The relative importance values (number of quadrats in which they were found) of co-occurring species in low-density L. salicaria quadrats were significantly correlated with their relative importance in high-density L. salicaria quadrats, indicating that only modest shifts in abundance occurred as L. salicaria increased in density. In the wild it inhabits a range of damp habitats including river edges, marshes and pond margins. It was well-established in New England by the 1830s, and spread along canals and other waterways.

This article has tips on how to control this weed. However, it is still legally available for sale in some other states. It declined in some areas through habitat destruction and drainage, but it seeds readily and can quickly colonise new wetland sites. Volume 5. Biotic invasions: causes, epidemiology, consequences, and control. This highly invasive plant was likely introduced when its seeds were included in soil used as ballast in European sailing ships and discarded in North America. As it establishes and expands, it can out compete and replace native grasses, sedges, and other flowering plants that provide a higher quality source of nutrition for wildlife. Firstly, I should point out that an invasive species is different from an introduced species. Such conflicts surround the case of Lythrum salicaria (purple loosestrife), a widespread exotic wetland perennial.

Lythrum salicaria in pure, dense stands maintained a greater above-ground standing biomass on invaded sites than uninvaded vegetation of similar physiognomy. Purple loosestrife was probably introduced multiple times to North America, both as a contaminant in ship ballast and as an herbal remedy for dysentery, diarrhea, and other digestive ailments.
