Description
Distribution
Ecology
Habitat
This species occurs in an extremely wide range of open habitat conditions, including frequently burned longleaf pine and shortleaf pine-oak-hickory communities (Elliott et al 2005), longleaf pine and pine-turkey oak sandhills, Florida scrub communities, pine flatwoods, wet savannas, wet depressions within pinelands, seepage slopes (pitcher plant bogs), calcareous (rockland) slash pine flatwoods, dune swales, shrubby wet prairies, and open cypress swamps (Haywood 2012; FSU Herbarium). Soil conditions include deep sand Entisols, sandy loam Ultisols, sandy peat Spodosols, wet Histosols (peat).
Phenology
Seed dispersal
Seed bank and germination
In sandhill communities, it suffers from seed germination and radical growth inhibition by allelopathic scrub species during the beginning of the rainy season (Richardson 1985; Richardson and Williamson 1988).
Fire ecology
Elliott and Vose initiated a single dormant season burn (low to moderate intensity fire) on a plot containing Andropogon gyrans to see if it would stimulate growth. Additional burning may be required to stimulate its growth and the growth of other bluestem-grasses (Elliott et al 2005). Prescribed fire and pine straw harvesting both led to increases in herbaceous plant production (including A. gyrans) (Haywood 2012). It is most common in native communities with minimal soil disturbance. A. gyrans was among the species that responded positively to reduction of woody vegetation using triclopyr herbicide (Miller et al. 1999).
