Project Watershed is currently working on a mapping and inventory of reed canary grass in the K’ómoks Estuary. This invasive European cultivar, brought in with agricultural practices, is taking over from native grass species and provides little value for wildlife. Few species will eat it and it grows too thickly for animals or waterfowl to use it for cover or nesting. Foraging juvenile salmon have feeding opportunities reduced in areas dominated by this grass. It also out-competes trees and shrubs which provide important stream-side cover and keep water temperatures cooler. In particular, dense stands are starting to form in the Hollyhock Marsh conservation area, Dyke Slough and the lower reaches of Mallard Creek. In fact it is starting to constrict the creek impeding fish access.
As part of our work to control and manage this invasive grass we have been doing some test treatments. Specifically mowing, mowing/shading (with cardboard) and digging it out. We are currently monitoring how effective these treatments are, and we will soon be developing a control plan for long-term management of this invasive plant. You may notice our crew out in the estuary this summer doing some of this work. If you come across areas where we are working on controlling the grass with cardboard we ask that you not disturb these sites.
We would like to acknowledge the financial support we have received for this project from the Fish and Wildlife Compensation Program and the cardboard that has been kindly held and donated by Mountain City Cycle.
