The Isle Royale & Keweenaw Parks Association has sent us information saying:

Because of your interest in native plants, we wanted to let you know about a popular Botany Workshop (#9) in Isle Royale National Park this coming June and a second Botany Workshop to be held in September. A unique island national park located in western Lake Superior, Isle Royale is probably best-known for its wolf-moose study spanning more thanfive decades. However, this unique island is also home to a rich diversity of native plant species found in its many upland, wetland, and bedrock shoreline communities.  The details can be found here.
