They are here in Vermont. When a woodlot gets cut, high grade gets sawn for lumber, stuff that doesn't make the cut for saw logs but can be pulped becomes paper and stuff that doesn't work for either of the above becomes firewood. There may be some variation based on pricing any given day, but my understanding is that this is pretty common when harvesting mixed forest (as opposed to a monoculture forest). We got three cords delivered last year that was mostly black birch, red oak, and white ash, and we burned two, supplemented by propane that kept the overnight low around 50F/10C inside. Our hot water, incidentally, is tankless propane.
