A sugar maple (Acer saccharum Marsh.) - yellow birch (Betula alleghaniensis Britton) - beech (Fagus grandifolia Ehrh.) stand has been treated in 1963 by two thinning intensities. Yellow birch stems of the sample plots established before cutting have been studied in 1972. The various characteristics determining stem quality were considered in factorial analysis. Branch number did not affect stem quality to any degree; curve and diseases of the stem contributed equally to its qualitative depreciation. Thinning intensity did not substantially affect branch number and curve of the stem. Competition removal in a radius up to 6 m around yellow birch did not cause stem diseases. On the contrary, the growth increase inherent in the thinning has helped wound closure and has checked disease entry.
