Description

Scotch Bonnet Island National Wildlife Area (NWA) supports significant populations of colonial nesting waterbirds in Lake Ontario. Scotch Bonnet Island NWA is a small, 1-hectares (ha) island, located approximately 4.8 kilometres (km) from the mainland in eastern Lake Ontario, off the west shore of Prince Edward County, Ontario. The island is composed of solid limestone outcroppings around the perimeter and barren ground in the interior. The island is named after one of three north-south trending rises of glacio-lacustrine clay and till, known as the Scotch Bonnet Ridge.

This NWA was established in 1979 to protect colonially nesting waterbirds and as a site for long-term research. Every spring the island comes alive with the arrival of large numbers of colonial waterbirds, primarily Herring Gulls and Double-crested Cormorants that breed on the island or that rest there throughout the summer. The island shelters about 110 pairs of Herring Gulls, the largest colony of this species in Lake Ontario, with approximately 500 to 1000 immature Herring Gulls using the island as an overnight roosting area throughout the summer. In 2009, Scotch Bonnet Island was the eighth largest cormorant colony (896 nests) in the Canadian waters of Lake Ontario. The island is also a stopover site for migratory birds, especially waterfowl and shorebirds, during spring and fall migration along the Atlantic Flyway.

Its isolation, stable substrate and long history of use by nesting colonial waterbirds make Scotch Bonnet Island NWA an important site for conservation and long-term research. In the early 1970s, the Canadian Wildlife Service began to monitor persistent toxic chemicals in the eggs of Herring Gulls. Obtaining annual nesting records assists in determining breeding success, population changes, types of species breeding on the island, and determine population trends over time. Scotch Bonnet Island NWA is one of more than 15 Herring Gull sites in the Great Lakes that are visited each year as part of this long-term study. There are no records of any species at risk inhabiting the island.

Management

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 and Climate Change 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 and Climate Change 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 Scotch Bonnet Island NWA is not permitted. There are no roads, trails or facilities maintained at Scotch Bonnet Island NWA and public visitation is prohibited in order to protect the nesting birds from disturbance. Some activities may be permitted in the wildlife area in accordance with the conservation goals of the NWA management plan and include research and monitoring of colonial waterbirds. The ruins of a former stone lighthouse remain on the island as well as a steel-framed light tower maintained as an aid to navigation. However, the waters around the island are accessible and popular for recreational boating and fishing in the summer months. The popularity of the local area for various recreational activities is an increasing challenge since noise and wave action from boats and human presence are also known to cause birds to flush off their nests, or in some cases abandon nests, eggs and young.

Permits are required to visit and to conduct research, surveys and monitoring, and must be obtained from the Canadian Wildlife Service. More information on access and permitting for Scotch Bonnet Island NWA can be obtained by contacting the Environment and Climate Change Canada regional office.
