“…This phenomenon may be due to the vicinity of other plant communities such as calcareous grasslands, woodlots, and old fields. The obtained results, documenting that seedlings of Filipendula ulmaria, Geum rivale, Solidago canadensis and Iris sibirica appear mainly in round openings, are consistent with other studies [51][52][53][54][55][56] documenting that the absence of plants in the near vicinity and little competitive pressure from established vegetation may accelerate the recruitment process of these species. The observed greater recruitment of seedlings of Galinsoga sp.…”

Cessation of the management of semi-natural habitats such as grasslands and meadows contributes to secondary succession and encroachment of native and alien tall-growing perennials, large tussock grasses, shrubs, and trees. Thus, the formation of gaps in the plant canopy and litter, enabling seedling recruitment, appears to be a very effective method for the restoration of several plant communities. The main objective of the research was to assess the effect of the shape of openings on microenvironmental conditions and seedling recruitment in Molinietum caeruleae patches in various habitat conditions. In all study patches, circular and linear openings, comparable in area, were randomly created through the removal of plant canopy and litter layer. The circular gaps presented greater light availability and lower soil humidity than linear openings, while soil temperature within differently shaped openings was similar. Regardless of differences in microenvironmental conditions, the total number of seedlings in differently shaped gaps did not vary considerably. Three plant categories were found: (i) those recruited mostly in circular openings, (ii) those recruited mostly in linear gaps, (iii) those colonizing circular and linear gaps similarly. The colonizers of circular gaps represented various synecological groups (ruderal, grasslands and meadows, young tree communities) and diverse life forms (therophytes, hemicryptophytes, chamaephytes, phanerophytes), while the colonizers of linear gaps were meadow and grassland hemicryptophytes. The formation of linear openings contributes to increases in the abundance of meadow taxa, while the creation of circular openings may have a negative effect, contributing to the promotion of the secondary succession process.

“…Similar phenomenon were also noted in populations of Ranunculus repens (van Kleunen et al 2001), Hieracium pilosella L (Winkler & Stöcklin 2002), Scirpus olneyi A. Gray (Ikegami et al 2004) and Iris sibirica L. (Kostrakiewicz 2007). Furthermore, presented findings stay in accordance with predictive models Newell and Tramer (1978), as well as Takada and Nakajima (1996).…”

Abstract. The effectiveness of asexual and sexual reproduction of rare, clonal species Dianthus superbus L. were conducted in the years 2008-2010 in Kostrze (Southern Kraków). The observations were carried out in Molinietum caeruleae patches dominated by small species creating delicate, erect or procumbent stems (MC), prevailed by tall grasses (GR), and overgrown by willows (SA). The number of above-ground units per ramet cluster were much greater in MC patch, than in sites GR and SA. Controversially, the number of fruit per generative shoot and seed production were greater in GR and SA patches, than in MC patch. The highest seedling recruitment, occurring only in artificially created gaps in plant canopy and litter was noted in patch MC, while the decline of genet emergence were found in SA and GR patches. In light of performed studies, it should be concluded, that population established in patch dominated by small meadow species has the greatest chance for survival, whereas populations inhabiting sites prevailed by tall grasses or overgrown by willows have much lower possibilities of persistence in occupied places.

“…This dense grass matrix might have inhibited the establishment of target species (Donath et al 2007), such as that of Iris sibirica. It is known that recruitment of this species strongly depends on gaps as safe sites for germination and seedling development (Kostrakiewicz 2007). Other factors that could have affected the successful establishment of target species might have been differences in abiotic conditions, the applied measures or species-specific demands.…”

1. Species-rich grasslands are highly endangered habitats in Central Europe. To halt their ongoing loss, many sites have become subjects of restoration efforts. Traditionally, restoration success is measured using target species or by comparing similarity in species composition. Here, we suggest to additionally use functional community composition to assess restoration success as functional traits might offer mechanistic insights into restoration processes. 2. In a 5-year restoration experiment, we annually evaluated the responses of (i) floristic composition and species diversity, (ii) number and cover of target species, (iii) functional identity and (iv) functional diversity to four different methods of assisted recolonization through species introduction: hay transfer and application of threshing material from a local provenance, combined with and without addition of regional seed mixtures of target species, as well as to a control treatment. 3. Across all treatments, floristic composition, species diversity, and number and cover of target species approached the values of reference sites. In the last observation year, Shannon diversity was still lower in all treatment plots than in the reference plots, while the number of target forb species had reached or exceeded the reference levels. We demonstrated that the community was also restored functionally in many aspects, but not in all studied traits. Calculated community-weighted means (CWMs), specific leaf area (SLA) and leaf dry matter content (LDMC) in experimental plots did not differ significantly from the reference plots, thereby indicating that productivity of restored sites had reached target values. In contrast, CWMs of strategy types and pollination modes revealed significant differences, showing that biotic interactions among plant species and with other trophic levels have not yet been fully restored. However, almost all CWMs showed a trajectory towards the reference, thus giving a positive prospect for the future development. With respect to functional diversity (FD), we found steadily increasing FD values for almost all traits analysed. 4. Synthesis and applications. We demonstrated that all applied restoration measures were appropriate to achieve the restoration aim in terms of species composition of a given community and the establishment of target species. With respect to many functional traits, the restored meadows were already as functional as communities from the reference sites. Hence, including functional criteria did not only corroborate traditional criteria of restoration success but also allowed identifying those floodplain meadow's functions that can be quickly and less quickly restored.
