The Walley Creek Streamkeepers, in partnership with the City of Nanaimo, Snuneymuxw First Nation, and Department of Fisheries and Oceans (DFO), is undertaking a restoration project this summer to make the creek healthier for the fish and other animals that live there. Walley Creek has resident cutthroat trout, and has the possibility to support Coho salmon.
In-stream work can only happen during the window of August 15 to September 15. This is to prevent damage to sensitive fish habitat. In-stream work requires a permit from the Provincial Government, and is done with the greatest amount of care possible, with the goal to leave the fish habitat better. Outside of this time, nothing should ever enter or block the water – not humans, animals, or tree parts. If branches and other “small woody debris” incidentally enter the water (through storms or getting flushed downstream) volunteers must remove blockages, with permission from DFO, the City and the Province.
2021 planned In-stream Work:
Again this year we deferred our annual invasive removal with Ecole Hammond Bay students, since the public health regulations aren't changing to allow large outdoor gatherings until after June 15. For now, we're working with our small group of volunteers to remove invasive plants in the riparian area between the gravel path and Walley Creek adjacent to Ecole Hammond Bay.
Last year we almost eradicated the thistle that had completely overtaken the area. That allowed other invasive plants to thrive, so this year we are tackling Himalayan blackberry, Daphne (Spurge-laurel), English Ivy, and Bur Chervil. (To identify invasive plants in your area check out the Invasive Species Council of BC website.). These plants are competing with native baby Fir, Cedar, Arbutus and Maple trees, and Salal, Oregon grape and Ocean Spray shrubs for space, light and nutrients.
Our hope is that this concerted effort will eventually allow the native plants to become established, creating a more biodiverse and healthy riparian ecosystem.
Our annual invasive removal in Morningside Park looked a little different this year. With schools closed and everyone practicing physical distancing, we relied on a small group of friends and family to tackle invasives in Morningside Park. Thistle, Daphne, and Ivy out-compete native plants like Oregon grape, ocean spray, and tiny fir and Cedar for sunlight and nutrients. By removing as many invasives as possible, we hope to encourage the diverse native plants to thrive.
Illegal dumping of yard waste continues to be a problem in Morningside Park. Year after year we discover leaves, grass clipping, and even Christmas trees dumped over people's fences into the sensitive riparian area. Years ago someone broke up an old patio and threw the concrete chunks and fence post footings "away". "Out of sight, out of mind" behaviour degrades the slope stability, causes erosion, smothers native plants that are stabilizing the bank and providing shade, and can crush/impede wildlife. Through talking to residents who back onto the creek, we know that most neighbors understand the importance of properly disposing of yard waste. However, a part of restoration still includes removing materials that have been illegally dumped. We're hoping our continued work and outreach eradicates this problem!
Each week since June we've been carefully watering the Oregon grape, ferns, Nootka rose, Snowberry, and Salmonberry that were planted in the riparian area back in March. We are careful not to let any treated "tap" water enter the creek, but volunteers soak the mulch and soil enough that the plants have a chance to get established this spring/summer. We have also spent many hours pulling invasive thistles along the gravel path. This area was disturbed in 2015 when the RDN upgraded the wastewater outfall at Morningside Drive. The City then replanted both sides of the path and installed an irrigation system to support Maple trees, Salal, Oregon grape and ferns until they were established. The irrigation system is no longer being used, and the native plants are being choked out by opportunistic weeds. While we focus on the riparian area and salmon habitat, we recognize the importance of this park land as a corridor and habitat for many other animals. This is one of many tasks we take on in this "adopted" park.
If you have visited Neck Point Park in Nanaimo you have passed over Walley Creek where it flows into Hammond Bay. This section of the creek, upstream of Morningside Drive, flows between private properties and a piece of City of Nanaimo park land. The park is enjoyed by students from École Hammond Bay Elementary School and children from the surrounding neighbourhood. It has a small wetland with potential habitat for salamanders, frogs, and all sorts of mammals and birds. Illegal dumping of yard waste and garbage over the years has done serious damage to a steep slope on the north side, eroding the bank and degrading the riparian zone. It is the location of one of our RDN CWMN water quality monitoring sites, and an area where we have worked hard removing garbage and invasive species in the past two years, with help from Grade 7 École Hammond Bay students.
Dave and Brad added logs and stumps. Nina secured delivery of soil and bark mulch.
Linda and Nina coordinated volunteers (neighbors, Dover Bay eco-club, family members, and Nature Kids)
