Comparing satellite maps from 2000 and 2020, the forest around Winnipeg grew from about 2,240 hectares to 2,370 hectares, a net gain of about 127 hectares (+5.7%). New forest grew on about 210 hectares, while 84 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

Frequently asked
Questions about Winnipeg
What is the air quality (AQI) in Winnipeg right now?
The latest reading for Winnipeg shows an AQI of 16 (Good), measured Nov 11, 07:00 local time by 2 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Winnipeg Ellen St., Manitoba, Canada, 1.5 km away). The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Winnipeg today?
At AQI 16 (Good): a good day to be active outside. Windows: open them to air the house. Masks: not needed. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Winnipeg been like this week?
Over the last 7 days, the CAMS air-quality model put Winnipeg's daily AQI at 22 on average, from 6 on Nov 10 to an hourly peak of 69 on Nov 5. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Winnipeg's AQI the same as Canada's AQHI?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Canada's Air Quality Health Index (AQHI), from Environment and Climate Change Canada, runs from 1 to 10 and above: 1–3 low risk, 4–6 moderate, 7–10 high and over 10 very high. It combines ozone, nitrogen dioxide and fine particles into one health-risk number, so it isn't a converted AQI, and the two can move differently, especially in wildfire smoke.
How much forest has the area around Winnipeg lost since 2001?
Since 2001, the area within 10 km of Winnipeg has lost about 85 hectares of forest (about 120 football pitches): 5% of the forest it had in 2000. Most of it (89%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Winnipeg grew from about 2,240 hectares to 2,370 hectares, a net gain of about 127 hectares (+5.7%). New forest grew on about 210 hectares, while 84 hectares were lost.
What is the tree count in Winnipeg?
Winnipeg has an estimated 92,232 trees across the 11.87 km² of land measured — 31.1% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Winnipeg need?
Winnipeg has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Winnipeg's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Legislature, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Legislature; the tree count is an estimate derived from that cover.
