“…The dominant vegetation types in South Korea are secondary and plantation forests. Most low-height vegetation, including grasses and shrubs, in lowlands transitioned to forest vegetation over time (Cho et al 2016); thus, utilization of abandoned agricultural fields as managed and cultivated habitat has been strongly encouraged in Japan and South Korea recently (Kurechi 2007). Our results showed that the floristic composition of soil seed banks in abandoned rice paddies revealed important roles for spontaneous and rapid development of secondary habitats.…”

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.

“…One of the consequences of urbanization is that the development of the city encroaches upon agricultural land. Conversion of agricultural areas from conventional rice paddies and fields to modernized operations using greenhouses was a significant change in Asian countries (Cho 2005b;Li et al 2005;Tan et al 2005). The increase in urbanized area corresponds to regional population growth, which increases the need for industrial and residential areas and roads.…”

“…Careful planning, including diagnostic evaluation of the target area, site preparation through terracing on steep slopes, and selection of a site-specific plant assemblage, was also important (Cho et al 2016). Furthermore, intensive post-planting activities were conducted, including periodical fertilization and weeding in the early years of the restoration project.…”

Ecosystem management in South Korea dramatically changed in the early 1970s, shifting from historical utilization of natural resources to a strong management system that included forest promotion and restoration. The socio-economic and biological context underpinning this effort and the ecological consequences of this new policy have not been studied in South Korea. We analyzed landscape dynamics over a 90-year period , with particular attention to forest soil erosion, by using historical map and satellite images in Pohang. Our analysis revealed a dramatic increase in total vegetation cover (from 10,006.9 ha in 1918 to 17,868.7 ha in 2005) and an increase in the developed area. Meanwhile, the amount of barren mountainous area declined, shrub vegetation almost completely disappeared from the given area, and the salt marsh in the estuary completely disappeared. Mean soil loss declined from 12.6 ton ha À1 year À1 in 1973 to 0.2 ton ha À1 year À1 in 2005. A gradual landscape simplification occurred during the 90-year period. Socio-economic changes were the most important factor contributing to forest growth in South Korea. Various biological factors, including the absence of apex consumers due to their local extinction in the late 20th century, likely accounted for the rapid landscape transition. The new land management policy in South Korea resulted in the emergence of a forest ecosystem that is novel to this region and differs markedly from the historical environment, with a changed spatial arrangement of landscape elements and species assemblages.
