Book Description
After a brief description of silvicultural problems, the author tells how to prescribe herbicidal sprays for aerial, application in Pacific Northwest forests. The publication offers a detailed discussion of the five basic considerations: (1) selection of the best herbicide or herbicides, (2) amount of herbicide to be applied per acre, (3) carriers, (4) volume of spray per acre, and (5) seasons for application of aerial sprays. Appendixes provide standard treatments for many common silvicultural problems in site preparation and to release young conifers from shrub and weed tree competition. Also included is a glossary of agricultural chemical terms and a list of abbreviations used in brush control literature. This is a working manual for silviculturists based upon more than 20 years research and experience of Federal, State, and industrial foresters. It provides much information not generally available in the literature and tells how to use this knowledge in Pacific Northwest silviculture. Although designed primarily for the Pacific Northwest, the basic information should be useful in culture of coniferous forests far outside this region.

Silvicultural Research and the Evolution of Forest Practices in the Douglas-fir Region
Author:
Publisher:
ISBN:
Category : Douglas fir
Languages : en
Pages : 176
Book Description
Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.
