It might be a surprise when looking at the stratification of the atmosphere, where winds can occur, the depth of the atmosphere, and how tiny trees are on that scale.

On one hand, the mechanism seems readily apparent. On the other, it's also astounding. It's not just that the trees create physical disruption with their own physical bodies, but also through how they modify the properties of the atmosphere above and around them. That's incredible. They transport immense amounts of water into the atmosphere.
