Renewable isn't really accurate for wood, at least not in human time scales. A maple takes about 25 years to mature. It's about three maple trees to a cord.

Renewable isn't really accurate for wood, at least not in human time scales. A maple takes about 25 years to mature. It's about three maple trees to a cord. Assuming 5 cords per winter, we're talking 375 trees before the first tree cut can be reharvested (assuming it was replanted immediately). That doesn't into account soil depletion and carbon release.
