Abstract The initiation in the Douglas fir region of the great nation-wide forest survey and its progress to date has been followed by foresters with the greatest interest, and many inquiries have been made as to the technic being employed. In this article, Mr. Andrews, in charge of the forest survey in the Douglas fir region, gives a resume of the problems met with in drawing up the plans for the survey, such as judging the value of existing data, the standards of cruising methods to be adopted and the classification systems for forest types, accessibility zones, and ownership groups. He describes the plan adopted and how it is applied in detail. His paper is limited largely to the inventory phase of the work.
H. J. Andrews (Tue,) studied this question.
