Purple Loosestrife, or Lythrum salicaria to give it its botanical name, is a native perennial, widespread across the UK. University of Georgia. Purportedly sterile cultivars, with many flower colors, are still sold by nurseries. In the wild it inhabits a range of damp habitats including river edges, marshes and pond margins. Purple loosestrife (Lythrum salicaria) is a woody half-shrub, wetland perennial that has the ability to out-compete most native species in BC’s wetland ecosystems.Dense stands of purple loosestrife threaten plant and animal diversity. 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. 382-390.

Species richness, other diversity metrics, and stem density of other species were not significantly correlated with the density or percent cover of L. salicaria stems. 1999. This is an introduced species, all the way from Uruguay. This study demonstrates that hypotheses about L. salicaria effects can vary depending upon the ecological metric that is examined. General biology, distribution and germination. Oikos 79:26–33. Growing in dense thickets, loosestrife crowds out native plants that wildlife use for food, nesting, and hiding places, while having little or no value for wildlife itself. In the wild, Purple-loosestrife can be found like a garland along the margins of rivers, canals, ponds and lakes, and often grows scattered through damp fens and marshes. It invades wetland habitats, marshes, riparian areas, and natural areas, and it outcompetes native wetland vegetation.

We explored linear and non-linear relationships of above-ground plant biomass, stem density, and indices of species richness, diversity, and composition to gradients of L. salicaria dominance, including stem density, percent cover, and biomass. Instead, place them in the municipal green waste, as this is composted on an industrial scale, where tough weeds should be killed off. YouTube; Vermont Agency of Natural Resources. Marshes, river and creek banks, ditches and wet meadows. Between July 1998, and July 1999, the amount of purple loosestrife around the boat ramp at Pleasant Lake in St. Joseph county decreased dramatically. Wetlands Where one-time, correlative studies are the most feasible option, data taken on a range of metrics—especially biomass—should be taken to inform us about mechanisms by which L. salicaria invades and predominates in wetlands.

Description: Purple loosestrife is a non-native herbaceous perennial with a stiff, four-sided stem and snowy spikes of numerous magenta flowers.Individual flowers have five to seven petals, and are attached close to the stem. Addressing Purple Loosestrife management in Rhode Island. Releasing the insects that control loosestrife in Europe can bring it under control. It tolerates a wide variety of moisture, nutrient, and pH conditions. Purple loosestrife has become such a pest because it came to North America without the insects that control it where it is native. Geotoxi Associates, Inc. 1995.

This lovely wildflower is widespread throughout the UK and Ireland and is also found in most other mainland European countries, including Slovenia. While not a threat to most terrestrial crop systems, purple loosestrife has affected the production of wild hay and wild rice, primarily in mid-Western prairie pothole wetlands. Ecology 77:259–270. So you get to Canada, and inevitably some seeds slip out somewhere, you plant a couple plants, and eventually, it’s in the natural environment. Firstly, I should point out that an invasive species is different from an introduced species. Pielou, E. C. 1975. The leaves attach to its stem in an alternating pattern.

Purple loosestrife is a very hardy perennial which can rapidly degrade wetlands, diminishing their value for wildlife habitat. 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.
