Download or read book Characteristics of Remnant Old Growth Forests in the Northern Coast Range of Oregon and Comparison to Surrounding Landscapes written by Andrew N. Gray and published by DIANE Publishing. This book was released on 2011-05 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Old-growth forests provide unique habitat features and landscape functions compared to younger stands. The goals of many forest mgmt. plans in the Pacific NW include increasing the area of late-successional and old-growth forests. This study describes existing old-growth forests in the northern Oregon Coast Range that might serve as examples of desired future conditions and developmental pathways. Results suggest that although old-growth forests can develop along multiple pathways, stand composition and productivity constrain development such that expecting all late-successional stands to have the full complement of old-growth attributes may not be realistic.

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.
