(1) During the period 2004 to 2012 the average age of stands  regenerated since 1967 that were first thinned was 30 years.
(2) (a) Silvicultural records are maintained on a calendar (rather than financial) year basis to meet reporting requirements under the Forest Management Plan (FMP) 2004-13. During the 2012 calendar year approximately 586 hectares of regrowth karri regenerated since 1967 was thinned.
(b) The total removals recorded from areas of regrowth karri forest  regenerated since 1967 and thinned during 2012 was 72,711 cubic  metres. This includes 2,579 cubic metres of yellow stringybark  (Eucalyptus muellerana) logs.
(c) (i)  244 cubic metres
(ii) 69,888 cubic metres
(d) (i) A total of 2,020 cubic metres were estimated to be available. Note that the total removals recorded for 2012 is adjusted by the difference between the volume estimated and the actual removal in (c) (i) when monitoring to the allowable cut under the FMP 2004-13.
(ii) 55,928 cubic metres
