Species from genus Solidago are exceptionally successful worldwide invaders from North America [1]. Among about 120 Solidago species three are invaders, which so far have conquered Europe, large parts of Asia, Australia and New Zealand [2].In central Europe five representatives of the Solidago genus are found. Only one species (S. virgaurea L.) is native, while the other four are of American origin, namely: S. gigantea Aiton, S. canadensis L., S. altissima L. [S. canadensis var. scabra (Muhl.) Torr. and Gray] and S. graminifolia (L.) Elliot [3]. Three of the introduced taxa (S. gigantea, S. canadensis and S. altissima) are invasive and morphologically similar to each other. Their taxonomic status in Europe has been discussed [3][4][5][6][7][8]. The range of the fourth alien species, S. graminifolia, is small and limited to few locations in Europe [9,10].The basic chromosome number in Solidago species is x = 9. S. virgaurea and S. graminifolia are diploids (2n = 18). S. canadensis consists of diploid (2n = 18) and tetraploid plants (2n = 36), and S. altissima hexaploid (2n = 54), triploid (2n = 27) and tetraploid (2n = 36) plants of native origin [11,12]. While in Europe only diploid plants of these species are noted [7,13], in case of Solidago altissima the occurrence of additional Bchromosomes was observed [14,15]. Solidago gigantea occurs in three different cytotypes: diploid (2n = 18), tetraploid (2n = 36) and hexaploid (2n = 54), which represent the whole S. gigantea complex in native range and has also been found in Europe [16]. However, according to current data [17][18][19] in Europe only tetraploid populations of S. gigantea are known. Therefore, based on this variety in chromosome number, considerable morphological variety in these taxa could be expected [20]. It could also include differentiation in traits related to invasiveness as, e.g. stem height or inflorescence size [21].Several hypotheses focus on the reasons why alien invasive plants are more successful than other plants in occupying new areas [22][23][24][25]. There are numerous confirmations, that plants in the new range could differ from their ancestors, including AbstractInvasive plants in their new range can differ from their ancestors, including traits ultimately influencing habitat preferences, competitiveness and dispersal ability. In Europe Solidago species are considered as one of the worst invaders of American origin. In this study the frequency of occurrence of Solidago species, their soil preferences and morphological diversity, in Silesia (southwestern Poland, Central Europe) were surveyed. On the basis of phytosociological relevés, made using the Braun-Blanquet method, in 75 plots, we determined the composition of species co-occurring with particular Solidago species. The height of ramets, as well as length and width of inflorescences of Solidago species were measured. We also determined the basic soil properties and noted the presence of trees overshading the ground vegetation. The compositional variation of vegetation and its r...

Exotic plant species that spread into natural and seminatural plant communities are a serious threat to native species and affect the structure and dynamics of the vegetation [1]. The majority of invasive plant species are strong competitors that displace native species, decrease biodiversity, and alter ecosystem services [2][3].Traditional grasslands in Europe include some of the most species-rich habitats and richest soil biodiversity. A grassland provides a range of ecosystem services, from meat and dairy products to recreational and tourism opportunities, and also creates a considerable carbon sink. More than 80% of semi-natural grasslands have been Pol. J. Environ. Stud.

The majority of these communities are protected by the European Natura 2000 system. However, grasslands are threatened by invasions by alien species, particularly Solidago spp. The invaders should be eradicated because of their negative impact on biodiversity, the environment, and the economy. A field experiment was conducted to compare the effect of different treatments (scalping, rototilling, and use of herbicide) on restoration of a meadow seriously invaded by Solidago spp. Fresh hay was transferred to the experimental plots to provide target meadow species seeds. Significant differences in species composition and coverage were detected between the herbicide-treated and plots that received other treatments and between the use of a rototiller and the control. Applying the herbicide glyphosate quickly reduced the cover of Solidago spp. (0.5±0.4%) and increased target species cover (84.8±13.6%). The Solidago spp. cover rates were 79.5±17.1% and 65±31.4% when scalping and rototilling were used, respectively, whereas the target species cover rates were 25.8±16% and 30±15.8%, respectively. The sward that grew after applying glyphosate had the highest forage value and resistance to cutting. These results show that short-term eradication of invasive Solidago spp. and restoration of a meadow are possible using glyphosate. However, use of a herbicide may have a negative impact on the environment and native species.Keywords: invasive species, semi-natural meadows, species composition, hay transfer, restoration 1252 Świerszcz S., et al. lost in the last 100 years due to intensified production or abandonment. A large number of grassland species have declined or become extinct [4][5][6][7]. Therefore, many semi-natural grasslands in the pan-European Nature 2000 network are protected, as specified in Annex I of the Habitat Directive. Despite this protection, the effects of abandoning agriculture remain visible in Central and Eastern Europe. It is an effect of the collapse of the socialist regime in the early...

“…The authors argued that this may increase the ability of S. gigantea to compete against established species in dense stands or nutrient-poor sites. Meyer et al (2005) tested the evolution of increased competitive ability hypothesis and found that European (introduced) S. gigantea are less resistant to American foliar pathogens and do not perform as well in the presence of insect herbivores as American (native) S. gigantea. Weber (2001) found evidence that strongly suggested that the spread of S. gigantea has not reached its limits and that its range expansion will continue.…”

Abstract. The world's biodiversity and ecosystems are threatened by the invasion of alien plant species. They have been found to impact the structure in function of ecosystems in temperate, tropical and subtropical areas (Holm et al., 1977;Pysek, 1997;Byers et al., 2002;Ehrenfeld, 2003). We reviewed studies to summarize the impact of four plant species invasions on European ecosystems: Solidago gigantea, Prunus serotina, Heracleum mantegazzianum and Fallopia japonica, because they are amongst a number of invasive species which have spread over the last centuries, and are still increasing their range in Europe. They cause negative impacts on both native biodiversity and ecosystem functioning (including productivity, nutrient cycling and soil organic matter dynamics).
