This study evaluated the general nutritional ingredients such as crude fats, crude ashes, crude proteins, total polyphenols, and total flavonoids in 18 kinds of edible tree sprouts. The tree sprouts of Philadelphus schrenckii, Lycium chinense, and Morus alba had the highest crude fat, crude ash, and crude protein content, respectively. The tree sprouts of Cedrela sinensis (CSS) with high ABTS⁺ radical scavenging activities had a high content of total polyphenols (175.65 mg/g ext.) and total flavonoids (75.18 mg/g ext.). The simultaneous determination of flavonoids such as rutin, isoquercitrin, quercitrin, afzelin, and quercetin in CSS was conducted using high-performance liquid chromatography with a wavelength of 270 nm. Among the flavonoids, the content of quercitrin in CSS was the highest at 59.28 mg/g ext. This study also aids the quality control of many edible tree sprouts by analyzing the general components, total polyphenols, and total flavonoids.

To investigate the structure and the conservation strategy of natural forest at Sangwonsa, Pirobong, Horyongbong area in Odaesan, 23 plots(20*20m) were set up with random sampling method. Three groups were classified by cluster analysis; Quercus mongolica-Abies holophylla community, Acer mandshuricum- Abies nephrolepis community, and A. holophylla-Ulmus laciniata community. High positive correlations were proved betwween Tilia amurensis and Acer mono; Sorbus commixta and Euonymus macropterus, Betula ermanii, and Viburnum sargentii; E. macropterus and V. sargentii; B. ermanii and V. sargentii; A. mephrolepis and Syringa velutina var. kamibayashii; S. velutina var. kamibayashii and Salix hulteni; Pinus densiflora and A. holophylla. High negative correlations were proved between Q. mongolica and Juglans mandhuricum; Sasa vorealis and E. macropterus; Acer mono and Philadelphus schenckii; A. holophylla and E. macropterus, B. ermanii, S. velutina var. kamibayashii, and Salix hulteni.

Korean endemic plants of this area were 12 taxa; Asarum misandrum, Clematis brachyura, Philadelphus schrenkii, Forsythia koreana, Polygonatum infundiflorum, etc. The red list of vascular plants according to IUCN valuation basis were examined, endangered species (EN) Abies koreana, Near Threatened species (NT) both Wikstroemia trichotoma and Sparganium erectum, Least Concern species (LC) Platycladus orientalis, Swertia diluta var. tosaensis and Iris minutoaurea and by Not Evaluate species (NE) Polygonatum infundiflorum. The floristic regional indicator plants found in this area were 45 taxa comprising two taxa of grade V and VI, nine taxa of grade III, three taxa of grade II, 29 taxa of gradeI. The naturalized plants were identified as 64 taxa and the percent of naturalized index (NI) was 10.7% of total 595 taxa vascular plants. Ecosystem disturbance wild plants were consisted of eight taxa; Rumex acetosella, Sicyos angulatus, Solanum carolinense, Ambrosia artemisiifolia, Ambrosia trifida, Aster pilosus, Hypochaeris radicata and Lactuca scariola. Furthermore, therophytes (26.5%), hemicryptophytes (26.0%), Geophyte (14.0%) showed high proportional ratio in life form spectrum.
