Big Creek National Wildlife Area
Notice
Welcome to Big Creek National Wildlife Area.
Big Creek National Wildlife Area is open to the public for day-use only. Due to ongoing site maintenance in the Big Creek Unit, the south dike loop will be closed until Spring 2024. The parking lot, north viewing tower, public washrooms and north dike loop will remain open until construction begins in Summer 2023. During construction, the entirety of the Big Creek Unit will be closed to the public until construction is completed. Please note that while Environment and Climate Change Canada establishes trails and infrastructure to support visitor access and use of selected National Wildlife Areas, staff are not always on-site for management of public safety
Please respect the environment and leave no trace.
Big Creek National Wildlife Area (NWA) is located on the north shore of Lake Erie, in Ontario. The NWA has great ecological and social value.
Description
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 a wealth 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 770 hectares (ha). It consists of two units - Big Creek Unit (608 ha), and Hahn Marsh Unit (162 ha). The wetlands of Big Creek NWA are located along the north shore 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:
- eastern hog-nosed snake
- least bittern
- Blanding’s turtle
- eastern foxsnake
- Fowler’s toad
Species of special concern include:
- red-headed woodpecker
- short-eared owl
- eastern ribbonsnake
- milksnake
- monarch butterfly
- swamp rose mallow
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 a result, 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.

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.
Planning your visit
Lovely views of wildlife and wildlife habitats await you atop one of the two viewing towers in the 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.

Access to Big Creek NWA is seasonally restricted and activities are permitted in accordance with the conservation goals 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.
