Final Report of the Natural Areas inventory of the Regional Municipality of Halimand-Norfolk 1985-86. (Site must satisfy two or more of the selection criteria to be classified as a “Significant Natural Area”; alternatively, an area could be classified as a “Significant Site” if the Significant Species criterion was satisfied in an outstanding way, or if the site provided critical habitat for aggregations of species that are not necessarily considered rare, ex. a heron rookery). 2Heagy, A., Hattie, B. 1995.

Areas which fulfilled one or two criteria were called Significant Sites). 3Geomatics International Inc. 1996. City of Mississauga Natural Areas Inventory. (Area needs
