Forest Service Felling Decision Tool

If your species is not present use the nearest equivalent e.g. Japanese larch for Hybrid larch.

Estimate yield class

If the plantation has higher volume production than yield model estimates,
use the next highest yield class, if lower then use the next lowest yield class.

Yield class estimator:

Top Height is the average height in metres of the 100 largest diameter trees per hectare.
Valid entries are from 4 metres up to 25 metres

Age is current year minus the planting year. For crops planted in the autumn
subtract one year from the calculated age.


Be aware that not all rotations types are possible on every site due to stability and technical constraints.

If your management prescription is not present, use the nearest equivalent e.g. 3 Thin for a two thin prescription.

The older the plantation, the shorter the timber price series you should use.

Generally most analysts use 5% but if the plantation is middle-aged or approaching clearfell, then 4% may be more appropriate.
