  • In Korea terrestrial fluvial sequences can be used as pedological and sedimentological markers indicating a millenium-scale environmental and climatic changes imprinted in fluvial sub-environments, which in turn are represented by the cyclicity of fluvial sands, backswamp organic muds, and flooding muds intercalations of frostcracked or dessicated brown paleosols. Post LGM and Holocene fluvial and alluvial sedimentary sequences of Korea are formed in such landscapes of coastal, floodplain, backswamp and hillslope areas. Among them, the most outstanding depositional sequences are fluvial gravels, sands and organic mud deposits in coastal, fluvial, or alluvial wetlands. The aim of this study is to explain the sedimentary sequences and palynofloral zones since the last 15,000years, on the basis of organic muds layers intercalated in fluvial sand deposits. Jangheung-ri site of Nam river, Soro-ri site of Miho river, Youngsan rivermouth site in Muan, Oksan-ri site of Hampyeong and Sanggap-ri site of Gochang are illustrated to interpret their sedimentary facies, radiocarbon datings, and palynofloral zonation. Up to the Middle to Late Last Glacial(up to 30-35Ka), old river-bed, flooding, and backswamp sequences contain such arboreal pollens as Pinus, Abies, and Picea, and rich in non-arboreal pollens like Cyperaceae, Gramineae, Ranunculaceae, and Compositae. During the LGM and post-LGM periods until Younger Dryas, vegetation has changes from the sub-alpine conifer forest(up to about 17-11Ka), through the conifer and broad-leaved deciduous forest, or mixed forest (formed during 16,680-13,010yrB.P), to the deciduous and broad-leaved forest (older than 9,500yrB.P). In the Earliest Holocene flooding deposits, fragments of plant roots are abundant and subjected to intensive pedogenic processes. During Holocene, three arboreal pollen zones are identified in the ascending order of strata; Pinus-Colyus zone(mixed conifer and deciduous broad-leaved forest, about up to 10Ka), Alnus-Quercus forest (the cool temperate deciduous broad-leaved forest, about 10Ka-2Ka), and Pinus forest (the conifer forest, about after 2Ka), as examplified in Soro-ri site of Cheonwon county. The palynological zonations of Soro-ri, Oksan-ri, Sanggap-ri, Youngsan estuary, and Gimhae fluvial plain have been recognized as a provisional correlation tool, and zonations based on fluvial backswamp and flooding deposits shows a similar result with those of previous researchers.

  • Traditional village forests in the Jeju Island represent unique cultural landscape with a history of more than several hundred years as a national cultural asset in Korea. There are 368 Oreums, parasitic volcanoes, and 391 shrines of Dang(Divine place) in Jeju. Currently, the shrines of Dang are damaged by the Jeju Olle trail path and road constructions. It's time for cultural consents to be obtained with locality and globality. And need to produce our own unique contents, glocal cultural contents. In this study, the establishment of trail path of Jeoji Oreum in relation to the Dang in the Jeju Island was investigated. By linking the Dangsan forest to the Jeoji Oreum trail path, it enables the path to contact with traditional cultural landscape. Rural villages in Jeju with the Oreum and Dang are expected to get an international attention as to have traditional cultural landscapes of Korea. It needs to be managed to retain their original form and in connection with the trail path.

  • This study shows that coastal sand dunes are negatively affected by coastal forests. In South Korea, planting pine trees on the dunes has been carried out to stabilize the dune landscapes and protect residential areas from coastal disasters since the 20th century. However, this strategy could reduce the resilience of dunes. In this study, we selected three monitoring sites with automated weather stations to compare the geomorphological and environmental characteristics between tree-covered and grass-covered dunes at Sohwang-ri, Boryeong-si, Chungnam Province for three years. In addition, we monitored the rates of erosion and deposition using eight pins along the dune crests. We found that the forest affected both wind velocity and direction, resulting in decreased blown sand supply to the dunes in front of the forest. The velocity of the strong winds faster than 5 m/s diminished to 10%-30% of the control sites, and the direction of northwesterly wind were skewed to the north by about 6°. Sand deposition occurred at about 15-20 m away from the pine forest and the amount was only 1/10 of the deposition within the grass-covered dunes. This study suggests that planting trees in coastal dunes is an undesirable strategy with negative impacts on the landscape management.

