Book Description
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.

Book Description
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.

Book Description
Grasses: Systematics and Evolution is a selection of the very best papers from the Proceedings of the Third International Symposium on Grass Systematics and Evolution held in Sydney, Australia in 1998. The papers represent some of the leading work from around the world on grasses and include reviews and current research into the comparative biology and classification. All 41 papers have been peer-reviewed and edited.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
