Permanent Plot Procedures For Silvicultural And Yield Research

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.

"It is the purpose of the circular to present to foresters with research responsibilities an outline of the technic of sample-plot procedure in order that the standards of the work may be raised, that the findings from studies of data obtained in one region may be applicable in other regions, and that silvicultural research as a whole may yield conclusive results in less time."--Page 3
