This study was carried out to identify environmental factor to influence fruiting of Vicia chosenensis populations distributed in Hongcheon-gun region, Korea. The populations was dominated by Quercus mongolica in the tree layer, and Lindera obtusiloba and Lespedeza maximowiczii in the shrub layer. Syneilesis palmata(21%) was abundant around reproductive state points and vegetative state points, and Artemisia stolonifera(13~18%) and Spodiopogon sibiricus(10~11%) show second high frequency in the both points. It was found that the soil moisture content in the Vicia chosenensis population was 20.4~21.9%; 8.6~14.9% for organic matter; 0.3~0.5% for the total N;12.7~16.9 ppm for available phosphorus; 22.5~28.5 $cmol_ckg^{-1}$ for CEC; 5.3~5.5 for soil pH, respectively. The microhabitat of individuals was restricted to areas high in understory light. Especially, reproductive individuals were more likely to be located than vegetative individuals in canopy gaps. Therefore, our results suggest that a proper forest management maintaining canopy gaps is needed for keeping natural Vicia chosenensis population.
