Soil Survey Mapped At Two Levels Of Intensity1

This 1,040,000 acre Josephine County Soil Survey was mapped at two levels of intensity or detail. The more detailed part of the survey would be considered a 2nd order level and the less detailed part would be a 3rd order level. Soil map units in the 2nd order level are identified by field observation and by remotely sensed data. This data is considered intensive and can be used for general agriculture and urban planning. Map unit size is generally no smaller than 10 acres but could be as small as 4 acres. Soil map units in the 3rd order level usually have less field verification and more remotely sensed data than the 2nd order units. This data is considered extensive and can be used for range and community planning. Unit size is generally 40 acres or larger but could be as small as 4 acres.

The Soil Survey has 157,532 acres (15%) of 2nd order survey, 880556 acres (85%) of 3rd order survey, and 1,912 acres (0%) of water.2

Map scale of the published soil maps is 1:20,000. This scale equates to 1,666.7 feet per inch, 0.6 inches per 1,000 feet, 3.17 inches per mile or 63.77 acres per square inch.  Acreage and proportionate extent of each map unit is given in table 4 of the Soil Survey.

Value Of Survey

The 2nd Order Survey has more utility for land use proposals with land divisions to 5 acres or less than the 3rd Order Survey.  The following Josephine County mapping units have a 2nd Order Survey (check the Soil Survey to verify).

A careful and complete review of the map unit description is critical to proper use of soil survey data.

More Information

The Takelma Indians were the predominant group of people in Josephine County prior to the coming of the white men.  The only cultivated crop was tobacco.  The staple vegetables of the Takelmas were acorns, camas bulbs, manzanita berries, and sugar pine nuts.  Fish, deer, and elk were also used as food.
