Question:
What plant or tree produces the most o2 in North America?


Replies:
I am not aware of a single book or website naming any one plant species. However, one can make some approximate guesses for vegetation types. Generally fast-growing plants have high photosynthetic rates, and thus, produce more oxygen.

In warm regions such as Florida, one can guess evergreen tropical/subtropical trees such as palms. In cold regions such as much of Canada, one can guess coniferous evergreen trees of the boreal forest such as spruce and fir, but these have generally low photosynthetic rates. For the regions in between, one could guess widespread, fast-growing trees such as deciduous poplars or evergreen pines, and even fast-growing grasses of prairies and lawns.

In the waters of lakes, estuaries, and coastal waters, one could guess fast-growing seaweeds, among which unfortunately include invasive exotic species.

Hope this is of some assistance.
