| Abstract: | The accuracy and precision of the topological mapping procedure for estimating within-tree populations of bark beetles was investigated for a variety of different sampling conditions. Simulation techniques were used to define the mean and standard deviation of proportional errors encountered in estimation under different sampling intensities. The number of samples collected at a particular height and the vertical spacing between heights were varied. Information presented should aid in developing sampling plans for studies of bark beetle populations and will permit the reexamination and/or recovery of historical data sets on bark beetle populations. |
