Effects of harvesting invasive cattail (Typha x glauca) on methane flux in Great Lakes coastal wetlands

Project Overview

Project Abstract: 
Typha x glauca, or hybrid cattail, is an invasive species that has had significantly negative impacts on biodiversity in the Great Lakes region in particular. Many techniques have been used to inhibit invasive Typha growth including herbicide application and burning. While most Typha management strategies are focused on biodiversity, these strategies may also have significant impacts on other wetland ecosystem functions such as carbon cycling. The effect of repeated mechanical harvesting on carbon cyclingand methane flux over time in Typha invaded areas is not yet known. Field observations at Cheboygan Marsh, Michigan have indicated that the presence of floating mats of Typha appear more frequently in areas where repeated harvesting has occurred, potentially impacting methane emissions.
