Comparing satellite maps from 2000 and 2020, the forest around Sutton Coldfield grew from about 4,370 hectares to 4,940 hectares, a net gain of about 570 hectares (+13%). New forest grew on about 636 hectares, while 66 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 Sutton Coldfield
What is the air quality (AQI) in Sutton Coldfield right now?
The latest reading for Sutton Coldfield shows an AQI of 31 (Good), measured Nov 11, 15:00 local time by 3 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Birmingham A4540 Roadside, United Kingdom, 6.7 mi (10.8 km) away). The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Sutton Coldfield today?
At AQI 31 (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 Sutton Coldfield been like this week?
Over the last 7 days, the CAMS air-quality model put Sutton Coldfield's daily AQI at 66 on average, from 30 on Nov 4 to an hourly peak of 97 on Nov 8. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Sutton Coldfield's AQI the same as the UK's Daily Air Quality Index?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. The UK's Daily Air Quality Index (DAQI), published by Defra, runs from 1 to 10: 1–3 low, 4–6 moderate, 7–9 high and 10 very high. It is a different scale altogether, so a US AQI figure can't be read on it directly; both, though, are built from the same main pollutants, with fine particles (PM2.5) usually the one that decides the reading.
How much forest has the area around Sutton Coldfield lost since 2001?
