I was asked recently how much oxygen is contributed to the atmosphere on a 
yearly basis by the average tree.  I have found considerable information on 
CO2 uptake by single species and by areas of forest; however, an answer to 
the oxygen question eludes me.  I know I have seen some sort of an answer 
in the popular press.  This is not an easy question to answer because trees 
differ by species, age, site conditions, geographic location, etc., etc.  
However, if anyone can provide any sort of answer, I would be most 
appreciative.
