Strips of retained forest are used to aid fauna conservation in State Forests in several mainland states. Their use has often been justified in terms of maintenance of animal movement and they are thus referred to as wildlife corridors. I argue that it is unlikely that strips of retained forest will be important for movement in large tracts of production forest However, if these retained strips are set out so as to fully sample fauna habitat, I believe that, when used in conjunction with other measures, they will play an important role for fauna conservation. Research into the value of retained strips 100 m in width in Tasmania has commenced.
