Conservation of an Endangered Corylopsis coreana Uyeki in and ex situ and Development of Cooperative Model within Local Community - III. Populational Comparison Between Natural Groups and Deforestation Groups of Corylopsis coreana UYEKI
히어리의 자연집단과 벌채집단간의 비교는 전라남도 순천시 승주읍 접치재, 월등면, 황전면, 경상남도 진주시 명석면, 경기도 포천시 백운산 5곳의 벌채지와 주변 자연림에 분포하는 히어리군락을 대상으로 비교하였다. 100m2당 맹아수와 개체당 평균 맹아수는 벌채 집단에서 자연집단의 것보다 더 높게 나타났다. 반면 맹아수별 수고와 직경은 자연집단에서 더 높게 나타났다. 종조성과 식생상관성은 없으며 벌채집단과 자연집단 모두에서 큰차이 없이 생육하였다. 개괄지인 벌채집단에서 근맹아 뿐만 아니라 실생묘로도 번식하였다. 이처럼 히어리는 환경적응력이 커서 인간이 훼손시킨 벌채집단에서 근맹아와 실생묘로 번식함으로써 종 자체의 소멸은 없고, 오히려 일시적인 교란이후에 개체군 확장을 보였다.
The comparison of Corylopsis coreana populations between natural groups and deforestation groups is carried in five regions such as Seungju, Woldeung, Hwangjeon in Suncheon, Myeongseok in Jinju and Mt. Baegun in Pocheon. The number of sprouting per both 100m2 and each individual stump were appeared more in deforestation than in natural groups. In contrast, the height and the diameter of individuals by the number of sprouting are higher and larger in the natural groups. The relationship between the floristic composition and vegetation in the two groups of C. coreana populations was not appeared. Corylopsis coreana are propagated sprouting as well as seedling in deforestation groups located an opening area. Because of the powerful environmental adaptability through growth of the sprouting and the seedling in deforestation groups, the population of C. coreana are not extinction of species oneself, and on the contrary are showed expansion of C. coreana population after temporary disturbance.
