"It is the purpose of the circular to present to foresters with research responsibilities an outline of the technic of sample-plot procedure in order that the standards of the work may be raised, that the findings from studies of data obtained in one region may be applicable in other regions, and that silvicultural research as a whole may yield conclusive results in less time."--Page 3

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.
