You are confusing short-rotation trees (hybrid poplars, for example)
with longer term, but still not old-growth, trees. These medium-term
tree farms may have trees grow for twenty years or more before
harvest. If you ever drive in Florida along the bend between the
panhandle and the penisula, you'll pass these tree farms for hours.
