Author: Douglas-fir Tussock Moth
Author: Robert W. CampbellPublisher:
ISBN:
Category : Douglas fir
Languages : en
Pages : 176
Book Description
This annotated bibliography includes references to 338 papers. Each deals in some way with either the Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), or a related species. Specifically, 210 publications and 82 unpublished documents make some reference, at least, to the Douglas-fir tussock moth; 55 are concerned with other species in the same genus. The subject matter in each paper has been indexed to at least one general topic (General, Taxonomy, Biology, Host Relationships, Outbreaks, Control, Related Material). Most of these general topics have been subdivided into more specific headings. For example, Host Relationships includes separate categories for white fir, grand fir, and Douglas-fir. A complete listing of the references in each general and specific category is presented in the index.
A Guide to Conducting Aerial Sketchmapping Surveys

Category : Aerial surveys in forestry
Languages : en
Pages : 100
Book Description
The purpose of this guide is to describe general procedures used by experienced aerial survey specialists to collect forest health data via sketchmapping. It is not intended to be a specific "how to" manual for all types of aerial surveys, nor replace training in aviation safety and management, on-the-ground field training, or apprenticeship flight time during regular aerial surveys. Rather, it is a "guide" to the aspects of flying and sketching that make up sketchmapping, presenting a comprehensive overview of aerial overview surveys and a general review of aerial survey sketchmapping methodology.
