“…These findings indicate that MO helped maintain plant diversity in the lowland meadow. These results were obtained because mowing has relatively homogeneous effects on grasslands, prevents competing dominant species from eliminating competing vulnerable species, improves canopy radiation, ensures the growth of various plant species and thus maintains species diversity (Yang et al, 2012;Kose et al, 2019). Our results are also consistent with the research results of many studies (Verrier and Kirkpatrick, 2005;Socher et al, 2013;Smith et al, 2018).…”

“…These differences among experimental results indicate that the effects of grazing on grassland communities are complex and result from the combined actions of multiple factors; a change in any one factor, such as livestock species, grass type, a climatic conditions or a soil physicochemical property, can greatly affect the experimental results (Liu et al, 2015;Chu et al, 2019;Ji et al, 2020). Compared with the effect of grazing, the effect of mowing on grassland is more spatially homogeneous and can directly lead to significant reductions in the height and cover of grassland plant communities as well as a reduction in the accumulation of grassland litter (Kose et al, 2019). Current opinions on the impact of mowing on grassland plant diversity are more consistent and include the view that moderate mowing cannot only help stabilize grassland plant communities but also promote grassland plant compensatory growth (Yang et al, 2012).…”

Carex meyeriana lowland meadow is an important component of natural grasslands in Hulun Buir. However, in Hulun Buir, fewer studies have been conducted on C. meyeriana lowland meadows than on other grassland types. To determine the most appropriate utilization mode for C. meyeriana lowland meadows, an experiment was conducted in Zhalantun city, Hulun Buir. Unused, moderately grazed, heavily grazed and mowed meadow sites were selected as the research objects. The analysis of experimental data from 4 consecutive years showed that relative to the other utilization modes, mowing and moderate grazing significantly increased C. meyeriana biomass. Compared with non-utilization, the other three utilization modes resulted in a higher plant diversity, and the moderately grazed meadow had the highest plant community stability. Moreover, principal component analysis (PCA) showed that among the meadow sites, the mowed meadow had the most stable plant community and soil physicochemical properties. Structural equation modeling (SEM) showed that grazing pressure was less than 0.25 hm2/sheep unit and that plant biomass in C. meyeriana lowland meadow increases with increasing grazing intensity, temperature and precipitation.

“…Some positive impacts on species diversity in grasslands were reported after 5-10 years of management. For example, positive impacts were reported by Bakker et al (2003) for natural and artificial salt marshes in the Wadden Sea area, Lindborg and Eriksson (2004) for Swedish seminatural grasslands, Kose et al (2019) for Estonian coastal meadows, and Lundberg et al (2017) for coastal dune meadows in Norway. These results suggest that trends in diversity can be detected after a longer restoration period.…”

“…The coastal meadow in favorable conservation status has no trees and shrubs; it has low vegetation, created by grazing or mowing. Some management patterns with different animals and mowing strategies are described by Kose et al (2019). A common restoration practice is to actively destroy reed and clean the meadows from shrubs by mowing or mulching to enable the reintroduction of grazing as soon as possible and improve light conditions for coastal grassland‐specific plant species to encourage their establishment and spreading.…”

The restoration of a threatened type of seminatural grassland-the Baltic Boreal coastal meadows-began in Estonia in 1997. The main causes of degradation of these communities were land abandonment and overgrowth by reed. In 2015, we resurveyed 14 sites and classified as (1) permanently managed or (2) restored before 2005, or (3) after 2005. In 2015, all sites were managed under the EU agri-environmental scheme and classified as permanently managed or restored before or after 2005. The resurvey focused on assessment of the long-term success of restoration, comparing the vegetation parameters of restored meadows with permanently managed meadows (which were considered as reference). Our study revealed that historical management patterns have an impact on the species richness of these habitats, as more species were found in historically mown meadows, even if the sites were restored by grazing. However, species richness was not an important indicator of coastal meadow recovery. The best indicators of restoration success are evenness and coverage of low-lying, light-demanding, salt-tolerant, wintergreen, cryptophyte, and hemicryptophyte plant species. Phragmites australis is a good indicator species for the habitat, as its abundance indicates poor habitat quality. The study indicated that the recovery of coastal meadow habitat from abandonment requires more than 15 years of restoration activities, and suggested the 3-year restoration period covered by conservation measures and funds is not enough. Therefore, we recommend that agri-environmental schemes should support additional restoration activities for recently restored meadows which are entering the management scheme.

“…Sheep husbandry can sustain rural livelihoods but can also damage the environment and therefore poses significant challenges to policy makers (see, e.g., Bunce et al, 2018aBunce et al, , 2018b. While sheep grazing can promote floristic diversity (Metera et al, 2010), it can also damage sensitive species (Kose et al, 2019). A better understanding of the comparative importance of animal and of vegetation factors in modulating grazing behavior could contribute to resolving such conflicts.…”
