Manitoulin Geology, People, and Plants Andy Fyon, Ontario Geological Survey, Sudbury, Ontario, Canada Friends of Misery Bay, Manitoulin Island, August 14, 2011

PowerPoint Presentation:

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.

Learning Outcomes:

Learning Outcomes Learn something about geology + geological processes. Learn something about relationship between geology, people and plants. Relate plants and (geological) habitat. Facebook (OGSgeology / Andy.wildflower)

PowerPoint Presentation:

If the Power Goes Out…Please Remember This Manitoulin Island Alvar Manitoulin Gold ( Hymenoxys herbacea ) Geological features influence types and distribution of plant communities BUT Geology is not the only factor
