The vascular plants in the Ohseosan and the Bongsusan, Chungnam were listed 439 taxa (9.0% of all 4,881 taxa of vascular plants); 95 families, 268 genera, 339 species, 5 subspecies, 75 varieties and 20 forms. Furthermore, the Ohseosan were listed 339 taxa and the Bongsusan were listed 306 taxa. So, Hemicryptophytes (H) were 107 taxa (24.4%), Therophytes (Th), Geophytes (G) same as were 82 taxa (18.7%) showed high proportional ratio in life form. Based on the list of rare plants, 4 taxa; Aristolochia contorta, Viola albida, Scutellaria insignis (LC) and Scrophularia koraiensis (DD) and endemic plants, 8 taxa; Aconitum pseudolaeve, Ajuga spectabilis, etc. Based on the list of specific plants, 35 taxa; Wisteria floribunda for. floribunda in class IV, 5 taxa (Scutellaria insignis, Scrophularia koraiensis, etc.) in class III, 5 taxa (Acer triflorum, Cymopterus melanotilingia, etc.) in class II, 24 taxa (Pyrus ussuriensis var. ussuriensis, Campanula punctata, etc.) in class I. Based on the list of naturalized plants, 9 families, 20 genera, 24 taxa (Persicaria orientalis, Carduus crispus, etc.) and ecosystem disturbing plants were Rumex acetocella, Ambrosia artemisiifolia. Naturalization rate was 5.5% of all 439 taxa of vascular plants and urbanization index was 7.5% of all 321 taxa of naturalized plants. In particular, for rare plants, in and ex-situ conservation of genetic resources must surely be done, by preserving present natural habitats, discovering additional natural habitats and securing seeds. Moreover, ecosystem disturbing plants require long-term monitoring and consistent management, since not only do they disturb the ecosystem in competition with Korean native species, but damage humans, too.

From the enlisted the flora surveyed, the naturalized plants were 17 taxa in Jangsoo-ri windbreak forest and 19 taxa in Pyeongsa-ri windbreak forests with the Naturalization rate was 8.7 percent and 12.6 percent, respectively. In Jangsoo-ri windbreak forest, there has been occurred many man-made impair and development without legal institution and control. So, it needs in haste institutional conservation measures and systemic database construction about function and necessity of windbreak forest. In Pyeongsa-ri windbreak forest, recently many people visited here. So, if we make eco-tour place connecting nearby coast and windbreak forest, it will contribute resident's economic profit and opportunity, concerns about windbreak forest, and necessity of conservation measures. Recently, the windbreak forests in Jangsoo-ri and Pyeongsa-ri should be bereaved windbreak forest of function by the human activities.
