Aquatic Plant Research Ponds and Invasives

Concerned citizens from around the state reported that aquatic invasive plants were readily available in pet stores and garden stores despite regulations prohibiting the sale of certain species that had been in effect since 2009. In addition, populations of prohibited plants continued to be found in ponds and water gardens. This study looked at the relationship between retail sources of invasive plants and invasive plants on the landscape. Researchers found that the most common invasives in ponds are also the most common in the live plant trade, and that ponds with purple loosestrife are more likely closer to stores selling aquatics. Researchers also found that when considered together, regulated species in ponds are closer to stores selling regulated species. This work shows that there is a link between availability of invasive species and presence in ponds.
