Abstract
This study was carried out to investigate the flora of Mt. Biseul. The vascular plants collected 10 times(from May 2006 to October 2007) were identified as 468 taxa in total, including 89 families, 302 genera, 397 species, 1 subspecies, 59 varieties and 11 forms. Korean endemic plants of this area were identified as 17 taxa including Thalictrum uchiyamai, Coreanomecon hylomeconoides, Lonicera subsessilis, etc.; the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as one taxon including Aconitum austrokoreense; the Office of Forestry-designated rare & endangered plants were identified as 6 taxa including Viola albida, Lloydia triflora, Streptopus ovalis, etc.; the naturalized plants were identified as 34 taxa, and their naturalization ratio and urban index were found to be 7.3%, and 12.2% respectively. This study newly identified about 160 taxa of the plants, among which 17 taxa were newly added to the list of naturalized plants, such as Phytolacca americana, Dicentra spectabilis, Lepidium apetalum, Medicago lupulina, Euphorbia supina, Ambrosia artemisiifolia, Cosmos bipinnatus, Crassocephalum crepidioides, Galinsoga ciliata, Rudbeckia bicolor, Sonchus oleraceus, Tagetes minuta, Taraxacum officinale, Chloris virgata, Festuca arundinacea, Lolium perenne, Tradescantia reflexa, etc. There existed many kinds of plants resources having conservational value like Aconitum austrokoreense etc. in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.
본 연구는 대구광역시 비슬산(1,083m)의 식물상을 조사하기 위해 수행되었다. 2006년 5월부터 2007년 10월까지 10회에 걸쳐 채집된 관속식물은 89과 302속 397종 1아종 59변종 11품종의 총 468분류군이 확인되었다. 한국특산식물은 자주꿩의다리, 매미꽃, 청괴불나무 등 17분류군, 환경부지정 법적 보호식물은 세뿔투구꽃의 1분류군, 산림청지정 희귀 및 멸종위기식물이 태백제비꽃, 나도개감채, 금강애기나리 등 6분류군으로 나타났다. 귀화식물은 34분류군으로 확인되었으며, 귀화율은 7.3%, 도시화지수는 12.2%로 나타났다. 본 조사에서 새롭게 확인된 식물은 160여 분류군이며, 이중에 귀화식물은 미국자리공, 금낭화, 다닥냉이, 잔개자리, 애기땅빈대, 돼지풀, 코스모스, 주홍서나물, 털별꽃아재비, 원추천인국, 방가지똥, 만수국아재비, 서양민들레, 나도바랭이, 큰김의털, 호밀풀, 자주닭개비 등 17분류군이 새롭게 추가되었다. 본 지역은 세뿔투구꽃을 포함한 보존가치가 많은 식물자원이 분포하고 있으나 무분별한 개발 행위와 많은 탐방객의 출입 등으로 자연파괴가 가속화될 우려가 있으므로 탐방객수 제한이나 자연휴식년제와 같은 관리계획이 수립되어야 할 것으로 판단된다.
