Restoration ecology is undergoing rapid growth as academic field over the last 15 years. The specification of goals for restoration projects is frequently described as the most important component of a project. The endeavor for universal development of goals for ecological restoration continues to generate many discussion and controversy. I discuss the importance of restoration goals and diverse roots of restoration ecology, and show how the complex lineages within restoration ecology. I review the three major theme that currently are used to develop the restoration goals : restoration of species, restoration of whole ecosystem or landscapes, and the restoration of ecosystem services. Restoration ecology, landscape ecology and conservation biology share goals to conserve biodiversity, but differ in focus of approach. I review the differences among three fields. Conservation biology has been more zoological, more descriptive, and theoretical, and more emphasized the population and genetic research. However, restoration ecology has been more plant ecological, more experimental, and emphasized the community and plant succession. Landscape ecology has emphasized the interaction of ecosystem and dispersal among populations. I suggest the integration of restoration ecology, landscape ecology and conservation biology. For example, conservation biology will contribute to the preservation of original habitats by population study, restoration ecology will contribute to regenerate damaged ecosystem and ex situ preservation, and landscape ecology will contribute to restoration of population and landscape.

The healing tourism has been growing rapidly in Korea. This study examines the restoration experience of rural healing tourism by qualitative method. The restoration environment is based on nature, and rural areas are the representative places for nature-based tourism. Therefore, this study aims to explore the meaning of restoration experiences of rural healing tourism. An in-depth interview process was used as the primary qualitative research method for this study. Nine interviews were given and from a thematic analysis of the data, six themes of restoration environments were emerged. The restoration environment of the rural settings are as follows; being away, fascination, extent, compatibility, healing nature, and leisure activity. Attention restoration theory provides a model that helps explain the results of this study. The results of this study can be useful for establishing effective marketing strategies through understanding the restoration environment in rural healing tourism.

The purpose of this study is to investigate the elementary school teachers' perception about the aquatic ecosystem restoration and confirm their ideas about factors for successful restoration and the effective direction of education for the aquatic ecosystem restoration. In order to analyze teachers' thoughts about the aquatic ecosystem restoration, in-depth interview was conducted to three elementary school teachers. Then, answers of them were transcribed and analyzed by similarities and differences among subjects. The results are as follows. Elementary school teachers thought about aquatic ecosystem restoration was divided into rehabilitation and remediation. They recognized that factors for successful restoration are the restoration to natural conditions, providing persistent benefit to local residents, and the participation of local community in the process of restoration. Teachers think that they must have correct knowledge and perception regarding the aquatic ecosystem restoration. They also think that contents about the aquatic ecosystem restoration should be taught in elementary school. They mention that they may leach students about the aquatic ecosystem restoration in discretionary activities class and extracurricular activities class. They also mention that the education for aquatic ecosystem restoration might be handled within diverse subjects.

Rapid population growth and land use changes have severely degraded streams across the United States. In response, there has been a surge in the number of stream restoration projects, including stream restoration for mitigation purposes. Currently, most projects do not include evaluation and monitoring, which are critical in the success of stream restoration projects. The goal of this study is to review the current status of assessment methodologies and restoration approaches for streams in Virginia, with the aim of assisting the restoration community in making sound decisions. As part of the study, stream restoration projects data from a project in Fairfax County, Virginia was assessed. This review revealed that the stream assessment methodologies currently applied to restoration are visuallybased and do not include biological data collection and/or a method to incorporate watershed information. It was found from the case study that out of the twenty nine restoration projects that had occurred between 1995 and 2003 in Fairfax County, nineteen projects reported bank stabilization as a goal or the only goal, indicating an emphasis on a single physical component rather than on the overall ecological integrity of streams. It also turned out that only seven projects conducted any level of monitoring as part of the restoration, confirming the lack of evaluation and monitoring. However, Fairfax County has recently improved its stream restoration practices by developing and incorporating watershed management plans. This now provides one of the better cases that might be looked upon by stakeholders when planning future stream restoration projects.

The purpose of this study was a biota research and analysis for Close-to-nature stream restoration planning of Shinchun. The summary of this study is as follows; 1) The vascular plants in research area recorded of 45 species and insect fauna recorded of 34 species of 8 orders. As a result of table of community classification, the communities were two group; Quercus variabilis community(I), Pinus densiflora-Quercus variabilis-Quercus dentata community(II). 2) As a result of analysis on correlation of tree species, the level of significance in positive correlation between Quercus dentata and Corylus heterophyll aindicated 1% and between Pinus densiflora and Lespedeza bicolor also indicated 1%. 3) As a result of DBH analysis, it is expected that Quercus variabilis and Quercus dentata will dominateover other species in competition and its succession continuously maintains from now on in community I. In community II, it is assumed that there is a high possibility of changing into community of Quercus such as Quercus mongolica, Quercus dentata, and Quercus variabilis. 4) As a result of analysis on insect fauna, insect fauna consists of 94% of whole species as 32 species, 23 families, 8 orders. And 7 species, 7 families 4 orders was found in highly urbanized area, the vicinity of Sang-Dong bridge. 5) As mentioned above, Based on A biota fundamental research, Close-to-nature stream restoration planning were full of suggestions: i) Designating ecosystem preservation area, ii) Making Close-to-nature stream revetments, iii) Making pool-and-riffle, vi) Making decks for observation and walks for nature experience, v) Creating wetland biotope. Through these methods, it is necessary to promote bio-diversity and lead people to the space for eco-learning.

