Canyon Meadows Bee Boulevard self-guided walk

Welcome to the Canyon Meadows Bee Boulevard!

This self-guided walk allows you to explore a naturalized section of Calgary Parks land that was established in 2017 to create habitat for native pollinators. The best time of year to explore this site is from May – October. The route is just under one kilometer (one way). Follow along on Google Maps to learn about naturalization, native bees and how to become a Polli-Neighbour! Parking can be found along Parks Estates Drive SE south of Canyon Meadows Drive SE.

This specialized pollinator corridor contains native shrubs, grasses and flowers that are salt tolerant, drought resistant, and attractive to native pollinators. There are several enhancements that create habitat appealing to pollinators, including a sand bed for ground-nesting bees, bumble bee houses, an interactive leaf-cutter bee display and specialized areas for cavity-nesting bees.

Stop 1: Median restoration

2018

2020

Historically, most municipal conservation efforts have focused on the preservation of large natural areas within our city. The Bee Boulevard illustrates a different approach to managing our open spaces, in which native grasses, shrubs and wildflowers are incorporated into medians, greenspaces and City parks. Naturalized areas like these enhance biodiversity in our city, require less maintenance in terms of weeding, watering and mowing, and provide public education and stewardship opportunities.

The naturalization of the 0.6ha median along Canyon Meadows Drive presented some unique challenges. Factors such as the low quality and volume of the soil, salinity and sediment loading from road maintenance, and the medians' shape and location created issues for the establishment of vegetation at the site.

Through consultation with specialists, these obstacles were able to be overcome. The top 10 cm of topsoil was removed from the medians, and an organic soil amendment was added, along with new loam and gypsum. The area was then hand-seeded with salt and drought-tolerant flowers and grasses. The plants have now established in most areas, and species include Blue flax, Canada milkvetch, Tufted hairgrass, Rocky Mountain fescue and Slender wheatgrass. 


Stop 2: Main flower bed

To add value to the naturalization of City-owned parcels of land, the City partnered with researchers to investigate and document Calgary pollinators and the types of vegetation they prefer. Through a unique partnership between the City of Calgary, the University of Calgary, Mount Royal University, and the David Suzuki foundation, this land corridor was transformed into an oasis for pollinators and an invaluable research site for local bee experts.

From above, the main flower beds before you take a take the shape of a large flower. Each ‘petal’ is edged with recycled sandstone. Before restoration, this flowerbed contained many non-native grass species and invasive plants. After removing this vegetation, a groundcover of Blue flax and Rocky Mountain fescue was planted, as were many types of native shrubs and wildflowers. To ensure resources for pollinators throughout the growing season, these flower beds contain plants that bloom from early spring, such as golden currant, gooseberry and alpine forget-me-not, to late-season bloomers such as goldenrod and sunflowers.

Thanks to the stewardship efforts of a local school, this area also contains over 600 showy milkweed plants, which are an important food source for butterflies. Taller plant species were placed closest to Canyon Meadows Drive to maximize floral encounters for pollinators and direct them upwards toward the median plantings.

Take a moment to explore the interactive solitary leafcutter bee display. Over 70% of native bees in Alberta are solitary! Solitary bees nest in tunnels, cavities, or the ground and do not have hives or produce honey or wax like bumblebees and honey bees do. Solitary bees come in all shapes and sizes and are often mistaken for other insects such as flies and wasps. Solitary bees are not aggressive (many do not even have stingers) and are some of the most effective pollinators we have in our city.

Bumblebee

Unlike solitary bees, bumblebees are known as ‘social bees’ and live in small colonies composed of a queen, worker bees and drones. All members of the bumblebee colony die off before the winter, and only the mated queens hibernate. Queens emerge in the spring and build nests to lay eggs. Bumblebees prefer to nest in piles of plant debris, tree cavities, and old rodent holes. Several nest boxes have been installed at this site to provide additional nesting habitat for native bumblebees. 


Stop 4: Large bee hotel

Most of the infrastructure at this site is made from recycled materials. The pathways are made from recycled concrete, sandstone boulders were repurposed as planters, and native plants were brought in from another park that was being redesigned. The site also contains bee habitat enhancements, including bumblebee nest boxes, solitary bee hotels, nesting logs, and sand beds for ground-nesting bees.

Bee hotels are wooden nesting structures where solitary tunnel-nesting bees can lay their eggs. Females lay eggs in the late summer, and the eggs develop over the winter before hatching in the spring. The bee hotel in front of you is composed of logs that were removed from a golf course during a pathway realignment project. These logs were drilled with holes to function as homes for cavity-nesting bees such as carpenter bees and mason bees. Most cavity-nesting bees in Alberta prefer to nest in holes ⅓’’ – ¼’’ in diameter.

Stop 5: Sandstone beds

Many of the plants in these sandstone flower beds were salvaged from another park undergoing construction. Look for species such as Yarrow, Gaillardia, Curly cup gumweed, and Northern bedstraw. The flower beds in this area are weeded once every year, and thatch is removed when required. Seed from the native plants grown here is collected for future plantings in other City parks.

These flower beds not only provide resources for pollinators throughout the growing season, they also provide nesting habitat for native bees. While some solitary bees construct their nests in tunnels or cavities, many prefer to nest in the ground. The loose sand and soils in these sandstone planters provide excellent habitat for ground-nesting bees such as mining bees and plasterer bees.


Stop 6: Additional bee habitat

In 2019, Calgary was named Canada’s 36th Bee City! This designation highlights the City’s commitment to providing habitat and resources for local pollinators. Projects such as the Canyon Meadows Bee Boulevard not only provide resources for native bees and insect pollinators, they also provide excellent opportunities for pollinator-related research. Current research focuses on bee biodiversity and the floral preferences of bees in our parks and greenspaces. Results of this research help inform restoration work in our city and guide decision-making concerning which plants to use in different areas.

Recent research from the University of Calgary shows that our city has loads of native bees - with 199 different species documented thus far. Calgary may contain more types of bumblebees than any other city in North America, 3 of which are endangered species! In 2018, two endangered gypsy cuckoo bumblebees were found at the Canyon Meadows Bee Boulevard.
