Ecology
Habitat
In the Southeastern Region, Digitaria filiformis is found in pine-oak, oak-palmetto and open longleaf pine-wiregrass woodlands along with turkey-oak sand ridges, banks of ditches in saltmarshes, and transition zones between longleaf pine, turkey oak sand ridge and pine flatwoods (FSU Herbarium).It has been documented as occurring on “upland, sandhill areas on droughty, infertile entisols and ultisols with loamy sand to sandy loam surface horizons” (Archer et al. 2007). Occasionally has been found in mesic flatwoods in Hillsborough County, Florida (Myers et al. 2003). It has been vouchered in an outcrop habitat on Panola Mountain located within Henry-Rockdale county line, southeast of Atlanta, Georgia (Bostick 1971). D.filiformis also occurs in the Kansas-Nebraska Drift Loess Hills characterized by divides with moderately steep slopes and silt loams and silty clay loam soils occasionally broken by bedrock outcrops (Watt et al. 1967).
Human impacted areas such as fallow and open weedy park fields, roadsides, powerline corridors, clobbered longleaf pine forest and cleared sand pine and pine flatwood communities show populations of D. filiformis (FSU Herbarium).
Soil types recorded are dry loamy sand and silty soils (FSU Herbarium). Light levels have observed to be partially shaded (FSU Herbarium).
Species found associated are Liatris, Pityopsis, Aristida stricta, Aristida purpurascens, Andropogon gerardii, Pteridium aquilinum, Nolina atopocarpa, Hedeoma graveolens, Hedyotis procumbens, Angelica dentata, Rhynchospora globularis, Solidago and Eragrostis(FSU Herbarium).
Phenology
Flowering and fruiting have been observed in June, August, September, October and November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species has been found in habitat types that are maintained by fire, which implies some level of fire tolerance (FSU Herbarium).
Pollination
Use by animals
White-tailed deer stomach contents, in Kansas-Nebraska Drift Loess Hills, included Digitaria filiformis year-round (Watt et al. 1967).
