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.

Craig Annen earned his bachelor’s of science in environmental science and plant molecular cell biology from Edgewood College in 1998 and his master’s of science in aquatic botany from the UW-LaCrosse in 2001. His research interests include invasive species management, economical ecology, and mathematical ecology. Craig is senior ecologist and operations manager of the firm Integrated Restorations, LLC. He speaks fluent German, is a New York Yankees fan, and is a gourmet cook of Middle Eastern and German cuisine.
