By protecting the natural environment, that is, its trees which function as natural infrastructure Nanaimo’s tree canopy saves the city $13.7m a year. This is an estimate of the value of the work trees do that would otherwise have to be paid for, from cleaning the air to absorbing stormwater and providing shade and cooling in hot weather.
This is a virtuous circle in which “The health of our environment directly contributes in a positive economic way to the sustainability of our city” stated one councillor. The more land that the city acquires, the more trees are planted and protected, the larger the tree canopy grows which in turn saves the city more money.
Sadly, that is not the attitude in Qualicum Beach which with the exception of Eaglecrest, we are not planting any trees, or designating more parkland. In the end, at some point a bill will come in to pay for what we could have had for free, natural infrastructure to protect us.

Nanaimo’s tree canopy saves the city an estimated $13.7 million a year in avoided infrastructure, according to a new assessment presented to a council committee last week.
That’s an estimate of the value of the work trees do that would otherwise have to be paid for, from cleaning the air to absorbing stormwater and providing shade and cooling in hot weather.
When it comes to stormwater, trees can reduce runoff and soil erosion and improve water -quality, especially when strategically planted, says the city-commissioned report, which was done in conjunction with Colorado-based urban forestry consultant PlanIT Geo Inc. and presented to the city’s governance and priorities committee meeting.
The dollar value of carbon sequestration alone — around 31,500 tons annually — was estimated at $367 million, and was assessed by looking at what it would cost to mitigate the impact of that carbon if it was released and not bound up in trees.
A canopy is the layer of branches and leaves at the top that shelters the ground from above. In this case, a tree canopy refers to the land covered by trees over 10 feet tall.
The report says that in 2025, Nanaimo’s trees covered almost 39 per cent of the city’s private and public land, up from the 33 per cent in 2016.
Much of the canopy increase came from growth of already-existing trees, but some was from new trees.
“I was really surprised by that one, obviously, because we’re an urban area and our ¬reason for being, a lot of the time, is around growth and supporting growth in our region,” said Charlotte Davis, the city’s deputy director of parks and natural areas.
The report notes that development has put pressure on the existing canopy. Over that same time period, development caused the loss of tree canopy totalling about 84 soccer fields.
Putting the benefits of the tree canopy into an actual dollar value was useful, Coun. Hilary Eastmure said.
“Sometimes people just need to see the numbers associated with what we actually mean when we say the environment and the economy are intrinsically linked,” she said.
“The health of our environment directly contributes in a positive economic way to the sustainability of our city.”
Eastmure also pointed to the report’s finding that city-owned properties contain 19 per cent of Nanaimo’s urban forest, saying it emphasizes the direct role of the city in managing the health of its forest.
“That speaks to the need to continue to acquire more park land, and protect the trees that we have,” she said.
The report also highlighted the more than 500 trees in Nanaimo that are taller than 30 metres, and pointed out a few of special interest.
One is a 63-metre ¬Douglas fir growing in Westwood Ravine Park that the report noted is “as tall as The Pacifica ¬condominium complex in ¬downtown.”
Others include a 41-metre Douglas fir beside the playground in Mansfield Park, and a 35-metre Douglas fir in Comox Park that reaches above the rooftops of the houses around it.
Cities should aim for a tree-canopy cover of at least 30 per cent or higher, the report notes. Some parts of the city, such as the downtown core and many roadways, currently have less than 20 per cent tree-canopy coverage.
“Our goal is for every neighbourhood within the city of Nanaimo to have 30 per cent canopy coverage,” said Davis.
