LRU notes
Major land resource area (MLRA): 043A-Northern Rocky Mountains
Modal LRU – 43A09 Western Bitterroot Foothills
This LRU is composed predominantly of mid-elevation foothills, mountain slopes, ridges, valley walls, plateaus, and low elevation foothills, canyons, structural benches, valleys, and escarpments. The soils tend to be loamy vitrands, and cryands. Quartzite and other metamorphic deposits are the dominant parent materials. Soil climate is a mesic to frigid temperature regime and xeric to udic moisture regime with average annual precipitation around 895 mm (35 inches).
Others where occurring – 43A10 – Clearwater Mountains
Classification relationships
This ES group fits into the National Vegetation Standard’s Vancouverian-Rocky Mountain Montane Wet Meadow & Marsh. (Compare to previous Idaho range site: R009XY018ID, MEADOW)
Ecological site concept
This ES is found on poorly drained loamy mineral soils in drainageways with a water table within 24 inches of the surface and a plant community dominated by grasses and forbs and some shrubs. The sites have a cryic temperature regime due to cold air drainage from surrounding mountains.