  • This study aims to reveal the distribution of native plants, rare plants, and specialty plants and provides basic data for efficient ecosystem management through a survey of the flora in Mt. Chijae (Gamagol) and its adjacent areas in Damyang-gun, Jeonnam-do, while also identifying useful plants in the eco-city Damyang-gun for distinctive garden plants. A total of 21 field surveys were conducted from March 2022 to June 2023 to collect and identify 492 taxa consisting of 101 families, 304 genera, 444 species, 10 subspecies, 35 varieties, and 3 formas. The analysis of the prepared sample list showed 14 taxa designated as specialty plants, 9 taxa designated as rare plants by the Korea Forest Service, 7 taxa designated as the national red (i.e., endangered) plants by the Ministry of Environment, and 68 taxa with phylogenetic specific species, of which 45 taxa for Grade I, 5 taxa for Grade II, 16 taxa for Grade III, and 2 taxa for Grade IV were confirmed. The list included 155 taxa of biological resources subject to export approval by the Ministry of Environment and 38 taxa of alien plants of which 7.7 percent were naturalized, and the urbanization index was 6.1 percent. Four taxa were ecosystem-disturbing invasive alien plants designated by the Ministry of Environment introduced artificially or naturally from abroad. This study is expected to contribute to creating unique and attractive landscapes in Damyang if the specific plants found in Mt. Chijae are grown and planted in city gardens.

  • Rural areas dominate country landscape, where the population is rich in traditional and natural heritage. Dangsan forests and Rural community forests (RCF) have been maintained by local residents for hundreds of years. However, many of these forests have been disturbed, and only small amount of Dangsan forests and the RCF remain due to the efforts of local residents. Recently, the remnants of Dangsan forests and RCF have been regarded as living traditional landscapes representing the cultural and rural background of Korea. But the value of Dangsan forests and the RCFs has not been recognized by many. This study aims to understand the characteristics and management status of Dangsan forests in Sungnam-ri, Wonju. Sungnam-ri has four villages, each of which is bordered by a Dangsan forest at the riparian buffer. Sungnam-ri has been selsected as a site for a rural village development project by the Ministry of Agriculture & Forestry of Korea. Sunghwanglim (the Upper Dangsan forest) is designated as Natural Monument No.93 and entrance is limited in this area. The size of Sunghwanglim is $21,133m^2$, and the major tree species are Kalopanax pictus (Dangsan tree, Divine tree), Pinus densiflora, Abies holophylla, Acer triflorum, Ulmus davidiana, Fraxinus rhynchophylla and Quercus serrata. In total, 124 trees with more than 40 cm in DBH are at this site. As for cultural activities, the Dangsan festival is held on April 8th and September 9th of the lunar calendar at shrines in the forests. Although other Dangsan forests are smaller than Sunghwanglim, they also have similar cultural activities. The landscape of the Dangsan forests have been managed for several hundred years by the local people, and they intend to continue maintaining the Dangsan forests for the purpose of festivals and other cultural activities. The findings in this study suggest that Dangsan forests have the potential for the development of rural villages and for the improvement of cultural and natural landscapes in Korea.

  • This paper aims to make an aesthetic inquiry into representing modes of wilderness in western films. The western film was the first genre in earnest about natural landscape, covering vast areas of America from the East to the West. It adopted representative modes suited to physical characteristics of landscapes which produced aesthetic characteristics. In western films, wilderness was represented at a distance from the camera lens as a setting and an object of contemplation. In eastern forest landscapes, western films adopted the visual model of Hudson River School's landscape painting which expressed the transcendental sublime. The western semiarid region reproduced the warrior's gaze shot from a high angle, and, in this visual mode, wilderness was expressed as a demonic landscape derived from Burke's definition of the sublime. On one hand, the western desert was represented as a place of hardship shot at a low angle which expressed the vastness, unevenness and limitlessness of the desert owing to the absence of horizon. On the other hand, the mesas of Monument Valley have sublime characteristics of size and time. In western films, they play the role of an emblem by rising from the limitless desert on the horizon. The prospect-refuge relationship, the desire to see without being seen, is discovered in the representative mode of wilderness in western films. In this context, this study hopes to discover the archetype of landscape representation.

  • Currently, bridges are regarding as the structure with formative, scenic and environmental values more than their function as simple passageways. Because an attempt to work on the diversity of the bridge types and installation of the large structures on bridge are part of the project of the regional amenity enterprises, a study that harmonizes bridges with landscape is needed at this point in time. This background can influence the direction of bridge landscapes that considers local features by analysis of visual preferences on a bridge simulated scene. The results were as follows: analyzing the change of the simulated landscape image, forest landscape are damaged by the input of a bridge which was natural, harmonic and intimate. On the other hand, when a bridge was inserted into the ocean landscape, it was thought to improve the ocean landscape, especially, upper part form of arch bridge various or suspension bridge were improved in polished and various image. The insertion of a bridge into an urban landscape change from a negative image to a beautiful, harmonic and attractive image. The intimate, harmonic and natural image of a rural landscape was damaged by inserting a bridge. As analysis result about change of landscape preference by input of bridge, there is difference between before and after as input the bridge, and bridge influences as main object in the simulated scene. Visual preference was the highest in the ocean landscape, and the lowest in the suspension bridge in the rural landscape. The complicated shape of bridge follows on the background type difference certainly appear. Thee simulated scene preference except the urban landscape of the simulated scene fell generally Especially, fall of preference of girder bridge in the forest and ocean landscape, suspension bridge in the rural landscape appeared notedly.

