Abstract:

Inconsistencies between breast height age and adjustments for sectioning bias in stem analysis data may cause a bias in height-breast height age prediction systems. A further bias may be introduced when applying the model if the breast height age of the tree is taken to be the ring count at breast height. These biases can be removed by making the model and data compatible with the definition of breast height age.
