Abstract

Most evergreen Quercus species are typical, dominant members of Korean evergreen forests. However, little is known about the distribution status of Q. myrsinifolia Blume there. To enhance our knowledge about their natural range in Korea, we conducted field surveys based on specimen records and an extensive literature search. We also determined their exact number as a first step in planning their conservation. The results indicated that these trees are strictly limited to Jin Island, and 169 mature individuals were the maximum number and occurred in only three subpopulations on that island. Previous misidentifications and perhaps mislabeled locations for plant specimens were the main reasons for earlier confusion about distribution. We believe that these results can provide guidance when making specific recommendations for management interventions. These discoveries also demonstrate the value in having reliable information about plant specimens in general. We also speculated about what makes this species particularly vulnerable to local extinction.

상록성 참나무류는 한반도 상록활엽수림을 구성하는 주요 수종으로 알려져 있다. 그러나 가시나무(Quercus myrsinifolia Blume)의 한반도 분포지와 자생현황은 명확히 밝혀져 있지 않다. 본 연구에서는 문헌조사와 표본에 근거한 현지조사를 토대로 가시나무의 자생지를 밝혀 한반도 내 분포를 명확히 하고자 하였다. 또한 보존대책의 첫 단계로 자생 개체수 전수 조사를 실시 하였다. 조사결과, 한반도 내에서 가시나무는 전남 진도에 단 3개의 아집단으로 구성된 169개의 성체만이 제한적으로 자라는 것으로 확인되었다. 본 연구를 통해 오동정과 식물표본의 채집지 오기재가 종의 분포에 대한 혼란을 야기하는 주된 원인임을 알 수 있었다. 금번 조사결과는 한국산 가시나무의 효과적 보전을 위한 중요한 지표자료로 활용할 수 있을 것이다. 또한 식물표본의 정확한 데이터 기재의 필요성을 확인할 수 있다. 한편 본 논문에서는 한반도에서 이 종의 분포가 진도에만 제한되게 된 원인에 대해 논의 하였다.
