Name:
Crataegus spathulata - Cornus drummondii - Berchemia scandens Shrubland
Reference:
Southeastern Ecology Working Gro...
Description:
This shrubland is dominated by Crataegus spathulata, Crataegus crus-galli, Crataegus berberifolia, Crataegus engelmannii, 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. This community results from fire suppression of calcareous prairies but may also have occurred naturally in spatially or temporally fire-sheltered situations. It is associated with outcrops of the Cook Mountain Formation from western Winn Parish, west-central Louisiana and outcrops of the Fleming Formation in southeast Texas.
