Topham Pond Invasive Species Removal

June 2024 in Collaboration with Toronto Nature Stewards

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 Ontario 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.

My name is Lidija Nikolic and I am a resident of Mount Dennis neighbourhood of Toronto. I am a Lead Steward with Toronto Nature Stewards and I help regularly with weeding and leading new members to help rid Topham Pond of invasive plant species. I take great pride in all Toronto parks and want to work towards allowing native flowers, bushes and trees to flourish in our parks. A big part of my work is educating others on identifying invasive plants and how to help weed them out in order to give light and air to native plants so they may thrive. I am honoured that Events HNP has agreed to collaborate with Toronto Nature Stewards at Topham Pond to weed out invasive plants.
