Has the potential to retard natural succession. Because seeds can remain viable in soil for up to 10 years, and its ability to reproduce from rhizomes, quackgrass is extremely difficult to control mechanically. Buds are commonly held in a dormant state until separation from the parent plant occurs, so mechanical control efforts may only stimulate bud production. Roundup may be applied to actively growing quackgrass. Quackgrass may also be gradually replaced by other species through natural succession processes.
Notes Is a rapid invader, and quickly stabilizes moist eroding soils.
