LRU notes
Modal LRU – 43A01 Okanogan Plateau
This LRU is composed predominantly of mid to high elevation mountain slopes. The soils are loamy Xerolls,, Xerands or Xerepts with ashy surfaces. Till from sedimentary or other rock is the dominant parent material. Soil climate is a frigid or cryic temperature regime and xeric moisture regime with average annual precipitation around 470mm (19 inches).
Others where occurring - 43A03 - Columbia-Colville Valleys
43A04 - Selkirk Mountains
44A02 - Pend Oreille-Kootenai Valleys

Ecological site concept
Ecological Site Concept:
The data below describes the physiographic, climatic and other parameters for the Quaking Aspen/ Common Snowberry. This vegetation alliance is geographically widespread though individual stands are often small. It frequently occurs as an inclusion in more extensive ecological types. Soils are loamy with mixed volcanic ash surfaces. Water tables are high (generally within 24 inches of the surface) and available water holding capacity is moderate to high.
