Forecasting Tree Growth and Yield and Financial Returns of Key Agroforestry Species across Southern Australia

The main objectives of the project are:

1. To improve the reliability of forecasting tree growth and yield of key agroforestry species on cleared agricultural land across southern Australia, by developing height, stand basal area and volume predictions according to grouped site productivity classes
2. Use these predictions (plus spacing) to create models of tree growth for future inclusion into financial models
3. To improve landholders knowledge of relative economic returns and benefits of different agroforestry regimes
   This report illustrates the application of the chosen growth models and reports on the methodology for assigning log diameter functions or diameter distributions.

Forecasting Growth of Key Agroforestry Species in South-Eastern Australia

The main objectives of the project are:

1. To improve the reliability of forecasting tree growth and yield of key agroforestry species on cleared agricultural land across southern Australia, by developing height, stand basal area and volume predictions according to grouped site productivity classes
2. Use these predictions (plus spacing) to create models of tree growth for future inclusion into financial models
3. To improve landholders knowledge of relative economic returns and benefits of different agroforestry regimes
   This report presents growth data for a number of Eucalyptus species from a range of sites, and models growth using site types based on rainfall and soil classes. The growth functions are suitable for use by extension proiders and farm foresters.
