The Forest Surv 



ey 



DEPENDABLE information on the supply of forest products, as of all raw materials, 

 is vital to the conduct of the war and to any plans for our postwar welfare. Intelligent 

 land-use planning must be based upon reliable facts as to location, area, and con- 

 dition of existing and prospective forest land, supply of timber and other forest products, 

 forest depletion and forest growth, and production and consumption of forest products. 

 This necessity for dependable and comprehensive data is now being met through the 

 Nation-wide forest survey authorized by the McSweeney-McNary Forest Research Act 

 of 1928. The Forest Service was directed by the Secretary of Agriculture to conduct 

 the survey. The rapidly changing conditions of our economic and social life since the 

 second world war began have accentuated the need for publishing the facts already 

 gathered and the conclusions to be drawn from them. 



The fivefold purpose of the Forest Survey is : ( 1 ) To make an inventory of forest land 

 and timber supplies; (2) to ascertain the current and potential growth on forest areas; 

 (3) to determine the drain upon the forests through cutting and through loss from fire, 

 insects, disease, wind throw, and other causes; (4) to determine the present and prospective 

 requirements of the United States for forest products; and (5) to analyze and correlate 

 these findings with other economic data, as an aid in formulation of private and public 

 policies for most effective and rational use of land suited to forest production. 



In each forest region of the United States the forest survey is conducted by the regional 

 forest experiment station. The survey of Oregon and Washington has been made by the 

 Pacific Northwest Forest and Range Experiment Station, with headquarters at Portland, 

 Oreg. 



The results of this investigation are published, as they become available, in a series o 

 reports applying to large forest areas such as regions, States, units, and counties. It is 

 expected that the information presented in these reports for large geographic units will 

 facilitate more intensive studies of small areas. Naturally, the recommendations made 

 are adapted to the long-time character of timber growing and presuppose normal peace- 

 time conditions. Any that are out of line with war requirements are obviously in abey- 

 ance for the present.
