Forecaster Calculator
The Forecaster Calculator is a simple forest simulation tool for radiata pine in New Zealand. For Douglas-fir there is no productivity surface and you will need a specific measurement event to calibrate the model. It simulates the tree growth and the log products produced at a single clearfell age on a per hectare basis.
Its target audience is primarily the small woodlot owner wishing to calculate a rough estimate of the volume and log product mix on a particular site at a particular age. Note that more accurate estimates of volume and log product mix will be produced by taking detailed plot based stem measurements pre-harvest, and inputting these measurements into a pre-harvest forest inventory tool (e.g. Cruiser or YTGen).
