Aquatic Plant Workshop

August 24 and 25

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.

The group also visited the Bete Grise sloughs.

GUIDE TO AQUATIC PLANTS: An aquatic plant handbook Guide to Aquatic Plants of Gratiot Lake and other Keweenaw County Lakes and accompanying CD was given to each participant and was used during the workshop.

MICHIGAN K-12 TEACHERS earned 12 SCECHS (State Continuing Education Clock Hours) by participating in this workshop.
