CALGARY CLIMATE HUB LAUNCHES TREE EQUITY CAMPAIGN
The Calgary Climate Hub is launching its Tree Equity campaign with a Tree Equity Tool and a Tree Planting Guide.
CALGARY TREE EQUITY TOOL
Visit our Tree Equity Tool at https://calgarytreeequity.ca/
This valuable tool, created using open data sources, lets you:
- view the percentage of tree canopy in each community of Calgary,
- see the change in tree canopy over time,
- display a 'Tree Equity Score' which uses various socioeconomic indicators to help prioritize areas in need of increased tree canopy
Are you curious about the tree canopy in your neighbourhood? Try zooming in to see if the canopy in your community has been increasing or decreasing.
TREE PLANTING GUIDE

Our tree planting guide offers tips on how to properly plant trees and care for them. Find out what types of trees are best for Calgary and where you can buy them. Whether you're planting your own micro-forest in your backyard or looking for a more mature tree, this guide will help you figure it out and get it done.
What Is Tree Equity?
An analysis by Nature Canada in 2022 confirmed previous research that neighbourhoods with lower household incomes and larger BIPOC communities don't have as much access to trees and urban forests as wealthier and less culturally diverse communities. As the following map indicates, communities in northeast Calgary have less tree canopy than similarly aged communities in other parts of Calgary.
But new neighbourhoods in northeast Calgary are built on grasslands...
This is true, but did you know that heavily forested neighbourhoods like Mount Royal and Sunnyside were also built on grasslands? Now these neighbourhoods are over 100 years old, they've had a lot of time to grow mature trees. But that's not the whole story.
Both Mckenzie Lake and Taradale housing developments were built in the early 80's, but the McKenzie Lake neighbourhood has a 12% tree canopy while Taradale's tree canopy is only 2.7%. This is harder to explain and seems to be an example of an inequitable situation. Many trees were planted on public land around McKenzie Lake, but by contrast there were very few trees planted in the park surrounding Taradale Lake.
Why does it matter?
In the City of Calgary's Climate Strategy, a goal has been set to increase the city's average tree canopy from 8% to 16%. To be more fair, underserved communities should be receiving a lot more trees as Calgary Urban Forestry works to achieve the tree canopy target. Communities with low tree canopy deserve a more equitable share of trees.
There are many benefits to urban trees and forests, from providing cooler shade on increasingly hot summer days to attracting birds and pollinators. Trees combat the urban heat island effect by absorbing sunlight and releasing moisture to make the air feel cooler.
The tree leaves slow rainfall to reduce surge flooding during heavy rains and tree roots make the surrounding soil spongier, which absorbs and stores more rain water.
Trees are also known to filter the air and release aerosols that provide health benefits. Living among mature trees lowers your heart rate and blood pressure and increases the ability to recover from stress. In fact, a study in Portland covering 30 years of tree planting showed one premature death was avoided for every 100 trees planted. Trees save lives!!!
What can we do about it?
There are many reasons to plant trees and we shouldn't sit back and hope that the city decides to distribute trees more equally across all neighbourhoods. Communities can work with their city councillors to try and improve their share of trees planted each year. People can also take advantage of municipal tree planting initiatives or plant low cost seedlings on their property and watch them grow! It's up to all of us to pitch in and plant more trees and tiny forests in our communities and in our yards.
The Calgary Climate Hub will be holding a series of workshops to share ideas on how to bring more trees to your neighbourhoods. Watch for upcoming workshops on our Events page.

Remember, Calgary average tree canopy coverage is 8%, but it is far from evenly distributed.
