A mesocosm experiment to test the effects of Typha x glauca invasion

Abstract: The results of the mesocosm experiment suggest that the effects of Typha x glauca invasion are due to two main mechanisms: out competition for resources and suppression of native plant growth by Typha litter accumulation. These data provide valuable information about the individual effects of each mechanism, allowing us to untangle confounding variables observed at Cheboygan Marsh. Fundamental changes to the soil environment have occurred at the marsh. Should action be taken to restore the marsh to its original native community, this research will provide valuable information as to the correct mode of action. Removing the invasive species is only the first step to restoration. In order to address the soil legacy, further action such as fire and removal of the nutrient-rich soil will be necessary. Further research will continue on the 15N pulse nutrient uptake experiment as well as annual stem counts on the mesocosms
