No. The pure reason why some areas (with a particular set of meteorological and soil conditions) nurture trees (and establish themselves as stable forests) is because they are in general more efficient photosynthesizers (on a spatial basis) in that area. That is just pure survival of the fittest. To validate my claims, isolating "plants" from the whole ...
