Megjegyzések:	The soil seed bank (SSB) and soil microbial communities are among the most crucial drivers of belowground biodiversity in grass-lands. Changes in components of soil biodiversity following protection from grazing were observed in cold, semiarid grasslands. Tostudy these changes, soil samples were taken in an intensively grazed area and in an exclosure established 20 years prior to this study.In particular, changes in biodiversity components such as SSB and microbial activities in two soil depths (0-5 and 5-10 cm) weremeasured. Nonmetric dimensional scaling showed that after grazing removal, the SSB had changed. SSB density, richness, anddiversity were higher in the ungrazed plots. The increase in SSB density and diversity in the exclosure may have been caused bythe absence of direct adverse effects of grazing on the SSB, like trampling and plant consumption, or by reduced indirect effects, suchas seed germination facilitation in canopy gaps created by grazing animals. The effect of grazing removal on basal respiration,substrate-induced respiration, and urease activity was highly signi?cant (p < 0.01) and may be due to an increase in soil moistureafter grazing exclusion. The effect of grazing removal on soil biological parameters was greater in the upper layer than in the deepersoil layer. This study shows that grazing exclusion can be a useful approach in restoring components of soil biodiversity.
