CEGL002162 Quercus macrocarpa / Mixedgrass Sand Wooded Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bur Oak / Mixedgrass Sand Wooded Grassland
Colloquial Name: Great Plains Bur Oak / Mixedgrass Sand Wooded Grassland
Hierarchy Level: Association
Type Concept: This bur oak sand savanna is found in the northern Great Plains of the United States and Canada. Stands occur on sandy lacustrine and glacial outwash deposits reworked by wind. Soils are infertile, sandy, and excessively well-drained. This community has a canopy consisting of open grown trees, predominantly Quercus macrocarpa. The understory is made up of graminoids and forbs with scattered shrubs. Common constituents of the understory include Andropogon gerardii, Hesperostipa spartea, Carex pensylvanica, and Corylus spp.

Classification Comments: This type is very poorly understood. Its range is west of the tallgrass prairie region, where the oak barrens, ~Quercus macrocarpa - (Quercus ellipsoidalis) / Schizachyrium scoparium - Koeleria macrantha Wooded Grassland (CEGL002160)$$, are found. Key understory indicators are needed to distinguish the two types. In North Dakota, these oak savannas are mainly on the sandy outwash of the Souris Lake Plain (D. Lenz pers. comm. 1997). On the Sheyenne Delta, the main type is the oak barrens type (CEGL002160), though stands there may also resemble this type.
