The purpose of this study was to examine the species of 117 wooden elements which were used in the Daewungjeon Hall (National Treasure No. 805, constructed in A. D. 1659) of Bukjijangsa Temple, Daegu, Korea. Pillars were identified as 5 red pines (hard pines; most likely, Pinus densiflora S. et Z.), 2 Cerris section of subgenus Lepidobalanus (deciduous oaks) and 3 Tsuga spp. Hwalju columns were 3 Abies spp. and 1 red pine. Head-penetrating ties were 8 red pines and 1 Cerris sp.; Pyeongbang, 3 red pines and 6 Cerris spp. Purlins were identified as 17 red pines, 16 Cerris spp. and 1 Tsuga sp. Angle rafters were 3 red pines and 1 Cerris sp., and end angle rafters, 2 red pines, 1 Zelkova serrata and 1 exotic hard pine. All of brackets (31 woods), jangyeo (4) and deot-chunyeo (2) were identified as red pines. As a whole, red pines (70.1%) and Cerris (22.2%) were major species used in the Daewungjeon Hall of Bukjijangsa Temple.

This study was carried ou to compare sprouting and sprout growth after the stumps of four Quercus species(Q. mongolica, Q. variabilis, Q. acutissima and Q. dentata) were cut at 20cm from the soil surface in 1996 and 2000 at Mt. Taehwa, Kwangju-Gun, Kyounggi-Do, Korea. The results obtained were as follows: ⑴ Q. mongolica showed most vigorous sprouting, followed by Q. variabilis, Q. dentata, and Q. acutissima. ⑵ The sprouting ability was more vigorous when cut in winter to earl spring than that in summer. ⑶ The initial diameter growth of the sprouts for 2 year after cutting was the highest in Q. acutissima, followed by Q. dentata, Q. mongolica and Q.variabilis, but the growth for 5years after cutting was Q. variabilis > Q. mongolica > Q. dentata > Q. acutissima. ⑷ The height growth of sprouts for 2 years after cutting was the highest in Q. acutissima and followed by Q. mongolica, Q. dentata and Q. variabilis, but the growth for 5 years after cutting was Q. variabilis > Q. mongolica > Q. dentata > Q. acutissima. ⑸ Tending is needed for the stands of Q. variabilis and Q. acutissima to be regenerated successully by sprouting. ⑹ The sprouting ability of Quercus species decreased with incerasing stump diameter, while its diameter growth seemed to increase.

This study was conducted to compare the physical and chemical properties of soils in Quercus acutissima, Q. mongolica, Q. serrata, and Q. variabilis stands. A total of 423 plots (Q. acutissima 72 plots, Q. mongolica 150 plots, Q. serrata 97 plots, and Q. variabilis: 104 plots) were examined to determine the soil properties of A and B horizons throughout the country. The physical and chemical properties of soils were significantly different among the four different Quercus spp. stands. The sand content in both horizons was significantly higher in Q. acutissima stands than in the other three oak stands, whereas the clay content was lowest among the four stands. The soils in Q. mongolica and Q. serrata stands were more acidified than those in Q. acutissima and Q. variabilis stands. The concentrations of organic carbon and total nitrogen in both soil depths were significantly higher in Q. mongolica stands than in Q. serrata, Q. variabilis, and Q. acutissima stands. The content of available phosphorus was significantly higher in Q. mongolica and Q. serrata stands than in Q. acutissima and Q. variabilis stands; whereas the contents of exchangeable potassium, calcium, and magnesium were lower in Q. mongolica and Q. serrata stands than in Q. acutissima and Q. variabilis stands. The cation exchange capacity was highest in Q. mongolica stands, followed by that in Q. serrata, Q. variabilis, and Q. acutissima stands. These data indicate the need to design a nutrient management plan to enhance the low soil pH and exchangeable cation in Q. mongolica and Q. serrata stands.

Archaeological investigations carried out in the Chilgok Housing Land Development Area have identified large-scale settlements from the Bronze Age and Three Kingdoms periods. The settlement site in Dongcheon-dong, Daegu was found to include sites of pit dwellings, buildings with elevated floors, stone coffin tombs, wells, catchment basins, stone mounds, furrows, cropland, moats, and river channels. These findings offer insight into diverse aspects of settlements during the Bronze Age. This study analyzed the species of trees that produced the materials for eight wooden artifacts excavated from a Bronze-Age river channel site. The analysis identified two examples of Pinus spp., two examples of Abies spp., and four examples of Quercus sp. The three artifacts of undetermined use were made using wood from Pinus spp. and Abies spp. Among the five artifacts identified as building components, one was made from Pinus spp. and four were made from Quercus sp.

