The effect of ungulate grazing on various woodland ecosystems was studied in oak-hornbeam forest, subxerothermic oak forest, and herb-rich beech forest of the Křivoklátsko Biosphere Reserve. Samples of soil nematodes were taken in May 2006 from plots within enclosures established in 1993 and from plots outside the enclosures. The total abundance of nematodes varied from 248.7 to 790.0 x 10⁴ ind.m^-2 and was always greater outside the enclosures. In two cases out of four the difference was statistically significant. Bacterivores were the most numerous nematodes. Their abundance was greater only in one plot outside the enclosure in the oak-hornbeam forest and about one half of the bacterivores were short-living Rhabditis. The abundance of root-fungal feeders (mainly Filenchus) was always greater outside the enclosures than within enclosures.
