Book Description
Excerpt from Disintegration of Girdled Western Hemlock and Grand Fir The occurrence of overmature defective trees is responsible for some of the most difficult management problems in the western white pine type. Grand fir and'western hemlock in particular are highly susceptible to Woodarotting fungi. In addition, because of their shade tolerance, they often inhibit or prevent establishment and growth of the more desirable but less shade-tolerant species such as western white pine. Hence, many of the management practices for the white pine type provide for the re moval of trees of undesirable form, condition, or species. Girdling is one method of removing such trees. This method was exten sively used by the U. S. Forest Service between 1915 and 1930 on timber sales in the western white pine type. Although girdling lowhvalue trees 'was discontinued as a stand improvement measure after 1930 because of the high fire hazard of the resulting snags (figure there were reasons to consider the method worthy of further study. For example, it is a com paratively cheap and effective'way to destroy an occasional large tree, such as a wolf tree which is suppressing desirable reproduction. Tests 2/ 1tere made, accordingly, to determine the effect of girdling on cone pro duction, mortality, rate of disintegration of trees, end.damage to repro duction. Results of these studies are described in this report. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Highly adaptable to the manufacture of paper pulp, the species vies with western hemlock and Douglas-fir as a leading source of pulpwood in the Pacific Northwest. Principal uses of the lumber are for fram ing and sheathing in house construction, and for box shook. The species is planted as an ornamental Shade tree in parts of eastern United States and western Europe. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Silvical Characteristics of Noble Fir Noble fir is restricted in its natural range to the mountains of the Pacific Northwest (fig. On the eastern slope of the Cascade Range, it occurs north of about latitude 45 degrees and only at higher elevations. On the west side of the Cascades, where it is most abun dant, and in the Coast Range, where it occurs sparsely, it grows be tween 1, 400 and 6, 000 feet elevation, extending in the Cascades from the Canadian border to northern California. In the Coast Range, it is found only in southwest Washington and northwest Oregon. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
