Deforestation · 2001–2025
How much forest has Newport lost?
Since 2001, the area within 10 km of Newport has lost about 450 hectares of forest (about 630 football pitches): 11% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. Almost none of it was deforestation, meaning forest cleared for good.

- −123 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Newport shrank from about 4,500 hectares to 4,380 hectares, a net loss of about 123 hectares (−2.7%). New forest grew on about 266 hectares, but 390 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 Newport
What is the air quality (AQI) in Newport right now?
The latest reading for Newport shows an AQI of 62 (Moderate), measured Nov 11, 15:00 local time by the Newport ground monitoring station, 1.3 mi (2.1 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 Newport today?
At AQI 62 (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 Newport been like this week?
Over the last 7 days, the CAMS air-quality model put Newport's daily AQI at 68 on average, from 42 on Nov 5 to an hourly peak of 86 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Newport'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 Newport lost since 2001?
Since 2001, the area within 10 km of Newport has lost about 450 hectares of forest (about 630 football pitches): 11% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. Almost none of it was deforestation, meaning forest cleared for good. Comparing satellite maps from 2000 and 2020, the forest around Newport shrank from about 4,500 hectares to 4,380 hectares, a net loss of about 123 hectares (−2.7%). New forest grew on about 266 hectares, but 390 hectares were lost.
What is the tree count in Newport?
Newport has an estimated 70,990 trees across the 4.7 sq mi (12.24 km²) of land measured — 23.2% tree cover, 7 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Newport need?
Newport needs roughly 20,807 more trees to close a 7-point shortfall against its 30% tree-cover target — about 457.8 t of extra CO₂ absorbed per year once grown.
How are Newport's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Baneswell, 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 Baneswell; the tree count is an estimate derived from that cover.
