- Forest in 2000
- 1,280 ha

- Overall change
- +91 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Saint Peters grew from about 1,280 hectares to 1,370 hectares, a net gain of about 91 hectares (+7.1%). New forest grew on about 97 hectares, while 6 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.

What has the air quality in Saint Peters been like this week?
Over the last 7 days, the CAMS air-quality model put Saint Peters's daily AQI at 63 on average, from 36 on Nov 4 to an hourly peak of 82 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Saint Peters'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 Saint Peters lost since 2001?
Almost no forest has been lost around Saint Peters since 2001: less than 1 hectare of the 173 hectares there in 2000. Comparing satellite maps from 2000 and 2020, the forest around Saint Peters grew from about 1,280 hectares to 1,370 hectares, a net gain of about 91 hectares (+7.1%). New forest grew on about 97 hectares, while 6 hectares were lost.
What is the tree count in Saint Peters?
Saint Peters has an estimated 68,801 trees across the 4.9 sq mi (12.57 km²) measured — 21.9% tree cover, 8 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Saint Peters need?
Saint Peters needs roughly 25,447 more trees to close a 8-point shortfall against its 30% tree-cover target — about 559.8 t of extra CO₂ absorbed per year once grown.
How are Saint Peters'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 1.2 mi (2 km) radius around Broadstairs; the tree count is an estimate derived from that cover.
