Riverfront Park Tidal Marsh

August 12, 2015

Project status


The Riverfront Park Tidal Marsh Project is located along Riverfront Park in the City of Vancouver and extends approximately 125 metres westward from the south end of Kerr Street.

Prior to marsh construction, the site consisted of a relatively wide intertidal mudflat characterized by woody debris and a narrow fringe marsh along an eroding bank of the north arm of the Fraser River. The habitat was converted to intertidal brackish marsh in May 1993. The site covers a gross area of approximately 0.36 hectares.

About the project

The project site lies along the north bank of the of the north arm of the Fraser River, adjacent to Riverfront Park in Vancouver

The project involved construction of a rock containment berm and placement of appropriate fill material for establishment of an intertidal bench on which a variety of different brackish marsh vegetation, most notably Lyngbye’s sedge, have become established through a combination of transplanting and natural colonization. Establishment of a productive intertidal brackish marsh along this stretch of shoreline, which was previously an eroding and unvegetated slope with low habitat values, has provided food and shelter for a wide range of wildlife. Wildlife that utilize the site include invertebrates, fish (over 20 species of anadromous and freshwater fishes), waterbirds including ducks, Canada geese and gulls, shorebirds, wading birds, 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.

This site has been providing productive fish and wildlife habitat on the north arm of the Fraser River for over 30 years. The port authority conducts regular monitoring to ensure the habitat continues to meet its biophysical objectives.
