This study was conducted to provide the basic information for effective conservation and management of coastal forest by analysis the vascular plant in Daewangam park. The vascular plant in Daewangam park was 204 taxa, 73 families, 156 genera, 183 species, 2 subspecies, 4 forma, and 15 varieta. Among them, seashore plants accounted for 6.4% of total plants and they were 13 taxa such as Andropogon ischaemum and Tetragonia tetragonoides, and the Pteridophyte index (Pte-Q) was 0.49. The plants of Compositae, Rosaceae, Graminea, Leguminosae, and Liliaceae showed high distribution. Korean endemic species were 3 taxa such Campanula takesimana, Aster koraiensis and Forsythia koreana. Three rare species of Campanula takesimana, Magnolia kobus and Glehnia littoralis listed as rare plants by the Korea National Arboretum were found in Daewangam park. Naturalized plants were identified 18 taxa including Cerastium glomeratum, Bidens frondosa, and so on, and Naturalization index was 8.8%. The specific species of I～V grades by phytogeography were 28 taxa including Campanula takesimana, Magnolia kobus, Rubus ribisoideus, and so on.

The high surface area polymer, AquaMatsⓇ was used for the leachate purification process originated from the Samsan Dong Landfill in Ulsan Metropolitan City. And then, three species of dominant microbes were isolated and identified from AquaMatsⓇ. Gram staining revealed these microbes to be Gram-negative rod strains: They were identified as Agrobacterium radiobacter, Pseudomonas cepacia, Flavobacterium indologenes. All they showed no growth on media in which the leachate was added alone, but a rapid proliferation rate on media with yeast extract as nutrient requirements.
