Botanist Janet Marr taught a GLC sponsored Aquatic Plant Workshop on August 18th and 19th.
Workshop activities took place both inside the classroom and in the field at Gratiot Lake and the Bete Grise Preserve. 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.
