Big Glace Bay Lake National Wildlife Area
Public information notice:
The Big Glace Bay Lake National Wildlife Area is temporarily closed to public access due to road upgrades. Once construction is complete, pedestrian access will be restored, and roadside parking will be available. To protect the sensitive beach and dune habitats—home to wildlife such as the endangered piping plover—vehicle access to the beach will be limited to emergency vehicles only.
Big Glace Bay Lake National Wildlife Area (NWA) is located on the northeastern coast of Nova Scotia. It offers habitat for migrating and breeding waterfowl and shorebirds, such as the American black duck and piping plover.
Description
Located southeast of the town of Glace Bay in Cape Breton County, Nova Scotia, Big Glace Bay Lake NWA provides safe fall migration habitat for several key bird species. The most abundant of these are the American black duck and Canada goose. On an average winter day, as a portion of the water usually remains unfrozen, several hundred American black duck and Canada geese can be spotted within the NWA along with dozens of common goldeneye and bufflehead.
Within the NWA, several pairs of piping plover are known to nest on the barrier beach. This is of note, as this species is endangered and protected under the federal Species at Risk Act. Several pairs of common tern and willet also nest in the NWA. These birds prefer to nest in the salt marshes where the terns make their nests in the hummocks within the marsh and the willets along the edges of the marsh. Common tern also nest at the high-water mark and adjacent to the marram grass dune at the northern tip of the barrier beach.

The body of water known as Big Glace Bay Lake is actually a barrier-beach pond. This type of pond forms next to a large body of water and is therefore in constant flux. In this case, the “lake” is located next to the Atlantic Ocean and is influenced by daily tidal fluctuations. A 1.5 kilometre-long sand and gravel beach separates the ocean from the salt marsh and intertidal flats. As it is protected from the larger body of water by the beach, the water in this site is a combination of brackish (a mixture of salt and fresh water) and saline, and it supports beds of eelgrass. This combination makes it particularly attractive to migrating waterfowl.

During the process of creating an NWA at this site, ECCC acquired two additional parcels of land to ensure a conservation buffer exists at the western end of Big Glace Bay Lake. The eastern side of the NWA is vegetated with coastal coniferous and deciduous tree species such as red spruce, red maple, white birch and beech.

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 wildlife 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 in these NWAs are prohibited. 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 NWA. For more information, consult the NWA Management and Activities section.
Any authorized activities are listed in Schedule I.1 of the Wildlife Area Regulations; signage is also posted at access points.

Reason for creation of protected area
The creation and effective management of National Wildlife Areas serve to protect and conserve wildlife and wildlife habitat. The Big Glace Bay Lake Migratory Bird Sanctuary provides protection for migratory birds and their habitat within the Sanctuary. The designation of the Big Glace Bay Lake NWA extends greater protection to all wildlife species and their habitat within an expanded protected area.
