Saint Clair National Wildlife Area (NWA) is located 19 kilometers (km) west of Chatham, Ontario. It lies within the extensive marsh habitat that spreads from Mitchell's Bay to the mouth of the Thames River, along the southeast shore of Lake Saint Clair.

Description

Originally established in 1978, the NWA is comprised of two properties: Saint Clair (244 hectares (ha)) and Bear Creek (113 ha). This area is dominated by wetland habitat, with remnant patches of tall-grass prairie. Saint Clair NWA is also listed as a Ramsar wetland, an International Butterfly Reserve, and part of the Eastern Lake St. Clair Important Bird Area (IBA).

St. Clair National Wildlife Area

Lake St. Clair and adjacent marshes are the most important staging area for waterfowl in Ontario, south of James Bay. The wetlands consist mainly of cattail marsh encircled by constructed dykes that mimic natural water-level changes. This area is located at the transition between two major migratory routes: the Atlantic and Mississippi flyways.

Every year during migration, hundreds of thousands of waterfowl, including the tundra swan, pass through this NWA. Puddle ducks, geese and diving ducks also use this habitat as a staging area every year during migration.

This area provides important habitat for both common and rare marsh birds, reptiles, amphibians, mammals and rare prairie plants.

The St. Clair NWA provides habitat to 20 species at risk (endangered, threatened, and special concern), ranging from birds, mammals, fish, insects, reptiles and plants. Some examples of species at risk include:

  • least bittern
  • king rail
  • pugnose shiner
  • monarch
  • queen snake
  • eastern foxsnake
  • swamp rose mallow

More information on the Saint Clair NWA can be found in the summary table below.

Management

Under the Canada Wildlife Act, NWAs are protected and managed in accordance with the Wildlife Area Regulations. The primary purpose of NWAs is to protect and conserve wildlife and their habitat. For this purpose and according to the legislation, all activities in a NWA that could interfere with the conservation of wildlife can be prohibited. Consequently, most NWAs are not accessible to the public and all activities are prohibited. However, some activities may be authorized through public notice or the issuance of permits as long as they are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.

Access to some portions of the St. Clair NWA is restricted to protect wildlife and their habitats from disturbance. Some activities are permitted in accordance with the conservation goals of the NWA management plan. Public notices listing the authorized activities are posted at access points. Fishing and recreational boating are prohibited within the St. Clair unit, where the following activities are limited to designated areas and for day use only:

  • hiking trail
  • wildlife viewing tower

Within the Bear Creek Unit, public access is prohibited, except for boating in the Bear Creek Unit in Bear Creek and Maxwell Drain. In order to provide undisturbed staging habitat for migratory waterfowl, access to other parts of the NWA is restricted, and all other activities within the NWA require a permit.

More information on access and permitting for Saint Clair NWA can be obtained by contacting the Environment and Climate Change Canada regional office.
