Urban nature enthusiasts are venturing beyond their personal gardens this spring, armed with trowels and seeds, joining forces with others. Soon they will be planting the sides of highways, gardens of city halls and school parks with flowers and shrubs native to their neighbourhoods.
It’s all part of the Butterflyway Project, a David Suzuki Foundation initiative that aims to create a highway of gardens for butterflies and bees — called a butterflyway — across each city.
Beginning in March, the Butterflyway Project rounded up volunteers in Victoria, Richmond, B.C., Toronto, Markham, Ont., and Montreal to act as butterfly rangers. Rangers in each city coordinate partnerships with schools, companies and city councillors to create pollinator gardens for the city’s bee and butterfly populations.
The goal of the project is to have the rangers and their partners plant at least 12 pollinator patches, which are gardens filled with native wildflowers, plants and shrubs, and spread them across the city. “The idea is to thread together dozen or so of these patches and connect the dots,” says Jode Roberts, the project’s manager. “It’s a neat little exercise to zoom out and look at your neighbourhood as a wildlife corridor.”
Butterflies forage for their food, sometimes across great distances. The monarch butterfly, for instance, travels from Canada to Mexico, though most species of butterfly in Canada don’t travel that far; many will flit across a city, or a neighbourhood, in search of food.
The pollinator patches are also helpful to the bees and other insects that benefit the ecosystem. Unlike butterflies, bees are central place foragers, meaning they will forage and then return to a home base. Honeybees can fly up to 10 kilometres.
“Part of this project is giving people a practical outlet for their concerns over climate or energy or their environmental footprint,” says Roberts.
Pezzack says she plans on running the Butterflyway Project similar to a barn raising, where a few families get together and complete a small project and then bring more families into the mix to complete a bigger project. “We’re starting small and expanding from there, generating more awareness and interest as we go.”
Though the project is focusing on five Canadian cities, there is nothing stopping residents of other areas from creating their own pollinator patches to help the butterflies. Here are a few helpful tips to get you started.
Grow native wildflowers
This is the first and most important step of starting a butterfly garden. Butterflies need flowers with nectar, and leafy plants to act as hosts for their eggs. It’s important to have flowers that bloom all season, not just in the spring, so grow a wide variety of flowers.
Have a tree or a shrub
Shrubs, bushes and trees make for great shelter for bees, butterflies and birds. The foundation suggests trees that flower or bear fruit.
Create a “bug hotel”
A bug hotel is just a fun term for a pile of wood. Be a slightly lazier gardener; let the sticks pile up and rot. It makes a good home for bugs.
Have sunny soil patches for bees
Bees and butterflies like sun as much as we do, so let them tan in your garden. Set a rock somewhere in the garden for the bugs to sun themselves.
Have a bath for the bees and butterflies
Set a shallow container of water with a flat rock in the middle. It creates an island so the butterflies and bees can drink and bathe without drowning. And yes, bees and butterflies bathe.
Find out what species of butterflies and bees are local to your neighbourhood, and what flowers would be best suited for them and your garden. Butterflies need different types of flowers depending on the species, so brush up your local horticultural knowledge.
Get the neighbours involved
Remember, the idea of the Butterflyway Project is to create a highway of habitat. That means each city needs lots of pollinator patches.
