I burn it
My generic rule of thumb is if I have to touch it, I burn it. I burn every species here. Got a lot of willow down in the swamp pastures and if branches fall off of them where I have to mow, I buck them up, split them, and they get mixed into the pile.
Fifty feet from your woodshed? Cut it split it stack it, but be sure to get other wood as well. That tree might last you several years for fast morning wood and for "shoulder season" wood.
I look at the wood piles areas. Do I want to see cut and split stacked there, no matter what it is, or *air*? I have the space and the opportunity, so I am the anti wood snob. If all I had was a tiny lot with very little room and had to go drive miles and miles to go get wood, no, I'd go for the better species gusto. But free right at your house, sure, you can burn it, it is just not much heat per cubic volume. Wood has similar heat/ BTUs per *dry seasoned weight* though. A ton of dry willow got similar BTUs to a ton of oak. By the cord, no, by the ton, yes.
