Where I live, poplar is a real problem as a field invader, since suckers pop up from the roots yards away from the main stem...and they can easily grow 2 or 3 feet tall in a season. Old fields tend to get lots of spruces, birches and (sometimes)alders (along with the poplars) around the edges.
We get our share of poplar too. Root suckers and they sprout from seed very well in full sunlight. Fortunately they aren't very tough trees. They snap off if you double them over by hand up to about 1" diameter and what's left standing rots quickly. Looks goofy.
