The Natural Areas Survey (NAS) is a study which identifies and inventories 140 natural areas within the City including woodlands, wetlands, creeks and streams. These areas comprise 7% of the total area of the City. The study also recommends strategies and guidelines for their future protection. Completed over a 3 year period, the study consists of 4 phases: review of existing reports and databases; survey of public opinion on environmental issues; site visits to 140 remnant natural areas; and development of databases for the natural areas. Each year one quadrant of the City is updated.
The guiding principle of the NAS is that the maintenance of the long term ecological integrity of remnant natural areas will generally have primacy over all other considerations, to the extent that is feasible. The natural areas will be protected through a systems approach that emphasizes the interdependence of remnant areas. A number of the recommendations of the Natural Areas Survey have been incorporated into the Official Plan for the City of Mississauga and is used by City staff when making decisions regarding the proper use of these areas.
