Megjegyzések:	Soil seed banks play a major role in the post-fire regeneration of semi-arid mountain grasslands. Plant species present before fire can determine the soil seed bank (SSB) characteristics in fire-prone ecosystems. However, it remains unclear how the density and species composition of the SSB under the canopy cover of specific shrub species may be affected by fire. Therefore, we designed a study to test the effects of prescribed burning on the viable SSBs under the canopies of two shrub species: Berberis integerrima (with open canopies) and Onobrychis cornuta (with dense canopies). We selected 20 study sites that included separate patches of the two shrub species and nearby herbaceous patches as control. Soil sampling was carried out pre- and post-burning of shrub canopies and the control patch. Soil samples were collected at two depths: 0-5 cm and 5-10 cm, and transported to the greenhouse for germination experiments. The results showed that canopy fire of shrubs decreased SSB density and species richness. However, the effects of shrub burning on SSB were species-specific and these reductions were more pronounced for canopy burning of O. cornuta than for B. integerrima. Total SSB densities decreased by 61% for B. integerrima and 71% for O. cornuta after canopy fire at soil depth of 0-5 cm. At soil depth of 5-10 cm, total SSB density decreased by 45% under O. cornuta after canopy fire, while canopy fire of B. integerrima did not affect SSB density. Herbaceous patch burning had no statistically significant effects on SSB density at soil depths of 0-5 cm and 5-10 cm. The comparison of quantitative and qualitative similarity indices between pre- and postfire species composition of shrub canopy showed that the statistically significant effect of B. integerrima burning on SSB composition was less pronounced compared with O. cornuta. This study indicated that seeds stored within the soil under certain shrub species are at a high risk of mortality during fire. Thus, successful post-fire recovery does not rely on the seed bank reservoir under these shrubs.

Cím:	Filling up the gaps : passive restoration does work on linear landscape elements / Orsolya Valkó, Balázs Deák, Péter Török, András Kelemen, Tamás Miglécz, Béla Tóthmérész

Megjegyzések:	Open landscapes in many parts of Europe have been negatively affected by large-scale drainage and amelioration to support agricultural production. In continental alkali grasslands, amelioration and establishment of drainage ditch systems were typical in the 1950s and 60s. Drainage ditches caused a considerable fragmentation and degradation of natural grasslands; thus several projects aimed at eliminating these linear landscape elements. In a multi-site study, we explored the drivers of grassland recovery after soil-filling of drainage ditches in landscape-scale restoration projects in Hortobágy National Park, East-Hungary. Ditch embankments, formerly built from the excavated soil, were used to fill the 8-m wide ditches and grazing was applied to facilitate the recovery of grasslands similar to the surrounding matrix. Three age classes were selected for the study: 1-, 6- and 8-year-old filled ditches; with nine sites per age group, surrounded by three grassland types (27 ditches in total). We recorded the percentage cover of vascular plant species in 18 plots per ditch, 486 plots in total. We found that the species pool of the filled ditches became more similar to the reference grasslands with increasing successional age and increasing distance to the central zone of the ditches regardless of grassland type. Species richness of the filled ditches became more similar to that of the reference grasslands with increasing successional age. However, we found that several target species, especially salt-tolerant pioneers, could establish even in the first year. Grassland recovery was most successful in sites adjacent to dry grasslands characterised by soils with high salt content, which favoured specialist species and suppressed non-target species. Cover of non-target species was higher in wet meadows with moist, nutrient-rich soils which favoured generalists and non-target species. Our study revealed that passive restoration after soil filling of disused drainage ditches can effectively support grassland recovery even within less than ten years, when restoration sites are surrounded by natural grasslands.
