Comparing satellite maps from 2000 and 2020, the forest around Solihull grew from about 4,280 hectares to 4,700 hectares, a net gain of about 417 hectares (+9.7%). New forest grew on about 510 hectares, while 94 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 Solihull
What is the air quality (AQI) in Solihull right now?
The latest reading for Solihull shows an AQI of 67 (Moderate), measured Nov 11, 15:00 local time by the Birmingham A4540 Roadside, United Kingdom ground monitoring station, 5.8 mi (9.4 km) away, via OpenAQ. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Solihull today?
At AQI 67 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Solihull been like this week?
Over the last 7 days, the CAMS air-quality model put Solihull's daily AQI at 66 on average, from 30 on Nov 4 to an hourly peak of 95 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Solihull'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 Solihull lost since 2001?
Since 2001, the area within 10 km of Solihull has lost about 31 hectares of forest (about 43 football pitches): 1.1% of the forest it had in 2000. The biggest cause was towns and roads (33%). About 14 hectares (44%) was deforestation: forest cleared for good for farms, mines or towns. Comparing satellite maps from 2000 and 2020, the forest around Solihull grew from about 4,280 hectares to 4,700 hectares, a net gain of about 417 hectares (+9.7%). New forest grew on about 510 hectares, while 94 hectares were lost.
What is the tree count in Solihull?
Solihull has an estimated 152,681 trees across the 4.9 sq mi (12.57 km²) measured — 48.6% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Solihull need?
Solihull has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Solihull's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Solihull, 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 1.2 mi (2 km) radius around Solihull; the tree count is an estimate derived from that cover.
