The aim of this study was to characterize the coenosis of Lumbricidae in forest stands (Krusne hory Mts., Czech Republic) with soils disturbed by long-term acidification and affected repeatedly by aerial ameliorative liming. Ten species of earthworms were recorded. The earthworms Dendrobaena attemsi, Dendrobaena octaedra and Dendrobaena vejdovskyi which are considered to be acidotolerant showed the highest abundance. They were recorded especially at soil pH 2.8-6.2. Ubiquitous species developed in soils of markedly lower pH, viz. Lumbricus rubellus (2.8-5.6), Aporrectodea caliginosa (3.1-5.5), and Octolasion lacteum (3.2-5.2). Dendrobaena attemsi responded positively to low saturation of the base-exchange complex, low C/N ratio and high content of phosphorus, and negatively to the high level of calcium. D. octaedra responded positively to the high level of calcium and D. vejdovskyi to the high content of potassium.
