Vegetation, environmental characteristics and soil analysis of Megaleranthis saniculifolia
Ohwi habitats were investigated to propose the basal data for conservation and restoration. M.
saniculifolia was distributed around an altitude of 770~1,440 m with an inclination of 0~20℃, and
mostly formed discontinuous populations in northern part of valley. The vascular plants from 78
quadrates of 11 habitats were identified 111 taxa. Importance value of M. saniculifolia was 27.05%,
and highly ranked 5 species such as Veratrum oxysepalum (5.67%), Corydalis turtschaninovii (5.32
%), Aruncus dioicus var. kamtschaticus (4.35%), Meehania urticifolia (4.06%) and Anemone koraiensis
(3.91%) were considered to be an affinity with M. saniculifolia. Dominant species of woody
plants in 78 quadrates were represented as Cornus controversa, Juglans mandshurica, Quercus
mongolica, Acer pseudo-sieboldianum and A. mono in tree (B1) layer, A. pseudo-sieboldianum and
Carpinus cordata in subtree (B2) layer, Deutzia glabrata and Prunus padus in shrub (S) layer. Average
species diversity was 1.16, and dominance and evenness were found to be 0.12 and 0.81, respectively.
Average field capacity was 26.41%, and the organic matter and soil pH were 7.83% and
5.83. Correlation coefficients based on environmental factors, vegetation and soil analysis were
showed that the positive correlations between slope degrees and pH, slope degrees and organic
matter, dominance and importance value, species diversity and richness, whereas between species
diversity and dominance, and importance value and dominance were showed negative correlations.
