After UNFCCC COP-21, the global society agreed to acknowledge various forms of international carbon crediting mechanisms, and noted the significance of greenhouse gas emissions reduction for sustainable development and environmental integrity through the Paris Agreement. Moreover, the agreement encouraged both REDD+ activities in developing countries and supports from developed countries. Additionally, co-benefits of forest carbon projects are important for credit transaction in the global voluntary carbon market. Under the new climate regime, co-benefits of forest carbon projects are expected to gain attention in the carbon market. To promote the social, economic, and environmental co-benefits of forest carbon projects, the introduction of an objective co-benefit assessment and certification system should be reviewed at the national level. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Successful forest greening aligned with economic growth implemented by Korea is considered best practice in most developing countries. However, the specific technologies used for this greening process in Korea have been insufficiently described. In this study we extensively reviewed papers published in academic journals and related documents regarding greening projects. We identified significant contributions from five technological areas related to forest greening in accordance with policies: (1) forest survey and inventory; (2) tree improvement; (3) seeds and nurseries; (4) tree planting and tendering; and (5) forest pest control. In conclusion, the forest greening of Korea has been successfully achieved through a combination of investment in forest protection with a well-equipped technological base that has helped us select suitable species, prepare seedlings, and plant and nurture the trees properly. Meanwhile, we also found that official development assistance (ODA) from the international community contributed significantly to the greening activities of Korea to overcome technical and economic limitations. Thus, based on the successful example of forest greening in Korea, to restore degraded forests in developing countries a systemized ODA should be provided to support the development of a scientific and technological base for developing countries. © 2017 The Author(s).

Understanding biodiversity patterns and the underlying drivers along environmental gradients is a central topic in ecology and biogeography. Despite intensive research devoted to the topic, it is poorly known how the diversity components (α-, β- and γ-) are forming the diversity patterns along gradients and whether they differ when taking individual life forms into account. In the present study, we evaluated α-, β- and γ-diversity for all, woody and herbaceous plants in relation to regional area, topographic heterogeneity, vegetation type diversity, climate and primary productivity along an extensive elevation gradient in the temperate forests of South Korea. We also examined the effect of latitude on the diversity patterns. We found differences in patterns among the diversity components as well as life forms. Habitat heterogeneity, represented by topographic heterogeneity and vegetation type diversity, was the most important driver of α- and γ-diversity, and the combined effects of habitat heterogeneity and climate were important for β-diversity of the individual life forms. Diversity patterns did not show significant relationships with latitude. Our results suggest that diversity patterns may differ among diversity components and life forms, and that habitat heterogeneity and climate along an extensive temperate elevation gradient are important biodiversity drivers in South Korea. At the same time, the effect of the elevation gradient may not be paralleled in relation to the latitudinal gradient, and this fact deserves attention in future studies. © 2016 Institute of Botany, Academy of Sciences of the Czech Republic

Understanding patterns of biodiversity and their drivers along environmental gradients is one of the central topics in ecology. However, whether diversity patterns along environmental gradients differ among diversity components as well as life forms and what kind of variables control or interact to shape the diversity patterns are poorly known. This study scrutinized the distribution patterns of three plant groups with four diversity indices and evaluated the effects of regional area, topography, topographic heterogeneity, climate, primary productivity, vegetation structure diversity and vegetation type diversity along an extensive elevational gradient on the Baekdudaegan Mountains in South Korea. Different elevational patterns, including hump-shaped, reversed hump-shaped, increasing, multimodal and no relationship, were observed among both the diversity indices and the plant groups. Regional area, habitat heterogeneity and climate were included to explain most of the elevational diversity patterns. In particular, habitat heterogeneity was the most important variable for explaining the patterns of diversity. The results suggest that patterns of elevational diversity may differ not only among plant groups but also among diversity indices and that such patterns are primarily caused by habitat heterogeneity in the Baekdudaegan Mountains because more heterogeneous and diverse habitats can support more coexisting species. © 2016 by the authors.

In fragmented landscapes, ecological processes may be significantly influenced by edge effects, but few data are available for edge effects across forest–farmland edges. We investigated patterns of species richness, abundance, and species composition in ground beetles across forest–farm edges in two different agro-forest landscapes in Korea. Nine and five sites were selected from Hwaseong, a fragmented landscape, in 2011 and 2012, respectively, while eight sites were selected from Hoengseong, a relatively well-protected landscape, in 2012. Ground beetles were collected by pitfall trapping. Species richness was higher in the surrounding habitat than in the forest interior or edge in both Hwaseong and Hoengseong. However, in Hwaseong, species richness of the forest edge was similar to that of the forest interior, while in Hoengseong forest edge species richness was intermediate between that of the forest interior and surrounding areas. In addition, non-metric multidimensional scaling based on the combined data of both locations showed that the species composition of ground beetles in the forest edge was more similar to that of the forest interior than the surrounding areas, although some open-habitat species occurred at the forest edges. Three characteristic groups (forest specialists, edge-associated species, and open-habitat species) of ground beetle species were detected by indicator value analysis. In our study, ground beetle assemblages differed in the forest edges of two agro-forest landscapes, suggesting that the edge effect on biota can be influenced by landscape structure. © 2016 The Ecological Society of Japan

Traditional field methods for measuring tree heights are often too costly and time consuming. An alternative remote sensing approach is to measure tree heights from digital stereo photographs which is more practical for forest managers and less expensive than LiDAR or synthetic aperture radar. This work proposes an estimation of stand height and forest volume(m3/ha) using normalized digital surface model(nDSM) from high resolution stereo photography(25cm resolution) and forest type map. The study area was located in Mt. Maehwa model forest in Hong Chun-Gun, South Korea. The forest type map has four attributes such as major species, age class, DBH class and crown density class by stand. Overlapping aerial photos were taken in September 2013 and digital surface model(DSM) was created by photogrammetric methods(aerial triangulation, digital image matching). Then, digital terrain model (DTM) was created by filtering DSM and subtracted DTM from DSM pixel by pixel, resulting in nDSM which represents object heights(buildings, trees, etc.). Two independent variables from nDSM were used to estimate forest stand volume: crown density(%) and stand height(m). First, crown density was calculated using canopy segmentation method considering live crown ratio. Next, stand height was produced by averaging individual tree heights in a stand using Esri's ArcGIS and the USDA Forest Service's FUSION software. Finally, stand volume was estimated and mapped using aerial photo stand volume equations by species which have two independent variables, crown density and stand height. South Korea has a historical imagery archive which can show forest change in 40 years of successful forest rehabilitation. For a future study, forest volume change map(1970s-present) will be produced using this stand volume estimation method and a historical imagery archive.

Ant assemblages in the soil have been studied at eight forest sites (4 oak forest sites, and 4 pine forest sites) in four study areas (1 seminatural area, and 3 industrialized areas) in South Korea for 6 years from 2002 to 2010. Soil cores and Tullgren funnel were used for the ant survey. Ant surveys were carried out once per year in autumn (from late September to mid-October). The soil pH was lower in the industrialized than in the seminatural area, showing the acidified soils in the industrialized areas. However, the soil acidification did not influence the ant assemblages. The results from the nonmetric multidimensional scaling ordination and from the community temperature index values indicate that temperature is a key determinant for structures of the soil ant assemblages. The ant assemblages were not different according to the forest types (oak forests vs. pine forests). Occurrence of ant species varied greatly among years, indicating that more replicates and advanced sampling method are needed for the monitoring of the soil ant assemblages.
