1 Manitoulin Geology, People, and Plants Friends of Misery Bay, Manitoulin Island, August 14, 2011 Andy Fyon, Ontario Geological Survey, Sudbury, Ontario, Canada
2 Not horticulturist or biologist. Not expert on alvar flora. Flowering plants: hobby Prefer not to discuss medicinal or culinary uses of plants Tell a Story Don't have all the answers. Lots of questions try together.
3 If the Power Goes Out Please Remember This Geological features influence types and distribution of plant communities BUT Geology is not the only factor Manitoulin Island Alvar Manitoulin Gold (Hymenoxys herbacea)
