Phytosociological characteristics on Quercus acutissima forests distribution in Daechong-dam basin survey has been carried out using Z.-M. School's methodology and numerical-classification analyses. A total of 43 phytosociological relevés were sampled. Syntaxa were described as Oplismenus undulatifolius-Quercus acutissima community(typicum subcommunity, Phryma leptostachya var. asiatica subcommunity, Ulmus davidiana var. japonica subcommunity), Quercus acutissima community and Quercus variabilis-Quercus acutissima community (typicum subcommunity, Castanea crenata subcommunity). The above three plant communities were classified with species composition reflecting local environmental characteristics of mountain topographies, inclination degrees, and rock exposure rates. Conclusively, those communities were recognized as secondary vegetation affected by high intensity and frequency of human impacts as they inhabited in southward hill lands and low lying grounds in mountains adjacent to human settlements and arable lands. Quercus acutissima community was classified as rural type syntax based on their inlandward distribution and species composition differences from urban forests. Afforest process and natural succession were discussed in relation with habitat environmental elements of Quercus acutissima forest in the survey area.

Background: The sprouts of oak species play an important role in maintaining the oak community in a disturbed environment. In this study, we cut 1-year-old oak in three times during the 3 years and measured the sprout responses to know sprouting ability of six deciduous oaks in Korea. Results: Oak sprouts have appeared in spring and fall, and some of the sprouts had lifespan as short as a month. As the number of cutting increases, sprout number of Quercus acutissima increased whereas the other oak species decreased or died. The average number of sprouts over the 3 years was from 1.4 (Quercus mongolica) to 2.2 (Q. acutissima) per individual. Quercus serrata died after the second cutting, and Quercus dentata died after the third cutting. So, the two species have the lowest sprouting ability among six oak species. The sprouts grew actively during fall and slowly in summer. The sprout length during the 3 years was in the following descending order: Q. acutissima, Quercus aliena, Q. dentata, and Q. mongolica. Sprout of Q. acutissima and Q. aliena generated steadily over the 3 years, and sprout of Quercus variabilis and Q. mongolica was changed by year. After the 3 years, the number of sprouts increased only in Q. acutissima but sprout number of the other five oak species decreased. The sprout length of Q. acutissima, Q. aliena, and Q. variabilis increased, but sprout length of the other three oak species decreased. The average survival rate of saplings over the 3 years was in the following descending order: Q. acutissima, Q. aliena, Q. variabilis, and Q. mongolica. Conclusions: As a result, the sprouting ability of Q. acutissima was the highest. Such level of sprouting ability may be the evidence of how Q. acutissima community exists as a dominant species in a disturbed environment in lowlands of Korea peninsula.

Field classes are necessary to grow the ability of and an attitude toward exploring nature and to shape the basic concept of natural science. I tried to develop a site for field classes and the old road Naori's hill is an ideal place with convenient traffic and established youth camps. As a result the vegetation was divided into five associations and communities. The vegetation units obtained in the present study were as follow: Quercus acutissima community, Pinus densiflora community, Pinus densiflora-Quercus acutissima community, Quercus acutissima-Pinus densiflora community, and Quercus mongolica community. In all survey areas 100 family 336 genus 587 species of palants was found. Furthermore, it provides lots of plants throughout the seasons. Not only the flora but also flowering phenology, variety of floral color and growth habits can be used as teaching items. Incorporation of diverse knowledge of plants at the old road Naori's hill into biology teaching will give students academic stimuli and teachers an opportunity of retraining. With a combination of use of visual instruments, the purpose of conceptual and exploring biology is more easily achieved.

The purpose of the study is to analyse and classify the characteristics of Gongsanseong forest through phytosociological and quadrat method with 20 plot samples. In result, the forest was classified as Quercus acutissima community. The subcommunity was composed of Quercus aliena and Zelkova serrata. The average vegetation coverage of Quercus aliena subcommunity was upper tree layer (83%), lower tree layer (48%), shrub layer (39%), and herb layer (30%), while the average vegetation coverage of Zelkova serrata subcommunity was upper tree layer (76%), lower tree layer (52%), shrub layer (40%), and herb layer (45%). The order of importance value of the forest community with DBH 2cm above plants was Quercus acutissima (72.62), Quercus aliena (40.52), Prunus sargentii (19.81), Styrax japonica (19.39), Zelkova serrata (15.78), Robonia pseudoacacia (14.76), Quercus variabilis (13.83), Sorbus alnifolia (13.71), Platycarya strobilacea (10.74), Pinus densiflora (10.08), and Quercus serrata (9.31). According to breast diameter analysis results, it is expected that the importance value of Prunus sargentii and Zelkova serrata will be continuously increased while Quercus sp. is dominating the forest. With the result of ordination analysis, the relationship between the forest community and environmental factors could be affected by soil nutrition, moisture, and elevation etc.
