Effects of Phragmites australis Invasion on Carbon Dynamics in a Freshwater Marsh

Common reed (Phragmites australis) is an invasive grass that is altering wetlands in the Great Lakes region. To determine the effect of Phragmites invasion on wetland carbon (C) dynamics, we investigated environmental conditions, plant litter decomposition, and release of gaseous C from sediment pools in Phragmites-dominated and pre-invaded Typha stands in a coastal freshwater marsh.Common reed (Phragmites australis) is an invasive grass that is altering wetlands in the Great Lakes region.
