ABSTRACT
The article explains the processes involved in accurately measuring radiata pine and forecasting yields as well as future developments in this area. Reliable yield forecasts are based on stand measurements and yield modelling for structural timber and pruned log quality. PF Olsen's Silmetra Plotsafe, YTGen and Atlas Forecaster are tools that can be used for detailed descriptions of sweep, branching, diameter and other stem features. YTGen provides a model to forecast structural log yields using sonic testing, the most reliable method in identifying better and stiffer structural logs. The Pruned Log Index is used to measure potential clearwood recovery, a factor in log quality. Remote sensing and other survey type equipment can help improve future volume forecasts and tree descriptions.

These trials contained 63 unique seedlots with different levels of genetic improvement....
