A nearly twenty-year effort by the Oregon Soil Science Society culminated in the legislature designating Jory soil as a state symbol. The society unofficially adopted Jory soil in 1993 as part of a nationwide effort by soil scientists to recognize soil's importance for agriculture and the environment. Members aligned with state representative Mitch Greenlick and with Richard Page, a descendent of the Jory family for which the soil was named. After a failed 2007 attempt, Greenlick ensured approval in 2011 by threatening to block unrelated legislation.
USDA soil scientists first identified the soil in 1970 on Jory Hill, which was named for 1847 Marion County pioneers James and Mary Jory. The red soil largely came from ancient volcanic basalt flows that originated in eastern Oregon. In the Willamette Valley, the rock weathered into a deep soil that drains well and is optimal for growing Christmas and filbert trees, berries, and other crops.
Jory soils generally support forest vegetation, dominantly Douglas fir and Oregon white oak. They are very productive forest soils. Many areas have been cleared and are used for agricultural crops. The Jory soils and the climate of the Willamette Valley provide an ideal setting for the production of many crops, including Christmas trees, various berries, filberts (hazelnuts), sweet corn, wheat, and many varieties of grass seed. The soils are suitable for the grapes used in the expanding wine industry.
Growing urbanization of the Willamette Valley is resulting in a great deal of pressure for development in areas of the Jory soils.

House Concurrent Resolution 3
Sponsored by Representative GREENLICK (Presession filed.)
Whereas soils produce food and fiber, recycle water, support
lush forests, yield bountiful grain and nut harvests, provide
range forage, sustain wildlife and foster urban development; and
Whereas the State of Oregon and its citizens benefit from a
rich and diverse soil resource that sustains agricultural, range,
forestry and urban economies; and
Whereas public awareness of Oregon's soil resource promotes
land stewardship and soil conservation, which benefit future
generations; and
Whereas Oregon has many unique soils due to interactions of
complex geology, varied climates and diverse biota; and
Whereas the various soils provide color, texture and patterns
to Oregon's landscape; and
Whereas Jory soil is easily distinguishable by its strikingly
red color on stable foothills; and
Whereas Jory soil exhibits distinctive characteristics and
features that illustrate soil formation, conservation and
management; and
Whereas Jory soil is representative of Oregon's diverse and
unique soil resource; now, therefore,
Be It Resolved by the Legislative Assembly of the State of
Oregon:
That we, the members of the Seventy-sixth Legislative Assembly,
designate Jory soil as the official soil of the State of Oregon.
