This book is the only comprehensive summary of natural resources of
Oregon and adds to World Soil Book Series state-level collection.
Due to broad latitudinal and elevation differences, Oregon has an
exceptionally diverse climate, which exerts a major influence on
soil formation. The mean annual temperature in Oregon ranges from
0°C in the Wallowa and Blue Mountains of northeastern Oregon to 13
°C in south-central Oregon. The mean annual precipitation ranges
from 175 mm in southeastern Oregon to over 5,000 mm at higher
elevations in the Coast Range. The dominant vegetation type in
Oregon is temperate shrublands, followed by forests dominated by
lodgepole pine, Douglas-fir, and mixed conifers, grasslands,
subalpine forests, maritime Sitka spruce-western hemlock forests,
and ponderosa pine-dominated forests. Oregon is divided into
17 Major Land Resource Areas, the largest of which include the
Malheur High Plateau, the Cascade Mountains, the Blue Mountain
Foothills, and Blue Mountains. The single most important geologic
event in Oregon was the deposition of Mazama ash 7,700 years by the
explosion of Mt. Mazama. Oregon has soil series representative of
10 orders, 40 suborders, 114 great groups, 389 subgroups, over
1,000 families, and over 1,700 soil series. Mollisols are the
dominant order in Oregon, followed by Aridisols, Inceptisols,
Andisols, Ultisols, and Alfisols. Soils in Oregon are used
primarily for forest products, livestock grazing, agricultural
crops, and wildlife management. Key land use issues in Oregon are
climate change; wetland loss; flooding; landslides; volcanoes,
earthquakes, and tsunamis; coastal erosion; and wildfires.
