Some of the pics shown are from typical Sault College Natural Environment and Outdoor Studies field trips around eastern Lake Superior in the Algoma District (Ontario) and the Upper Peninsula (Michigan), and as far east as Manitoulin Island in the northern portion of Lake Huron. There are also some pics of woody plants grown by myself and students in the Sault College greenhouse. The remaining pics stem from my botanical forays. |
