Abstract:

The two models for estimating the top height of lodgepole pine (Pinus contorta var. latifolia Dougl.) are designed to function over different age ranges: a juvenile height model for total ages below 15 and a height-age model above breast height age 1/2. Four options are available to splice these models together to give a smooth height trajectory near the splice point. The option resulting in the smoothest trajectory uses the juvenile height model below breast height age 0 and the height-age model above breast height age 2, and linearly interpolates heights between breast height age 0 and 2.
