Description:
The shrubland vegetation of the Cook Mountain Calcareous Prairies consists of clumps or thickets of shrubs, most notably ~Crataegus$ spp. (~Crataegus spathulata, Crataegus crus-galli, Crataegus berberifolia$). Other dominant vines and shrubs include ~Berchemia scandens, Cornus drummondii, Diospyros virginiana, Juniperus virginiana var. virginiana, Ilex decidua, Sideroxylon lanuginosum ssp. lanuginosum, Prunus mexicana, Frangula caroliniana$, and ~Rubus$ spp. The tall-shrub stratum (2-5 m high) ranges from 25-60% cover. Open examples include a sparse to patchy ground cover. Grasses include ~Schizachyrium scoparium, Andropogon glomeratus, Andropogon gerardii, Sporobolus$ spp., ~Setaria parviflora, Panicum flexile, Aristida$ spp., ~Paspalum floridanum$, and ~Sorghastrum nutans$. This successional shrubland community develops on soils derived from marly clays and chalk of marine origin. These soils are typically silty clay loams, clays, and silt loams that are well-drained, slowly permeable, and alkaline (pH 7.5-8.0). Subsurface clay layers have calcareous concretions, weathered limestone aggregations, and shrink-swell properties. This community typically occupies 1-8 hectares within calcareous forests dominated by ~Pinus taeda$ or ~Quercus$ spp. This community occurs in a nearly level to gently rolling landscape, on ridgetops and on gentle slopes that often border small streams. Moisture regimes are typically dry to dry-mesic.
