The present study was performed to examine the community structure of benthic macroinvertebrates in the provincial park of Mt. Daedun and its nearby region. Sampling was conducted two times in May.June and October.November, 2000. Main two areas are Mt. Anpyong (470.0m) and Mt. Daedun (877.0m) area. Total taxa of benthic macroinvertebrates were 111 species, 47 families, 15 orders, 6 classes in 4 phyla. Aquatic insects were composed of 29 species in ephemeroptera, 10 species in odonata, 7 species in plecoptera, 2 species in hemiptera, 2 species in megaloptera, 23 species trichuptera, 6 species in coleoptera and 17 species in diptera. Other non-insects were composed of 1 species in platyhelminthes, 8 species in gastropoda, 2 species in oligochaeta, 3 species in hirudinea and 1 species in crustacea. Ephemeroptera, trichoptera and plecoptera as indicators in clean water were very abundantly. Occurrence species at each surrey area was 77 species at Mt. Anpyong area and 89 species at Mt. Daedun area, respectively. Mean values of species diversity indices were 3.04 and 2.69, respectively. According to the saprobic system based on the species diversity indices of benthic macroinvertebrates, Mt. Anpyong region are determined as polysaprobic area or ${\beta}-mesosaprobic$ area and Mt. Daedun region are determined as polysaprobic area, $\beta-mesosaprobic$ area or ${\alpha}-mesosaprobic$ area.

Through the research of tracheophytes type around Mt. Daedun, we are aiming at figuring out the habitat condition of useful resource plants by the classification of vegetation units and communities using the Z-M phyto-sociological method in the basis of the traits of species composition and by the analysis of vegetation and environment by way of coincidence method. Tracheophytes in our research sites was classifid into 117 family, 475 genus 797, species 102 variety,18 breed, in total to 917 kinds. The forest around Mt. Daedun district was classified into 6 communities, 12 groups, 2 sub-groups according to feature species group, differential species group and differential. Judging the result from the examination of community classification factors by the coincidence method, vegetation unit was decided by altitude and topography.

Several yeast strains were isolated from leaves collected from Mt. Daedun and Mt. Chilgap in Korea. A total of 79 strains of 32 species were isolated from 44 leaves obtained from Mt. Daedun. Cryptococcus spp., including Cryptococcus magnus, were found to be dominant, while 16 strains of Aureobasidium pullulans were isolated. Among the strains isolated from Mt. Daedun, Asterotremella humicola JSL502, Barnettozyma californica JSL503, Bullera unica JSL501, Bulleromyces albus JSL505, and Candida vaccinii JSL507 are considered rare yeast species in Korea. All of these rare strains, except for Bulleromyces albus JSL505, formed ascospores. Bullera unica JSL501 was able to grow in yeast extract-peptone-dextrose (YPD) medium containing 10% NaCl. Twenty-five yeast strains of 18 species were isolated from 43 leaves obtained from Mt. Chilgap. Six strains of Pseudozyma spp., including three strains of Pseudozyma aphidis, were isolated in the dormant state. Of these strains, the occurrence of Rhodotorula phylloplana JSL515, Rhodotorula pinicola JSL516, Schwanniomyces vanrijiae JSL517, and Sporisorium loudetiae JSL518 is rare in Korea. Only Sporisorium loudetiae JSL518 formed ascospores, while Rhodotorula pinicola JSL516 and Sporisorium loudetiae JSL518 formed pseudomycelia. The halophilic yeast Schwanniomyces vanrijiae JSL517 was isolated and observed to grow in YPD medium containing 5% NaCl.

Many fungi were collected at Mt. Daedun Provincial Park between the periods from March 2001 to October 2002 and they were identified. According to the results, the fungi diversity included 2 division, 3 subdivisions, 5 classes, 4 subclasses, 12 orders, 35 families, 75 genera and 153 species. Among them Ileodictyon is unrecorded genus and Ileodictyon gracile, Mycena flosum-nivium and Tricholoma lascivum are newly to Korea. Dominant family are Tricholomataceae, Russulaceae and Polyporaceae;genus Amanita and species Collybia confluens and Russula emetica In useful fungi and ecological resources, edible fungi included 51 species; culture fungi 10; poisonous fungi 18: medicinal fungi 17: anticancer fungi 22: ectomycorrhizal fungi 26 and wood rotting fungi 51, In geographical distributions of Chonbuk areas, same species are 50 spcies of Jeongup ; 56 of Mt.Manduck : 84 of Mt.Jiri : 28 of Pyonsan national park : 59 of Cheonju arboretum and 51 of Mt,Sunun.

