Comparing satellite maps from 2000 and 2020, the forest around Brampton grew from about 4,130 hectares to 4,480 hectares, a net gain of about 349 hectares (+8.4%). New forest grew on about 471 hectares, while 122 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.

At AQI 22 (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 Brampton been like this week?
Over the last 7 days, the CAMS air-quality model put Brampton's daily AQI at 27 on average, from 14 on Nov 9 to an hourly peak of 53 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Brampton'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 Brampton lost since 2001?
Since 2001, the area within 10 km of Brampton has lost about 56 hectares of forest (about 79 football pitches): 2.6% of the forest it had in 2000. Most of it (82%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Brampton grew from about 4,130 hectares to 4,480 hectares, a net gain of about 349 hectares (+8.4%).

How many more trees does Brampton need?
Brampton has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Brampton's air quality and tree cover measured?
