With a scoop of the net, the hidden wonders of the Humber River come to life. From darting crayfish to tiny aquatic insects wriggling through the water, an ordinary stretch of river suddenly becomes a world full of movement and discovery.

At Summer Nature Day Camp, campers step into the river to explore aquatic life up close and see firsthand how freshwater ecosystems are connected.

One walk, many ecosystems 🌿

On World Biodiversity Day, we’re exploring the Carolinian Life Zone, home to the highest diversity of habitats and species in Canada, where forests, wetlands, meadows, and river systems overlap to support biodiversity across a single landscape.

In just one walk, these connected ecosystems transition from shaded forest to open meadow and the Humber River, creating a range of habitats that support Carolinian species, including trillium wildflowers, eastern redbud trees and Painted Turtles.

You may have heard that bees and other pollinators help support more than 75% of the world’s food crops. But did you know there are more than 360 native bee species in Toronto? Including the city’s official bee, the Metallic Green Sweat Bee.

This World Bee Day, we’re celebrating the diversity of native bees that help pollinate the flowers, trees, and plants that support biodiversity across Toronto’s urban landscapes. 🌼🌿

From fuzzy bumble bees to tiny solitary bees nesting in the ground or tucked into hollow stems, native bees are already hard at work across the city, including:
• Metallic Green Sweat Bee — small with a bright, jewel-like green shimmer
• Bumble Bees — large and fuzzy, moving slowly between blossoms
• Leafcutter Bees — tiny bees known for cutting neat circles into leaves
• Mining Bees — early spring ground-nesting bees

Where curiosity meets care for the planet ♻️🌎

During our Healthy Planet, Healthy Lives week of camp, we explore what it means to live more sustainably, take action for the environment, and understand how even small choices can grow into something bigger. 🌿

From the ins and outs of recycling to dipping nets into the Arboretum’s ponds in search of aquatic life, campers aged 5 to 12 discover how deeply connected the natural world is—and the important role they play within it.

Through hands-on exploration and play, they’ll start to see everyday choices in a new way—learn more and register at humber.ca/arboretum/camps.

This National Volunteer Week, we’re shining a light on our dedicated team of garden volunteers and the hard work they put into keeping Humber Arboretum growing all year long! 👩🏻‍🌾🧑🏽‍🌾

From spring planting to winter greenhouse care, join us in saying a BIG THANK YOU to the team for the hard work, knowledge, and care they bring year-round.

🌱 Spring
· Help select and plan seasonal vegetable crops
· Bring the gardens and planters to life across the site, including:
· Sowing 95% of vegetable seeds in The Humber Food Learning Garden and 80% of annuals in planters around the buildings and parking lots
· Planting the All-America Selections Display Gardens and The Garden of the Rising Moon

🌼 Summer
· Help maintain The Garden of the Rising Moon, The Humber Food Learning Garden, and site planters through weeding, pruning, deadheading, training, and harvesting crops

🍂 Fall
· Put the gardens to bed by removing annuals and vegetables, and cutting back and dividing perennials
· Prep the greenhouse for winter by potting tropicals and overwintering plants such as dahlia and grasses for education programs at Humber Polytechnic

🪴 Winter
· Keep the greenhouse organized by spacing, rotating, and managing plant flow

👩‍🌾 Year-round

It’s International Dark Sky Week ⭐🌙 A global celebration of the night and a reminder that darkness plays an essential role in the natural world.

From migrating songbirds like warblers and thrushes, to bats and owls that hunt at night, many species of insects, amphibians, and nocturnal mammals rely on natural darkness and light cycles to guide migration, breeding, and feeding.

Yet too often, outdoor lighting is overused and left on when it’s not needed, washing out the darkness and diminishing the natural cues wildlife depend on.

Good news is you can help with these outdoor lighting tips from DarkSky International:
• Use outdoor light only when it’s needed
• Direct light only where it’s needed
• Keep light low and no brighter than necessary
• Use controls so light is only on when required
• Choose warm-coloured lighting to reduce blue light
