An easy to understand non-laboratory based system for determining the causes of ill-health in trees. The emphasis is on problems of species grown for non-commercial purposes, but nearly all causes of ill-health in trees are covered on some detail, apart from damage from biting insects and mammals. Subjects covered include: diagnostic procedure, the known problems of virtually all tree genera used for amenity purposes in Great Britain; prevention and treatment of pests, diseases and disorders; decay and tree safety; and tree pest and disease legislation. Additions to the second edition include a major section of the identification of the principal wood-rotting fungi on trees, and items on water logging and exotic pests and diseases.

A large number of diseases and disorders can affect forest trees in Britain. Confidence in identifying particular causes from this range of potential problems requires a combination of knowledge and experience that is not easily acquired without becoming a specialist in the field. Part 1 of this book offers guidelines by which managers and owners can investigate health problems in their trees. Part 2 offers a key to the most common problems of plantation trees, and in Part 3 important features of some of the diseases and disorders covered in Part 2 are summarized.
Effective management of tree health problems depends on early detection and recognition of symptoms. This guide includes 140 photographs of symptoms from more than 50 tree species, which can be used as a basis for demonstrating the effects of pest (biotic) and non-living (abiotic) influences on trees. It is not designed as an identification guide to insect pests and diseases of trees, but rather seeks to enable a preliminary diagnosis and assessment of potential problems, in order to promote better planning and more effective management of forests and trees.
NEW YORK TIMES BEST SELLER • From the world's leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest—a moving, deeply personal journey of discovery Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in paperback, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths--that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own. Simard writes--in inspiring, illuminating, and accessible ways—how trees, living side by side for hundreds of years, have evolved, how they learn and adapt their behaviors, recognize neighbors, compete and cooperate with one another with sophistication, characteristics ascribed to human intelligence, traits that are the essence of civil societies--and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them. And Simard writes of her own life, born and raised into a logging world in the rainforests of British Columbia, of her days as a child spent cataloging the trees from the forest and how she came to love and respect them. And as she writes of her scientific quest, she writes of her own journey, making us understand how deeply human scientific inquiry exists beyond data and technology, that it is about understanding who we are and our place in the world.
Diseases of Shade Trees provides an introduction to tree diseases for students and others concerned with the care of shade and ornamental trees. Diseases of woody plants fall into two major categories: infectious diseases and noninfectious diseases. Part I of the book presents the infectious pathogens and the diseases they cause. These include bacteria, mycoplasmas, nematodes, seed plants, and viruses. The nature of the fungi is also presented, with separate chapters for leaf, root, rust, stem, and wilt diseases caused by fungi. Wound diseases, which are associated with both fungi and bacteria that invade wounds, are included in this section. Part II deals with noninfectious agents and the diseases they cause. Noninfectious agents are separated into environmental stress, animal injury, and people-pressure diseases. Diebacks and declines—complex diseases, which are often caused by a combination of both infectious and noninfectious agents are also included in this section. Part III on special topics includes discussions of nonpathogenic conditions often mistaken for diseases; diagnosis of tree diseases; and living hazard trees.
The aim of this publication is to provide information for assessing and managing risks to people and property, and also to protect trees from unnecessary felling and disfigurement. Key features: Provides information for assessing and managing risks to people and property rovides information on protecting trees from unnecessary felling and disfigurement
The Second Edition of this classic text is completely up-to-date with new chapters, new information on diseases, updated citations, and revised taxonomy and terminology of the fungi, bacteria, and other organisms that affect trees. Field and Laboratory Guide to Tree Pathology presents field and laboratory techniques as well as basic information for students, foresters, plant scientists, and arboriculturalists on tree disease pathology. The revised edition includes expanded historical documentation, updated taxonomy and terminology for both pests and diseases, an entirely new introduction, new chapters on tree biology, general control strategies, and diagnostic techniques. A new section of color plates will help readers in the identification of tree pathogens. All the references have been comprehensively updated, and the exercises included for students have been revised, making this guide a useful tool for students, teachers, and practitioners interested in tree disease. Contains new chapters on tree biology, general control strategies, and diagnostic techniques Includes additional information on the histories of disease Provides thoroughly updated citations Contains comprehensively revised taxonomy and terminology
Although she is saddened that storm damage has caused her to lose some of her branches, Little Tree draws strength and happiness from the knowledge that she still has a strong trunk, deep roots, and a beautiful heart.
