Height-Age Relationships for Regeneration-Size Trees in the Northern Rocky Mountains, USA.

摘要

Regression equations were developed to predict heights of 10 conifer species in regenerating stands in central and northern Idaho, western Montana, and eastern Washington. Most sample trees were natural regeneration that became established after conventional harvest and site preparation methods. Heights are predicted as a function of tree age, residual overstory density, elevation, site preparation, habitat type series, and closest National Forest location. Equations are presented that can be used to predict heights at a given age or to predict the number of years required to reach a specified height.
