Abstract: Theoretical advantages in using angle counting, post-stratification and sampling with partial replacement to improve estimates of mean basal area per unit area are briefly reviewed. Worked examples for Ashley Forest show empirically how to gain these improvements in accuracy and precision through post-stratification and sampling with partial replacement. Use of these sampling techniques would be even more worth while if regional inventories corresponding to regional planning units were to be carried out, rather than inventories in .single forests.
