The methodology of a topological mapping procedure for estimating the total number of insects inhabiting a tree trunk is presented. Data necessary for using the procedure are insect densities at measured intervals on the bole. The procedure minimizes errors resulting from smoothing, regression or extrapolation and provides estimates suitable for evaluating bias and variability of other sampling plans.
