Description

Vegetation near shore. Sea Wolf Island NWA, vegetation @ Environment Canada.Sea Wolf Island National Wildlife Area (NWA), locally referred to as Margaree Island, is located in the Gulf of St. Lawrence, 4 km off the coast of Cape Breton, Nova Scotia. Margaree Island is a sandstone bedrock formation that is shaped like a whale's back with the highest point of its "hump" about 50 meters above the surrounding sea. The cliffs range from 5-10 meters at the southern end to nearly 30 meters high at points along the northwest side. As such, the island has no protective cove or points of easy access. 

The water surrounding the island supports a wealth of migratory birds. Over forty species of birds and seventy plant species have been recorded on Sea Wolf Island NWA. Colonial birds breeding at the NWA include the Great Cormorant, Great Blue Heron, Great Black-backed Gull, Herring Gull and Black Guillemot. The island also supports one pair of Bald Eagle.

The vegetation of this small exposed island consists of dense White Spruce stands on the lee side, Low Crowberry and Creeping Juniper at southwest portion. A Shrub-grass cover with stunted White Spruce occupies the windward side and north tip.

In addition to the many bird species that make use of Margaree Island a variety of mammals such as Snowshoe Hare, Coyote and Red Fox occur on the island while sea-mammals such as Grey Seal, Mink Whale and Fin Whale frequent the surrounding waters.

Management

Sea Wolf Island NWA, landscape @  Colin MacKinnon, Environment Canada.National Wildlife Areas (NWAs) are protected and managed according to the Wildlife Area Regulations under the Canada Wildlife Act. The primary purpose of NWAs is the protection and conservation of wildlife and their habitat. For this purpose, and according to the legislation, Environment Canada can prohibit all activities in a NWA that could interfere with the conservation of wildlife. Consequently, most NWAs are not accessible to the public and all activities are prohibited. Nonetheless, Environment Canada has the ability to authorize some activities, whether through public notice or the issuance of permits, as long as these are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.

Access to Sea Wolf Island NWA is not restricted and activities may be permitted in accordance with the conservation objectives of the NWA management plan. Public notices listing the authorized activities within the wildlife area are posted at the main access point below the Canadian Wildlife Service cabin.  Public visitation is not encouraged although activities such as hiking, wildlife observation and hunting (subject to provincial and federal regulations) are presently permitted. However, these activities may be subject to change at any time if deemed necessary.

More information on access and permitting for Sea Wolf Island NWA, can be obtained by contacting the Environment Canada regional office
