Abstract:

This handbook discusses the silviculture survey system used by the B.C. Ministry of Forests to assess stands for free-growing status. The silviculture survey system is reviewed, and the decision curve as a statistical tool to assess risk is explained. Decision curves are used to explore the effects of changes to survey parameters, as determined by a simulation study of homogeneous stem maps.

Projected volumes for homogeneous lodgepole pine stands (based on TASS, a growth and yield model) are also presented and discussed. The simulation study did not investigate the effects of disease, infestation, or brush competition on volume: all trees were assumed to be healthy and unimpeded by vegetation.
