서울 인왕산의 침입외래식물 특성 및 관리방안

Abstract

This study was carried out for management of the invasive alien plants in Mt. Inwang located in central Seoul. The invasive alien plants are 11 families, 34 genera, 30 taxa, and they are 10.8% of the total vascular plants(314 taxa). The ecosystem disturbed plants designated by the Korea environment ministry are 6 taxa : Rumex acetosella, Lactuca scariola, Ambrosia trifida var. trifida, Ambrosia artemisiifolia, Aster pilosus andEupatoriumrugosum.Inthelife-form, herbaceousperennialsare13taxa(35.3%).Inthecontinent of ori- gin, thespeciesfromAmericaare 20taxa(58.8%). Intheintroductiontime, thespeciesofthirdperiodare14 taxa(41.2%).In thediffusiongrade,5 grade speciesare14 taxa(41.2%)and they arewidespreadspecies.Mt. Inwang was designated as ecological scenery conservation area of Seoul in 2007. But Mt. Inwang is in high danger by the spread of invasive alien plants and ecosystem disturbed plants, due to artificial factors such as development pressure and the occurrence of byway trail. Therefore, Mt. Inwang needs systematic manage- ment of invasive alien plants and monitoring of long-term changes.
