Book Description
The hydrology of small forest streams in western Oregon varies by time and space in terms of both streamflow and channel hydraulics. Overland flow rarely occurs on undisturbed soils. Instead, water is transmitted rapidly through soils to stream channels by displacement of stored soil water. Drainage networks expand and contract according to the interaction between precipitation characteristics and soil's capability to store and transmit water. Drainage networks are more extensive in winter than in summer. Streamflow may he 1,000 to 5,000 times greater during winter storms than during summer low flow. A stream's kinetic energy varies along with streamflow. Channel width and depth, heterogeneity of bed materials, and the accumulation of large, organic debris affects the dissipation of kinetic energy. Clearcutting can increase relatively small peak flows, but forest roads and extensive areas of soil compacted by other means may increase larger peak flows. Both roadbuilding and clearcutting can cause soil mass movements, which can drastically alter a stream's channel hydraulics by adding debris or scouring the charnel to bedrock. Removal of naturally occurring organic debris that has become part of a stable channel can accelerate bed and bank erosion.

Book Description
Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

Book Description
This is the definitive fire history of Oregon Coast Range forests, woodlands, savanna's, and grasslands for the past 500 years. Its comprehensive research methods, references, and recommendations serve as a model for other landscape-scale fire histories and is primarily why it is being updated and reprinted at this time.
