Valentine, H.T. 1997. Cut-off importance sampling of bole volume. Silva Fennica 31(2): 153-160. Cut-off 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 cut-off height, He, above which sampling is precluded.
