Japanses Knotweed & the Arboretum
Japanese Knotweed is the most detrimental invader in the Frostburg State University arboretum. In a few short years, it has managed to colonize almost the entire riparian area in the arboretum and has subsequently choked out several native plant species.
Currently, the Allen HallSTARS!, the Biology Department, The Wildlife Society, and other students, faculty, and staff have been working together to remove this invasive plant. Efforts to rid the arboretum have included cutting and burning the stalks, using shade cloth to inhibit growth, and dripping herbicide into cut stems. Since it is an intense nutrient competitor and has an extensive rhizome system, knotweed can withstand many treatments.
Our goals are to eventually "starve" out the root systems in order to kill the plants. Complete eradication of the knotweed may not be possible, but hopefully it will be kept under control.
