Abstract

To assess the adequacy of a permanent-plot data base for estimating growth and yield, one first needs to know how the plots in the data base are distributed in relation to the population they are presumed to represent. The distribution of permanent plots to study forest growth in the Inland Empire (northeastern Washington, northern Idaho, and western Montana) is displayed using a method that relates the permanent plots to the land base. The permanent plots are quantified into classes defined using inventory data that describe the land base. Five stand attributes are used to define the classes: geographic location, habitat type, aspect, slope, and elevation. The assessment also includes the silvicultural treatments of the plots.
