The Junction Creek Stewardship Committee conducts surveys to monitor invasive species in the Junction Creek watershed and collaborates with local community groups to assist in invasive species removal and management. We aim to gain a better understanding of the extent of their impact on our native ecosystems and develop effective management strategies to help conserve native biodiversity in Junction Creek. 

Why are invasive species a concern?
Invasive species are a major threat to biodiversity and can cause erosion along the stream bank. Not only is this a concern for native plants and animals, but for trail users and the community as well. The Junction Creek Stewardship Committee aims to address major ecological concerns associated with the spread of invasive plants along Junction Creek and engage with community stakeholders to encourage greater education and community stewardship.  

The restoration of lost and damaged riparian habitat and aquatic stream features are vital for the recovery of functional ecosystems and to rebuild resiliency to urbanization, invasive species and climate change. As stated by Watersheds Canada, “vegetated buffers are effective in removing over 90% of runoff when compared to non-vegetated shorelines and are critical in mitigating the effects of climate change. These areas provide critical habitat and shade for 90% of aquatic wildlife and 70% of land-based wildlife at some point in their lifetime”. Sections of Junction Creek still exhibit sparse to no riparian buffer and substandard habitat as a result of numerous factors, including invasive plants.  

Invasive Species in Junction Creek

Junction Creek Invasive Species Past Projects
2022 Invasive Species Project  
In 2022, the JCSC had two funded projects to help address invasive species in the Junction Creek watershed and provide resources to empower community-led stewardship. Click to read more.

2023 Invasive Species Project
In 2023, the JCSC launched an “Empowering Youth in Invasive Species” project aimed at empowering youth and community-led stewardship to prevent the spread of invasive species along Junction Creek. The project was made possible with support from the Invasive Species Centre’s Invasive Species Action Fund and the Ontario Ministry of Natural Resources and Forestry. 

As part of the project, JCSC delivered guided walks and invasive species pulls along Junction Creek with the help of youth and community members; providing the tools and knowledge to empower stewardship in a way that is inclusive, enjoyable and barrier-free. Additionally, JCSC provided 60 invasive species management kits to youth and community members, helping individuals make a difference and stop the spread of invasive plants.  

The project also supported the development of a site-specific 5-year management plan for a patch of invasive Japanese Knotweed in the Flour Mill by the arboretum. With the funding, we were able to acquire the materials and supplies needed for the site, outreach handouts for the community, and developed informative signage about the management project. The removal and control of the patch of Japanese Knotweed is planned to commence in June 2024. Stay tuned for more details.

You can help reduce invasive species in your watershed by planting native species in your gardens and yards, cleaning footwear and boats between use in different locations to prevent the spread, learn how to identify invasive species, reporting sightings to the Ontario Invading Species Awareness Program, and volunteering at an invasive species removal event in your neighbourhood.  

Invasive species that have been commonly found in the Junction Creek watershed include Japanese Knotweed, Himalayan Balsam, and Eurasian Water Milfoil. Check out the Junction Creek Invasive Plant Guide for more information.
