From majestic Redwoods to ancient Western Bristlecone Pines, California's trees have long inspired artists, poets, naturalists—and real estate developers. Verna Johnston's splendid book, illustrated with her superb color photographs and Carla Simmons's detailed black-and-white drawings, now offers an unparalleled view of the Golden State's world-renowned forests and woodlands. In clear, vivid prose, Johnston introduces each of the state's dominant forest types. She describes the unique characteristics of the trees and the interrelationships of the plants and animals living among them, and she analyzes how fire, flood, fungi, weather, soil, and humans have affected the forest ecology. The world of forest and woodland animals comes alive in these pages—the mating games, predation patterns, communal life, and the microscopic environment of invertebrates and fungi are all here. Johnston also presents a sobering view of the environmental hazards that threaten the state's trees: acid snow, ozone, blister rust, over-logging. Noting the interconnectedness of the diverse life forms within tree regions, she suggests possible answers to the problems currently plaguing these areas. Enriched by the observations of early naturalists and Johnston's many years of fieldwork, this is a book that will be welcomed by all who care about California's treasured forests and woodlands.

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.

The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.

Evapotranspiration cools the land surface by consuming a large fraction of the net radiative energy at the surface. In forested regions, trees actively control the rate of transpiration by modulating stomatal conductance in response to environmental conditions, and species with different stomatal dynamics can affect the atmosphere in distinct ways. Using principal component analysis (PCA) and Markov chain Monte Carlo (MCMC) parameter estimation with direct, tree-level measurements of water use, we show that Douglas-firs (Pseudotsuga menziesii), a common evergreen needleleaf tree species in the Northern California Coast Range, decrease their transpiration sharply in the summer dry season in response to a dry root zone; and in contrast, broadleaf evergreen tree species, especially Pacific madrones (Arbutus menziesii), transpire maximally in the summer dry season because their transpiration is much less sensitive to a dry root zone and increases continually in response to increasing atmospheric evaporative demand. We scale up these tree-level observations to construct a bottom-up estimate of regional transpiration, and we use these regional estimates along with atmospheric models, one simple and one comprehensive, to quantify the potential impact of species transpiration differences on regional summertime climate. The atmospheric models suggest that these species differences in transpiration could affect the well-mixed atmospheric boundary layer temperature and humidity by 1-1.5 degrees C and 1 g/kg, respectively, and near-surface temperature and humidity by 1.5-2.5 degrees C and 2-3 g/kg, respectively. We further investigate the sensitivity of California climate to evapotranspiration by estimating the sensitivity of wind energy forecasts at a California wind farm to regional-scale perturbations in soil moisture using a regional atmospheric model. These tests show that forecasts at this particular farm are most sensitive to soil moisture in the Central Valley, and that changes in soil moisture on the order of previously-demonstrated errors in atmospheric reanalyses lead to wind energy forecast errors of 1-3 m/s, which can translate to differences in forecasted wind energy of 15-40% of a wind farm's maximum rated power.
