I found Invasive Phragmites by the artificial pond on St. Lawrence University's campus. Invasive Phragmites is a tall terrestrial plant that usually grows in clusters near marshes. It can be identified from native phragmites by its height, and the color of its stem base. This invasive phragmites was found during the spring and is a tan color with a seed/flowering head. Being that it is spring, most of the phragmites plants were knocked over and dead with the exception of these few phragmites stems.
