I live in west texas, and we have no only an abundant supply of oil and strip clubs, we also have one thing that while is rarely used on guitars, is very stable and has the least shrink/swell when exposed to humidity.
Mesquite
There are literally millions of them around here, no one gives a rats ass if you cut them down, and more importantly, it's very easy to work with.
I cut a tree down today and thought I would see how well it milled, I was hoping to get a fretboard blank out of it but alas that was a no go, I did however get a good knack for working it and it planes out gorgeously.
The only con, it can be full of knots, you have to cut down thick branches or the huge middle stump and hope there are no knots. You can see a full on here, but I knew there would be on this as it had branches coming out of it. You can see it has a beautiful contrasting color and interesting grain patterns.
And with just one knot like that one on the left in the last image, if the board has some wiggle room on the length, you could position it so it's covered up by a 5th or 7th fret inlay.
