“…The role of soil seed bank to vegetation development following disturbance has been reported by numerous authors (Yamada et al 2007;Keddy et al 1989;Looney and Gibson 1995;Falińska 1999;Chambers 2000;Zabinski et al 2000;Bossuyt and Hermy 2001;Harwell and Havens 2003;Richter and Stromberg 2005;Lang and Halpern 2007;Lee et al 2008;Li et al 2008;Ma et al 2011Ma et al , 2013Savadogo et al 2017) because it often leads the initial vegetation trajectory and species composition in the course of secondary succession after disturbance. Richness and density of soil seed banks often decrease as vegetation passes through the stages of succession (Pickett and McDonnell 1989;Thompson 2000).…”

Background: We sought to understand the relationship between the seed bank and vegetation in abandoned rice paddies in South Korea, in order to guide management of these sites. We investigated the floristic composition and species richness of the soil seed bank and ground vegetation in former paddies along three seral gradients (wet meadow, young forest, and mature forest) in Gwangneung Forest Biosphere Reserve. Results: Seed bank samples contained 59 species, of which the dominant families were Cyperaceae, Gramineae, and Polygonaceae. Species richness and seedling density (59 taxa and 19,121 germinants from all samples) were high. Carex spp. (11, 921 germinants) were the dominant taxa. The species composition in the seed bank changed gradually as the land transitioned from wet meadow to mature forest. Sørensen's index of similarity between above-and below-ground vegetation was 29.3% for wet meadow, 10.8% for young forest, and 2.1% for mature forest. Germinant density also declined, with 10, 256 germinants for wet meadow, 6445 germinants for young forest, and 2420 germinants for mature forest. Conclusions: Changes in aboveground environment and life history traits such as amphicarpic plants, likely affect the composition of soil seed bank species. Abandoned paddy fields may be good sites for restoration of wetland forest and conservation of wetland habitat. Some intervention may be required to promote the recovery of a natural species assemblage.

“…This pattern is consistent with previous studies (Savadogo et al, 2016;Tessema et al, 2012). More herbaceous species in soil seed banks may be due to the ability of herbaceous seeds dispersed by wind and water to move further from the dispersal point (Savadogo et al, 2016).…”

“…Seeds in the upper layer are more likely to have their dormancy broken by fire or water than seeds in the deeper layer (Williams et al, 2005). Such effect of vertical distribution on species richness is consistent with Savadogo et al (2016) in Burkina Faso and with Tessema et al (2012) in Ethiopia.…”

“…After seed production, seeds first arrive at soil surface where they are captured before entering the deeper soil layer (Thompson and Grime, 1979) and where their dormancy is likely broken by fire or water (Williams et al, 2005). Such effects of vertical distribution on plant abundance in the soil seed banks is consistent with Tessema et al (2012) in Ethiopia, and Savadogo et al (2016) in Burkina Faso.…”

Seed rain and the soil seed bank represent the dispersal of seeds in space and time, respectively, and can be important sources of recruitment of new individuals during plant community regeneration. However, the temporal dynamics of seed rain and the mechanisms by which the seed rain and soil seed bank may play a role in plant community regeneration with increased grazing disturbance remain unclear. Seed rain, soil seed bank, aboveground vegetation, and rodent density were sampled along a grazing gradient in an alpine marsh on the eastern Tibetan Plateau. We described the temporal dynamics of seed dispersal using Bayesian generalized mixed models, and nonmetric multidimensional scaling and the structural equation model were used to examine the effects of grazing disturbance on the relative role of seed rain and soil seed bank on aboveground plant community regeneration. The temporal dynamics of seed rain changed from a unimodal to a bimodal pattern with increased grazing disturbance. Both species diversity and seed density of the seed rain and seed bank increased significantly with increased grazing disturbance. Increased grazing disturbance indirectly increased the similarity of composition between seed rain, seed bank, and aboveground plant community by directly increasing species diversity and abundance of aboveground plant community. However, increased grazing disturbance also indirectly decreased the similarity of seed rain, soil seed bank, and aboveground plant community by directly increasing rodent density. The similarity between seed rain and aboveground plant community was greater than that of the soil seed bank and aboveground plant community with increased grazing disturbance. Grazing disturbance spreads the risk of seed germination and seedling establishment by changing the temporal dynamics of seed dispersal. Plants (positive) and rodents (negative) mediated the role of seed rain and soil seed bank in plant community regeneration. The role of seed rain in plant community regeneration is higher than the seed bank in disturbed alpine marshes. Our findings increase our understanding of the regeneration process of the plant community, and they provide valuable information for the conservation and restoration of alpine marsh ecosystems.
