This table is a bit suspect. It might be showing Appalachian oak for red oak, which is much less dense than pin oak or other red oaks. I can assure you that dry mulberry, for example, is not as dense as dry pin oak. However, this table shows a cord of dry mulberry outweighing red oak. In my neck of the woods, that's just not true.
I'd love to ship this guy a truckload of 2 to 3-year old red oak from a 110 year-old tree that I just split and let him rerun his analysis.
And I would love to ship a cord of 200 year old sugar maple from my area or further north.
The oaks I find just don't burn right, they coal and last forever and throw higher/medium heat.They leave a ton of coals for the morning though.
Re oak will cure in a year, white/burr I'm not sure if it ever does.
Beech does well but doesn't last, yellow birch does better than the btu charts show and I'm disappointed in the ash species.Low heat and no coals.Splits as hard as elm but better heat and coals plus a nice fragrance.
I've only burnt Black locust once and it spit and sputtered and popped but threw good heat but was like beech, 3 hours later its almost dust.
Lots of locals burn and like Red Maple aka swamp maple aka soft maple. It splits easy, almost no ash,plentiful,cheap, and if you cut on a swamp you don't have to clean up the brush because its gone when the ice melts. starts nicely and if your home to keep jamming the stove, it throws a decent amount of heat. Not many coals though.
You also never have to sharpen a chain more than once a week cutting on ice.
Ironwood/hop hornbeam is the ultimate wood in this area, lasts long, has more btu's per pound than soft coal and leaves a decent amount of coals in the morning.
The only problem with it is it takes about 8 hours to cut and collect a cord because it only grows to 8" dbh 35 feet tall with most trees 6 inch.
Its been suggested a full diet of this stuff will warp a stove baffle plate.
The only Hickory we have is smooth bark or bitternut. It burns and works up good, It just hasn't jumped out at me with superb burning qualities.I wouldn't refuse it though.
With 20 years of burning under my belt and 500ish cords cut and split and sold I have found that the best combination on a cold winter night is 3 hard maple with one piece of red oak for coals.
But if the truth be known I will burn just about anything that falls on the property even basswood but I would get picky if i was paying for it.
