How Do Management Treatments Affect Invasive Cattail (Typha X Glauca) And Pore Water Nutrient Concentrations?, Yarency Rodriguez
How Do Management Treatments Affect Invasive Cattail (Typha X Glauca) And Pore Water Nutrient Concentrations?, Yarency Rodriguez
DePaul Discoveries
Invasive species are problematic for wetland managers, but little is known about how common management treatments influence nutrient cycling or plant responses. This study tested three experimental treatments (mowing, herbiciding, and harvesting (i.e., removal of aboveground biomass)) on several response variables: wetland soil porewater nutrient content (NO3-, NH4+, PO4-), native plant and invasive-Typha density, and light attenuation through the plant canopy. Seventeen days post-treatment, herbiciding resulted in higher porewater phosphate concentrations (55.63 µg-P/L) than harvesting (8.95 µg-P/L). After 24 days, herbicide had higher porewater phosphate concentration (72.03 µg-P/L) than all …
