Purple loosestrife is an invader of wetland and riparian habitats. Its tall spike of purple flowers makes it an easily recognizable plant. Some purple loosestrife has been indentified within the CWMA region, but we are always looking for more reports. Mid-tolate summer is the best time to identify purple loosestrife because the flowers are present. If you out in a boat this summer keep a lookout for this invasive plant and be sure to report any suspected infestations to us at www.rtrcwma.org/report/. For more information on purple loosestrife see: http://www.invasive.org/weedus/subject.html?sub=3047.
The River to River Cooperative Weed Management Area is a partnership between 12 federal and state agencies, organizations, and universities aimed at coordinating efforts and programs for addressing the threat of invasive plants in Southern Illinois.
