Henry Spelter, Economist, US Forest Service
