Abstract:

The total heights of 35 Douglas-fir trees [Pseudo tsuga menziesii (Mirb.) Franco] were measured with a sectional measuring pole, a Haga altimeter, and an alti-level. After the trees were measured by all three methods, they were felled and carefully measured. The sectional pole proved significantly more accurate than the alti-level, which was more accurate than the Haga altimeter. Because the sectional pole was only slightly slower to use than the other two indirect methods, it should be useful for inventory or research work.
