Mohawk Island National Wildlife Area
Mohawk Island National Wildlife Area (NWA) is a small, 4-hectares (ha), sparsely vegetated limestone outcrop located in eastern Lake Erie. It lies approximately 20 kilometers (km) to the southwest of Port Colborne, Ontario, near the mouth of the Grand River. The island consists mainly of open limestone barrens with an elevated gravel bar along the eastern shoreline; it is greatly affected by the strong wind events that frequently overwash the entire island. The sparse vegetation is limited to thin soils found in small depressions and rock crevices. Mohawk Island was once named Gull Island because of the large numbers of gulls and terns that rested on the Island.
The NWA was established in 1978 to protect colonial nesting waterbirds. It is an important nesting site for several species of waterbirds, primarily Herring Gulls, Ring-billed Gulls, Common Terns, and Double-crested Cormorants. The natural features of the island provide excellent loafing habitat as well as refuge from predators, offering easy access to food supply, and having minimal human disturbance for the young nestlings. Populations of the colonial waterbirds at Mohawk Island NWA have been monitored since the 1970s, and are part of long-term toxicity monitoring studies undertaken by Environment and Climate Change Canada.
The island also provides a stopover site for many species of migratory birds, especially waterfowl and shorebirds during spring and fall migration. Waterfowl often seen in the area include species such as Mallard, Canada Goose, Common Goldeneye, and Scaup. Shorebirds such as sandpipers are also often present as they pass through and use the island for loafing and as a stopover site when crossing Lake Erie along the Mississippi and Atlantic flyways.
Although the surrounding area supports a wealth of bird species, there are very few other types of animals present on the island. The sparse terrestrial vegetation offers little cover or food for vertebrate residents. Eastern Garter Snakes live among the foundations of the lighthouse on the island; this is the only other wildlife species reported as surviving on the island. To date, no species at risk have been recorded on Mohawk Island NWA.
More information on Mohawk Island NWA is provided in the summary table below.

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 the Mohawk Island NWA is seasonally restricted. Public access is prohibited from April 1 to July 31 every year to protect migratory birds during nesting. Some activities may be permitted in accordance with the conservation objectives of the NWA management plan. Public notices listing the authorized activities are posted at access points. Public access for day use is allowed only between September 1 and March 31 (outside the breeding season) for activities such as bird-watching, viewing the lighthouse, recreational fishing (no lead sinkers) and swimming. Overnight camping, open fires and hunting are prohibited at all times. Mohawk Island NWA is a well-known local landmark and the waters around the island are popular for recreational boating and fishing in the summer months. Fishing must be done in accordance with the Ontario fishing regulations, which require possession of a recreational fishing license issued by the Ontario Ministry of Natural Resources. Permits are required to conduct research, surveys and monitoring, and must be obtained from the Canadian Wildlife Service.
More information on access and permitting for Mohawk Island NWA can be obtained by contacting the Environment and Climate Change Canada regional office.
