Description
T. flavus is a perennial graminoid of the Poaceae family native to North America and introduced to Canada.[2]
Distribution
T. flavus is found in the eastern half of the United States as well as California, and in the Ontario region of Canada. [2]
Ecology
Habitat
T. flavus proliferates in roadsides, disturbed areas, and glades.[1]
Specimens have been collected from drying loamy sands, burned pineland, bank of rivers, cypress swamp bank, open field, hammock, wooded floodplain, and pine-oak flatwood.[4]
Phenology
T. flavus has been observed to flower in October.[5]
Fire ecology
T. flavus is not fire resistant, but has high fire tolerance[2] as shown by populations that have been known to persist through repeated annual burning.[6][7]
Herbivory and toxicology
T. flavus has high palatability for grazing and browsing animals[2] , however the risk for cyanogenesis is present as cyanide has been detected in this species.[8] Cattle forage Tridens flavus in the summer and early fall, but the species can decrease under heavy grazing.[9]
