Answer
Change the bark to children's playsand.  Most semi-arid and desert reptiles enjoy digging and would appreciate sand.  Bark is not the best substrate since it molds easily and can cause impaction if bits are accidently ingested.  Sand is also easier for poop removal, you can see it easier and can remove it right away.  The sand will also be easier to reform, as she digs happily it does fall back a bit.
