Location description
Large amount of emergent growth (Narrow leave/Hybrid Cattails), Off of busy 2 lane road, Marsh wetland, feeds buells creek which is a tributary to the St. Lawrence River, conservation area, frequented by water fowl I picked this area due to the large amount of housing construction going on about 200 meters away. the road going beside this location was also recently paved which makes me think the city will start to salt this road in the winter. as this location is both in a conservation area and a tributary to the St. Lawrence River it made sense to look into the salt contents
