Junction Creek Stewardship Committee

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.
