The forest vegetation of Mt. Seongju area, near Boryeong, was surveyed from August to October 2013. The vegetation of Mt. Seongju area classified into 13 main plant communities according to the dominant species: Pinus rigida community, Alnus hirsuta community, P. densiflora plantation, Larix leptolepis community, Chamaecyparis obtusa community, Pinus koraiensis community, Quercus variabilis community, Q. variabilis-P. densiflora community, Q. acutissima community, Q. mongolica community, P. densiflora community, P. densiflora - Q. variabilis community, and Carpinus laxiflora community. In addition, the Q. variabilis commintity is distributed on southern slope and Q. mongolica community on the northern slope. Carpinus laxiflora community distributed on the southern slope and ridge of the Mt. Seongju. Another specific communty was P. densiflora plantation, which was artificially planted as the purpose of a restoration after mining several years ago. Q. variabilis community showed higher diversity index than other communities. DGN 7 grade appeared 90.3% of Mt. Seongju area. The frequency distribution in DBH-class of dominant tree species for Q. mongolica community, P. densiflora community, and Carpinus laxiflora community showed stable community structure, but Quercus variabilis community showed intermediate stage of successional processes. The net primary productivity(NPP) was assumed as 1,588.22 g/m2/yr by Miami Model, and 1,488.39 g/m2/yr by Montreal model, respectively.
