Description

Originally established in 1978, the National Wildlife Area is comprised of 2 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 National Wildlife Area is listed as a Ramsar wetland, an International Butterfly Reserve, and part of the Eastern Lake St. Clair Important Bird Area (IBA).

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 2 major migratory routes: the Atlantic and Mississippi flyways.

Every year during migration, hundreds of thousands of waterfowl, including the tundra swan, pass through this National Wildlife Area. 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 National Wildlife Area 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:

Management

Under the Canada Wildlife Act, National Wildlife Areas are protected and managed in accordance with the Wildlife Area Regulations. The primary purpose of National Wildlife Areas is to protect and conserve wildlife and wildlife habitat. For this purpose and according to the legislation, all activities in a National Wildlife Area that could interfere with the conservation of wildlife can be prohibited. Consequently, most National Wildlife Areas are not accessible to the public and all other activities are prohibited in all National Wildlife Areas. However, some activities may be authorized through Schedule I.1 of the Wildlife Area Regulations or the issuance of permits as long as they are consistent with the management plan goals for the National Wildlife Area. For more information, consult the National Wildlife Area Management and Activities section.

Access to some portions of the St. Clair National Wildlife Area is restricted to protect wildlife and their habitats from disturbance. Some activities are permitted in accordance with the conservation goals of the National Wildlife Area management plan. Any authorized activities are listed in Schedule I.1 of the Wildlife Area Regulations; signage is also posted at access points.

Authorized activities listed in Schedule I.1 of the Wildlife Area Regulations for St.Clair National Wildlife Area, include:

  1. wildlife viewing on designated roads and trails and in designated areas
