The Creditview Wetland originated post de-glaciation ca. 12 000 b.p. It is now a small wetland pocket, approximately 5ha in size, located in the central part of Mississauga. A City of Mississauga property, it is one of the most urbanized of the wetland plots being monitored by the Terrestrial Monitoring Program.
Although it was once considered a bog community, it has slowly transitioned into an area with a diversity of wetland community types including willow thicket swamp, willow-buttonbush thicket swamp, cattail marshes and hawthorn thicket community. Historically, surrounding land-use was characterized by agriculture and successional old-field communities; however, it is now nestled in a subdivision of newly built Homes. Based on the landscape analysis for Credit River Watershed, the habitat patch within which the monitoring plot is nested scored 2/9, meaning it is part of a Supporting Ecofunction. However, the landscape analysis for the City of Mississauga scored it as 3/9, meaning from an urban perspective it is ranked as a Highly Supporting Ecofunction. These areas are important due to their size, diversity and/or location on the landscape and contribute to the ecological integrity of the Core patches.
Citizens under the leadership of Jocelyn Webber fought "The Battle of the Bog" to preserve the Creditview Wetland and subsequently the City of Mississauga purchased the Wetland back from developers in 1998. Urban development has encircled this natural wilderness over the past 17 years and there has been a significant decline in vegetation and in particular, wildlife species diversity and abundance. Being a self-contained basin perched above the water table, the Wetland is fed mostly by precipitation. Water quality and quantity influences and impacts significantly on the Wetland.
The Creditview Wetland is a unique feature in the city of Mississauga due to its designation as a Provincially Significant Wetland, its high diversity of plant species and vegetation communities, the presence of locally rare plants like buttonbush and its use by waterfowl as nesting grounds. This wetland also provides excellent educational and nature appreciation opportunities for local residents and students. Despite being surrounded almost entirely by urban land-use, the fence enclosing the wetland and the small buffer surrounding it assists in reducing dumping and unsanctioned trails, while the viewing platform still provides a means by which to appreciate the beauty of this community.
