제주 오름의 식생과 교육적 활용

Vegetations survey was carried out at the parasite volcanoes such as Sarah Orum, Mulchat orum, Bulkeun Orum-A, Bulkeun Orum-B, Yiseungak Orum, Mul Orum, Malchat Orum and Semiyang Orum located at Jeju Island, and an educational application for visitors was attempted. Vegetation composition was classified into four communities by Braun-Blanquet method and the floristic composition was also compared according to the presence or absence of visitor’s routes, grazing, reforestation and timbering by means of setting up the three transect belts. Plants inhabiting along the visitor’s routes was severely damaged by trampling and thus visitor’s trampling gave rise to decrease plant diversity. In addition, grazing by liver stocks was also disturbed Orum’s ecosystem and it was known that Rumex acetocella which is one of ecosystem disturbed species in grazing area was invaded to the perturbed area near Pinus thunbergii forest. The damage of vegetation by visitor’s trampling will be a problem to be considered and it needs to change the visitor’s mind for ecosystem conservation of volcanic Orums. Accordingly, the authors suggest that visitors of Orums will need some prerequisite education on nature conservation and information of ecological background before the course starts.