Floristic composition and vertical distribution of Mt. Daedun (western slope) were investigated from 1985 to 1986. The results are as follows; 108 families, 346 genera, 511 species, 2 subspecies, 75 varieties, 5 forma or 593 taxa including 77 cultivars. The floral data showed the ecological characteristics such as the value 346 in Fisher's Index, H-D1-H5 in biological type, 10.9% in urban index of naturalized plants and 60.5% in erect form growth form. Based on the physiognomy and population density of dominant tree species the forest vegetation of Mt. Daedun (western slope) was classified into 5 types; Quercus mongolica forest and Q. variabilis forest at 800m above, Carpinys laxiflora forest and Acer mono forest at 700m to 800m and Sapium japonicum forest at 500m to 800m in altitude. And Lindera erythrocarpa forest and zelkova serrata forest are widely distributed at 400m to 800m in altityde along valley and at mountain foot area.

This study was carried out to characterize pinus densiflora forests in middle province (Mt. Seolag, Mt. Taebaik) south province (Mt. Sokli, Mt. Jiri) and south-coast province (Mt. Daedun) of Korea. The appearance species in the P. densiflora alliance included 325 taxa and varied according to the direction of slopes. The steeper the slope was, the fewer number of taxa were observed. The floristic composition of south-coast province was gradually changing to the south hemispheric factors. Dominant species groups of P. densiflora alliance were classified into P. densiflora, Quercus serrata ( layer), Rhus trichocarpa ( layer), Lespedeza maximowiczii var. tomentella (S layer), Artemisia keiskeana, Carex humilis var. nana, Spodiopogon sibiricus (K layer). Quercus variabilis, Fraxinus sieboldiana and Styrax japonica association were formed under the P. densiflora alliance. Quercus, Rhus, Lespedeza and Rhododendron groups maintained high ecological relationships one another. The soil factors (pH, organic matters, and water field capacity)and relative light intensity tended to show negative correlation, which were significantly different among provinces. The P. densiflora forests of Korea were classified into one alliance and four associations, that is, pinion densiflorae Suz.-Tok. 1966, Quercetum variabilae ass. nov., Quercetum mongolicae ass. nov. Fraxinetum sieboldianae ass. nov. and Styraxetum japonicae ass. nov.

The purpose of this study was to investigate the distribution of vascular plants growing at the Mt. Daedun provincial park area in the boundary between Nonsan-si, Geumsan-gun, Chungcheongnam-do and Wanju-gun, Jeollabuk-do, Korea. We collected the vascular plants 9 times from May 2016 to July 2017. The flora of Mt. Daedun was classified as a total of 434 taxa comprising of 95 families, 278 genera, 388 species, 3 subspecies, 38 varieties and 5 forma. Among them, the endemic plants in Korea that the investigation found were 11 taxa including Broussonetia kazinoki Siebold, Clematis trichotoma Nakai, Thalictrum actaefolium var. brevistylum Nakai, etc. It also found rare plant species, as designated by the Korea Forest Service were 6 taxa including 5 grade LC taxa such as Eranthis stellata Maxim., Viola albida Palib., and Scopolia japonica Maxim. and 1 grade DD taxa, Scrophularia koraiensis Nakai. The special floristic plants were a total of 35 taxa such as 9 taxa in degree III (Eranthis stellata Maxim., Stewartia pseudocamellia Maxim., Acer palmatum Thunb., etc.), 7 taxa in degree II (Equisetum hyemale L., Potentilla dickinsii Franch.&Sav., Viola orientalis (Maxim.) W. Becker, etc.) and 19 taxa in degree I (Dryopteris crassirhizoma Nakai, Cephalotaxus koreana Nakai, Ulmus parvifolia Jacq., etc.) to provide basic data. No taxa in grade V or IV were found. The naturalized plants were 34 taxa including Rumex acetosella L., Phytolacca americana L. and Chenopodium album L., and the percentage of urbanization index was 10.6% while the naturalized plant index was 7.7%.
