The iterative techniques that are currently used to obtain years to breast height and green-up ages (3 m green-up height) from the juvenile height model for lodgepole pine (Pinus contorta var. latifolia Dougl.) are cumbersome. Years to breast height and green-up age models were developed by generating age data from the juvenile height model and fitting a model to the data. These models result in years to breast height and green-up age estimates that are consistent with the juvenile height model.
