Aquatic invasive species pose a serious threat to the delicate ecosystems of the North Okanagan, an area rich in lakes, rivers, and wetlands. These waterbodies are vital habitats for diverse wildlife and are popular destinations for residents and seasonal tourists who engage in water-based recreation, wildlife viewing, fishing, and angling. In 2024, with financial support from the North Okanagan Conservation Fund Grant Program, the Invasive Species Council of B.C. launched an ‘Aquatic Invasive Species Control’ project. This one-year project aimed to safeguard the biodiversity and ecological health of the North Okanagan’s high-use aquatic ecosystems by raising awareness and enhancing on-the-ground efforts to manage aquatic invasive species such as yellow flag iris.
Effective prevention of aquatic invasive species in the North Okanagan hinges on education and awareness of both residents and visitors. By informing the public about the simple practices they can take to prevent the spread of aquatic invasive species, this project sought to foster a culture of stewardship. Visual reminders at key entry points, such as boat launches, are essential tools to reinforce these messages. The North Okanagan faces significant risks from species like zebra and quagga mussels, Eurasian watermilfoil, and parrot’s feather. To help mitigate these threats, nine Clean, Drain, Dry signs were installed at priority locations, including public boat launches at Sugar Lake 9 Mile, Sugar Creek, Specs Lake, Grizzly Lake, Cooke Creek, and Hidden Lake Recreation Sites, as well as Riverside Community Park along the Shuswap River. These signs are intended to raise public awareness and encourage people to take preventative action.
To build local capacity for managing invasive species, the project also focused on hands-on learning and control measures. On September 16th, a workshop was held in Armstrong to address invasive yellow flag iris, a plant known for altering hydrology, disrupting ecosystem functions, and diminishing critical wildlife habitat. The workshop brought together 30 keen stewards who were trained in effective control techniques and then applied their knowledge to tackle an existing infestation along Meighan Creek. The workshop was facilitated by Dr. Catherine Tarasoff of AgroWest Consulting, a seasoned expert in the management of yellow flag iris in B.C. Presently, all reported yellow flag iris infestations in the region are small, offering a valuable opportunity for early intervention before the species can spread and cause further ecological damage. A second control effort was conducted on November 13th in Vernon, targeting a small yellow flag iris infestation in a drainage ditch connected to Swan Lake, an area crucial for local wildlife and migratory birds.
In addition to sign installations and hands-on control activities, the project also prioritized public outreach to broaden awareness of aquatic invasive species among both residents and visitors. 893 people received information and resources about aquatic invasive species during in-person outreach efforts conducted at recreation sites and local events. The Invasive Species Council of B.C. is grateful for all those who supported this important regional project, including the Ministry of Forests, Ministry of Transportation and Infrastructure, City of Armstrong, North Okanagan Naturalist’s Club, Riverside Community Club, Awaken Inquiry & Adventure Okanagan, Dr. Catherine Tarasoff, Kim Fulton, and Jeremy Borges.
Together, through continued education, collaboration, and active participation, we can help prevent the spread of aquatic invasive species and protect the unique lakes, rivers, wetlands, and biodiversity of the North Okanagan.
