Invasive species are non-native organisms that have been introduced often due to human activities in an environment they do not naturally belong to. These species can significantly disrupt local ecosystems by outcompeting native species for resources, spreading diseases, or causing habitat degradation. Due to their potential to cause severe ecological damage, removing invasive species as soon as possible is crucial.

Situated in the southeast corner of Eglinton Flats, Topham Pond serves as an important natural habitat for a variety of native species including fish, birds, and amphibians. Managed by the Toronto and Region Conservation Authority (TRCA) and the Ministry of Natural Resources (MNR), the pond was designed to capture filtered rainwater and maintain ecological balance. The surrounding bowl-shaped park, with its diverse tree cover and habitats, has been a key area for conservation efforts such as cleanups, tree planting, and wildlife support. Removing invasive species from this area not only helps protect and enhance the biodiversity but also supports the ongoing conservation initiatives aimed at preserving this vital ecosystem.

On June 15th, 2024, HNP Canada hosted an invasive species removal event at Topham Pond. Volunteers, HNP Executives, and Lead Stewards from Toronto Nature Stewards worked together to successfully remove four different types of invasive species. The event, which ran from 10:00 AM to 1:30 PM, was a rewarding experience for everyone involved.
