  • Pasture in woodland have been extensively established to meet the demand of forage for livestock. The survey type of study was conducted to investigate and analyze for the establishment of pasture in woodland from foresters' standpoint. The findings can be provided for basic data to achieve appropriate wooldland use pattern. The study area was confined to Pyungchang county, Hoengsung county, and Hongcheoa county, which are primary pasturing region in Kangweon province. The analysis was based on the field survey of 30 pastures (grouped to 'successful', 'failed', and 'grazing-in-the-wood' site) and returned 133 questionnaires from 398 debriefed pasture owners.

  • The purpose of this paper is to research Gunnar Asplund's Woodland Chapel (1918-20) in terms of the revernacularization of classicism and to investigate into the matter of the constructional logic. The term 'revernacularization of classicism' was used by Alan Colquhoun to explain the process to return to the pure sources of classical architecture, and the case of a successful fusion of classicism and vernacular traditions was suggested by Demetri Porphyrios through Scandinavian Doricist sensibility in the early 20th century. Porphyrios's classicism, not as style but as sensibility, is premised on a constructional logic of vernacular, and is to achieve an aesthetic quality by its mythical elaboration. Woodland Chapel, a representative of the Scandinavian Doricism according to him, illustrates characteristics of the revernacularized classicism as in the fact that it thickly displays vernacular images at the same time as relying on classicism; in the return to primitive simplicity; and in the mythopoeic power. However, the constructional logic of this building was obscured in the capital of the portico columns, the interior dome, and the whole structure of the roof. Confronting this paradox, we have to remember that although Porphyrios emphasized the constructional logic he opened an aesthetic exit of the mythical elaboration, which is in accord with the concept of the tectonic as the poetics of construction. Woodland Chapel assumes atectonic features but is never anti-tectonic. Asplund intensified a poetic effect by setting the myth over construction in the chapel, and so it can be seen as a key example of the revernacularized classicism with the Doricist sensibility.

  • Molluscs from the Neolithic shell middens (Sugari, Pudjeong, Tongsamdong, Sangnodaedo, Sandeung, Yondaedo, Songdo and Kupyongri) in the southern coast, Korea, consisted of marine, fresh-water and land molluscs. Among these, intertidal species were exploited most abundantly as food resources, indicating a high dependence of intertidal shellfish collection activities. Especially oysters were the most abundant in these sites except Tongsamdong where mussels were predominant, indicating oysters were the most important food resources. Land snails from the sites consisted of woodland and open land species. Woodland species were more abundant than openland species, suggesting that there was a woodland environmint around the sites. Marine and land mollusc species from the sites are common in these rigions today, indicating no large-scale emvironmental changes have occurred since these middens formation period.

  • In Korea, 'forest welfare' is officially included as a policy object and used as an academic term. The Korea Forest Service strives to provide a forest welfare services suitable for each life cycle from birth to death, and the public is highly aware of the need for these policies. The demand for National Woodland Burial Grounds is expected to increase as the interest in natural burials including woodland burial is increasing. As the demand for the Woodland Burial Grounds is increasing, there is only one National Woodland Burial Grounds currently available. Although other forest welfare facilities, such as natural recreation forests, must have undergone feasibility assessment according to relevant laws before approval of the designation, there are no institutions performing Woodland Burial Grounds feasibility assessments at the time. Therefore, it is necessary to consider the policies to cope with the increased demand. This study used GIS to prepare the basic data to be used in the process of selecting suitable forest locations. The area that cannot be used according to related laws was analyzed and the size of the possible areas in the state forests was assessed.

  • Surface sowing method is one of the important methods to establish seeds in mountainous area. Seed-coating technique in the surface sowing method is increasing interest in the world today. An experiment was conducted to develope a technique for pelleting seeds of grass in woodland. Results showed that the seed pelleting was a useful technique than coating seeds because the pelleting reduced coating time and increased amounts of coated seeds per hour. As lowering temperature and reducing time for drying, germinating energy and germination rate of pelleted seeds were improved. And emergence, establishment and early growth of pelleted were also improved in pasture under woodland. Based on this study, we could conclude that the seed pelleting is a useful technique for the establishment and early growth of grass under woodland.

  • This study estimated the mound and termite population density in the two study plots in Durokkopin Nature Reserve, Western Australia between 2003 and 2004. The mound density and size were greater in the woodland than in the shrubland. The annual growth rate of mounds was minimal. Some mounds decreased in volume during the 14 month observation period in both study plots. There were no significant differences in the termite population per mound or in the proportion of each caste between the two study plots. The size of the termite population in the mound progressively increased from the small to larger mounds. Overall, of the two favoured habitats, woodland appears to be more optimal for this termite species than the shrubland.

