Deforestation · 2001–2025
Which country has lost more forest, Turkey or United States?
United States has lost more: about 126 million acres (51 million ha) of forest from 2001 to 2025, against 843,000 ha in Turkey, or 60 times as much. 9.87 million acres (4 million ha) of United States's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2021, with 79,200 ha lost.
Worst year: 2004, with 6.77 million acres (2.74 million ha) lost.

Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 95 in Turkey and 308 in the United States, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. United States rests on 308 cities against 95, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Turkey vs United States: your questions answered
Is United States cleaner than Turkey?
On air quality, yes, right now: United States's cities average AQI 38 against 77 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather. At ground stations alone, which measure rather than estimate, the averages are Turkey 81 (67 cities) and United States 40 (281 cities).
Which country has lost more forest, Turkey or United States?
United States has lost more: about 126 million acres (51 million ha) of forest from 2001 to 2025, against 843,000 ha in Turkey, or 60 times as much. 9.87 million acres (4 million ha) of United States's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, Turkey or United States?
United States does: its measured cities average 25.1% tree cover against 14.2%, a gap of 10.9 percentage points.
How many cities are the Turkey and United States figures based on?
95 measured cities in Turkey and 308 in the United States. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Why are there two air quality averages for each country?
The first covers every measured city, using a ground station where one is close and a model estimate everywhere else. The second counts only cities with a current station reading, which is measured rather than estimated but covers fewer places. Airleaf's world rankings use the station figures only.
Does this cover the whole of Turkey and the United States?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
