Draft report submitted to the National Park Service, Appalachian Highlands I&M Network, Asheville, NC. Legacy NPSpecies information may no longer be applicable, please remove if it is not applicable. In legacy NPSpecies Weedy value was Yes In legacy NPSpecies Pest value was Yes with comment: TNEPPC RANK=SEVERE THREAT; I-Rank=High; This extremely invasive species has the potential to completely dominate a wetland setting, forming a vast, monotypic stand. It can crowd out, outcomplete, and completely eliminate native species and aquatic plant layers and suppresses and eliminates native plants and seed growth. It can potentially hybridize with native loosestrife, which is considered rare in some states. The species is very widespread in the U.S. occurring almost everywhere and is considered invasive in most states. Seeds are easily and widely dispersed by water and the plant is extremely prolific, even in undisturbed areas. Eradication is possible for early infestations but is often costly and time consuming with millions of dollars being spent annually on removal of this species in the U.S.(NatureServe 2007).
