Sri Lanka as a whole

34.4% of Sri Lanka was forested as of 2024, against a 30% benchmark. That already clears the benchmark — the city reports above show where cover is still thin locally. Source: World Bank (FAO).

Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
