This study was carried out to investigate the distribution and habitat characteristics of Boehmeria for utilization and conservation plan of natural agro-plant resources in South Korea. The native habitat of B. longispica Steud., B. platanifolia Fr. et Sav., B. spicata Thunb., and B. tricuspis var. unicuspis Mak. were distributed nearly all areas in South Korea. B. nivea Gaudich. was distributed south of Chungnam but B. pannosa Nak. et Sat. and B. sieboldiana Bl. were partially distributed toward the southern part in South Korea. The average number of plant species growing with Boehmeria in natural habitat was found 124.9 species and Artemisia princeps var. orientalis Hara showed the highest importance value among neighbor species. B. platanifolia Fr. et Sav. and B. spicata Thunb. were the most commonly neighbor species growing with Boehmeria in rate of 49%. Average yearly precipitation and temperature of habitat for Boehmeria were 1100 mm to 1390 mm and 11.3^{circ}C;to;13.7^{circ}C respectively. Soil characteristics of habitat for Boehmeria. were that pH was 5.3 to 7.2 and B. nivea Gaudich. was higher content of organic matter than the other Boehmeria. Content of K and Na were similar among Boehmeria. P_2O_5, Ca and Mg were shown a little difference among seven species.