  • Although economically viable, the livestock industry is currently facing a number of challenging environmental problems and highly complex social issues, many of which are related to its size and geographically concentrated nature. Increased emphasis on environmental quality has also placed new demands on livestock producers to ensure that their production practices are in harmony with natural environment. In terms of sustainable agricultural systems, ruminants have served and will continue to serve a valuable role. They are particularly useful in converting vast renewable resources from rangeland, pasture, and crop residues or other by-product into food edible for human. With ruminants, land that is too poor or too erodable to cultivate becomes productive. Also, nutrients in by-products are utilized and do not become a waste-disposal problem. In Korea, however, native and dairy cattle production is not consistent with the advantageous roles of ruminant livestock in sustainable agricultural system because imported feed grains become the main basis for cattle raising. At present the ruminant livestock producers are heavily concentrated in and around the urban areas. About 75% of all the nation's cattle herds are kept on the outskirts of urban areas. As a result, the amount of pasture and forage land available per head of cattle is generally small. Furthermore, animals are raised in a cattle shed with high density. This situation is rather unfavorable for the national economic and environmental points of view As nation income increased, the demand for livestock products grew at an unforeseeable pace. But the pasture area involving in current utilization is tended to decrease during recent years. Based on the above figures more than 250,000 ha of pasture ought to be available for the present herd of cattle. It is obvious that these needs can scarcely be met with arable lands. Lands area for the establishment of new grassland have to be found in the hills and mountains which have not yet been used for crop framing or livestock. The development of extensive grasslands in the hill and woodland areas is now a declared aim. The starting point of the present work is the lack of knowledge of forage production and utilization in hill pasture and woodland in spite of indispensable necessity for livestock production in Korea. The importance of pastoral system in hill region and woodland is particularly emphasized in a standpoint of sustainable livestock production. Main chapter comprises the principle and techniques applicable for improving the utilization of hill pasture and woodland. We finally discussed the problems to solve and future works for a successful livestock production in hill and mountainous area in Korea.

  • For last 150 years, blackbirds have moved from their ancestral habitat, the woodland edge, to man-made habitats such as farmland, parks and gardens. These alternative habitats have become one of main blackbird habitats. I compared density of nests and blackbirds in parks, woodland and campus of University of East Anglia to investigate habitat preference. Blackbirds preferred the area covered by $10\sim50%$ of tree or bush patches for their foraging and nesting sites. Blackbirds were more frequently found near buildings rather than far from buildings. Nest characteristics did not affect predation rate and nest preference. This study suggests that man-made habitats may be important for avoiding predation.

  • In Ethiopia, dry land vegetation including the fairly intact lowland and western escarpment woodlands occupy the largest vegetation resource of the country. These forests play a central role in environmental regulation and socio-economic assets, yet they received less scientific attention than the moist forests. This study evaluated the woody plant species composition, population structure and carbon sequestration potential of the A. senegal woodland across three distance gradients from the settlements. A total of 45 sample quadrants were laid along a systematically established nine parallel transect lines to collect vegetation and soil data across distance gradients from settlement. Mature tree dry biomass with DBH>2.5 cm was estimated using allometric equations. A total of 41 woody plant species that belong to 20 families were recorded and A. senegal was the dominant species with 56.4 IVI value. Woody plant species diversity, density and richness were significantly higher in the distant plots compared to the nearest plots to settlement (p<0.05). The cumulative DBH class distribution of all individuals had showed an interrupted inverted J-shape population pattern. There were 19 species without seedlings, 15 species without saplings and 14 species without both seedlings and saplings. A significant above ground carbon (5.3 to 12.7 ton ha-1), root carbon (1.6 to 3.6 ton ha-1), soil organic carbon (35.6 to 44.5 ton ha-1), total carbon stock (42.5 to 60.7 ton ha-1) and total carbon dioxide equivalent (157.7 to 222.8 ton ha-1) was observed consistently with an increasing of distance from settlement (p<0.05). Distance from settlement had significant and positive correlation with species diversity and carbon stock at 0.64⁎⁎ and 0.78⁎⁎. Disturbance intensity may directly influence the variation of species composition, richness and density along the A. senegal woodland. The sustainability of the A. senegal woodland needs urgent protection, conservation and restoration.
