Re: Tree protection zones| Critical root zones| Critical Root Radius| AUSTRALIA Generally with Eucs I'd place them in the poor tolerance to root damage/disturbance but its certainly fine to put a particular species that your experience tells you is moderately tolerant into that category. Providing the tree has not (to your knowledge) been damaged in the past the difference may not be critical, also remember that roots don't grow in symetrical circles evenly spaced so site specific soil/ground conditions play an important role here too TPZ or CRZ fencing can and should reflect any such anomalies...it can be to the great advantage of the long term health of the tree.
