Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bur Oak / Mixedgrass Loam Wooded Grassland
Colloquial Name: Great Plains Bur Oak / Mixedgrass Loam Wooded Grassland
Hierarchy Level: Association
Type Concept: This community type is found in the north-central portion of the Great Plains of the United States and Canada. Stands occur along the upper portions of river valleys slopes, ravines, and moraine hills. In North Dakota, this community occurs on nearly level to hilly glacial till uplands along the edge of the Turtle Mountains. The tree canopy of this community is open, with individual or clumped Quercus macrocarpa trees and scattered shrubs in a matrix of graminoid-dominated understory. Common shrubs include Symphoricarpos occidentalis and Prunus virginiana. Frequent grasses include Elymus canadensis, Nassella viridula, Pascopyrum smithii, Elymus trachycaulus, and Muhlenbergia racemosa. Forbs may include Anemone canadensis, Anemone cylindrica, Heuchera richardsonii, Vicia americana, Asclepias verticillata, and Galium boreale.

Classification Comments: This type is very poorly understood. Its range is west of the oak openings type ~Quercus macrocarpa Northern Tallgrass Wooded Grassland (CEGL002158)$$, which is found in the northern tallgrass region. It grades into ~Quercus macrocarpa / Corylus americana - Amelanchier alnifolia Woodland (CEGL000556)$$, particularly in the Turtle Mountains of North Dakota.

Environmental Description: This community is generally found along the upper slopes of river valley slopes, ravines, and moraine hills. In North Dakota, this community occurs on nearly level to hilly glacial till uplands along the edge of the Turtle Mountains. Slopes are commonly from 1 to 25%. Soils are deep, well-drained, medium- and moderately fine-textured soils. Permeability of these soils is moderately slow and available water capacity is high (Soil Conservation Service 1975).
Geographic Range: This community type is found in the north-central portion of the Great Plains of the United States and Canada, particularly in North Dakota and Manitoba.
