Book Description
Plantation Silviculture in Europe provides an up-to-date, succinct, and comprehensive overview of current European plantation forestry practices. Recognising that plantation silviculture today is no longer largely a question of how to grow large-scale industrial plantations, the authors have included chapters describing other, more diverse reasons for establishing trees. Forestry practices are set in the context of the science behind them and their environmental, social and policy frameworks. Concise and clear, this will be essential reading for forestry students and professionals alike. - ;As pressures to preserve natural forest resources have increased, plantation forestry and its study have gained in importance. Plantation Silviculture in Europe is an up-to-date, timely, and comprehensive exploration of the principles that underlie the planting and maintaining of forest resources. Based on the excellent reception of Savill and Evans' Plantation Silviculture in Temperate Regions (OUP, 1986), which was largely UK-based, the inclusion of two European authors ensures that the scope of this new book extends across the entire continent. Plantation Silviculture in Europe provides a thorough overview of the central aspects of conventional plantation forestry, covering site preparation, choice of species, establishment and maintenance, nutrition, spacing, thinning and pruning, and protection. In addition, it acknowledges the changing emphasis and increasing diversity of contemporary forestry, and includes chapters on community woodlands, urban forests, plantings for amenity and sport, and energy crops. Throughout, an attempt is made to set practices in the context of the ecological and biological forest processes which underpin them. Plantation Silviculture also incorporates discussion of the many environmental, social and policy issues that surround forestry today. Concise and clearly written, this will be essential reading for graduate and undergraduate forestry students and forestry professionals alike. Likely to become the standard text throughout Europe, it also contains much material of relevance to foresters in North America, East Asia, and Australasia. -

Book Description
This book is about how plants get diseases, from the origins and evolution of parasites to how the great plant epidemics developed. The basic premise of the book is that the conditions favouring disease are inherent in agriculture and that diseases become destructive because of human activities. It also deals with how people have dealt with plant diseases in history. Included in the book are the natural histories of some of the most damaging plant diseases, worldwide, with discussions of why each became destructive. Diseases are grouped according to the most significant factors in the development of epidemics: in every case this is due to a human factor. Discussion of each model disease proceeds from observable facts to more complex concepts; thus, the reader with little knowledge of plant pathology should find the book easily understandable.

Book Description
Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.

Book Description
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.
