Tough to tell, what glue? Some glues dissolve in DNA, some don't. What glue?
As for specie, I wouldn't try to guess from a web-photo, too many wood look too similar.
As for drying DNA is a crap-shoot, actual tests by Forest product types show that they can get wildly different results from the same specie of wood. That's what it's used by hobbies and not commercial production.
