CEGL005072 Corylus americana - Salix humilis / Schizachyrium scoparium Sand Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: American Hazelnut - Prairie Willow / Little Bluestem Sand Shrubland

Colloquial Name: Hazelnut Sand Barrens

Hierarchy Level:  Association

Type Concept: This hazelnut sand barrens type is found in the tallgrass prairie-forest border region of Illinois and Indiana in the United States. Stands occur on dune slopes and sandy ridges of glacial lakeplains. The vegetation may contain scattered grubs of Quercus velutina and copses of Sassafras albidum interspersed with sand prairie or sand barrens vegetation. Dominant species in the shrub layer include Corylus americana and Salix humilis. Dominant herbaceous species include Schizachyrium scoparium and Sorghastrum nutans. Other characteristic species include Asclepias amplexicaulis, Lupinus perennis, Opuntia humifusa, Phlox bifida, and Staphylea trifolia. Open patches of sand may occur, and mosses and lichens may be common.

Classification Comments: This type is primarily known through historical records, and few stands remain today. This type may be expected on drier, finer-textured and sandy soils. There are serious classification difficulties in applying the concept of this type, as it falls between the black oak barrens type, ~Quercus velutina - Quercus ellipsoidalis - (Quercus alba) / Schizachyrium scoparium - Lupinus perennis Wooded Grassland (CEGL002492)$$, which can be quite scrubby, and open dry sand prairies, ~Schizachyrium scoparium - Danthonia spicata - Carex pensylvanica - (Viola pedata) Sand Grassland (CEGL002318)$$, or sand barrens, ~Schizachyrium scoparium - Carex muehlenbergii - Lithospermum caroliniense - Opuntia humifusa Sand Grassland (CEGL005099)$$. It remains to be determined how necessary a shrubby sand prairie or sand barrens category is. Type may occur in the Kankakee Sands area of Illinois. The type may also share some features with open shrub prairie types in ~Corylus americana - Malus ioensis - Ceanothus americanus Central Shrubland Alliance (A4208)$$, but those types are typically not as dry, nor on sand; thus overall floristics suggest leaving this association in with other sand prairies.

Floristics: The vegetation may contain scattered grubs of Quercus velutina and copses of Sassafras albidum interspersed with sand prairie or sand barrens vegetation. Dominant species in the shrub layer include Corylus americana and Salix humilis. Dominant herbaceous species include Schizachyrium scoparium and Sorghastrum nutans. Other characteristic species include Asclepias amplexicaulis, Lupinus perennis, Opuntia humifusa, Phlox bifida, and Staphylea trifolia. Open patches of sand may occur, and mosses and lichens may be common (Steffen and Anderson 1997).

Dynamics:  Droughts and fires interact to maintain the open, scrubby nature of this type (Steffen et al. 1997).

Environmental Description:  Stands occur on dune slopes and sandy ridges of glacial lakeplains.

Geographic Range: This type is found in the tallgrass prairie-forest border region of Illinois and Indiana in the United States.
