We evaluated the distribution, standing crop, and quality of legumes growing naturally throughout Cheju Island in July 1997 to June 1998 to select potential forage legumes adapted to this region. There are 84 leguminous species in the island of which 52 species were native and 32 naturalized or cultivated. Sixty-four species were herbaceous while 20 woody. Fifty-three species were perennials, 20 annuals and 11 biennials. Of the 84 species, 20 species were herbaceous vines and 2 woody vines. Twelve, 61, 49, 24, 10, 4, and 1 species were distributed at below 50, 50 to 350, 350 to 1100, 1100 to 1400, 1400 to 1800, and 1800 to 1950 in altitude, respectively. Cassia mimosoides var. nomame, Lespedeza cuneata, Lespedeza maximowiczii, Pueraria thunvergiana, and Trifolium repens were distributed from sea shore to 1800 in altitude. Twelve, 20, 18, 17, 14, 2 and 1 species bloomed in April, May, June, July, August, September and October, respectively. High frequency species were Cassia mimosoides var. nomame, Dunbaria villosa, Glycine max, Kummerowia striata, Lotus corniculatus var. japonicus, Lespedeza cuneata, Lespedeza maximowiczii, and Pueraria thunbergiana while low were Canavalia lineata, Trifolium lupinaster var. alpinum, Astragalus adsurgens var. alpinus. Species which produced 3250 to 3585 kg10a of standing crop were Astragalus adsurgens, Astragalus membranaceus var. alpinus, Conavalia lineata, Lespedeza cuneata, Lespedeza maximawiczii, Pueraria thunbergiana, Vicia pseudo-orobus. Species with over 17% crude protein content were Desmodium oldhami, Kummerowia striata, Vicia amoena, Vicia angustifolia var. minor, Vicia nipponica, Vicia pseudo-orobus, Vicia angustifolia var. segetillts, and Vicia tetrasperma Species which produced higher standing crop with over 15% crude protein content were Astragalus adsurgens, Astragalus adsurgens var. alpinus, Astraglus membranaceus var. alpinus, Conoxilia lineata, Cassia mimosoides var. nomame and Vicia pseudo-orobus.
