Sustained yield, stand structure, and non-wood options after 110 years of logging in a New South Wales blackbutt forest [Eucalyptus pilularis; review]
1992

Although more than 1 million cu m of timber were harvested from the Kendall Management Area on the north coast of New South Wales over the period 1960 to 1990, indications are that the standing log volume in 1990 had not changed significantly from that standing in the same area in 1960. Thus, in gross terms, growth has balanced harvest over the whole forest in the recent 30-year period. However, there are indications that the forest was overcut prior to 1960. Changing markets and community attitudes suggest that some adjustments to the 'ideal' stand structure are warranted. An increase in the stocking density of the smaller trees to allow for increases in thinning for smallwood products, and an increase in the stocking density of the largest trees (greater than 100 cm dbhob) to provide for arboreal wildlife are recommended. Management decisions to realise some options to retain many non-wood values (particularly wildlife) will need to be made in the near future, preferably within the next 2 cutting cycles.