As the imports of foreign agricultural products are liberalized and the consumption of agricultural products declines, abandoned rice paddy fields continues to rise. However, such abandoned rice paddy fields has not been precisely surveyed yet. In this backdrop, a necessity to develop technology to utilize such abandoned rice paddy fields has emerged. Utilization of abandoned rice paddy fields as wetlands may be a good example. This study aimed to survey the current status and characteristics of wetlands created within abandoned rice paddy fields by selecting abandoned rice paddy fields throughout the nation and conducting field surveys on the sites that had transformed into wetlands. The abandoned rice paddy fields almost transformed into wetland and the types of wetlands transformed from abandoned rice paddy fields were mainly Inland/Moutain/Depression/Abandoned rice paddy fields/Marsh/Phragmites communis community and Inland/Moutain/Depression/Abandoned rice paddy fields/Swamp/Salix koreensis community. Abandoned rice paddy fields that had transformed into wetlands was depending heavily on waterways for water supply than other reservoirs and lakes do. Abandoned rice paddy fields transformed into wetlands was most observed in mountainous area. Abandoned rice paddy fields are because agricultural land is no longer profitable due to international and social changes and is not cultivated as government policy. Wetland period and dimension originated from abandoned rice paddy fields are very various and its surrounding land its mostly forest and the next largest follow roads and rural community. The abandoned rice paddy fields transformed into wetlands is mostly deserted currently. Despite their value as wetlands, no restoration and utilization efforts are made in Korea today. Therefore, it is imperative to conduct a precise current status survey on these areas and introduce management and restoration plans at the government level in the case of important habitats.

The present studwas undertaken to classify and describe the riverside vegetation around Hanchon (36°27’-36°51’N, 128°15’-128°37’E), a tributary in the upper stream area of Nak-tong River, South Korea by methods of the ZM school of phytosociology. As a result the vegetation was divided into twenty three associations and communities belonging to ten classes. Reflecting various human impacts in the past, the associations and communities of the Artemisietea principis were most plentiful there. The vegetation units obtained in the present study were as follows: A. forest vegetation A-1 Fagetea crenatae:Zelkova serrata community, Larix leptolepis community; B. Shrub vegetation B-1 Salicetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea multiflorae:Stephanandra incisa community, Lycium chinense community; C. Grassland vegetation C-1 Lemnetea minoris:Spirodela polyrhiza-Lemna paucicostata community, C-2 Bidentetea tripartiti:Polygonetum thunbergii, Polygonetum sieboldii-hydropiperis, Panico Polygonetum hydropiperis, Pharagmitetea :Oenantho- Phalaridetum arundinaceae, Phragmitetum japonicae, Miscanthetum sacchariflori, Phragmites australis community, C-4 Artemisietea principis:Artemisia princeps community, Impatiens textori community, Lactuco indicae-Humuletum japonicae, Pueraria lobata-Humulus japonicus community, Pennisetum alopecuroides community, C-5 chenopodietea:Echinochloa crus-galli var. orizicola community, Digitaria adsecendens community, Polygonum nodosum community, C-6 Miscanthetea sinensis: Miscanthus sinensis community, C-7 Plantaginetea:Eragrotis multicaulis-Plantago asiatica community. It is inferred that the endemic vegetation units in the riverside vegetation of Korea are very rare, because most of the vegetation units obtained in the present study are common with those of Japan. Among the above vegetation units, the Salicetum graciliglandis was established as a new association. On the other hand, the associations and communities of classes characterizing the riverside vegetation increased with a decrease of human impacts from the downstream to the upstream in Hanchon, while the number of the naturalized plants was the reverse. Also based on the present phytosociological work, the relation between the vegetation units and their environmental conditions and the restoration ecology and nature conservation of the riverside vegetation were discussed here in detail.

This study was carried out in each three study areas of Pinus densiflora community and Quercus mongolica community from March 5th, 2008 to October 15th, 2010 to analyze the relationship between seed bank and the actual vegetation of the lower layer. Based on the relationship between the lower layer of actual vegetation and the germination of seed bank, all of three study areas, the similarity of the actual vegetation of the lower layer and seed bank were high in Plot 1 (84.62%) and Plot 3 (89.91%). As for Quercus mongolica community, the similarity was high between the actual vegetation of the lower layer and seed bank in Plot 4 (82.24%) and Plot 6 (89.47%). Especially, the germination of the pine seed banks in the Pinus densiflora community compared to other tree species appeared in all. In Quercus mongolica community, Quercus mongolica did not appear among the seeds germinated in the seek bank, but the other tree species constituting the under layer of the community. In case of the restoration based on the actual vegetation, it is desirable to sue the lower layer of vegetation as the model for the making of its alternatives for restoration works of the species.
