Vancouver forests become a line in the city budget
Treating the tree canopy as infrastructure rather than amenity changes who maintains it, who funds it, and what happens when it fails.

Parks departments have always known the canopy does work: shade, stormwater retention, cooling. What has changed is that the work now has a number attached, and the number sits in the capital budget beside culverts and pumps.
The reclassification
Once trees are infrastructure, they get an asset register, a condition survey, and a replacement schedule. They also get compared, unsentimentally, against grey alternatives — and in dense catchments the canopy wins on cost per litre retained.
That comparison is what unlocked the funding. A parks budget competes with libraries and community centres. A stormwater budget competes with pipes, and against pipes the canopy is cheap.
An asset with a maintenance budget outlives an amenity with a volunteer group.
What it funds
Steady arboriculture rather than planting campaigns.
The unglamorous finding across several cities is that survival rates, not planting totals, determine canopy cover a decade out. A tree planted and abandoned has perhaps even odds of reaching maturity; the same tree watered through years two and three does far better, and watering is a labour line rather than a capital one.
Planting announcements are photogenic and cheap. Watering is neither, which is why the asset framing matters: an asset register creates an obligation to maintain, and an obligation is harder to defund than an aspiration.
The equity question
Canopy maps track income maps almost everywhere, and a maintenance-led budget risks entrenching that — well-treed districts have more asset to maintain, so they get more of the maintenance budget.
Two councils have responded by weighting the replacement schedule toward deficit areas, which means deliberately spending less than the asset condition would justify in the leafy districts. That is politically durable only while nobody in those districts loses a mature street tree.
What to watch
Watch three-year survival rates rather than planting announcements. Watch whether the asset register is published. And watch how the deficit weighting survives its first budget squeeze, since it is the line most easily presented as neglect.
