MISSISSAUGA – The City of Mississauga has found a “baaa-rilliant” solution to the growing threat of invasive plant species—using goats as natural grazers. While other Ontario cities are just warming up to the idea, Mississauga has been leading the herd since spring 2024, becoming the province’s first municipality to deploy goats as a tool for managing harmful non-native plants.
Now in its second year, the city’s prescribed grazing program is back in action. The goats have already begun grazing at several parks, including O’Connor Park, Totoredaca Park, King’s Park, and Hewick Meadows—and they’re not done yet.
Natural Grazers, Healthy Ecosystems
The goats are targeting some of the region’s most troublesome invasive species like buckthorn, phragmites, and reed canary grass. These fast-growing plants choke out native species, degrade ecosystems, and pose long-term threats to biodiversity and infrastructure.
Goats offer a chemical-free, eco-conscious alternative to herbicides and heavy machinery—especially useful in hard-to-reach or environmentally sensitive areas. As they munch their way through invasive plants, their hooves also aerate the soil, naturally improving ground structure for native regrowth.
Monitored and Managed Grazing
Each prescribed graze is carefully timed and monitored by professional herders. Goats are rotated through sites to avoid overgrazing and allow native species time to recover. For safety, the goats are only deployed in suitable weather and are enclosed by portable fencing while on site.
To qualify for the program, all goats must be at least one year old and in good health. Depending on the size of the site and target species, a single graze may last from one day to a full week.
Measurable Progress Since 2024
Since the program began, goats have successfully grazed nearly two acres of land across the city. After each round, the City of Mississauga’s Forestry team monitors regrowth to assess the need for additional grazing. A second round of grazing is already scheduled for late summer or early fall.
The initiative is one piece of a broader environmental strategy guided by Mississauga’s Invasive Species Management Plan and Implementation Strategy. It supports the city’s commitment to low-carbon, non-chemical land stewardship and builds public awareness around the importance of biodiversity.
Mississauga: A Leader in Urban Ecology
Mississauga’s goat grazing program has now inspired similar efforts in other Ontario municipalities, cementing the city’s role as an innovator in sustainable urban land management.
By grazing, not spraying, Mississauga is protecting its natural spaces while sparking conversations about ecological health. As the goats continue their work through the seasons, they’re proving that a little bit of baa can go a long way.
