Sixteen Mile Creek Ecological Restoration Master Plan

The new Boyne community, home to 50,000 residents, triggered the development of an Ecological Restoration Master Plan to protect and enhance the Sixteen Mile Creek valley, the largest natural feature identified in the planned Natural Heritage System (NHS). This significant and important feature is a diverse and extensive system of natural and cultural vegetation cover types. Though disturbed by over a century of farming, it is still known as one of the top botanical sites in the region.

Environmental Impact Assessment Guideline Development & Training

The Province of Ontario retained T. Hilditch to lead the development of Environmental Impact Assessment (EIA) Guidelines for use by various stakeholders to assess potential effects associated with pro- posed developments, on adjacent natural features.
