| Abstract: | Presents a study of the feasibility of estimating the total stem volume and aboveground biomass from data of only the largest trees in even-aged pure stands. Method of fitting a size-distribution function to data that exclude information of smaller individuals in a stand and compared the predicted stem volume and aboveground biomass with those calculated with data of all living trees in the stand; Paired t test that showed the predicted values of the total stem volume and aboveground biomass were not different (p = 0.05) from those observed even if only the largest 10% of the trees were used for estimation with the ?3/2 power distribution; Results that were similar with the beta-type distribution; Data from at least the largest 30% of the trees in the stand that must be included; Absolute values of the relative error of the predicted total stem volume or aboveground biomass that were generally in the range 10?20%, indicating that the present method is accurate enough to be used for calculation of these variables; Systematic bias in the predictions of the total stem volume and aboveground biomass of a stand that exists; Possible causes of the indicated biases and potential ways for improvement of the predictions that were discussed. |
