Studies on the Vertical Distribution of the Corticolous Lichens in the Mt. Sobaeg.

소백산에 있어서 지의류의 수식분포에 관한 연구

The vertical distribution of the corticolous lichens in Mt. Sobaeg was detected by 10cm point quadrat. The dominant species of lichens was arranged in a single dimensional ordination along the elevational gradient with the frequency percentage of the species. Cetraria stracheyi, Parnaria leucosticta, Stieta platyphyll and Parmelia petusa were found in order of abundant from lower, Samgadong(400m) to higher, Birobong(1439m) in which they occurred mainly on the southwest slope. However, such species as Cetraria juniperina was more abundant than Parnaria leucosticta and Stieta platyphylla at the southeast slope. The distribution of Cetraria Stracheyi and Parnaria leucosticta was limited below 1200m height, while Parmelia petusa and Cetraria juniperina mostly above 900m height.
