Abstract
This study was conducted to provide basic information for conservation and restoration through investigation of vegetation structure on the Euchresta japonica Hook. f. ex Regel (Korean endangered species) in Mt. Halla in Jeju Island. Very few individuals were discontinuously distributed and restricted at 220 m above sea level, very steep slope ($40-50^{\circ}$), rocky area of north face of Donneko Valley. For investigation of environmental condition, we established $10{\times}20\;m$ quadrat and one control $20{\times}20\;m$ quadrat in the habitats. Thirty three species were found at habitat under 10-16 m Castanopsis sieboldii tree layer (70-80%). The principal causes of threat which were investigated in this study are competition among companies, very steep slopes, artificial management of valley. For restoration and conservation of habitats, it is needed to suitable plans.
