We carried out to examine the vegetation structure of a rare and endangered species, Milletia japonica.
The plots surveyed along the southern coast were fourteen, which is located in Namhaegum(3plot), Tongyourrgshi(7plot), and Geojaeshi(4plot). We collected several environmental factors, soil and vegetation characteristics against selected fourteen plots.
Milletia japonica was distributed to elevation of 20~90m, aspect of west, south-west, south, and south-east, and slope of 10-40˚
Over story tree species was injurious insect whit the height of 9-13m and the crown coner of 40-90%. Soil pH ranged from 4.7 to 5.3 and consisted of long and silt loam. Number of plants in the study plots ranged 21 to 63 with mean of 44 species
Over story in the habitat was injurious insect, Styrax japonica, Carpinus tschonoskii, Eurya japonica, Camellia japonica, in middle story, and Smilax china, Rhododendron yedoense var. poukhanense, Ligustrum obtusifolium, in low story.
Milletia japonica was propagated by seeds rather than stolon.
The density of Milletia japonica was dominant in area of good light condition and low crown cover due to human destroy location.
According to cluster analysis, two community Pinus thunbergii community, Pinus thunbergii-Cryptomeria japonica community was classified. Milletia japonica was an annul deciduous liana plant with alternated phyllotaxis.
Length of a small leaf was 1.7-2.7-3.1cm (minimum-mean- maximum) and with was 1.2-1.31-1.5cm (minimum-mean- maximum) Milletia japonica was flowered in July and August and fluted in October and November.
