Deforestation · 2001–2025
How much forest has Borno State lost?
There was very little forest in Borno State in 2000, about 42 hectares, and about 28 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.
