Comparing satellite maps from 2000 and 2020, the forest around Huddersfield stayed about the same size, at about 5,790 hectares: new forest grew on about 153 hectares, and about 61 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 Huddersfield
What is the air quality (AQI) in Huddersfield right now?
The latest reading for Huddersfield shows an AQI of 27 (Good), measured Nov 11, 14:00 local time by the Leeds Centre, United Kingdom ground monitoring station, 14.5 mi (23.3 km) away, via OpenAQ. The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Huddersfield today?
At AQI 27 (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 Huddersfield been like this week?
Over the last 7 days, the CAMS air-quality model put Huddersfield's daily AQI at 58 on average, from 23 on Nov 4 to an hourly peak of 93 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Huddersfield'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 Huddersfield lost since 2001?
Since 2001, the area within 10 km of Huddersfield has lost about 92 hectares of forest (about 130 football pitches): 1.4% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 15 hectares (16%) was deforestation: forest cleared for good for farms, mines or towns. Comparing satellite maps from 2000 and 2020, the forest around Huddersfield stayed about the same size, at about 5,790 hectares: new forest grew on about 153 hectares, and about 61 hectares were lost.
What is the tree count in Huddersfield?
Huddersfield has an estimated 107,757 trees across the 4.9 sq mi (12.57 km²) measured — 34.3% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Huddersfield need?
Huddersfield has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Huddersfield's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Huddersfield, 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 Huddersfield; the tree count is an estimate derived from that cover.
