This study was conducted to find out the effects of over seeding using new grass varieties orchardgrass 'Kordione' and 'Onnuri', and tall fescue 'Greenmaster' on botanical composition and dry matter productivity from 2013 to 2016 in low productivity hilly pasture, middle area of Korea. There were used 3 grass seed mixture types made of different compositions and amounts {T1: control - no over seeding, T2: tall fescue (TF) 'Greenmaster' $18kg\;ha^{-1}$, orchardgrass (OG) 'Kordione' $9kg\;ha^{-1}$, Perennial ryegrass (PRG) 'Linn' $5kg\;ha^{-1}$, and Kentucky bluegrass (KBG) 'Kenblue' $2kg\;ha^{-1}$, T3: TF 'Greenmaster' $9kg\;ha^{-1}$, OG 'Kordione' $18kg\;ha^{-1}$, PRG 'Linn' $5kg\;ha^{-1}$, and KBG ' Kenblue' $2kg\;ha^{-1}$, T4: TF 'Greenmaster' $9kg\;ha^{-1}$, OG 'Onnuri' $18kg\;ha^{-1}$, PRG 'Linn' $5kg\;ha^{-1}$, and KBG 'Kenblue' $2kg\;ha^{-1}$}. In the botanical composition of grassland, T1 nearly remained constant in other seasons while ratio of weeds were increased in summer season. T2 was better than control (T1) in portion of grass ratio, which has increased by 80%. In the early time of establishment, the portions of OG were increased in T2, but TF rate was increased after 3 years later when grass was established. T3 and T4 showed a very similar patterns, grass ratio had increased by 80% and the portion of KBG had increased as time passed. T2 ($129,763kg\;ha^{-1}$) was showed the highest dry matter yield than other treatments (T1: $6,756kg\;ha^{-1}$, T3: 9641, and T4: 10,738) in 2016.

The purpose of this study was to suggest the possibility of utilizing the wildflower pasture for promoting public interest. Growth characteristics, botanical composition, fauna distribution on wildflower pastures were observed. The experimental design included two treatments: native wildflower pasture(NWP, turf grasses 6 species + native wildflower 11 species) and introduced wildflower pasture(lWP, turf grasses 6 species + introduced wildflower 9 species). The field trials were carried out on the experimental pasture plots at Chungnam National University from 1997 to 2000. The results obtained are as follows: 1. The flowering of wildflower was maintained continuously from May to September, and the colors of wildflowers; varied seasonally during this period. With native flowers, however, Hemerocallis fulva, Belamcanda chinenis and Aster koraiensisi showed problems in lately germination and early establishment. Meanwhile, Introduced wildflower showed not only excellent germination and early establishment compared to native flowers species but also maintained brighter colors. But Coreopsis tinctoria, Achillea mi/lefolium and Rudbeckia bicolor had colonized at a higher height or possessed stronger rhizome. 2. The appropriate species of turf grass which maintained continuous seasonal distribution are thought to be tall fescue, perennial ryegrass. Kentucky bluegrass in NWP and IWP. 3. Botanical composition of wild flower in NWP was arranged in the order of Achillea sibirica > Lotus corniculatus var. Japonicus > Dianthus chinensis > Plantago asiatica > Taraxacum pla~ycarpum > Viola mandshurica > Aster koraiensis > Vicia tetasperma > Lespedeza stipulacea > Hemerocallis fulva, respectively. The highest seasonal distribution of native wildflower, Achillea sibirica was in spring and summer, Lotus corniculatus var. Japonicus was in autumn. Botanical composition of wild flower in IWP was arranged in the order of Achillea millefolium Coreopsis tinctoria > Silene armeria > Coreopsis lanceolata > Rudbeckia bicolor > Sanguisorba oficinalis > Centaurea cyanus > Chrysanthemum leucanthemum > Dianthus petraeus, respectively. The highest seasonal distribution of introduced wildflower, Silene armeria was in spring, Achillea millefolium was in summer, and Coreopsis tinctoria was in autumn.

This experiment was performed in order to investigate the effect of the early grazing management on the forage yield and sward composition of oversown pasture. Two levels of the grazing intensity were treated when the grasses were 15cm, 25cm, and 35cm high. It was observed that the treatment C (light grazing intensity at the 25cm grass height) increased the dry matter yield and the botanical composition of the introduced grasses and legumes. From these facts it is suggested that the early grazing management contribute to the high forage yield and good sward composition of the oversown mountainous pasture and can take the place of cutting or other methods economically.

To classify the relationship between riparian vegetation type and bird habitat, we studied the vegetation and avian species in the three streams(Anyang Stream, Gap Stream, Seom River), located in middle province. Five different vegetation types - Woodland type, Shrub type, Tall and wet grassland type, Low and dry grassland type and Cropland - were identified. The habitats of avian species were highly correlated with vegetation type. Streptopelia orientalis and Hypsipetes amaurotis were found in woodland. Both Paradoxornis webbiana and Phoenicurus auroreus were mainly found in shrub. Tall and wet grassland were preference habitats of Ixobrychus sinensis, Acrocephalus arundinaceus, while, low and dry grassland were occupied by Phasianus colchicus, Falco tinnunculus. Cropland were used as breeding and feeding sites for Egretta alba modesta, Anas poecilorhyncha, Anthus spinoletta. Distribution patterns of avian species were clearly divided by vegetation type and site characteristics in the stream.

In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter's activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

This trial was carried out to find out the degree of fodder value of different plant communities and to make the plant sociological vegetation map for all plant communities at the natural grassland of the Rehberg-Alm in the Bavarian Alps, southern part of Germany during 1982-1983. 1. Allogenic succession of the plant communities at natural grassland was much more influenced by the change of soil moisture or/and surface water than sheep grazing. 2. The plant communities at the Rehberg-Alm were Nardetum alpigenum, Poo-Prunelletum, Cirsium arvense Cirsium Vulgare-Association, Caricetum davallianae, Rumicetum alphini, Caricetum paniculatae and Disturbed lowland bog-Stand. 3. By the sheep grazing will be improved the inferior plant community of Nardetum alpigenum to the most desirable Poo-Prunelletum plant community at the mountainous grassland gradually. 4. General fodder value in this area depended heavily on the composition of vegetation of the plant communities. The highest fodder value was the Poo-Prunelletum with 4.4 and the next was the Nardetum alpigenum with 2.5. The others were not suitable for grazing pasture due to less fodder value.
