About
Located on St. Joseph Island along the St. Mary’s River, the 42-hectare (103-acre) Hay Marsh Nature Reserve protects a precious piece of Great Lakes shoreline. The nature reserve is part of the Hay Marsh wetland, an important provincially significant coastal wetland composed of a diverse system of fen, rich conifer swamps, raised beach ridges, low dunes and swales and dramatic sweeping vistas of coastal marsh.
The property donor, John Kerastas, enjoyed many summers fishing and hiking in northern Ontario’s bush, and wanted to see Hay Marsh protected. “Just as I enjoyed the Canadian wilderness,” says Kerastas, “so too should future generations have that privilege.”
Plants and Animals
Ontario Nature’s Hay Marsh Nature Reserve is composed primarily of mixed swamp with a marsh along the shoreline of the St. Mary’s River. In the fall, the tamarack trees blaze in golden hues, while the black ash, sugar maple and poplar trees complete the autumn colour spectrum.
Shallow marshes of cattail and thickets of alder and bulrush extend along the river’s edge. The nature reserve is an important stopover for migrating waterfowl, as well as a fine habitat for spawning fish.
Visiting
Hay Marsh Nature Reserve is virtually inaccessible by land, and it is difficult to land a boat on the shoreline. To protect this nature reserve, this property does not have a marked trail system and is not open to members of the public. Please contact Ontario Nature if you are interested in conducting research or learning more about this property.
Stewardship
The Sault Naturalists’ Club are the official stewards of this property. Their stewardship has been integral to furthering protection of sensitive habitat on the property.
