|
This study was carried out to establish the conservation plan of specific plants by surveying and analyse the individuals and
the environment of habitats on specific plants designated by Juwangsan national park office. The specific plants were 14
species including Berchemia berchemiaefolia, Hylotelephium ussuriense, Aristolochia manshuriensis, Lilium cernuum,
Thalictrum coreanum, Exochorda serratifolia, Lilium distichum, Aristolochia contorta, Jeffersonia dubia, Eleutherococcus
senticosus, Salix chaenomeloids, Eranthis stellata, Scopolia japonica, and Paeonia japonica. The habitats of specific plants were 40 sites including Berchemia berchemiaefolia of 11 sites, Hylotelephium ussuriense of 8 sites, Lilium cernuum and Thalictrum coreanum of each 3 sites, Exochorda serratifolia of 2 sites, and Lilium distichum, Aristolochia contorta,
Jeffersonia dubia, Eleutherococcus senticosus, Salix chaenomeloids, Eranthis stellata, Scopolia japonica and Paeonia
japonica of each 1 site. The altitude was the most in 300～400 m. In direction, NW was the most, and it showed SW in that
order. The slope angle was the most in 0～10%, and the cliff showed in that order. In the results of species composition by
stratum layer, Berchemia berchemiaefolia had the most, 15 species, in tree layer. In shrub and herb layer, this had the most as 20 species and 29 species, too. The species that occupied the largest size was Salix chaenomeloids in 2,500 ㎡, and Jeffersonia dubia showed 1,500 ㎡in that order. The conservation of specific plants is to accomplish the ex situ and in situ conservation at the same time.
