We merged the soils GIS coverages obtained
from
NRCS and OSU
Soil Science Department websites to create a single soils
coverage for the entire study area. This layer was fairly
complete; however, soils information for Tillamook County
was not available.
There are more than 350 soil types in the region Major
soil groups are shown in the figure at the right.
We then intersected this soils layer with the 6th fields
layer to attribute each soils polygon with the appropriate
6th field identifier. We joined the
hydric
components and
soils erosion
risk tables (from downloaded Map Unit Interpretations
Record Tables).
The definition of hydric soils is established
by the National Technical Committee on Hydric Soils.
