“…The ease with which a bole measurement can be made on a standing tree depends upon the select-ed height and whether it is within the crown of the tree. High measurement points may be obscured from view or difficult to locate exactly (Wood and Wiant 1992). Särndal et al (1992) discuss the possibility of cut-off sampling, in which a part of the target population is deliberately excluded from the sampling frame.…”

Cutoff importance sampling (CIS) is introduced as a means of sampling individual trees for the purpose of estimating bole volume. The novel feature of this variant of importance sampling is the establishment on the bole of a cutoff height, He, above which sampling is precluded. An estimator of bole volume between predetermined heights Hi and Hu > H c is proposed, and its design-based bias and mean square error are derived. In an application of CIS as the second stage of a two-stage sample to estimate aggregate bole volume, the gain in precision realized from CIS more than offset its bias when compared to the precision of importance sampling when He = HJJ.
