Field Guide to Diseases and Insects of the Rocky Moutain Region
Author: United States Department of Agriculture
Publisher: CreateSpace
ISBN: 9781506140254
Category :
Languages : en
Pages : 346
Book Description
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.

Author: Yasuyuki Hiratsuka
Publisher: Special Report
ISBN:
Category : Science
Languages : en
Pages : 40
Book Description
This field manual describes and illustrates external indicators of decay and stain and other stem abnormalities of aspen (Populus tremuloides Michx). It describes how to identify, measure, and record internal defect, and how to calculate pulp cull volume. Major types of wood defects include Type A1 and A2 (Phellinus tremulae [Bond. Bond. & Borriss.), Type B (Armillaria sp.), Type C (Peniophora polygonia [Pers.:Fr Bourd. & Galz.), Type D (Stain by biotic and abiotic factors), and Type E (stain stored in logs). The use of a wood hardness measuring device (H-Gun) to distinguish between pulpable and non-pulpable Type A1 and A2 decayed wood is also outlined.
