The Hamilton Harbour Fish and Wildlife
Habitat Restoration Project

Scientists with Fisheries and Oceans Canada, the Canadian Wildlife Service, McMaster and Brock Universities and the Royal Botanical Gardens are co-ordinating monitoring and research to advance fish and wildlife habitat restoration throughout the Great Lakes. The Fish and Wildlife Habitat Restoration Project in Hamilton Harbour and Cootes Paradise proposes to create 372 ha of fish habitat, 299 ha of wildlife habitat, 16 km of shore habitat for fish and wildlife and 9 km of trails. Substantial progress has already been made:

• Shoreline rehabilitation and a new trail at Chedoke Creek
• Development of a carp barrier/fishway, aquatic plant nursery and breeding and nursery ponds for amphibians and reptiles in the Cootes Paradise marsh
• Pike spawning habitat, rehabilitated flood plain habitat and a new boardwalk at Grindstone Creek
• Restoration of the lower Grindstone Creek, employing recycled Christmas tree
• Shoreline naturalization and development of underwater reefs at Bayfront Park
• Shoreline naturalization, beach restoration, development of reefs and a new trail at LaSalle Park
• Shoreline naturalization, and the development of colonial nesting bird islands, underwater reefs, trail and lookout at the Northeastern Shoreline
• Sand dune rehabilitation and a new trail at Burlington Beach

In 1997 the operation of a carp barrier/fishway began at the Cootes Paradise marsh, blocking the passage of carp into the marsh during spawning season but allowing the migration of all other spawning fish. As a result, aquatic vegetation has made a dramatic recovery throughout Cootes Paradise and the harbour. Fisheries monitoring has indicated a positive change in the composition of the fish community, including an increase in numbers of top predators and in species diversity. Recently, over 200 spawning pike were counted at the Cootes Paradise fishway. Prior to restoration, only 19 pike were recorded at the fishway. Similarly, waterfowl numbers in Cootes Paradise have increased dramatically due to the increased distribution and abundance of aquatic plants. Birds have been staying longer in the marsh and gaining strength for their migratory flight south.

The Grindstone Creek pike spawning marsh has been a 20-year restoration effort. The Grindstone Trail, connecting Cherry Hill Gate to Sunfish Pond is open to the public and provides educational interpretation and protects the flood plain by directing the large number of visitors to the boardwalk. Tours are open to groups and can be arranged by contacting Royal Botanical Gardens.

To date, habitat restoration efforts and improvements to public access have laid a strong foundation for continuing enhancement. Research and monitoring provide essential feedback for the design and construction of the next phases of habitat and public access projects.
