This new organism was introduced to a new habitat free from traditionalparasites, predators and competitors, purple loosestrife thrived in theenvironmental conditions and by 1880 was rapidly spreading north and westthrough the communication channel and marine routes.

With biological control we hind end only hope that the ecosystems can bebrought back under control.Purple loosestrife is a very serious problem. Its rapid invasion is threateningwetlands, water bird and fisheries as well as the novelty of Canadas flora andfauna. If this plant is non brought under control quickly then the result ofthis exotic species being brought to Canada could be disastrous. The use ofcultural and chemical control has not been effective so we now rely on thesuccess of biological control to stop the spread of this hardy invas ive plantand to replenish the diversity of Canadas wetland ecosystem. As a country wemust do everything we can to debase the spread and growth of purple loosestrife.As a concerned Canadian you can report any local purple loosestrife stands,spread your knowledge about the problem, strongly discourage the plantings ofany new plants or the merchandising of the weed in nurseries and join the OntarioFederation of Anglers and Hunters.
