Description: Forest resources in Washington and Oregon were surveyed in the early
1930s by employees of the Pacific Northwest Experimental 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.
The 27 forest cover types defined are the result of the combination and
generalization of some 50 types used by the Forest Survey in mapping all
forest land in Oregon and Washington. In addition to the 50 primary
cover types, all immature stands were differentiated according to age in
10 year classes and according to their density of three degrees of
stocking, namely, good, medium and poor. None of this detail of age of
stocking is shown on this map; such types may include any or all degrees
of stocking. The complete type mapping, using all the detail of the
original field work, has been reproduced for every county in Oregon and
Washington in the form of uncolored blue line prints, scale one inch to
the mile, which show type boundaries, type numbers and age and stocking
symbols. These county maps may be obtained from the PNW Forest
Experiment Station, US Court House, Portland, Oregon.