Species of 741 charcoal samples, which were excavated from the dwelling sites of the bronze age $(about\;2500\~3100\;B.P)$ at Hyeonwha-ri, Pyungteak, Korea, were identified. Most of samples were deciduous oaks (Quercus spp.; $97.7\%$) and others were alders (Ainus spp.; $1.9\%$) and soft pines (Pinus spp.; $0.4\%$). Tree rings of nine largest samples were also examined. The numbers of annual rings were 8 to 36 and mean ring width was rather narrow $(0.65\~1.82\;mm)$. Most samples possessed pith and tylosis. The results indicate that logs 10 to IS cm diameter had been used for the poles of houses without further processing.

This study was conducted to identify wood species of 72 wooden parts (pillar, beam, jangyeo, purlin, judu, soro, bracket, deagong, ceiling panel, etc.) used for Daewungjeon Hall in the Woonsoosa Temple, Busan in Korea. Identified wood species were 67 Pinus spp. (Kesiya group), 4 Carpinus spp. and 1 Quercus spp. (Cerris group). In pillars, 14 red pines and 4 Carpinus and in purlins, 4 red pines and 1 Cerris were found. Other elements were red pines. Carpinus woods, which were used for the lower portions of three pillars (Dongbari), seemed repaired parts. A carved wood used for the stand of Buddhist statues was identified as Alnus spp. This study showed that Daewungjeon Hall of the Woonsoosa Temple was made mostly of red pines.

The purpose of this study is to examine the species of wooden members used in the Youngsanjeon Hall of the Sucknamsa temple in Anseong, Korea. Ninety-five wood samples from pillars, head-penetrating ties, beams, corner rafter, rafter, floor board and other wood members were identified. Seven species identified were hard pine, exotic pine, Zelkova serrata, Ginkgo biloba, Diospyros, Quercus(Cerrus) and Pyrus spp. In the case of pillars, eight were hard pines and the others Zelkova and Pyrus. Species of angle rafter were Ginkgo biloba and Zelkova. and those of beams were one hard pine and one Zelkova. Two purlin samples were Quercus(Cerrus) and rafters were hard pines except one Ginkgo and one exotic pine. Roof-filling timbers were identified as Zelkova and Diospyros spp. The other samples of roof-filling timbers were all identified as hard pines. The use of Ginkgo and several hardwoods in addition to hard pines may indicate supply of local logs near the Sucknamsa temple.

Totally 588 specimens, which were excavated from well sites(I or II site) of near the new Kyungju National Museum building, were identified 32 species. Diospyros spp. and Fraxinus spp. were the most common and occupied 14.8%(I-site) or 20.9%(II-site), 14.1%(I-site) or 12.8%(II-site) of the total specimen number respectively. And then other common species were follows ; Pinus densiflora, Quercus spp., Castanea crenata, Prunus spp., Pourthiaea spp.. Because the I-site were adjacent to the II-site, the 13 out of 25(I-site) or 20(II-site) identified species were common. Most of identified species had fruits, beautiful crowns and good qualities of lumber.

The study investigated the forest vegetation structure of Kongju National University Forests in the vicinity of Seokjangri-dong to provide the information needed for efficient use and management. It conducted a Z-M phytosociological vegetation survey in 60 quadrate plots in August 2019 and generated the actual vegetation map by analyzing the physiognomic community classification and mean importance value. The physiognomic community classification showed five vegetation community types: Quercus acutissima community, Pinus densiflora community, Quercus variabilis community, Pinus rigida community, and Quercus serrata community. The relative importance value in the Q. acutissima community was 31.4% for Q. acutissima, 9.6% for Prunus spp., and 9.0% for Q. variabilis. In the P. densiflora community, it was 24.9% for P. densiflora, 12.4% for Q. acutissima, and 11.5% for Q. serrata. In the Q. variabilis community, it was 25.3% for Q. variabilis, 9.8% for Prunus spp., and 8.5% for Q. acutissima. In the P. rigida community, it was 28.4% for P. rigida 28.4%, 10.0% for Q. acutissima, and 9.3% for P. densiflora. In the Q. serrata community, it was 27.0% for Q. serrata, 11.3% for Q. aliena, and 11.5% for Styrax japonica. The actual vegetation map based on the uppermost dominant species to identify the forest vegetation's spatial distribution characteristics indicated that the natural vegetation covered the most with 87.5%, the number of vegetation patches was 87, and the average area per patch was 1.46ha.
