“…Many studies have shown that plant species richness and the number of target species are higher on plots that have received fresh hay compared to control plots, where sowing of grass species or no seed was applied [32][33][34]. Moreover, mulching is an effective method to reduce growth and development of Solidago seedlings [16,27], and hay can serve a similar purpose.Many studies have investigated eliminating Solidago spp. and restoring grasslands, but few studies have been devoted directly to restoring meadows invaded by alien Solidago spp.…”

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...

“…Stengelfragmenten bezitten geen reservestoffen die toelaten lange ongunstige perioden te overleven. Tijdens een droge periode zullen ze al snel afsterven en onschadelijk worden (Monty et al, 2014). De rizomen zijn hard en taai en kunnen een lange ongunstige periode overleven om bij goede omstandigheden terug uit te schieten.…”

“…It has also been documented in ruderal habitats, where short-lived species survive severe disturbance and some new individuals establish from root fragments (Klimešová et al, 2008 ; Martínková et al, 2016 ). Enforced clonality, however, has importance in other contexts as well, including habitats with natural soil disturbances such as landslides, scree, and water erosion (Hess, 1909 ), colonization of new areas, spread of invasive plants (Bailey et al, 2009 ; Lin et al, 2012 ; Monty et al, 2015 ), and vegetatively propagated crops and ornamentals (Shepherd et al, 2013 ; de Souza et al, 2014 ; Birlanga et al, 2015 ).…”

In largely clonal plants, splitting of a maternal plant into potentially independent plants (ramets) is usually spontaneous; however, such fragmentation also occurs in otherwise non-clonal species due to application of external force. This process might play an important yet largely overlooked role for otherwise non-clonal plants by providing a mechanism to regenerate after disturbance. Here, in a 5-year garden experiment on two short-lived, otherwise non-clonal species, Barbarea vulgaris and Barbarea stricta, we compared the fitness of plants fragmented by simulated disturbance (“enforced ramets”) both with plants that contemporaneously originate in seed and with individuals unscathed by the disturbance event. Because the ability to regrow from fragments is related to plant age and stored reserves, we compared the effects of disturbance applied during three different ontogenetic stages of the plants. In B. vulgaris, enforced ramet fitness was higher than the measured fitness values of both uninjured plants and plants established from seed after the disturbance. This advantage decreased with increasing plant age at the time of fragmentation. In B. stricta, enforced ramet fitness was lower than or similar to fitness of uninjured plants and plants grown from seed. Our results likely reflect the habitat preferences of the study species, as B. vulgaris occurs in anthropogenic, disturbed habitats where body fragmentation is more probable and enforced clonality thus more advantageous than in the more natural habitats preferred by B. stricta. Generalizing from our results, we see that increased fitness yielded by enforced clonality would confer an evolutionary advantage in the face of disturbance, especially in habitats where a seed bank has not been formed, e.g., during invasion or colonization. Our results thus imply that enforced clonality should be taken into account when studying population dynamics and life strategies of otherwise non-clonal species in disturbed habitats.
