Mohawk Island National Wildlife Area
Mohawk Island National Wildlife Area (NWA) is a small, 4-hectare (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.
Description
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
- double-crested cormorants
The natural features of the island provide excellent loafing habitat as well as refuge from predators. It offers 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. The waterbirds are also part of long-term toxicity monitoring studies undertaken by Environment and Climate Change Canada.
The island 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
- scaup
Shorebirds such as sandpipers are also often present. 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.

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 other activities are prohibited in all NWAs. 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.
Access to the Mohawk Island NWA is seasonally restricted. Public access is prohibited from April 1 to August 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. Any authorized activities are listed in Schedule I.1 of the Wildlife Area Regulations; signage is also posted at access points.
