This booklet, with its associated yield models and curves, replaces Forestry Commission Booklet Number 34 Forest Management Tables (Metric) by G. J. Hamilton and J. M. Christie, which was published by HMSO in 1971. Yield models can be constructed to simulate the effects of any silvicultural treatment, and the ‘normal yield tables’ included in the earlier publication were models of a specified ‘normal’ treatment. A much wider range of yield models is now available. The format of the yield models is very similar to that of the Normal Yield Tables published previously, except that the current annual increments and the assortment forecasts have been omitted. The models have again been produced directly from computer output.

A new version of this Booklet was produced in 2016 – Forest Yield: A handbook on forest growth and yield tables for British forestry.
