Rosewood trees have been placed on the CITES endangered list, which means trading vintage guitars across some borders requires a certificate or will be restricted. The effect on new guitars and makers is also evident by their gradual shift away from some traditional tonewoods. Taylor for example is growing plantations of maple with selected figurative grain to use in future guitar designs – maple being under far less logging pressure than tropical hardwoods. Both conservation of the forests and a cultural shift (with guitar gear heads) needs to continue. Necessity is the mother of invention in this case.
