In 2011, a field experiment was conducted to explore the restoration implications of removing invasive Typha x glauca biomass. Cut stems and dead leaf litter were removed from one set of replicate plots and belowground Typha rhizomes were removed from a second set. Read more about the Small Scale Cattail Harvest Study.
In 2015, we began the implementation of a scaled-up harvesting experiment to learn more about the long-term impact on plant community structure and Typha dominance. One focus is to examine how removing nitrogen and phosphorus from the wetland once they are bound in Typha leaf-tissue will help mitigate the effect of legacy nutrient pollution in the wetland.

Our lab has been investigating a suite of invasive plant species from the Chicago region to see whether they have the potential to be used as biofuel feedstock through either direct combustion or anaerobic digestion. Read more about the Invasives to Energy study.
Improving Connectivity in Typha-Invaded Great Lakes Coastal Wetlands
Having identified decreased aquatic connectivity and litter accumulation as two of the biggest degradation mechanisms resulting from invasion, we are investigating ways to improve the habitat value of a wetland without entirely removing invasive plants. Read more about the Improving Connectivity study.
In 2016, we began working on a Michigan DNR-funded project addressing frogbit management in cattail. European frogbit (Hydrocharis morsus-ranae) is a recently arrived invasive wetland plant in the Upper Great Lakes region. We have concluded that frogbit invasion can be facilitated by the presence of invasive cattails. Read more about the Frogbit Detection and Management study.
