We present a planting plan of the buffer-forest belts created at the boundary area of the waste landfill site which is located in the coastal area of Kyubg-Gi province. In order to form a proper section of ground soil excavated from the sea and a forest which shows a distinction of the vegetation stratification, the planting plan with trees, sub-trees, shrubs, and seedlings (produced at a sprout cultivation place) is devised with an adjustment of planting density. 1. The preparation of mounding is required for planting at a waste landfill site. We first estimate an economical and efficient banking height together with the quantity of soil, and prepare a planting ground with excavated ground soil for the consideration of soil recycling. On the planting ground a banking with a height of 1.5-2m is produced by self-supported soil, playing a role in a salt blocking and an irritation layer of planting. Finally, an additional banking with a height of 2m is produced by qualified vegetation soil, forming a vegetation section with a total height of 6m. 2. Since the planning site is located in the border, the planting area is composed of two regions : one is an inclined face (slope 1 : 3) toward the inside of the landfill site and the other is an inclined face (slope 1 : 4) toward the inland. The buffer planting in the former (latter) region consists of wind break forest (mixed-landscape forest) within a width of less than 35m. 3. Based on the data obtained from the literatures and the investigation of local plants, we choose the 21 plant species (such as Pinus thunbergii, Pinus densiflora, Sorbus alnifolia, Albizzia julibrissin and etc.) and the additinal 7 species which are grown at a sprout cultivation palce of the SUDOKWON landfill site (Rosa rugosa, Quercus acutissima, Prunus armeniaca var. ansu., and etc.). Sub-trees with a height of above 2.5m and seedlings are planted with an interval of $1.5{\times}1.5m$ ($0.45roots/m^2$) and $0.5{\times}0.5m$ ($4roots/m^2$), respectively. Here, both trees exhibit communities planting with more than three rows. Shrubs are planted with $9-16roots/m^2$, depending on their size. Since this case study provides a reference of the planting beds as well as a planting plan at the SUDOKWON landfill site, it is not sufficient for the present plan to be utilized for the formation of buffer-forest belts which are used for the analysis of environmental factor and the reduction of environmental pollutants in the sea waste landfill site. Thus, further studies with the ecological basis are demanded for the environment planting restoration in the sea waste landfill site.

The objective of this study was to find optimal planting season of the effect of vegetation competition around planting tree. This study evaluates the possibility of extending the planting period of containerized seedling of Pinus densiflora (1-0 year). We planted seedling at three different seasons (spring, summer, fall) at 18 plots in 3 locations. Planting sites were composed of vigorous vegetation (Site A) and less vigorous vegetation (Site B). For over 3 years, the study investigated survival rate, growth of root collar diameter and height, and biomass of containerized seedling of P. densiflora. In all sites, containerized seedling of P. densiflora showed high survival rate in summer planting. Height and root collar diameter of containerized seedling of P. densiflora were the highest in summer planting, but in the initial period after planting growth was not good. After time passed, growth rate was increased. Site B showed better growth than Site A. Biomass was the highest in summer planting and also the highest in Site B. These results suggest that planting period can be extended by using containerized seedling and vegetation control in the initial is very important for survival and growth of containerized seedling.

Background: In the Philippines, the practice of planting mangroves over seagrass has been a practice done to promote coastline protection from damages done by storms. Despite the added protection to the coastline, the addition of an artificial ecosystem gradually inflicts damage to the ecosystem already established. In this study, seagrass communities that had no history of mangrove planting were compared with those that had mangrove planting. The percent substrate cover of seagrass in the sampling areas was determined, and the macroinvertebrates present in the sampling areas were also observed. The study was conducted based on reports of mangrove planting activity that disrupted seagrass functions on Santa Fe, Bantayan Island, Cebu. Transect-quadrat method sampling was done to assess the chosen sites. Results: Six species of seagrass was found on the site without mangrove planting which was barangay Ocoy (Cymodocea sp., Thalassia sp., Halodule sp., Enhalus sp., Halophila sp., and Syringodium sp.) and had a higher percent cover, while only four were found on the site with mangrove planting (barangay Marikaban). It was also found that barangay Marikaban had a lesser Shannon-Wiener and Simpson's index compared to barangay Ocoy. Jaccard's index of similarity between the two sites was low. Conclusion: With the results of the assessment, we recommend proper monitoring of future mangrove planting activities and that these activities should not disrupt another ecosystem as all ecosystems are important.

We have analyzed the effect of planting site (elevation) and direction of fruiting on the frost damage (tolerance to transparent skin and blemishes) of persimmon (Diospyros kaki Thunb) 'Fuyu' fruit subjected to the early fall frost (November 2, 2012) in environment-friendly orchards of Changnyeong and Changwon (Gyeongsangnam-do Korea). In Changnyeong, the direction of fruiting showed a significant effect on the fruit weight and the fruit width (p<0.01), and the fruit firmness (p<0.05) while the planting site (elevation) did a highly significant effect on the fruit width and the frost damage (p<0.01), and fruit length (p<0.05). In particular, severe frost damage of fruit (15.2%) and leaves (about 90%) was observed in the plants located in the low elevation area of orchard. The damaged fruit had an transparent skin color and/or blemishes. In Changwon, there was no effect of the planting site and the direction of fruiting on the frost damage, and the fruit characteristics except the fruit width having been related to the planting site (p<0.05). So, the main effects for the fruit frost damage was a terrain factor around the orchards.

