Description:
This association comprises tall grassland vegetation of inland west-central Long Island, New York (Hempstead Plains). It is a unique association, the easternmost representative of midwestern prairies. It occurs on rolling outwash plains, sheltered from salt spray and offshore winds. Soils are loamy, well-drained, and shallow, lying over coarse outwash gravel of quartz and granite. Less than 30 acres, of what was formerly 38,000 acres, remain, and these are degraded. Historical dominants were midwestern tallgrass species such as Andropogon gerardii, Schizachyrium scoparium, Sorghastrum nutans, and Panicum virgatum, although these may now be sparse. Associates include Andropogon virginicus, Carex pensylvanica, Lespedeza capitata, Lespedeza hirta, Lespedeza angustifolia, Ionactis linariifolius (= Aster linariifolius), Solidago nemoralis, Solidago juncea, Hypoxis hirsuta, Baptisia tinctoria, Juncus greenei, Potentilla canadensis, Viola pedata, Viola sagittata var. ovata (= Viola fimbriatula), Eupatorium hyssopifolium, Asclepias tuberosa, and others. This association is similar in composition to Schizachyrium scoparium - Sorghastrum nutans - Andropogon gerardii - Lespedeza capitata Sand Herbaceous Vegetation (CEGL002210) but varies in the presence of coastal species Baptisia tinctoria, Juncus greenei, Ionactis linariifolius, and the absence of midwestern prairie associates Hesperostipa spartea (= Stipa spartea) and Lithospermum caroliniense.
