Estimation of log volumes : a comparative study / C. Li … [et al.]. : Fo148-1/11E-PDF

"Log volume estimation is a central topic in forest science research and forestry practice because accurate estimates are essential for commercial harvesting, sustainable forest management, and conservation. To determine whether the log volume estimates obtained using different commonly used log volume models are consistent, we reviewed major log volume estimation methods and conducted a comparative study using data from six different treatments of a commercial thinning experiment in the Boreal Plains Mixedwood Fibre Initiative project. There were significant differences in the log volume estimates we obtained using the different methods under simulated tree-length harvesting conditions. However, these differences were reduced when the section length of a log was decreased and the stem volume was calculated as the sum of all sections under simulated cut-to-length harvesting conditions, and only minor differences were observed when the section length was decreased below a certain threshold section length"--Abstract, p. iii.
