The evolution of growth and yield models for south Australian radiata pine plantations.

摘要

The evolution of growth and yield models for South Australian radiata pine (Pinus radiata) plantations is traced from the first yield table developed by H.R. Gray in 1931 to the most recently developed growth functions. The adoption of new technologies is discussed both in terms of the techniques available for developing growth and yield predictors and the implementation of them in computerized systems. Growth and yield models in South Australia were initially developed to meet the marketing needs of a plantation resource reaching critical mass. The continuing improvement of the models remains a market driven process due to the increasing intensity with which the forests are being managed to meet the demands for a wide range of log products. Intensive silviculture coupled with genetic improvement of the planting stock requires continuing improvement to growth and yield models.
