In order to identify the quality of natural Silver birch stands in Latvia, fifteen sample plots covering all country's regions were established. Stem quality affecting morphological traits - stem straightness, branch angle, branching thickness and branching patterns were measured and assessed to all birches in sample plots. To compare the stand's quality, the integral quality indicator was introduced. According to results obtained in plots, most quality birch stands in Latvia are located in East and North parts of Latvia. The best stands proved to be in Aluksne and Smiltene. Birch stands in West part of Latvia had stems of substantially lower quality. The best quality stand in this region was birch stand located in Tukuma's head forestry.
