The 1930s survey of forest resources in Washington and Oregon.

Abstract

Forest resources in Washington and Oregon were surveyed in the early 1930s by employees of the Pacific Northwest Forest Experiment Station (the original name of the current Pacific Northwest Research Station). This was the first of many periodic forest surveys conducted nationwide by the USDA Forest Service. Many publications and maps were produced from the Washington and Oregon 1930s survey data. Forest cover maps created from that data (at an original scale of 1:253,440) have recently become available in digital formats, but little documentation was provided with the electronic files, and the older publications are not readily available to most users. This report provides a brief overview of the survey and reprints excerpts from, or complete versions of, early publications that dealt with the planning, conduct, or results from the survey. A list of county-level maps, prepared at a scale of 1:63,360, that have been located is also included. A companion CD-ROM includes (1) the overview of the survey and the early publications in PDF format, (2) a link to the free Adobe Acrobat® Reader to enable users to read the PDF files, (3) the forest type maps in several geographic information system (GIS) or graphics formats (ArcView^TM shape files, ArcExplorer^TM project files, and .jpg, a graphics file format), and (4) a copy of ArcExplorer^TM (to view and print the ArcExplorer^TM files).

Information from the original CD‑ROM has been reformatted into an interactive map: https://research.fs.usda.gov/pnw/products/dataandtools/1930s-survey-forest-resources-washington-and-oregon-interactive-map
