Stem and root of elm trees have used as traditional medical materials, but there is little information on the distribution and resources of habitats. Korean native growing Ulmus spp. (U. davidiana var. Japonica, U. parvifolia, U. davidiana, and U. macrocarpa) genetic resources studied through The National Forest Inventory of Korea data and field survey. The distributions of U. davidiana var. japonica according to elevation distributed evenly. Both U. parvifolia and U. davidiana were inhabited mostly at less than 200 m of altitude. Each Ulmaceae species widely were distributed nationwide, but a dominant species was different depending on locals. It observed that Ulmaceae inhabits mainly in steep slopes of 31-45 degrees. Most of the habitats regenerated by natural seeding and the most abundant species were a codominant tree. Distribution of trees in U davidiana var. japonica was 7 m-13 m, and in young U. parvifolia and U. macrocarpa, more than 25% of young trees less than 7 m observed. The distribution of the diameter of breast height of the U. davidiana var. japonica was 46.4% for 11-20 cm, 52.6% for 11-20 cm in U. parvifolia. The average T/R ratio was 0.83, and the mean weight ratio of root bark was 62%. As the results of this study, the domestic Ulmaceae biomassare very small. It is difficult to harvest in that the habitat on the slope. Thus, it is too hard to develop functional materials using biomass at present. Therefore, it is necessary to develop technology for the selection and propagation of elite trees of Ulmaceae.

In the present field study, the number of woody flora of Mt. Songni were summarized as 44 families, 89 generas, 140 species, 10 varities and 2 forms. Also, the flora among inland areas such as Mt. Paektu, Mt. Sorak, Mt. Songni, and Mt. Chiri, and insular areas, such as Oyoujong Island. Tokjok Archipelago, Kok-unsan Archipelago and Cheju Island, were compared, respectively, in order to interpret the characteristics of distribution patterns of the flora of this area. The flora of Mt. Songni were characterized as similar to the flora of Mt. Sorak, and also with that of Mt. Chiri. It was interpreted both the northern types of plants such as Aceraceae, Araliaceae, Fagaceae, Tiliaceae and Ulmaceae and the southern types of plants such as Celastraceae, Convolvulaceae, Euphorbiaceae, Rhamnaceae, Solanaceae, Crassulaceae and Urticaceae were fluxed considerably into this region.
