Sea Wolf Island National Wildlife Area

Sea Wolf Island National Wildlife Area (NWA), locally referred to as Margaree Island, is located in the Gulf of St. Lawrence, 4 kilometers (km) off the coast of Cape Breton, Nova Scotia.

Description

Margaree Island is a sandstone bedrock formation. The Island 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. The highest points are located along the northwest side and reach nearly 30 meters. 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:

  • great cormorant
  • great blue heron
  • great black-backed gull
  • herring gull
  • black guillemot
  • bald eagle (one pair)
Great blue heron

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.

The great cormorant colony, consisting of upwards of 100 pairs, is significant since there are few colonies of these species known to occur in the region. Northern gannet and common loon are regularly observed around the island. In addition to the many bird species that make use of Margaree Island a variety of mammals occur on the island and frequent surrounding waters such as:

  • snowshoe hare
  • coyote
  • red fox
  • grey seal
  • mink whale
  • fin whale

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 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, since colonial nesting birds are susceptible to human disturbance, although the activities permitted are:

  • hiking
  • wildlife observation
  • recreational hunting (subject to provincial and federal regulation)

However, these activities may be subject to change at any time if deemed necessary. To protect nesting birds, and for safety reasons, cliff climbing is not permitted.

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