The growth conditions of planted trees, invasion of nuisance herbaceous species, competition between species, and effects of erosion control were monitored over five years in a riparian greenspace in Gapyeong County that was established through multilayered and grouped ecological planting. Of 156 trees planted in the upper and middle layers, 5.8% died. This tree death was attributed to poor drainage or aeration in the rooting zone from the clay-added root ball and too deep planting as well as a small-sized root ball and scanty fine roots. Of all the trees, 21.6% grew poorly due to transplant stress in the first year after planting, but they started to grow vigorously in the third year. This good growth was largely associated with soil improvement before planting, selection of appropriate tree species based on growth ground, and control of dryness and invasive climbing plants through surface mulching and multilayered/grouped planting. Mixed planting of fast-growing species as temporary trees was desirable for accelerating planting effect and increasing planting density. Thinning of fast-growing trees was required in the fifth year after planting to avoid considerable competition with target species. To reduce the invasion of herbaceous and climbing plants that oppress normal growth of planted trees, higher density planting of trees (crown opening of about 15%), woodchip mulching to a 10-cm depth, and edge planting 2 m wide were more effective than lower density planting (crown opening of 70%), no surface mulching, and no edge planting, respectively. This reduction effect was especially great during the first three years after planting. Nuisance herbaceous plants rarely invaded higher density planting with woodchip mulching over the five years. Higher density planting or woodchip mulching also showed much greater erosion control through rainfall interception and buffering than lower density planting with no mulching did. Based on these results, desirable planting and management strategies are suggested to improve the functions of riparian greenspaces.

The purpose of this study was to propose the community planting method through analyzing the plant community structure of three green space types and the relationship of vegetation and wild bird inhabitation of urban environmental forest in Seoul, Korea. The results from this study showed that the vegetation stratification, coverage, and species diversity were closely related to the wild bird inhabitation. In addition, the environmental forest in study site was analyzed as a negative factor that may decrease the biodiversity. Therefore the ecological structure and environmental condition must be considered in order to improve the quality of environmental forest. Based on results in three green space types, the planting species, density and species size for proper community planting were proposed in this study. The ecological niche relationships among sixteen selected species were also presented. The results will be provided as an valueable output for the completed community planting of urban green space in the central region, Korea.

This study is focused on the groping for the alternative ways in order to prevent the various bad factors caused by the Inferior environment on the planted trees. In the reclaimed paddy field which is planned to make a housing site, for example, we are trying to catch the problem about the special feature of the unharmonized drainage. And the survey gives the suitable way of planting trees. This survey was carried out in the three different area and could notice some phenomena : There are a few different conditions for water supply int\ulcorner the soil according to the height of the land-filling from the original ground and the slope of the planting area. And the imporant factor of the drainage effect is not the soil texture itself but the depth of the filling land. As a result of this survey, the study shows the economic alternative for reducing the demage of the planting trees which is due to drainage system.

This paper presents eco-friendly planting method to overcome the problems of existing concrete retaining wall and gabion retaining wall, respectively, based on the examination on existing concrete and gabion retaining wall. Prior to doing this, proper design method was provided through pull out test. Planting method using gabion metal net and L shape green net retaining wall were compared and analyzed. According to this study, it is confirmed that reduction of construction period and economical profit in construction can be achieved by both manufacturing at the factory and self procurement at the job site as well as the use of metal net, which is applied as a substitution of existing strengthening material. For the effect of planting method, the use of L shape green net retaining wall shows superiority to environment-friendly gabion retaining wall in its ability to rootage and germination of the grass. The L shape green net retaining wall had excellent performance in helping rootage of grass and prevention of soil leakage, and even if raining period, remarkable damage of planting mat does not occur when planting mat is applied.

In this study, in order to examine the change of soil animals by vegetation restoration types, experimental sites with biotope restoration method, forest topsoil paving method, small diameter trees planting method and multi-layer community planting method were applied and the control site was selected. The naturalness of soil animals was analysed by studying the change of soil animals. It was confirmed that the control site has a high level of the naturalness of soil animals as it includes a mixture of fauna sensitive and insensitive to environment distributed widely over the site. The experimental site with biotope restoration method showed a similar level of the naturalness of soil animals as the control site. Furthermore, the naturalness of soil animals in the experimental sites with small diameter trees planting method and multi-layer community planting method also showed a progressive restoration although the level of the naturalness of soil animals is lower than the experimental site with the biotope restoration method. Therefore, it is confirmed that the experimental site with biotope restoration method shows a faster recovery of soil animal than other sites. This is because this method uses the portion of topsoil and subsoil that were dug from the intact forest during transplantation.
