“…Spatial distributions and temporal changes of key arboreal taxa from Asia have been investigated, for example, Abies / Picea, Pinus, Betula, Quercus and Ulmus in China north of the Yangtze River (Ren and Beug, 2002; Ren and Zhang, 1998); Picea on the Loess Plateau (Zhou and Li, 2012); and Alnus, Pinus (Diploxylon) and Quercus on the southern Korean Peninsula (Yoon et al, 2011). Furthermore, Ren (2007) studied forest-cover changes in China north of the Yangtze River during the Holocene using a 40% threshold of arboreal pollen to map the forest-steppe boundary.…”

Furthermore, Ren (2007) studied forest-cover changes in China north of the Yangtze River during the Holocene using a 40% threshold of arboreal pollen to map the forest-steppe boundary. However, the restricted spatial extent of the study areas means that these pioneering pollen-mapping studies are unable to provide a comprehensive picture of past vegetation changes beyond a regional scale.

“…Increasing temperature and humidity during the early Holocene induced upward migration of species from hornbeam and oak woodlands [22] , resulting in reduction or total disappearance of coniferous forests and arctic-alpine tundra vegetation from most Korean mountains as they do not reach sufficiently high elevations. This transition from late-glacial open conifer woodlands to mid-Holocene closed-canopy oak-hornbeam forests was a major environmental change, which probably had a significant effect on biodiversity.…”

Plant Diversity Changes during the Postglacial in East Asia: Insights from Forest Refugia on Halla Volcano, Jeju Island

Understanding how past climate changes affected biodiversity is a key issue in contemporary ecology and conservation biology. These diversity changes are, however, difficult to reconstruct from paleoecological sources alone, because macrofossil and pollen records do not provide complete information about species assemblages. Ecologists therefore use information from modern analogues of past communities in order to get a better understanding of past diversity changes. Here we compare plant diversity, species traits and environment between late-glacial Abies, early-Holocene Quercus, and mid-Holocene warm-temperate Carpinus forest refugia on Jeju Island, Korea in order to provide insights into postglacial changes associated with their replacement. Based on detailed study of relict communities, we propose that the late-glacial open-canopy conifer forests in southern part of Korean Peninsula were rich in vascular plants, in particular of heliophilous herbs, whose dramatic decline was caused by the early Holocene invasion of dwarf bamboo into the understory of Quercus forests, followed by mid-Holocene expansion of strongly shading trees such as maple and hornbeam. This diversity loss was partly compensated in the Carpinus forests by an increase in shade-tolerant evergreen trees, shrubs and lianas. However, the pool of these species is much smaller than that of light-demanding herbs, and hence the total species richness is lower, both locally and in the whole area of the Carpinus and Quercus forests. The strongly shading tree species dominating in the hornbeam forests have higher leaf tissue N and P concentrations and smaller leaf dry matter content, which enhances litter decomposition and nutrient cycling and in turn favored the selection of highly competitive species in the shrub layer. This further reduced available light and caused almost complete disappearance of understory herbs, including dwarf bamboo.

“…The appearance of Pinus pollen at this site, however, is disputable. Yoon (2012) and Park and Yi (2008) both noted a change from early Neolithic deciduous broad-leaved forest to coniferous-deciduous mixed forest from the middle-Neolithic onwards. In particular, Alnus japonica and Quercus serrata dominated in the early stage of the Neolithic, while Pinus densiflora had spread by later stages.…”

“…The results of palynological analysis can be matched with previously established hypothesis of the extensive environmental reconstruction. Data on the Neolithic vegetational conditions of Chungcheongnam Province where the Daepyeongri site belongs to, were previously presented by Yoon (2012), who constructed a Holocene isopollen map for Korea. In even earlier work, Park and Yi (2008) noted that the flora of the Korean peninsula has changed from deciduous broad-leaved forest in a cool and temperate climate in the early stage of the Neolithic to coniferous-deciduous mixed forest since the middle-Neolithic onwards.…”

Large-scale excavations between 2012 and 2015 at the Daepyeongri site on the floodplain of the River Geumgang have revealed the presence of an ancient complex settlement comprising houses, extensive agricultural fields, and pits that have been dated to between the Bronze Age and the early Three Kingdoms periods. The beginning and end of the occupation of this site and land-use patterns are assumed to have been associated with its natural environment. The pollen records presented in this study show that wet conditions continued throughout the time that this site was occupied, evidenced by the consistent appearance of Alnus, while there are nevertheless hints of some land reclamation from the Bronze Age onwards. More intensive agricultural activities that took place during this later period are evidenced by an increase in the abundance of NAP pollens related to cultivation including Gramineae, Cyperaceae, Bistorta, Compositae and Fagopyrum. At the end of the occupation period, an abrupt transition to wetter conditions is recognized while dry land condition had been prevalent for some time in other parts of the site. Microscopic examination of buried cultivated soils that evidence multiple phases of ancient field systems has enabled the identification of pedological traces of discrete cultivation patterns and shows that they changed over time. The recognition of micro-structures and associated features shows that seasonally flooded wetland was first utilized during the early phase (the Bronze Age), and that more intensified irrigation management was seen during the late phase (the time span encompassed by the proto-Kingdoms and Three Kingdoms periods). These data reveal evidence for intensive hydromorphic degradation and enable a robust recognition of settlement history and an enhanced understanding of the intensity of various land-use patterns, and landscape changes from both environmental and archaeological perspectives.
