A Guide to the Geology & Landforms of Grey & Bruce Counties
The aim of this book is to present an over-view of this subject that will be intelligible to anyone interested in this unique area. Geological formations are described first, followed by glaciation and landforms resulting from the ice age. Lake features are outlined and there is a chapter on karst formations, followed by an outline of post-glacial formations created by wind and river action.
Grey and Bruce counties are in an unusual position in Ontario, sandwiched between Lake Huron and Georgian Bay, dominated by the Niagara Escarpment and the tilt of the Michigan Basin. There are many Areas of Natural and Scientific Interest (ANSI’s) related specifically to Geology. A Geology and Landform site map with ANSI locations is included. There is also a map of the Physiography and a third of Bedrock Geology. In the appendices, locations are identified where specific features can be viewed

A Checklist of Vascular Plants for Bruce & Grey Counties
This is the definitive checklist of vascular plants for Bruce and Grey counties listing 1447 taxa (species, subspecies and hybrids) for 136 families, including 72 provincially rare. It is the only publication identifying all locally rare plants in Bruce and Grey counties, as well as provincially rare.The two counties have been divided into three zones: Bruce Peninsula(p), Southern Bruce(b), and Grey County(g). Species presence in those zones is noted by the letters pbg in a superscript. Upper case PBG indicates very uncommon, and bolded upper case PBG indicates local rarity. Marginal symbols indicate the following categories: naturalized – non- native in Ontario; naturalized but native in Ontario; cultivation escapes; provincially rare in Ontario (NHIC); historical record.
This is an essential reference for botanists, life science inventory specialists, land use planners, resource management agencies, and consultants that are working on projects within Bruce and Grey counties.
