By providing multiple economic goods and ecosystem services, Latin American forests play a key role in the environmental, social and economic welfare of the region’s countries. From the tropical forests of Central America to the Mediterranean and temperate vegetation of the southern cone, these forests face a myriad of phytosanitary problems that negatively impact on both conservation efforts and forest industry. This book brings together the perspectives of several Latin American researchers on pest and disease management. Each chapter provides modern views of the status and management alternatives to problems as serious as the impact of introduced exotic insects and diseases on Pinus and Eucalyptus plantations throughout the continent, and the emergence of novel insect outbreaks in tropical and temperate native forests associated with global warming. It is a valuable guide for researchers and practitioners working on forest health in Latin America and around the world.

For hundreds of years, the massive ponderosa pine of the U.S. Southwest has left multitudes in awe. After spending nearly three decades researching among these trees, Sylvester Allred shares his wealth of experience in the southwestern ponderosa pine forests with the world in Ponderosa. Ponderosa is the first of its kind to provide an introduction to the natural and human histories of the ponderosa pine forests of the Southwest that is accessible to all who wish to enjoy the forests. The book offers knowledge on elemental aspects of the forests, such as the structure of the trees, as well as theoretical perspectives on issues such as climate change. Included are discussions of biogeography, ecology, and human and natural history, illustrated by over fifty color photographs throughout. Allred presents his observations as if he is recalling his thoughts over the course of a walk in a ponderosa pine forest. His imagery-saturated prose provides an informal and enjoyable approach to discovering the history and environment of the ponderosa pine. Using a concise, straightforward writing style, Allred invites readers to explore the forests with him. Ponderosa includes: More than 50 color photos Learn how to estimate the age of a tree See the reptiles, birds, and mammals that make their home in ponderosa pine forests Much more!

The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Insects are the most abundant and diverse organisms that inhabit our planet and are found in all the world’s forest ecosystems. Many feed and/or breed on parts of trees. Some perform important functions, such as pollination or break-down of dead vegetation. Others weaken, deform or kill trees, and compete with humans for the many goods and services that trees and forests provide. Forest Entomology: A Global Perspective examines forest insects in a global context and reviews their dynamics, interactions with humans and methods for monitoring and management of species that damage forests. Also provided are 235 profiles of forest insects, worldwide. A series of tables provides summaries of the distribution and hosts of many more species. Included are those that damage forests, others that are simply curiosities and some that are beneficial. This book is designed as a reference for students, practicing foresters and forest health specialists, especially for those who work internationally or are concerned with species that have the potential to expand their ranges via international trade, travel or environmental changes.

This field guide details the most commonly encountered diseases and insects of forest trees in the Rocky Mountain Region. Descriptions of diseases, insects, and physical injuries focus on the most diagnostic features of each. Photographs, line drawings, and tables are used to illustrate and emphasize characteristics described in the text. Diseases and insects in plains hardwood trees are not covered in depth. Ornamental trees are sometimes affected by the diseases or insects included in this guide but may not be specifically mentioned as hosts. This guide presents diseases and then insects. Entries are arranged according to the part of trees typically damaged by the agent described. The disease section describes dwarf and true mistletoes, decays (including root diseases and stem decays), cankers, wilts, rusts, foliage diseases, shoot blights, and abiotic injuries and miscellaneous diseases. The insect section describes bark beetles, defoliators, wood borers, sap-sucking insects, gall formers, mites, and bud and shoot insects. At the end of the guide is a subject index, a host-pest index to damaging agents by tree species and part of the tree affected, and a glossary of terms. The host-pest index provides a rapid means of assessing the number and variety of agents described for each tree species. This field guide applies to the USDA Forest Service's Rocky Mountain Region, which includes Colorado, Wyoming, South Dakota, Kansas, and Nebraska. Additional hosts, diseases, and insect pests may be encountered outside this Region that are not included here, and a few of the diseases and insects included in this guide may not be seen in other areas. Plant pathologists and entomologists are available to assist resource managers with identification of insects and pathogens encountered in the forests.
