Conservation

"One of the most important and progressive education centres in existence, and its diverse and unique curriculum is the envy of many."

Rob Bell-Irving, Community Advisor, DFO


Overview

Cheakamus Centre values responsible stewardship of this remarkable 420-acre ecological reserve, which includes the Dave Marshall Salmon Reserve. Together with conservation partners, Cheakamus Centre strives to protect the diverse natural communities that benefit a variety of wildlife species. Responsible stewardship requires thoughtful management. The maintenance, restoration, and enhancement of habitat and achieving a balance between interaction and protection on the site remain a key priority for Cheakamus Centre

Cheakamus Centre, Fisheries and Oceans Canada (DFO) and various partners such as Bridge Coastal Restoration (BC Hydro), Squamish Watershed Society and Squamish Nation have been working together since 1981 to restore historic salmon habitat throughout the property. These projects are part of a large, multi-phased initiative to restore the side channel habitats of the Cheakamus River which provide secure refuges for salmon from the winter floods common on the Cheakamus River. These restored habitats support thousands of spawning chum, coho, pink, chinook, steelhead and sockeye salmon each season. This biologically rich portion of the watershed called "Paradise Valley" provides critically important habitat for overwintering populations of bald eagles which depend on the salmon for a food supply. As a result of these successful partnerships, Cheakamus Centre now has the most restored side-channels in the Squamish Watershed.

Dave Marshall Salmon Reserve

The great numbers of salmon presently spawning on the Cheakamus Centre property are the result of over three decades of combined efforts to rebuild and restore salmon habitat. Dave Marshall was a respected Fisheries Biologist who was responsible for many of the salmon spawning channels that exist today at Cheakamus Centre.

The concept of the groundwater spawning channel was pioneered by Dave Marshall and engineer Rheal Finnigan of the federal Salmonid Enhancement Program. The first groundwater salmon spawning channel, the Upper Paradise channel, was created along the Cheakamus River in 1982. Since that time further salmon spawning and rearing habitats have been developed in the Paradise Valley, with many of them located at Cheakamus Centre.

The Dave Marshall Salmon Reserve is dedicated to Dave who passed away in 1999. His passion for the salmon resource inspired many who knew and worked with him. His legacy for future generations will be the sounds of salmon splashing in the night, the soft rush of an eagle taking flight and the dance of the dipper feeding on salmon eggs.

The salmon reserve features restored habitats that fall into three broad categories. Each of these types of habitat is used somewhat differently by the various species of salmon.

Kisutch and Upper Paradise channels are examples of groundwater spawning channels. They are constructed by digging old river channels deeper so that they intercept clean groundwater flowing just below the surface of the river floodplain. Winter or summer, these habitats have a steady flow of clean groundwater. Spawning chum salmon use these habitats extensively, as do spawning coho salmon. They also provide good summer habitat for young coho salmon fry.

The various pond complexes at Cheakamus Centre provide good habitat for young coho salmon during their first summer of life. Ponds are considered critical habitat in the winter for young coho salmon which seek out their deep quiet waters as a refuge from the winter storms in the Cheakamus River.

River fed channels are connected directly to the Cheakamus River by means of a pipeline which regulates the flow of water to these habitats. The water in these channels can be coloured by glacial silt in the summer and eroded soils during the heavy rain storms of winter. The more variable flows and temperatures found in these habitats are preferred by pink salmon and coho salmon and lightly used by chum salmon. The Moody and Farpoint channels are examples of this type of habitat.

These diverse habitats support over 40 000 chum, coho, pink, chinook and steelhead salmon which return to spawn at Cheakamus Centre from August to February annually.

By early winter the eagles increase their presence, arriving for their winter feast of the spawned out salmon within the reserve which is further protected by Nature Conservancy of Canada environmental covenant.

This intricate cycle of life and death continues in part because of the many dedicated people that have ensured salmon will always have a place at Cheakamus Centre. It is Dave's legacy to the children of today, that they respect the environment, honour the salmon and pursue with passion their own life's calling.
