Excerpt from Natural Reproduction of Grand Fir and Mountain Hemlock After Shelterwood Cutting in Central Oregon Recognizing that shade - tolerant Species found in the fir - hemlock type might regenerate better after partial cutting, the Deschutes National Forest began using the shelterwood method in 1971. This paper reports the natural regeneration of grand fir (abies grandis (dougl.) Lindl. And mountain hemlock (tsuga mertensiana (bong.) Carr.) following a good seed year in response to variations in density of the residual stand. 2. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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
Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.
