Worst year: 2021, with 6.49 million ha lost.
Worst year: 2023, with 230,000 ha lost.

Behind the averages
The cities behind Russia and Tanzania
An average says nothing about how far apart the best and worst places are. These are the measured cities at each end.
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: 168 in Russia and 34 in Tanzania, 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. Russia rests on 168 cities against 34, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.

Does this cover the whole of Russia and Tanzania?
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.
