Future national wood supply

H.H. Levack

New Zealand's existing forest estate and land suitable for new afforestation are described. Forest development alternatives are discussed in terms of possible eventual steady state yields and the times taken to reach them. Attention is drawn to the fact that even if no more new exotic afforestation is prescribed, annual exotic roundwood removals could rise to a steady 17.6 million m3/year, about twice the current rate, within 15 years from now.
The consequences of following current forestry management intention in New Zealand are described in terms of changes in stocked exotic forest area; changes in the rates of exotic and indigenous roundwood removals; changes in the rates of new planting, restocking, tending, utilisation thinning and clearfelling; changes in the log quality, species, and the geographic distribution of roundwood removals; changes in the type of logging system and forest ownership associated with future roundwood removals; and changes in the mean age of clearfelling and volume removed per hectare. Forest attrition effects are briefly discussed.
It is concluded that from about 1990 onwards a great upsurge of activity in the forestry sector can be expected which will largely be aimed at export markets.
