  • We investigated the flora of Ibamsan Mt. and Baekamsan Mt., and discuss here important vascular plants found on these mountains. We created a plant list using voucher specimens collected from Ibamsan Mt. and Baekamsan deposited at CNU. There are 769 taxa in Ibamsan Mt. and Baekamsan Mt., consisting of 116 families, 403 genera, 687 species, 16 subspecies, 58 varieties, and 8 forms. Twenty-four endemic plants of Korea were found, including Coreanomecon hylomeconoides Nakai and Eranthis byunsanensis B. Y. Sun. There are 15 rare plants on Ibamsan Mt. and Baekamsan as designated by the Korea Forest Service, including Iris koreana Nakai and Chamaegastrodia shikokiana Makino & F. Maek., as well as 14 red-list plants as designated by the Ministry of the Environment, including Lycoris chinensis var. sinuolata K. Tae & S. C. Ko ex K. Tae & S. C. Ko and Cymbidium macrorhizon Lindl. In total, there are 133 taxa of floristic regional indicator plants, including four level V taxa, such as Iris koreana Nakai; ten level IV taxa, such as Lindera sericea (Siebold & Zucc.) Blume; 28 level III taxa, such as Botrychium japonicum (Prantl) Underw.; 22 level II taxa, including Hylomecon vernalis Maxim.; and 69 level I taxa, including Dryopteris erythrosora (D. C. Eaton) Kuntze. There are 37 invasive plants, including Rumex acetosella L. and Symphyotrichum pilosum (Willd.) G. L. Nesom.

  • Yeasts isolated from wild flowers of Gyejoksan in Daejeon city, Oseosan in Chungchungnamdo, and Baekamsan in Jeollabukdo, Korea were identified by comparison of nucleotide sequences for PCR-amplified D1/D2 region of 26S rDNA or internal transcribed spacer (ITS) 1 and 2 including 5.8S rDNA using BLAST. Twelve yeast strains of ten species and seventeen yeast strains of ten species were isolated from wild flowers of Gyejoksan and Oseosan, respectively. And thirty seven yeast strains of twenty four species were isolated from wild flowers of Baekamsan. Total thirty four yeast species were isolated from three different sample collection areas, but only nine species were overlapped from the at least two different sampling areas: Cryptococcus sp., Cryptococcus aureus, Cryptococcus flavescens, Cryptococcus flavus, Metschnikowia sp., Pseudozyma aphidis, Rhodotorula glutinis, Sporobolomyces carnicolor, and Sporobolomyces ruberrimus. Among them only Cryptococcus aureus was occurred from all three different collection sites. Other twenty five species were restricted to specific collection site suggesting that each area has distinctive yeast flora.

  • This study was done to classify the vegetation structure and ecological characteristics in Nakdong-jeongmaek. Therefore, we set up 34 plots($100m^2$) in 9km range. As a result of vegetation analysis, the vegetation of Seongsi valley was classified into the type of 6 communities i.e. Pinus densiflora community, Quercus variabilis community, Q. mongolica community, Q. serrata community, Betula schmidtii community, Larix leptolepis community. The average number of species and individuals were ranged from 8.5~10.5 and 27.5~75.6 respectively. Species diversity index(H') of groups were ranged from 0.6061~0.8736 per units, and it was highest and lowest in B. schmidtii and P. densiflora communities respectively. Similarity index of groups were slightly low. It was low in P. densiflora community, Q. mongolica community and L. leptolepis community, and lowest in Q. variabilis-Q. mongolica community.
