Recommended preparation

MTH 102 or a course from the foundational requirements math list; FOR 235 and FOR 236. Recommended to be taken with

Course Description

Includes instruction in log scaling, tree measurement techniques, sampling statistics, tree volume and tree taper equations, sampling and field procedures for equal probability (sample tree and fixed area) and variable probability (3P and point sampling) sampling systems. Concludes the sequence of FOR 235, FOR 236, and FOR 237.

Course learning outcomes

1. Explain the need for, benefits of, and disadvantages of sampling.
2. Determine the volume of trees using standard volume tables, local volume tables, form class tables, tariff tables, regression analysis, and volume/basal area ratios.
3. Explain the difference between gross and net volume and the causes and indications of volume loss after harvesting a timber stand.
4. Explain the basic concepts of sample tree, strip cruising, and 3P sampling.
5. Cruise a stand of timber using random or systematic sampling using fixed or variable plot methods and report the results.