  • Dangsan forests had been established by local residents several hundred years ago. They were disturbed in various ways, but still remain in many villages where dangsan festivals are held every year. Although the remaining Dangsan forests represent korean rural cultural landscapes, their characteristics still remain to be uncovered. The objectives of this study were to understand the three elements, Dangsan tree (Divine tree), shrine and stone tower, and to investigate the culture at inland areas and seashore areas relation to Dangsan forests. Twenty cases of Dangsan forests at inland areas and twenty at seashore areas were investigated. There were nine shrines and six stone towers found out of twenty inland Dangsan forests. Fifteen shrines were found out of twenty seashore Dangsan forests. Stone tower was not found at seashore areas. Fifteen events of dangsan festival were investigated. Dangsan festival appeared to have played an important role to preserve Dangsan forests. Based on the findings of this study, Dangsan forests are, as landscape elements at inland and seashore areas, proved to have a potential for the improvement of cultural and natural landscapes in the country.

  • Background: Khyber Pakhtunkhwa government initiated the Billion Tree Tsunami Afforestation Project including regeneration and afforestation approaches. An effort was made to assess the distribution characteristics of afforested species under present and future climatic scenarios using ecological niche modelling. For sustainable forest management, landscape ecology can play a significant role. A significant change in the potential distribution of tree species is expected globally with changing climate. Ecological niche modeling provides the valuable information about the current and future distribution of species that can play crucial role in deciding the potential sites for afforestation which can be used by government institutes for afforestation programs. In this context, the potential distribution of 8 tree species, Cedrus deodara, Dalbergia sissoo, Juglans regia, Pinus wallichiana, Eucalyptus camaldulensis, Senegalia modesta, Populus ciliata, and Vachellia nilotica was modeled. Results: Maxent species distribution model was used to predict current and future distribution of tree species using bioclimatic variables along with soil type and elevation. Future climate scenarios, shared socio-economic pathways (SSP)2-4.5 and SSP5-8.5 were considered for the years 2041-2060 and 2081-2100. The model predicted high risk of decreasing potential distribution under SSP2-4.5 and SSP5-8.5 climate change scenarios for years 2041-2060 and 2081-2100, respectively. Recent afforestation conservation sites of these 8 tree species do not fall within their predicted potential habitat for SSP2-4.5 and SSP5-8.5 climate scenarios. Conclusions: Each tree species responded independently in terms of its potential habitat to future climatic conditions. Cedrus deodara and P. ciliata are predicted to migrate to higher altitude towards north in present and future climate scenarios. Habitat of D. sissoo, P. wallichiana, J. regia, and V. nilotica is practiced to be declined in future climate scenarios. Eucalyptus camaldulensis is expected to be expanded its suitability area in future with eastward shift. Senegalia modesta habitat increased in the middle of the century but decreased afterwards in later half of the century. The changing and shifting forests create challenges for sustainable landscapes. Therefore, the study is an attempt to provide management tools for monitoring the climate change-driven shifting of forest landscapes.

  • The Doam-dam watershed, located at Kangwon Province, Korea, has been experiencing significant changes in land uses, conversion from forest to agricultural/urban areas, with human involvements. However, no thorough investigation of the landscape impacts of land use changes was performed at this watershed using the scientific analytical tool. Thus, the FRAGSTATS model was utilized to quantitatively analyze the landscape impacts of forest fragmentation in this study. To provide the detailed explanations for 11 landscape indices considered in this study, two artificial and simplified landscapes, before and after fragmentations, were constructed. Using these 11 indices, the landscape impacts of forest fragmentation in 19 subwatersheds of the Doam-dam watershed were analyzed. The S1 subwatershed, one of 19 subwatersheds of the Doam-dam watershed, was found to have experienced the significant forest fragmentation from 1985 to 2000 based on landscape analysis using the FRAGSTATS model. The results obtained in this study can be used to evaluate the water quality impacts of forest fragmentations/land use changes at watershed scale level, and establish environment-friendly land use planning based on the results obtained using landscape analytical tool, FRAGSTATS.
