Narrow-leaved cattail (Typha angustifolia) and hybrid cattail (Typha x glauca) are aggressive invaders of wetlands in Wisconsin. Integrated Restorations, LLC, has been evaluating the use of the selectively-targeted herbicide imazapyr (Polaris) for reversing cattail invasions in species-rich fen and sedge meadow wetlands of the Mukwonago River watershed in southeastern Wisconsin. The treatment protocol they developed reduced cattail stem densities by more than 99% with remarkable improvements in native wetland vegetation species richness, diversity, and floristic quality. Join Integrated Restorations operations manager and principal restoration ecologist Craig Annen to hear more about the research and its results and learn how this approach may help you control invasive cattail in your wetland.
