Tulip Poplar like a few others said. The only downside is that it throws sparks. It seems every time a red oak or hickory uproots on my cutting grounds it body slams a poor little tulip poplar on the way to the ground. The lightweight rounds are definitely welcomed after wrestling oak rounds over a rocky, hilly landscape.
It's all Silver Poplar. I fall it in the winter. Leave it lie over the summer. It leaves out and the leaves live most of the summer. Sucking the moisture out of the tree. Then in the fall I go log it. Often I do the falling on snowshoes. But wait till after a hard frost to go get it. Keep the yellow jackets in their beds.
It is elm here. I don’t mind it. Splitter eats it up and as long as you season it proper there are no issues. I won’t go looking for it but won’t turn my nose up either.
