Big Creek National Wildlife Area (NWA) is located on the north shore of Lake Erie. The NWA has great ecological and social value. Every year, tens of thousands of migratory birds visit Long Point NWA during migration.


Big Creek NWA is on the north shore of Lake Erie, 3 kilometers (km) southwest of Port Rowan, Ontario. The NWA is at the base of the Long Point peninsula. It is home to awealth of wildlife, including:

  • birds
  • frogs
  • turtles
  • amphibians
  • insects
  • other species

This wildlife relies on wetland habitats. The extensive marshes at the mouth of Big Creek are undisturbed compared to other Great Lakes coastal wetlands. These marshes are a major staging area for waterfowl and more than 200 bird species. These species use the area during their spring and fall migrations.

Big Creek NWA is 771 hectares (ha). It consists of two units - Big Creek Unit (615 ha), and Hahn Marsh Unit (156 ha). The wetlands of Big Creek NWA are located along the northshore of Lake Erie, at the base of the Long Point peninsula. This is also the location of the largest sandspit-marsh complex of the Great Lakes.

Worldwide, many recognize Big Creek NWA for its extraordinary ecological and social value. The Ramsar Convention recognizes it as a wetland of international importance. The Ontario Ministry of Natural Resources and Forestry designate it as a provincially significant wetland. The NWA is part of the Long Point Peninsula and Marshes Important Bird Area. It is also part of the Long Point World Biosphere Reserve buffer zone.

Every spring and fall, tens of thousands of waterfowl visit the Long Point region during annual migration. You can often find up to 100 000 waterfowl (ducks, geese, and swans) resting and feeding at Long Point and its marshes during the peak of fall migration. Over 200 species of birds have been observed at the Big Creek NWA. More than 80 of those species breed at the NWA.

Big Creek NWA also shelters a number of species at risk. Endangered species include the king rail and prothonotary warbler. Threatened species include:

Species of special concern include:

Seasonal highlights within the NWA include:

  • waterfowl migration (spring and fall)
  • turtle nesting (June)
  • monarch migration (August and September)

The water levels within some sections of the wetlands at Big Creek are artificially controlled using an impoundment technique. A system of pumps and dykes mimics the natural rise and fall of water levels. This triggers a diversity of plant growth. As aresult, a greater diversity of wildlife is able to survive and thrive.

The practice of controlling water levels can also be helpful in controlling the growth and spread of invasive plant species. This includes the non-native invasive European common reed (phragmites australis) often referred to as non-native phragmites. The water-level variation has vastly improved the habitats at Big Creek NWA.

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.

Planning your visit

Lovely views of wildlife and wildlife habitats await you atop one of the two viewing towers inthe Big Creek Unit of this NWA. One of these viewing towers can be accessed directly from the public parking lot on Highway 59 (Causeway). The second tower is down a short trail. The trail is open year-round. It runs from the parking lot, through the marsh and along the top of the dyke.

For parts of the year, this trail extends another 1.5 km into the marsh interior. This trail is closed, however, during the fall bird migration to prevent from disturbing the animals while they gain strength for their long journeys.
