Thirteen attendees of the aquatic plant workshop spent part of the weekend studying aquatic vegetation at Gratiot Lake. Participants improved their knowledge of aquatic plant identification and invasive species
Workshop activities took place both inside the classroom and in the field at several Keweenaw lakes and channels/coves connected to Lake Superior. Submersed and floating-leaved aquatic plants were identified with a focus on identification of pondweeds and rosette-formers including the Michigan endangered awlwort. Techniques for collecting and herbarium specimen/label preparation were demonstrated. Differences between aquatic invasive species such as Eurasian water-milfoil and curly-leaf pondweed and their native relatives were discussed.
