In regards to evergreens and deciduous trees, which would put out more oxygen? It seems to me that the evergreens would due to the fact that they remain green year round and the ratio of needles to leaves is much greater.

On the other hand, remember rates of photosynthesis, and relative growth rates. Perhaps tropical and subtropical evergreen trees in first place, then maybe fast-growing temperate deciduous trees such as poplars, and then fast-growing southeastern conifers/pines.
