Book Description
Excerpt from Forest Conditions in the Northern Sierra Nevada, California The area of high relief of the region may be considered as consisting primarily of the main range of the Sierra Nevada, a secondary chain of mountains to the east of it paralleling it at distances varying from 10 to 20 miles. From these ranges proceed in all directions a multitude of ridges, which together constitute the mountain system of the region. The main uplift of the Sierra is a continuous northwest-southeast range, and forms the geographic divide throughout most of the region. In the northern part of the Downieville quadrangle it is cut through by the Middle Fork of Feather River. Which heads in the eastern range. The summit of the Sierra varies in elevation; most of it rarely falls below feet. South of Donner Pass numerous peaks rise to altitudes of over feet, while Mount Lola reaches an elevation of feet. The eastern slope of the range is generally short and abrupt; its western slope is longer and has a more gradual descent. The Sierra has been subjected to glaciation in all portions above feet, and abounds in rocky and bowlder-strewn slopes, narrow summits, semicircular glacial basins, and tracts of bare rock from which all soil has been swept away. None of its peaks rise above timber line, although Castle Peak, at an elevation of feet, has a narrow line of perpetual snow on its northeastern slopes, and the higher peaks south of Donner Pass usually hold banks of snow throughout the summer on northern slopes in the lee of projecting combs.

Book Description
There has been widespread interest in applying new forest practices based on concepts presented in U.S. Forest Service General Technical Report PSW-GTR-220, "An Ecosystem Management Strategy for Sierran Mixed-Conifer Forests." This collection of papers (PSW-GTR-237) summarizes the state of the science in some topics relevant to this forest management approach, presents case studies of collaborative planning efforts and field implementation of these new practices, and clarifies some of the concepts presented in GTR 220. It also describes a method for assessing forest heterogeneity at the stand level using the Forest Vegetation Simulator and a new geographic information system tool for project-level planning that classifies a landscape into different topographic categories. While this collection of papers presents information and applications relevant to implementation, it does not offer standards and prescriptions. Forest management should be flexible to adapt to local forest conditions and stakeholder interests. This report does, however, strive to clarify concepts and present examples that may improve communication with stakeholders and help build common ground for collaborative forest management.

Book Description
In Fire in Sierra Nevada Forests, George Gruell examines the woodlands through repeat photography: rephotographing sites depicted in historical photographs to compare past vegetation to present. The book asks readers to study the evidence, then take an active part in current debates over prescribed fire, fuel buildup, logging, and the management of our national forests.

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.
