Matchedash Bay is a bay and Ramsar wetland in Simcoe County in Central Ontario, Canada. [2] [3] It is the "final inland extension of Severn Sound" [4] on Lake Huron's Georgian Bay, and is "situated at the interface between the Saint Lawrence Lowlands and the Canadian Shield ". [5] It exhibits geologically unique features at the junction of the Canadian Shield and southern Ontario limestone. Wetland habitats in Matchedash Bay are varied, and include swamps, fens, cattail marshes, wet meadows and beaver ponds. [6] Other features include "permanent freshwater lakes; upland hardwood forest, agricultural lands, native grass meadows and a unique, coniferous wetland forest". [6]

A great diversity of species are indigenous to Matchedash Bay, including over 550 species of vascular plants, 34 species of fish, 28 species of mammal and 17 species of reptiles and amphibian, and it supports "one of the greatest diversities of herpeto fauna in Canada". [5] Of the 170 species of birds that nest or breed in Matchedash Bay, some are provincially rare. [6] It is also an important spring and autumn migratory staging area in the province.

Water levels in Matchedash Bay fluctuate constantly in tandem with Lake Huron and the tributary North River and Coldwater River. [4] [5] These water level fluctuations are a natural part of the ecology of Great Lakes wetlands, and are necessary for maintaining the area and diversity of this wetland. [7] [8]

Ducks Unlimited has purchased small portions of the site, for example an 18-hectare (44-acre) purchase in 1996, "to ensure permanent protection" of the area. [9] However, Matchedash Bay is a popular recreational area with cottages and marinas. Urban growth in the surrounding areas is expected to negatively affect the site and its water quality. [6]

Littoral zone Part of a sea, lake or river that is close to the shore

The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. The littoral zone always includes this intertidal zone, and the terms are often used interchangeably. However, the meaning of littoral zone can extend well beyond the intertidal zone.

Shiawassee National Wildlife Refuge

The Shiawassee National Wildlife Refuge is a 9,870.35 acres (39.9439 km2) National Wildlife Refuge in Saginaw County managed by the United States Fish and Wildlife Service. It is located in the central portion of the lower peninsula of the U.S. state of Michigan, approximately 25 miles (40 km) south of the Saginaw Bay in Lake Huron and five miles (8 km) south of the city of Saginaw in the county's Spaulding and James townships. It was established in 1953 to provide habitat for migratory waterfowl.

A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention. The Convention on Wetlands, known as the Ramsar Convention, is an intergovernmental environmental treaty established in 1971 by UNESCO, which came into force in 1975. It provides for national action and international cooperation regarding the conservation of wetlands, and wise sustainable use of their resources. Ramsar identifies wetlands of international importance, especially those providing waterfowl habitat.

Presquile Provincial Park

Presqu'ile Provincial Park is a park in southeastern Northumberland County on the north shore of Lake Ontario near the town of Brighton in Ontario, Canada. The park occupies an area of 9.37 km2 (3.62 sq mi). The name of the park is the French word for peninsula, or literally "almost island", and was believed to be named by Samuel De Champlain on his second expedition. The peninsula was formed when a limestone island was connected to the mainland by a sand spit; this kind of formation is referred to as a tombolo.

Peace–Athabasca Delta

The Peace–Athabasca Delta, located in northeast Alberta, is the largest freshwater inland river delta in North America. It is located partially within the southeast corner of Wood Buffalo National Park, Canada's largest national park, and also spreads into the Regional Municipality of Wood Buffalo, west and south of the historical community of Fort Chipewyan. The delta encompasses approximately 321,200 ha, formed where the Peace and Athabasca rivers converge on the Slave River and Lake Athabasca. The delta region is designated a wetland of international importance and a UNESCO World Heritage Site. The region is large enough that it is considered one of twenty distinct natural subregions of Alberta by the provincial government's Natural Regions Committee.

Wet meadow type of wetland

A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes.

Pond A relatively small body of standing water


A pond is an area filled with water, either natural or artificial, that is smaller than a lake. It may arise naturally in floodplains as part of a river system, or be a somewhat isolated depression. It may contain shallow water with aquatic plants and animals.

Mixedwood Plains Ecozone (Canada) Canadian ecozone with the most southerly extent

The Mixedwood Plains Ecozone is the Canadian ecozone with the most southern extent, covering all of southwestern Ontario, and parts of central and northeastern Ontario and southern Quebec along the Saint Lawrence River. It was originally dominated by temperate deciduous forest growing mostly on limestone covered by glacial till. It is the smallest ecozone in Canada, but it includes the country's most productive industrial and commercial region, and is home to nearly half of Canada's population, including its two largest cities, Toronto, Ontario and Montreal, Quebec. Hence, little of the original forest cover remains, making protection of the remaining forests a high conservation priority. This ecozone includes two regions described by J.S. Rowe in his classic Forest Regions of Canada: the entire Deciduous Forest Region, and the southern portions of the Great Lakes-St. Lawrence Forest Region. In the province of Ontario, the Ontario Ministry of Natural Resources maps this area as Site Regions 6E and 7E.

Scotch Corners Wetland

Scotch Corners Wetland is a provincially significant wetland complex located in Lanark County, Ontario, Canada. The 202 hectares area has a wide array of wetland types including swamps, marshes, vernal pools, beaver ponds and seepage areas. It forms the headwaters of several creeks that drain into Mississippi Lake.
