Narrow Poplar Canopies

In the same vein that Spruce trees can grow with a unique Pine tree canopy, and how there is a Old Growth Taiga dedicated to them, I think that making the autumn tree a poplar presents the opportunity to give it a more columnar variant canopy, as it would give another shape for people and the world gen to play with. With this, their could be two variants of the dappled forest biome, with the currently projected one being called the Dappled Maple Forest, and then having the regular Dappled Forest feature the Narrower trees.
