How much forest has Chihuahua lost?
There was almost no forest around Chihuahua in 2000, so there has been almost nothing to lose since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

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.
