Roger Frymeier, Volunteer Extraordinaire
Roger Frymeier pauses from his task of removing invasive
aquatic plants called water chestnuts from Black's Nook. Roger patrols the pond in his kayak every spring to assure that the plants do not become reestablished. He is holding a stick that is covered with masses of aquatic animals called bryozoans, or moss animals. The translucent jelly-like blobs are colonies consisting of many individuals. When under water, each organism extends a featherlike organ that traps algae and funnels the food into its mouth.
