Picea abies plantation in Mt. Eifel, Germany was studied phytosociologically, with special reference to species composition, structure, ecology and dormancy form, comparing to those of Fagus sylvastica population that once dominated the P. abies plantation. Thirteen plant species appeared on average. According to their ecological distribution, they were classified into three groups, F sylvastica forests, natural coniferous forests and bare-land after clear-cutting. In Luzulo-Fagetum population, Luzula luzuloides was the dominated species while in P. abies plantation was dominated by Avenella flesuosa. In assessment of herbaceous plants by indicator species of Ellenberg, increasing number of shade-intolerant species and acid-tolerant species occurred. In analysis of plant dormancy form, species of Chamaephytes, Phanerophytes and Hemikryptophytes increased, while that of Geophytes decreased. As a result, we found P. abies plantation unstable in ecological aspects.
