This study was conducted to find out the growth characteristic of mixed-seeding in the grasses for slope revegetation measures. Seeding treatment with six combination types of five grasses used for this experiment such as orchardgrass(Dactylis glomerata 'Potomac'), perennial ryegrass(Lolium perenne 'Manhattan'), tall fescue(Festuca arundinacea 'Jaguar'), kentucky bluegrass(Poa pratensis 'Majestic') and weeping lovegrass(Eragrostis curvula). The growth of orchardgrass, perennial ryegrass and tall fescue were good on mixed-seeding condition in case of number of individuals, heights and coverages at this experiment. These plants will useful for revegetation measures mixed-seeding, but weeping love grass and kentucky bluegrass did not show a desirable growth in mixed-seeding condition, and these plant prefered mixed seeding to single seeding. Regeneration percents of orchardgrass, perennial ryegrass and tall fescue were higher than that of weeping love grass and kentucky bluegrass, and coverage kept on good condition through one year after seeding, therefore, these plants will effective for initial stage revegetation measures.

Riparian vegetation gives basic habitats for animal and other biological organisms. It is one of essential landscapes in river ecosystem. This floral study was conducted to give basic information for management of the Geum river ecosystem. We discovered total 69 plant communities out of 40 sites studied and mean 8 plant communities were analysed per study site. Salix koreensis and Salix subfragilis community were dominant of all communities at tree layer and Salix gracilistyla and Rubus parvifolius were dominant communities at shrub layer. Phalaris arundinacea, Phragmites japonica, Miscanthus sacchariflorus and Artemisia princeps var. orientalis appeared most as perennial grasses and Humulus japonicus, Persicaria thunbergii and Persicaria hydropiper appeared most as annual grasses. Robinia pseudoacacia, Amorpha fruticosa and Bidens frondosa were frequently present as exotic species. Grass communities were higher than tree communities because of human disturbance by artificial banks. The number of species was 182 appeared as 53 families 144 species, 34 varieties and 4 forma and mean species number was 25.5 per site. The most abundant site was Yanggang bridge site (14 vegetation association, 49 species) and the least abundant site was Namdaechon, Muju site (3 vegetation association, 12 species). We suggest that continuous riparian vegetation monitoring should be carried out to manage water environment ecologically.

This study aimed to address problems and suggest solutions in applying seed mixture design criterior of the slope revegetation works according to "The guidelines of Slope revegetation design and construction" proposed by the Ministry of Construction and Transportation. To do this, the planting thickness was set to be the same 2cm while the composition of seeds was made different, which was planted in artificial slopes and fields. The main results were summarized as follows. In the test, when applying the provisional standards of the plant mixtures proposed by the Ministry of Construction and Transportation, tree seeds and native plants were found poor coverage effect in the early stage in all test plots due to introduced grasses. This was because introduced winter grasses which grew well in the early stage, could grow densely, so it might hamper the growth of other plants. Therefore, it was found desirable that standards for seed mixing should be adjusted down by 10% and the ratio of introduced grasses in the mixture should be lowered to 25% while native plants should increase to 20-25%.

Recently, attempts to use indigenous plants have been made for the recovery of nature of slopes and making permanent vegetation group, harmonizing with surroundings from the ecological perspective. For surface failure prevention of slopes, indigenous plants are known as superior to those of exotic grasses, but studies how much indigenous plants influence shear strength of soil is lacking. Therefore, in this study, strength increasement of the root-soil system were investigated for four indigenous plants.

The objective of this study was to determine the optimal amount and the mixture ratio of seeds for revegetation species by investigating their growth characteristics. For the purpose of the experiments, 15 plants were chosen. In May of 1995 to September of 1998, the nursery seedbeds of the College of Agriculture and Life Sciences, Seoul National University were seeded with the mixtures of those species. Then, the nursery seedbeds were treated to investigate the effects of the amount of seeding, the amount of fertilizer, and the depth of soil on the growth characteristics. As the results of the experiments, it was found that the effects of all the treatments on growth of shoots and roots were significant in the early phase. For the expected number of seedlings more than 3,000 per square meter, many seedlings got withered to death while the survivors were suppressed to grow slow in the early stage due to the density problem.

It is possible to divide the historical changes of slope revegetation in Japan into five periods as follows; 1) The early period after creation(1927-1948), 2) The spreading period of modern revegetation work with manpower(1947-1958), 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985${\dots}$), 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995${\dots}$), 5) The developing period of nature restoration technique using endemic arborous species(1996-). Recently main purpose of slope revegetation has been developing from the erosion protection to the nature restoration in the current of the 5th period. It is said that the role of the Japanese Society of Revegetation Technology(JSRT) is critical to the history of slope revegetation in Japan. 'The tentative guidelines of slope nature restoration' was announced by JSRT in 2004. In the guidelines, it was proposed that the planning techniques of using suitable seeds/plants based on the preservation level at the each construction sites. Moreover, the use of soil seed bank is the new and important study theme in the field of nature restoration. Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing. Finally, some critical concepts are necessary to develop the field of restoration in Korea as follows; 1) monitoring of constructed sites, 2) ensuring of biodiversity, 3) recognition of slow revegetation and mosaic arrangement in revegetation, 4) reuse and recycle on the construction sites, and 5) promotion of specialist.
