Calgary continues efforts to plant nearly a million trees, and better balance local canopy

After a major influx of federal dollars last fall, Calgary's efforts to plant more trees continues this spring.

Since 2023, Calgary has planted 200,000 trees as part of an effort to introduce 930,000 in total by 2029. Looking further ahead, Calgary, a city of roughly seven million trees, aims to nearly double its urban canopy coverage from 8.25 per cent, as measured in 2022, to 16 per cent by 2060.

The local effort was bolstered by nearly $61 million from the federal government last fall. The funding is part of Canada's 2 Billion Trees program, a national effort to improve urban spaces, provide cleaner air and help the country adapt to climate change.

But where Calgary's new trees will go is a pressing question surrounding this project.

Many of the more well-established and central Calgary neighbourhoods have more trees. But Calgary's canopy often grows more sparse in neighbourhoods further from the city's core, in areas that weren't developed with trees in mind or have poorer soil quality.

The disparity creates a problem for residents who miss out on benefits like trees that offer shade to mitigate heat in the summer and disrupt winds to protect from the cold in the winter, while also more effectively managing storm water, improving biodiversity, and enhancing social and mental wellbeing.

Paul Atkinson, the city's acting urban forestry lead, said Calgary tries to tackle this disparity by targeting areas with less trees per hectare of public land, but it's not always a simple fix. Some areas need soil rehabilitation, which can be expensive, while other neighbourhoods weren't developed with enough space for trees, based on street design and where utilities were installed.

"If you take that bird's eye view and look at some of these sites, they might look like ideal spots to plant a tree, but they might actually have high-pressure gas lines or utilities or street light cables or all these things underground," Atkinson said in an interview with This Is Calgary.

A map of the city's urban canopy shows neighbourhoods like Eau Claire, Erlton and Garrison Green have more than 25 city-maintained trees per hectare. But other neighbourhoods like Franklin, Sunridge and Mayland have less than five.

The city's efforts don't just end on public land though, as its Branching Out program offers roughly 5,000 trees per year for residents to grow on their land, with quadrants covered by less canopy given priority.

But some parts of the city want a stronger effort to balance the scales between trees in each neighbourhood.

Much of Ward 5, which is represented by Coun. Raj Dhaliwal, has an urban canopy far below the city's average. In November, Dhaliwal said he planned to call for a sizeable amount of the federal funding toward new trees to be used in his ward.

Saddle Ridge is one neighbourhood with less coverage, boasting just eight city-maintained trees per hectare.
