Excerpt from Results of Shelterwood Cutting in Western Hemlock Brush competition was not a serious problem in this area, averaging only 32-percent canopy density during the study. It appears, however, that the greatest densities of lesser vegetation that did occur under open stands inhibitedheight growth of hemlock seed lings somewhat.

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.

Book Description
Excerpt from Growth Response of Suppressed True Fir and Mountain Hemlock After Release Both diameter and height growth increased after release from two to four times the prerelease rate for both fir and hemlock. Acceleration of growth generally occurred within 5 years after release with the most rapid growth occurring on clearcut units. Growth curves had a sigmoid form showing constant growth before release, a rapid acceleration during the first 8 to 9 years after release, followed by a flattening of the curves from 10 to 20 years after release.
