Description
Distribution
Ecology
Habitat
Kaczor and Hartnett found that T. dichotomum had signifcantly lower cover on old tortoise mounds and undisturbed plots (1990). Found in the longleaf pine patches that surrounded the golf course in Haile Plantation, Gainesville, Florida.
Phenology
Seed dispersal
Seed bank and germination
High light intensities and large diurnal temperature fluctuations as a result of the tortoise mounds are probably favorable for the establishment of T. dichotomum (Bazzaz 1979 cited by Kaczor and Hartnett 1990).
Fire ecology
Pollination
Mark Deyrup at Archbold Biological Station observed these Hymenoptera species on Trichostema dichotomum
Halictidae: Lasioglossum placidensis
Use by animals
It was found to be one of the most common spring recruits on recently abandoned tortoise mounds (Kaczor and Hartnett 1990). Deyrup (2012) observed the bees, Caupolicana electa and Dialictus placidensis, on T. dichotomum.
