In the Lemnitz forest district as well as in other forest districts of the Thuringian and Saxonian Vogtland county, Germany, so-called Green Eyes were installed around 1938. These are small-sized plantations of beech (Fagus sylvatica) within large complexes of conifer stands. In the presented paper, the influence of beech on soil and the growth of beech were investigated in comparison with neighbouring even-aged spruce stands (Picea abies) 60 years after planting. For this purpose, 10 pairs of investigation plots were selected in which soil profiles were ditched, samples of the humus layer and the mineral soil were taken, and root density and the diversity of Lumbricidae were investigated. Further, the growth of the stands was recorded.
