Estimating wetland conversion as an indicator of relative habitat loss (ht/ht-1) Wetland conversion has been estimated between four time periods (~, , , ) for geographic townships corresponding to the Mixwood Plains Ecozone (Lake Simcoe-Rideau and Lake Erie-Lake Ontario Ecoregions) and presented in the Southern Ontario Wetland Conversion Analysis Final . Wetlands serve critical ecological functions, such as water retention, flood prevention, improved water quality, ground water recharge, and shelter, water and forage for wild life. They provide valuable economic products and recreational opportunities Southern Ontario experienced a historic conversion of wetlands to agricultural land uses. In
Between and , a total of 6, ha of wetlands were lost representing % of the wetland area in southern Ontario. The rate of wetland loss over this decade ( ha per year) is considerably less than the rate of 3, ha per year over the previous year period.

The status of wetlands in southern Ontario. wetland distribution, conversion of the landscape to agriculture represents a dominant type of land cover disturbance and Southern Ontario, Author: Michal Bardecki. Wetlands range in size from very small (the size of an urban backyard) to exceptionally large, covering hundreds of square kilometres.
There are four types of wetland in Ontario: marsh, swamp, bog, and fen. Bogs and fens contain peat (partially decomposed plant material) and. -Ontario Wetland Evaluation System - Southern Manual (13 MB) There are two OWES manuals, one for southern Ontario and one for northern Ontario.
The manuals are reviewed periodically to incorporate new science, technology and information. The OWES was created in. The Issue. Wetlands are diverse and delicate ecosystems that are both ecologically and economically valuable.
Despite this, less than 30 percent of our original wetlands remain in southern Ontario. In the Niagara and Greater Toronto Area, that number drops to 10 percent. Many factors contribute to wetland loss. Wetland distribution and conversion in Southern Ontario.

Even with the historic loss of wetland in much of southern Ontario, there remains a relatively high concentration of wetland area around Mississippi Lake. The Lake lies on the transition zone between the Canadian Shield on the west side, and the limestone plains of the Champlain Sea on the east side, occupying a stretch of the Mississippi River that would have originally been dominated by wetlands.
As wetlands such as marshes and bogs continue to disappear in southern Ontario, LPRCA’s efforts are helping to revive these important habitats for animals and native vegetation.
OPG, through its Regional Biodiversity Program, helps fund the conservation authority’s tree planting and wetland restoration initiatives. The majority of Ontario’s human population resides in southern Ontario, and this settlement pattern has been a major factor contributing to wetland loss in the province.
Marsh, Darryl Mitchell. Wetlands are continually under stress from both naturally occurring phenomena and human disturbances. Some stress is beneficial for wetlands. This finding was confirmed by Spaling (), who concluded that drainage contributed to a decrease in total wetland area, average patch size, and distribution of wetlands.
Agricultural drainage has accounted for between 81 and 85% of wetland losses in southern Ontario Cited by: Snell EA () Wetland distribution and conversion in southern Ontario, Working paper No.
