An Application of Two-Stage Forest Sampling
A method of two-stage forest sampling is presented. The first stage is Bitterlich sampling, and the second stage (subsampling) is by PPS sampling. The method is suitable for use in updating an earlier survey or in returning to the field to obtain intensive measurement for the selected subsample trees after the first-stage sampling has been completed. The necessary equations are given and their use shown by numerical example.
