Plant species distribution was studied on five reclaimed lands and one intertidal flat (control) on the western coast of Korea. Nineteen soil properties were analyzed. Of these, soil moisture, electrical conductivity, and levels of Na and Cl had the greatest effect on plant distribution. The plant species were divided into four groups, according to the amount of soil moisture found at their habitats. Triglochin maritimum and Typha angustata were found on the wettest sites; Phragmites communis, Carex scabrifolia, Suaeda japonica, Zoysia sinica, and Salicomia herbacea in places with relatively high moisture; Aster tripolium and Phacelurus latifolius in areas with medium levels of moisture; and Atriplex subcordata, Chenopodium virgatum, and Trifolium repens in the driest areas. The species also were divided into four groups, according to the degree of soil electrical conductivity: Highest, S. herbacea, Limonium tetragonum, Suaeda asparagoides, and S. japonica; Relatively high, A. tripolium, C. scabrifolia, P. communis, Artemisia scoparia, and Z. sinica; Relatively low, Setaria viridis, C. virgatum, Sonchus brachyotus, A. subcordata, Calamagrostis epigeios, and T. angustata; and Lowest, Imperata cylindrica var. koenigii, Aeschynomene indica, Lotus corniculatus var. japonicus, and T. repens. On reclaimed land, plant species were found in zones, according to the degree of desalinization (i.e., levels of Na and CI).
