Silviculture and ecology of western U.S. forests by J. C Tappeiner( Book )

9 editions published between 2007 and 2015 in English and held by 215 WorldCat member libraries worldwide

Once regarded mainly as the cultivation of forest trees, silviculture is today shifting to a broader focus, one that reflects society's changing forest values. In addition to timber management, the practice and science of silviculture are now concerned with tending forests--to maintain forest health and reduce fire potential, benefit wildlife, and maintain aesthetics--and with ensuring options for future uses of the forest. Silviculture and Ecology of Western U.S. Forests follows the progression of silviculture as a science and looks closely at the value of forests. The only silviculture text to focus on the forests of the western U.S., primarily those in Oregon, Washington, and California, it is based on over 900 references as well as the authors' research and management experience

Stand development and individual tree morphology and physiology of young Douglas-fir (Pseudotsuga menziesii) in association with tanoak (Lithocarpus densiflorus) by Timothy Harrington( Book )

1 edition published in 1989 in English and held by 1 WorldCat member library worldwide

Effects of tanoak (Lithocarpus densiflorus) on early growth, morphology, and physiology of Douglas-fir (Pseudotsuga menziesii) were studied to determine developmental characteristics of young stands and mechanisms of competition. Growth, leaf area, and biomass of Douglas-fir, tanoak, and shrubs / herbs were monitored for six years after establishing a gradient of tanoak cover with and without suppression of shrubs / herbs. Growth trajectories for Douglas-fir and tanoak were related to initial tanoak cover, a variable that can be predicted using inventory data from the pre-harvest stand. Morphology, duration, and relative rates of growth of Douglas-fir were studied for three growing seasons to determine how the accumulating effects of competition caused tree size to vary. Tanoak competition reduced the size and number of buds, internodes, and needles for Douglas-fir shoots. In a given year, Douglas-fir growth was limited by competition in previous years via reduced potential growth (i.e., internode number for shoot growth and stem circumference for diameter growth) and by competition in the current year via reduced attainment of potential growth (i.e., expansion of internodes and basal area growth per unit stem circumference). To describe mechanisms of competition, variables of microclimate (air / soil temperature, light, and soil water) and physiology (xylem pressure potential, conductance, and photosynthesis) were measured in each of eighteen consecutive months on Douglas-fir of different competitive status. Throughout the year, Douglas-fir shaded by tanoak had light-limited rates of photosynthesis. During the growing season, both shaded and unshaded Douglas-fir in tanoak-dominated areas experienced elevated leaf temperatures, lower relative humidities, and reduced soil water availability, resulting in limited rates of photosynthesis
Prediction of the biomass, leaf area, and crown area of sprout clumps of tanoak (Lithocarpus densiflorus (Hook. and Arn.) Rehd.) : a technique for assessing site occupancy by this species by Timothy Harrington( Book )

1 edition published in 1982 in English and held by 1 WorldCat member library worldwide

Tanoak (Lithocarpus densflorus (Hook and Am.) Rehd.), an evergreen hardwood tree that grows abundantly in southwest Oregon and north California, sprouts vigorously after a disturbance, such as logging or fire These sprouts form clumps that can hamper conifer regeneration on clearcuts and in shelterwoods. In order to obtain a quantitative measure of the site occupancy by tanoak sprout clumps, aboveground biomass and leaf area were estimated for a range of sprout clump sizes of age 1 to 6. Both variables were linearly correlated with the diameter of the original parent tree at breast height (dbh). Equations were developed for predicting sprout clutnpbiomass, leaf area, and crown area through age 6 from the dbh of the original parent tree. Thus, by knowing the diameters of tanoak trees prior to cutting, the bioinass, leaf area, and crown area of the developing sprout clump stand can be predicted up to 6 years after cutting. Biomass and leaf area were also linearly correlated with crown area. This permits the estimation of tanoak site occupancy (i.e., biomass/ha, leaf area index, and percent crown cover) in existing brushfields, based on measurements of clump size derived from aerial photos or ground surveys. Examples of the use of these methods are included
