Name: Schizachyrium scoparium - Bouteloua spp. - Hesperostipa spartea Gravel Grassland Reference: NatureServe Biotics 2019 Description: This little bluestem gravel prairie community type is found in the northern tallgrass prairie region of the United States and possibly adjacent Canada. Stands occur on gently to steeply sloping sites on glacial outwash, glacial beaches, or other glacial features that have a high proportion of sand and gravel, such as kames and eskers. Soils are often Mollisols but not deep, and they contain fine to coarse gravel, sand, and often larger rocks. Soil moisture is typically low due to the well- to excessively drained nature of the soils. This community is a grassland dominated by midgrasses. Dominants are <i>Bouteloua curtipendula, Bouteloua gracilis, Schizachyrium scoparium</i>, and <i>Hesperostipa spartea</i>. Other common graminoids include <i>Andropogon gerardii, Bouteloua hirsuta, Calamovilfa longifolia, Carex inops ssp. heliophila, Sporobolus heterolepis</i>, and <i>Hesperostipa comata</i>. Forb diversity is moderate to high. Typical examples include <i>Artemisia frigida, Astragalus laxmannii var. robustior, Echinacea angustifolia, Lygodesmia juncea, Potentilla pensylvanica</i>, and <i>Solidago missouriensis</i>. Shrubs are absent to widely scattered. Those present may include <i>Amorpha canescens, Rosa arkansana</i>, and <i>Symphoricarpos occidentalis</i>. Lichens and mosses often occur on bare soil and gravel.  Accession Code: urn:lsid:vegbank.org:commConcept:31407-{0FCCB97F-2194-4AAC-89F2-6E861E033172} Plot-observations of this Community Concept: 0
