Abstract: Research report on the reliability of results of Lithuanian forest inventories is given in the thesis. Aim of research – to estimate the reliability of the results of National forest inventory, Stand-wise forest inventory and forest inventory before cutting. Object of research – spruce and birch stands of Lithuanian forests. Methods of research – sampling, verification of statistical hypotheses and comparison of averages. Results of research – the reliability analysis of the results of National forest inventory shows, that calculated differences are statistically inconsequential. The reliability analysis of the results of Stand-wise forest inventory shows, that Stand-wise forest inventory results has allowed errors, except the height. The estimation of the reliability of results of forest inventory before cutting demonstrates that the errors are too high and the inequality of total volume of stands is -11,1 %.
