In legacy NPSpecies Weedy value was Yes In legacy NPSpecies Pest value was Yes with comment: TNEPPC RANK=SEVERE THREAT; I-Rank=High/medium; Microstegium vimineum is established in most eastern states; it occurs from New York to Illinois south to Florida and Texas. M. vimineum is slow to invade undisturbed vegetation but spreads quickly and forms dense monocultures in areas with natural or human-caused disturbance. Its habitats include stream banks, river bluffs, floodplains, emergent and forested wetlands, moist woodlands and forests, early successional fields, woodland thickets, and rights-of-way. M. vimineum grows very well under low light conditions such as under a forest canopy. M. vimineum can displace native vegetation in a few years and also impacts ground nesting birds. M. vimineum may also impact ecosystems by altering soil conditions. M. vimineum produces 100-1000 seeds per plant. Seeds remain viable in the soil for at least 3-5 years. Once established, the removal of M. vimineum requires major eradication and restoration efforts. (NatureServe 2007).
