Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

- Overall change
- +147 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Liverpool grew from about 1,250 hectares to 1,400 hectares, a net gain of about 147 hectares (+12%). New forest grew on about 184 hectares, while 36 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 Liverpool
What is the air quality (AQI) in Liverpool right now?
The latest reading for Liverpool shows an AQI of 31 (Good), measured Nov 11, 14:00 local time by the Wirral Tranmere, United Kingdom ground monitoring station, 3.2 mi (5.1 km) away, via OpenAQ. The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Liverpool 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 Liverpool been like this week?
Over the last 7 days, the CAMS air-quality model put Liverpool's daily AQI at 63 on average, from 30 on Nov 4 to an hourly peak of 89 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Liverpool'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 Liverpool lost since 2001?
Since 2001, the area within 10 km of Liverpool has lost about 7 hectares of forest (about 10 football pitches): under 1% of the forest it had in 2000. The biggest cause was towns and roads (30%). About 2 hectares (30%) was deforestation: forest cleared for good for farms, mines or towns. Comparing satellite maps from 2000 and 2020, the forest around Liverpool grew from about 1,250 hectares to 1,400 hectares, a net gain of about 147 hectares (+12%). New forest grew on about 184 hectares, while 36 hectares were lost.
What is the tree count in Liverpool?
Liverpool has an estimated 36,109 trees across the 4.3 sq mi (11.2 km²) of land measured — 12.9% tree cover, 17 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Liverpool need?
Liverpool needs roughly 47,866 more trees to close a 17-point shortfall against its 30% tree-cover target — about 1,053 t of extra CO₂ absorbed per year once grown.
How are Liverpool's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Liverpool, 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 Liverpool; the tree count is an estimate derived from that cover.
