Salt Marsh Restoration in the K’ómoks Estuary at Dyke Slough
A tidal marsh is a type of habitat found along coasts and estuaries which is regularly flooded by the tides. The vegetation found in these areas has evolved adaptations to this inundation by marine waters. These marshes are among the most productive ecosystems in our region, with a number of species including waterfowl, other migratory birds, and salmonids using these marshes as habitat. They are home to stunning plant biodiversity and have been important sites of cultivation and harvest of staple food plants, such as silverweed (Potentilla egedii), Camas (Camassia spp.) and Northern riceroot (Fritillaria camschatcensis) for Coast Salish peoples.
Human influences have led to loss of marsh in the estuary. Some anthropogenic influences include climate change, increased storm frequency and intensity, and grazing from resident Canada Geese populations.
The map on this page shows lost, historic salt marsh in red, degraded salt marsh in orange, and intact salt marsh in light green. The area in green with hash marks shows a marsh restoration project under-taken in March of 2021 by Project Watershed, funded by Fisheries and Oceans Canada through the Coastal Restoration Fund.
This restoration built up a new marsh platform to replace lost, historic tidal marsh. The newly built platform (bottom photo) was then planted, all to help support wildlife and coastal resiliency in our thriving estuary.
Photo documentation of forage fish spawning habitat is valuable in our aim to protect these important nursery areas. Photos provide a story of each individual beach over time.
These cards help protect & restore habitat in the Comox Valley. A card will be sent to a special someone when you make a donation.
Happy Technician Tuesday! Last week our team partnered with Laura Terry from the Department of Fisheries and Oceans (DFO) to conduct a beach seine at Hollyhock Flats.
Once again we will enliven the K’ómoks Estuary with the merry sounds of Christmas Carols. There will be a few changes to this year’s event to keep everyone COVID safe, however, singing and merriment will continue to be the core of this activity.
Happy Technician Tuesday! Our team has been working on plant guides for future monitoring at Kus-kus-sum and Hollyhock flats.
Happy Technician Tuesday! Our team recently checked on the Lyngbye’s Sedge (Carex lyngbyei) planting in Hollyhock Flats and we’re happy to report that they are growing well.
