Book excerpt: This guidebook describes the Grass Mountain Research Natural Area, a 377-ha (931-ac) tract in the Oregon Coast Range. The area supports a grass bald complex surrounded by stands dominated by noble fir (Abies procera) and/or Douglas-fir (Pseudotsuga menziesii) in the overstory, and western hemlock (Tsuga heterophylla) in the understory.

Book excerpt: This guidebook describes the Grass Mountain Research Natural Area, a 377-ha (931-ac) tract in the Oregon Coast Range. The area supports a grass bald complex surrounded by stands dominated by noble fir (Abies procera) and/or Douglas-fir (Pseudotsuga menziesii) in the overstory, and western hemlock (Tsuga heterophylla) in the understory. The area also contains a small rock garden plant community along high-elevation ridges, and young Douglas-fir forest that originated from a wildfire. Headwaters of high-elevation, Oregon Coast Range streams are surrounded by noble fir forest and add to the site diversity.

Download or read book Natural Vegetation of Oregon and Washington written by Jerry F. Franklin and published by . This book was released on 1973 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major vegetational units of Oregon and Washington and their environmental relationships are described and illustrated. After an initial consideration of the vegetation components in the two States, major geographic areas and vegetation zones are detailed. Descriptions of each vegetation zone include composition and succession, as well as discussion of variations associated with environmental gradients. Three chapters treat the forested zones found in the two States. Major emphasis is on the distinctive mesic temperate forests found in western Washington and northwestern Oregon. The interior valley forests, shrub lands, and prairies found between the Coast and Cascade Ranges in western Oregon are treated in a single chapter as are subalpine and alpine mosaics of tree-dominated and meadow communities. Unusual habitats, such as areas of recent vulcanism, serpentines, and ocean strand, are individually described. Soils, geology, and climate are considered in broad outline in an early chapter and in greater detail within discussions of individual geographic areas and vegetation zones. Appendices are included for definition of the various soil types, scientific and common plant names, and a subject index. An extensive bibliography is included to direct the reader to other references.

Available in PDF, EPUB and Kindle. Book excerpt: In this poineering application of island biogeography theory, Harris presents an alternative to current practices of timber harvesting. "Harris pulls together many threads of biological thinking about islands and their effect on plant and animal survival and evolution. He weaves these threads into a model for managing forest lands in a manner that might serve both our short-term economic and social needs as well as what some people feel is our ancient charge to be steward of all parts of creation."—American Forests Winner of the 1986 Wildlife Society Publication Award

Available in PDF, EPUB and Kindle. Book excerpt: recruitment of adult plants in entire communities, and all of them focus on changes in total densities of A central issue of plant ecology is the understanding individuals and do not refer to changes in community of the relative role of different life history stages in structure (Moles and Drake 1999; Rebollo et al. successful plant recruitment. The consecutive stages 2001; Goldberg et al. 2001). This ?eld of research of seed, seedling, and adult are related to each other has hardly been explored empirically, and we think it in a complex way that largely depends on species and may reveal interesting mechanisms for the regulation the in?uence of physical and biological factors of individual density and species diversity in plant (Goldberg et al. 2001), for example, irrigation and communities. At the functional group level (which grazing. As a result of relationships between these sorts species according to common features), we stages, the consequences of an ecological factor expect differences depending on growth form depend on the way that its effects propagate onto the (grasses versus forbs) and depending on seed mass following stage of the recruitment process. As far as (differences between small-seeded, medium-seeded, we know, there are no published studies that have and large-seeded species). Some authors (Goldberg addressed this subject. et al. 2001; Rebollo et al. 2001) studying annual In this article, we characterize the relationships plant communities have found greater seedling between the three plant developmental stages.
