Do you mean they don't have too many types of wood there?
When you use (glue) different types they may warp, unless you make a sandwich.
Note: Also, I was thinking in good wood from old buildings (villas) like the planks from the stairs (and wide-plank flooring & windows, old and well dry) sometimes in exotic wood. Sometimes you may have a second resource beside new wood. They are now using old wine casks for speakers, recycled.
