I would start from something like: total area of area covered by 


landuse=forest and natural=wood 


after excluding very small areas.

Depends on (a) where (b) what kind of accuracy is needed, forest in many regions

are unmapped or partially mapped.

What you exactly want to find?

No, you cant. As there are conflicting tagging methods 


natural=wood, landuse=forest, landcover=trees are effectively synonymous.
