Juniperus chinensis var. sargentii Henry is a short and creeping evergreen shrub which reaches about 50 cm in height and occurs in the northeast Asia and in high mountains over the South Korea. Its distribution is restricted, and the number of individuals are gradually decreasing. This study was conducted to estimate spatial pattern, genetic diversity and spatial genetic structure of J. chinensis var. sargentii. A total of 131 clumps were studied in the study area (40 m × 60 m). The spatial pattern of this population was random (Aggregation index R=1.031). In spite of the small number and the limited distribution, the level of genetic diversity (Shannon's index I=0.463) was relatively high as compared with those of other plant species with similar ecological characteristics.
