Cattails and more cattails

DSC00084Last week we collected additional water chemistry, vegetation, measured biomass, velocity and discharge in our 2nd wetland located at the Lost Marsh just South Mankato. Navigating through the wetland was difficult due to the dense cattails that stood about 6ft above ground. The vegetation here was highly dominated by hybridized cattails which are a cross between narrow-leaved (introduced) and broad-leaved (native) cattails. The hybridized cattails can form mats and are extremely successful colonizers that can outcompete other native plants (including both broad-leaved and narrow-leaved), reducing biodiversity and changing nutrient uptake.
