Completed

Habitat Enhancement work on Timberland Basin was completed in the 1990s.

About the project

The Timberland Basin Habitat was built behind an existing training wall by infilling the former log pond with dredged sandy silt material from the adjacent Timberland Basin channel. Rip rap was placed around the perimeter of the site to retain the material at the appropriate height for establishment of an intertidal marsh bench. Trial planting of the site, predominantly with Lyngbye’s sedge, was undertaken in the early 1990s. Although heavy grazing pressure was experienced due to geese, the site naturally transitioned into low marsh habitat through a combination of transplanting and natural colonization of vegetation.

Establishment of a productive intertidal brackish marsh along this stretch of shoreline has provided food and shelter for a wide range of wildlife. Wildlife that utilize this site include invertebrates (i.e. chironomids), fish (i.e. over 20 species of anadromous and freshwater fish), waterbirds including ducks (i.e. mallards, American widgeon and green-winged teal), Canada geese and gulls, shorebirds, wading birds (e.g. great blue heron) and other wildlife such as raccoons and beavers. Most notably, at high tide this brackish marsh provides important feeding and cover habitat for juvenile coho, chinook and chum salmon and foraging and roosting habitat for waterbirds during high and low tides.
