초록

파초일엽 자생지는 1949년 제주도 삼도에서 최초 발견된 이후 학술적 가치가 인정되어 1962년 12월 천연기념물 제18호 지정되었다. 우리나라에서는 제주도 삼도에서만 자생하며, 해방이후 땔감, 도취 등으로 자생지가 크게 훼손되어 거의 멸실에 이르렀으나 이식, 복원을 통해 명맥을 유지하고 있다. 대상지는 2011년부터 공개제한구역으로 관리되고 있으며 2000년대 자생지 복원 이후 약 20년이 지난 시점에서 파초일엽 생육실태 변화상에 대한 모니터링과 자생지 관리를 위해 이식, 복원의 기원 등 주요 관리이력에 대한 공식적인 기록 확인이 필요한 상황이다. 본 연구 결과 지정초기부터 현재까지 자생종 판별, 이식 복원 기록 등 문화재 관리이력을 확보하였고, 복원 이후 약 20년이 지난시점에서 파초일엽 생육변화상을 살펴보았다. 파초일엽 자생지 복원 이력을 살펴보면 1970-80년대에 이식된 개체들은 공식문서가 없었으며 1974년 복원 이식한 개체는 당시 일본 개체로 판단되어 자생종에 대한 논란이 있었다. 파초일엽 자생종 판별 연구를 통해 유전적으로 자생종으로 판명된 개체를 증식하여 2000년 156본, 2001년 150본을 이식하고 육묘장을 2004년 조성하여 파초일엽을 증식하였다. 자생지 내 파초일엽 생육지는 2곳으로 지점 1은 석축 위에 65개체가 3단에 나누어 밀식하여 자라고 지점 2는 29개체가 2열로 자라는 형태로 조사되었다. 파초일엽이 생육하고 있는 지역의 식생은 참식나무가 우점하는 상록활엽수림지대이며, 조사지점 외 자생 파초일엽 개체는 발견하지 못하였다. 본 연구의 특기할 만한 사항은 복원 후 최초로 자연 발생한 파초일엽 치수의 분포현황을 확인한 점이다. 치수 개체는 약 300개체 이상이었으며, 이 중 밀도가 높은 지점을 중심으로 모니터링을 위한 고정조사구 3개소를 선정하였다. 모니터링 1지점의 파초일엽 치수는 23개체로 개체당 잎수는 4~17장, 길이는 0.5~20 cm이었으며, 2지점은 88개체로 개체당 잎수는 5~6장 길이는 1.3~10.4 cm이었으며, 지점 3은 22개체로 잎 수 5~9장, 잎 길이 4.5~12.1 cm로 나타났다. 파초일엽 자생지는 2011년 공개제한 지역으로 설정되었으나 낚시, 스쿠버행위 등 일부 행위가 허가됨에 따라 자생지의 훼손 발생가능성이 크므로 법의 엄격한 적용과 함께 문화재 보존을 위해 충분한 교육과 문화재에 대한 정확한 정보 전달이 이루어져야 할 것이다.

A. antiquum, first observed in Jeju Samdo Island in 1949, was designated as the Natural Monument No. 18 in December 1962 in recognition of its academic value. In Korea, it grows in nature only in Samdo in Jeju Island. Although its natural habitat was greatly damaged and almost destroyed due to firewood, stealing, etc. After the emancipation, it has been maintained by the transplantation and restoration. The site observed by this study has been managed as a restricted area since 2011. Since it has been about 20 years since the restoration of the native site in the 2000s, it is necessary to check the official management history records, such as the origin of transplantation and restoration to monitor the changes in the growth status and to control the habitat. As the results of this study, we have secured the records of cultural property management history, such as the identification of native species and the transplantation and restoration records. We also examined the change of the growth and development of A. antiquum 20 years after the restoration. There are no official records of the individuals transplanted to the restored natural habitat of A. antiquum in the 1970s and 1980s, and there was a controversy about the nativeness of those individuals that were restored and transplanted in 1974 since they were Japanese individuals. The studies of identifying native as the results of this study, we have secured the records of cultural property management history, such as the identification of native species and the transplantation and restoration records. We also examined the change of the growth and development of A. antiquum 20 years after the restoration. There are two sites in natural habitat in Samdo Island. A total of 65 individuals grow in three layers on three stone walls in a site while 29 individuals grow in two columns in the other site. A. antiquum grows in an evergreen broad-leaved forest dominated by Neolitsea sericea, and we did not find any other individuals of naturally growing A. antiquum outside the investigated site. This study checked the distribution of A. antiquum seedlings observed initially after the restoration. There were more than 300 seedling individuals, and we selected three densely populated sites for monitoring. There were 23 A. antiquum seedlings with 4 - 17 leaves per individual and the leaf length of 0.5 - 20 cm in monitoring site 1. There were 88 individuals with 5 - 6 leaves per individual and the leaf length of 1.3 - 10.4 cm in monitoring site 2 while there were 22 individuals with 5 - 9 leaves per individual and the leaf length of 4.5 - 12.1 cm in monitoring site 3. Although the natural habitat of A. antiquum was designated as a restricted public area in 2011, there is a high possibility that the habitat can be damaged because some activities, such as fishing and scuba diving are allowed. Therefore, it is necessary to enforce the law strictly, to provide sufficient education for the preservation of natural treasures, and to present accurate information about cultural assets.
