Synopsis

This field guide is a forest management tool for field identification of biotic and abiotic agents that damage native trees in Colorado, Kansas, Nebraska, South Dakota, and Wyoming, which constitute the USDA Forest Service's Rocky Mountain Region. The guide focuses only on tree diseases and forest insects that have significant economic, ecological, and/ or aesthetic impacts; this guide does not necessarily cover all possible damage agents. Management suggestions are provided where available. The field guide is divided into two sections: one describes both diseases and damage caused by animals and abiotic factors, and the other describes insects. Agents are presented by the type and/or location of the injury on the tree. Written descriptions, color photographs, a general index, an index by host tree species, descriptive tables, and line drawings are all provided to assist users in identifying damaging agents.

A propos du livre

Présentation de l'éditeur

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.
