I can't help with exact numbers, but I can tell you that trees actually put out less O2 than grasslands do. Reforestation efforts in the US have gone so far that we now have more trees than we did at the time of our nation's founding. As a result our land's total efficiency in converting CO2 into O2 has decreased. We would actually be better off with more grassland than forest! Strictly from an O2 production standpoint that is. :-) Later, Matt -- Composed on "Ti", my Titanium PowerBook G4.
