Optimum sampling of sample trees for volume equations
Vanclay, JK 1982, Optimum sampling of sample trees for volume equations, Department of Forestry, Queensland, Brisbane, Qld.
This note deals with the characteristics of a satisfactory predominant height volume equation, and suggests a sampling intensity which should achieve an equation with such characteristics. Sampling should attempt to include at least two trees per 1 cm d.b.h.o.b. x 2 m predominant height cell, in every cell for which sample trees can be found. It is particularly important to sample for extreme values of data.
