Megjegyzések:Grassland restoration is gaining momentum worldwide to tackle the loss of biodiversity and associated ecosystem services. Restoration methods and their effects on ecological community reassembly have been extensively studied across various grassland types, while the importance of post-restoration management has so far received less attention. Grassland management is an important surrogate for natural disturbances, with which most ancient grasslands have coevolved. Thus, without the reintroduction of management-related disturbance, restoration targets are unlikely to be achieved in restored grasslands. In this study, we aimed to explore how 20 yr of management by mowing once a year or light cattle grazing affects restoration success in Palearctic meadow-steppe grasslands restored by either sowing native grasses (sown sites), applying Medicago sativa as a nurse plant (Medicago sites), or allowing spontaneous succession (spontaneous sites). We found that, following mowing, sown sites maintained long-lasting establishment limitation, while Medicago sites experienced a delay in succession. These limitations resulted in low total and target species richness, low functional redundancy, and distinct species and functional composition compared to reference data from ancient grasslands. Spontaneous sites that were mowed reached a more advanced successional stage, although they did not reach reference levels regarding most vegetation descriptors. Sown and Medicago sites that were grazed had higher total and target species richness than those that were mowed, and showed restoration success similar to that of spontaneous sites, on which grazing had only moderate further positive effects. Grazed sites, irrespective of the restoration method, were uniformly species rich, functionally diverse, and functionally redundant, and thus became important biodiverse habitats with considerable resilience. We conclude that an optimally chosen post-restoration management may have an impact on long-term community reassembly comparable to the choice of restoration method. Restoration planners may, therefore, need to put more emphasis on future management than on the initial restoration method. However, our findings also imply that if local constraints, such as potentially high invasive propagule pressure, necessitate the application of restoration methods that could also hinder the establishment of target species, the long-term recovery of the grassland can still be ensured by wisely chosen post-restoration management.

Cím:Recovery of species richness lags behind functional recovery in restored grasslands / Csaba Tölgyesi, Péter Török, Róbert Kun, András István Csathó, Zoltán Bátori, László Erdős, Csaba Vadász

Megjegyzések:Restoration of grasslands on abandoned croplands is a major opportunity for land development in degraded landscapes. In this study, we compared the success of three restoration measures, spontaneous recovery, perennial-crop-mediated restoration, and sowing native grasses, by using a unique combination of species-based and trait-based approaches. We sampled 373 4-m(2) plots in nearly 1,000 ha of 20-year-old-restored grasslands and 72 4-m(2) plots in three neighbouring ancient grasslands. Species richness and target species cover were higher in spontaneously recovered sites than in other restored sites, but reference sites had higher scores than all restored sites. Spontaneous sites had higher functional diversity than the other restored sites. Spontaneous and reference sites showed little difference in their functional diversity and in the community-weighted means of relevant traits. Our findings indicate that the establishment limitation effect of the initial application of perennial crops or sowing competitive grasses can last for decades, hindering the recolonization of target species and the recovery of functional diversity; thus, they should be applied in landscapes with high cover of natural habitats only when inhibiting undesirable species is of paramount importance. The similar levels of functional niche saturation in spontaneous and reference sites may also indicate a self-developed establishment-limited situation after 20 years of succession. In combination with this, the lagging recovery of species richness entails lower functional redundancy in spontaneous sites. Our results underline the necessity of postrestorative management methods that reduce establishment limitation and contribute to the recolonization and subsequent coexistence of functionally similar species..
