I don't know of any adaptations shown by bark.  Variation in bark character=
 is one of god's gifts to botanists.

Eucalyptus trees show great variation within a locality: gums, boxes,=
 stringybarks, peppermints and iron-barks can all grow close together,=
 though they are different species of course.  Conversely, one type of bark=
 can be found in very different environments - again on different species.
