Calgary’s Urban Forest: A Vital Resource for Our Community
As we shake off the inconvenience of a late spring snowfall, let’s take a moment to appreciate the benefits of this unexpected moisture—especially for Calgary’s trees.
With approximately 7 million trees valued at over $1.3 billion, our city’s urban forest is impressive, given our dry climate, poor soil conditions, and extreme weather. However, Calgary’s tree canopy covers only about 8% of the city, far behind Edmonton’s 13%, Winnipeg’s 17%, and the 20%+ coverage found in many other urban centres. Our city’s sprawling nature means we need even more trees to achieve a healthier canopy.
Why More Trees Matter
Despite the challenges, increasing Calgary’s tree coverage is critical, especially in the face of climate change. Trees provide numerous benefits that enhance urban life, including:
• Cooling Our City: Trees reduce the urban heat island effect by providing shade and releasing moisture, which helps lower temperatures and decrease energy consumption.
• Improving Air Quality: Trees act as natural air filters, absorbing pollutants and improving respiratory health for residents.
• Managing Stormwater and Preventing Flooding: Trees help absorb excess rainwater, reducing runoff and lowering the risk of flooding.
• Supporting Wildlife and Biodiversity: A well-maintained tree canopy provides essential habitats for birds, pollinators, and other wildlife.
• Boosting Mental and Physical Well-Being: Green spaces have been linked to reduced stress, increased physical activity, and improved community well-being.
How You Can Help
Homeowners play a crucial role in expanding Calgary’s urban forest. Here’s how you can contribute:
1. Plant the Right Trees
Choosing the right species is key to ensuring tree survival in our climate. Consider hardy, drought-resistant trees such as:
• Saskatoon Berry – A shrub that produces edible fruit.
• Colorado Blue Spruce – A resilient evergreen.
• Bur Oak – A sturdy, drought-tolerant tree.
• Mountain Ash – A winter-hardy option with bright berries.
2. Diversify Tree Species
A mix of deciduous and evergreen trees enhances biodiversity and makes Calgary’s tree canopy more resilient to disease and pests.
3. Practice Proper Tree Care
• Watering: Young trees need consistent watering, especially during dry periods.
• Mulching: Helps retain moisture and enriches soil health.
• Pruning: Encourages healthy growth and prevents damage.
• Fertilizing: Can support young trees in their early years.
4. Protect Trees from Harsh Conditions
• Winter Protection: Wrapping trunks and shielding trees from Chinook winds can prevent damage.
• Soil Care: Aerating the soil and adding organic compost helps promote strong root systems.
5. Get Involved in Community Initiatives
Support local tree-planting efforts and programs such as the Calgary Urban Forest Alliance or municipal initiatives like Green Calgary. Many organizations offer free or discounted trees to encourage planting.
6. Advocate for More Trees in Your Neighbourhood
Encourage neighbours, attend city meetings, and support urban forestry policies to help make tree coverage a priority in Calgary.
A Greener Future for Calgary
Trees are more than just a scenic addition to our streets; they are an essential component of a sustainable and resilient city. By planting and caring for trees, we can help mitigate climate change, improve public health, and enhance the beauty of our community. Let’s work together to grow Calgary’s urban forest for future generations!
