Description
This unit of competency describes the skills and knowledge required to select and apply a forest growth model to forecast forest growth and yield of a forest stand and to compare forecasts with actual yields.The unit applies to individuals who undertake forester or forestry field officer job roles in the forest industry. All work must be carried out to comply with workplace procedures according to state/territory health and safety regulations, legislation and standards that apply to the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Select method of forecasting forest growth and yield
- 1.1 Classify stand characteristics that most affect forest growth and yield
- 1.2 Research different methods of forecasting forest growth and yield
- 1.3 Determine the key features and data requirements for different forest growth models
- 1.4 Establish criteria for selecting a method of forecasting forest growth and yield
- 1.5 Apply the selection criteria to determine the appropriate method for forecasting forest growth and yield for a stand
2. Apply a forest growth model to forecast forest growth and yield
- 2.1 Explain how growth models are used to compare results of different silvicultural regimes and scheduling pruning and thinning operations to forestry personnel
- 2.2 Determine the data, including site index, species and genotype, age, establishment stocking, current stocking and basal area, required to simulate forest growth and forecast yield using a growth model
- 2.3 Acknowledge the limitations of inventory data and the effects of inaccurate data from pre-harvest inventory on forecasts
- 2.4 Use a simple stand volume formula to derive the total stand volume for a set of forecasts of basal area and mean top height
- 2.5 Derive current annual increment and mean annual increment
- 2.6 Use a stand growth model software package to simulate the growth and yield of a stand from establishment to clear felling
3. Compare forecasts with actual harvest yields
- 3.1 Review forecasted yield data for a forest stand
- 3.2 Collate actual harvest yield data for a forest stand, and compare with forecast yield
- 3.3 Document and account for discrepancies between actual and forecast harvest yield
- 3.4 Report on comparison of forecast and actual harvest yield to appropriate personnel, noting potential implications for silviculture practices and forest growth modelling techniques
