Title: Use of dominant tree heights in determining site index for Douglas-fir.

Author: Staebler, George R.;

Date: 1948

Source: PNW Old Series Research Notes No. 44, p. 1-3

Publication Series: Miscellaneous Publication

Description: Measuring heights of Douglas-fir trees for the determination of site index is a time-consuming job, especially in dense stands. Both dominant and codominant trees must be measured since site index curves represent the average height of dominants and codominants. It has been suggested that considerable time might be saved if only dominant trees were measured, since these trees extend above the general crown level and are frequently in or at the edge of openings; hence, their tops are much more easily spotted from a distance.
