Soil micro- and mesofauna was studied in four spruce clearings in the Šumava Mts., covered by vegetation of Junco effusi-Calamagrostietum villosae. The total average abundance of nematodes varied from 1527 to 3864 x 10 3 ind.m-2 in individual localities (mean value 2833 x 10 3 ind.m-2). Root-fungal feeders were the most abundant nematodes mainly represented by Aglenchus agricola (about 50% of all nematodes) and by Filenchus spp. (5%, mostly F. misellus). The second most abundant trophic group were bacterivores (29%,mostly Acrobeloides nanus and Plectus spp.) followed by omnivores (6%, mostly Eudorylaimus spp.). The number of nematode species in individual localities varied from 51 to 57, the number of genera from 29 to 33. Generic heterogeneity of spruce clearing fauna was relatively low (mean H´gen = 1,92), as well as the value of maturity indices (SMI = 2,19, MI = 2,40, PPI = 2,01. (The mean abundance of enchytraeids in the set of localities studied was 55 x 10 3 ind.m-2, of rotifers 134 x 10 3 ind.m-2, of tardigrades 125 x 10 3 ind.m-2, and of copepods 5 x 10 3 ind.m-2.
