Description
Distribution
Ecology
D. dichotomum was among the species that responded positively to reduction of woody vegetation using triclopyr herbicide[1].
Habitat
It can live in wet areas[2]. Dichanthelium dichotomum var. dichotomum can be found in disturbed sites[3].Dichanthelium dichotomum var. ensifolium can live in wet pine savannas[2]. It can also be found in longleaf pine communities[4], loblolly pine communities[1], and flatwoods communities [5].
Phenology
Seed dispersal
Dichanthelium dichotomum was common in the seed bank of a Florida flatwoods community[5] Dichanthelium dichotomum var. nitidum was found in the seed bank of both disturbed and undisturbed sites[3]
Seed bank and germination
From observing the results of Taft's prescribed burns, fire seems to be required for germination[6].
Fire ecology
It is fire-tolerant[2] Following an early, moderate-intensity dormant-season burn (November) in a dry sandstone barrens, D. dichotomum increased rapidly, probably as a result of the widespread stimulation of the seed bank. It was still observed on site six years after the burn[6].
