Partial logging was introduced to E. delegatensis forests at altitudes over 600 m in Tasmania to reduce the incidence of high altitude growth check. Experiments showed that whilst the initial stocking of regeneration increased with basal area of stems retained, later aged stocking and growth of regeneration could be severely depressed by the retention of basal area in excess of 12 sq m per ha. In general, the basal area should be reduced to the lowest level capable of providing the requisite protection and ensure full stocking. This figure can be expected to vary between 12 and 16 sq m per ha. These results have been incorporated into operational prescriptions for this forest type.
