Comparing satellite maps from 2000 and 2020, the forest around Red Deer shrank from about 1,950 hectares to 1,860 hectares, a net loss of about 86 hectares (−4.4%). New forest grew on about 68 hectares, but 154 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.

Questions about Red Deer
What is the air quality (AQI) in Red Deer right now?
The latest reading for Red Deer shows an AQI of 19 (Good), observed Nov 10, 18:00 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 145 km, US EPA index. The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Red Deer today?
At AQI 19 (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 Red Deer been like this week?
Over the last 7 days, the CAMS air-quality model put Red Deer's daily AQI at 24 on average, from 6 on Nov 7 to an hourly peak of 59 on Nov 4. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Red Deer'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 Red Deer lost since 2001?
Since 2001, the area within 10 km of Red Deer has lost about 91 hectares of forest (about 130 football pitches): 4.5% of the forest it had in 2000. Most of it (64%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Red Deer shrank from about 1,950 hectares to 1,860 hectares, a net loss of about 86 hectares (−4.4%). New forest grew on about 68 hectares, but 154 hectares were lost.
What is the tree count in Red Deer?
Red Deer has an estimated 94,923 trees across the 12.33 km² of land measured — 30.8% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Red Deer need?
Red Deer has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Red Deer's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. 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 Red Deer; the tree count is an estimate derived from that cover.
