Book Description
Excerpt from The Economics of Converting Red Alder to Douglas-Fir A premise of this study is that the forest manager sees red alder as a problem. Compared with Douglas-fir, red alder is a Johnny - come-lately that many foresters feel is unworthy of serious consideration. Others consider the species to be a real economic windfall. In any case, we are here interested in developing analytical approaches that will permit managers to make rational decisions regarding the retention or replacement of red alder stands. Conversion of a young red alder stand to Douglas-fir requires a relatively large capital outlay that may be wholly or partially avoided by a few years' wait for the stand to reach merchantable size. The length of this waiting period de pends on the productivity of the site. The financial returns depend on the direct costs of conversion, management costs, the anticipated harvesting regime, fu ture prices, and the firm's Opportunity cost of capital. Thus, the two simple alternatives of retaining red alder or converting to Douglas-fir lead to numerous investment management possibilities.

Excerpt from Seasonal Progress of Radial Growth of Douglas-Fir, Western Redcedar and Red Alder Trees were chosen to minimize variations in crown class and diameter. Most were strong codominants.

Book Description
Excerpt from Red Alder, Its Management and Utilization Alder grows both in pure stands and in mixture with native coni fers and hardwoods. When growing in mixture, it is nearly always in a dominant or codominant position. Stands are predominantly even aged, whether pure or mixed, since alder is usually the first tree to originate in openings. Because of its intolerance, it rarely fills in after a stand has been established. Mixtures occur only in young-growth coniferous stands less than 100 years old; however, alder may occur in openings in older stands. Only on sites best suited for alder growth does it succeed itself. Characteristic tree associates are Douglas-fir,3 western redcedar, western hemlock, grand fir, Sitka spruce, bigleaf maple, vine maple, Pacific willow, bitter cherry, and black cottonwood. Given time, conifers will often attain dominance as the alder canopy breaks up because of age, disease, or insects.

Book Description
Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.

Book Description
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
