Gresham House target highly commercial plantations, generally with an average yield class of 16 and above. A yield prediction model uses the quantitative relationships between measured growth variables to predict yields of forest types, and is a tool that helps to schedule and regulate harvests at sustainable levels. Other species listed in Appendix 1 of the user manual, for which models have not been developed, are mapped to these more ‘commercial’ species on the basis of growth and silvicultural characteristics. Because of the requirements of the models and limitations of the planning data, the main variable driving the yield models was age.

Gresham House target highly commercial plantations, generally with an average yield class of 16 and above. A yield prediction model uses the quantitative relationships between measured growth variables to predict yields of forest types, and is a tool that helps to schedule and regulate harvests at sustainable levels. Other species listed in Appendix 1 of the user manual, for which models have not been developed, are mapped to these more ‘commercial’ species on the basis of growth and silvicultural characteristics. Because of the requirements of the models and limitations of the planning data, the main variable driving the yield models was age.
