Ecology
Habitat
Lespedeza angustifolia habitats include sandhills, pine flatwoods, and oldfield pinelands, as well as dry pond margins and open flood plains on areas that are mesic to excessively well drained (FSU Herbarium). It has been strongly associated with hydric habitats (Hainds et al. 1990) because of a higher tolerance for periodically inundated soil conditions (Hainds et al. 1997). It has been documented to occur in dried up bottoms of sinkhole ponds (FSU Herbarium). Soils include sand and sandy loams, including Ultisols, Entisols, and dry Spodosols .[1]. Other soil types includes red sandy clay hills and sandy peat (FSU Herbarium).
L. angustifolia is prevalent along eroded roadsides and railroads and in disturbed high pine habitats (FSU Herbarium).
Plants associated include Aristida, Ctenium, Andropogon, Sporobolus and Panicum hemitomon (FSU Herbarium).
Phenology
Blooms September to November (FSU Herbarium). Frequent where present by populations tend to be separated from one another.[2]
Seed dispersal
Seed bank and germination
Lespedeza and other legume species have a hard seed coat. Species with hard seed coats are likely capable of forming long-term persistent seed banks and continuation of the buried seed bag portion of this study will yield long-term data on this subject (Coffey and Kirkman 2006). Although perennial species found in longleaf pine ecosystems, such as Lespedeza, persist through frequent fire, fire exposes seeds in soil to higher temperature and high amplitudes of temperature fluctuation (Grime 1989) leading in some cases to germination (Coffey and Kirkman 2006).
Fire ecology
Frequent dormant season burning increased legume populations in southern pine forests, although fires during the growing season at the same frequency tended to reduce legume abundance (White et. al 1990).
Presence of Imperata cylindrica (cogan grass), an invasive plant found in the southeastern United States, did not deter the occurrence of L. angustifolia in plots that had been burned every 1 to 2 years in southeastern Mississippi (Brewer and Cralle 2003). In its natural habitat it requires frequent fire for persistence. It is primarily located in undisturbed sites and sometimes colonizes frequently burned old-field pinelands.[2]
