Abstract

In early 2015, residents of Stella’s Landing Condos in Edmonds, WA noticed bittersweet nightshade, an invasive species, starting to encroach on their cattail-dominated wetland, known as Stella’s Marsh. In this investigative study, we will attempt to identify the potential changes that allowed the invasive bittersweet nightshade to proliferate in Stella’s Marsh by performing a Phase II Environmental Site Assessment. We will analyze water samples for metals and TPH-BTEX, and wetland sediments will be analyzed for metals and PAHs. Vegetation cover and distribution of the bittersweet nightshade and native cattail will also be measured. We aim to determine if there are any relationships between potential contamination in the wetland and the distribution of the bittersweet nightshade. Finally, we will suggest management strategies to address the invasive vegetation based on our findings.
