Wetland

Provides a spatial representation and attribute information for wetlands in Ontario.

Wetlands are lands that are seasonally or permanently flooded by shallow water, as well as lands where the water table is close to or at the surface. In either case, the presence of abundant water has caused the formation of hydric (moist) soils and has favoured the dominance of either hydrophytic (water-loving) or water tolerant plants.     The term wetland is a general one and includes specific land types commonly called marshes, bogs, swamps and fens. Other terms sometimes used to describe wetlands include mires, sloughs and peatlands.     Periodically soaked or wetlands being used for agricultural purposes that no longer exhibit wetland characteristics are not considered to be wetlands for the purposes of this definition.     Wetland polygons are mapped independently from other hydrographic data classes and may overlap water bodies or other hydrographic data.     Not all wetlands have been identified and mapped. Active maintenance is ongoing province-wide.     Evaluators using the Ontario Wetland Evaluation System (OWES) will find additional guidance on the Ontario Wetlands evaluation page.   For user friendly viewing of the wetland data, navigate to Ontario’s Make a Natural Heritage Map web application. This map application displays wetlands that have been evaluated using the Ontario Wetland Evaluation System as provincially significant or non-provincially significant. The application also displays wetlands that have not been evaluated but have been mapped using other procedures.
