Based on what lore I've seen, that would seem to be the case. In the level 35 WHM quest, the questgiver notes that the trees and the elementals are one and the same. I think it's likely that the notably higher activity of the elementals of the Shroud compared to other locations is due to the high concentrations of Aether there, but that's purely speculation on my part.
