Beaconsfield, protector of monarch butterflies

Environment March 26, 2025

In partnership with the David Suzuki Foundation, the City of Beaconsfield is proud to participate in the Monarch-Friendly City initiative to help protect and ensure the survival of this iconic North American species. 

The monarch butterfly, known for its incredible migration of nearly 4,000 km to Mexico, is facing an alarming decline in its population, having drastically dropped over the past 20 years in North America. To support their survival, planting milkweed is crucial. 

This native perennial is one of the only plants on which monarch caterpillars feed, consuming its leaves. Often overlooked or mistaken for a weed, the common or Syrian milkweed (Asclepias syriaca) nevertheless plays an essential role in the reproduction and survival of monarchs. 

Besides helping monarch butterflies, milkweed is beneficial to various pollinators, such as hummingbirds, bees and other insects, who feed on its nectar. Its seed pods can also be used to produce coat insulation, thanks to the silk found in its fibres. 

Recognizing the importance of this issue, the City has landscaped a green space at the corner of Beacon Hill and St-Charles, where milkweed was planted last fall. We also encourage residents to do the same in their own gardens. With this simple action, we can all contribute to the survival of monarchs and the preservation of biodiversity.
