Abstract

This paper reviews purposes and procedures for establishing and maintaining permanent plots for silvicultural and yield research, sampling and plot design, common errors, and procedures for measuring and recording data. It is a revision and update of a 1983 publication. Although some details are specific to coastal Pacific Northwest conditions, most of the material is widely applicable.

Keywords

Plot analysis, permanent sample plots, tree measurement, sample plot design, growth and yield
