정읍 신정동 연구단지 및 RFT산업단지 주변 외래식물 현황

Abstract

In Shinjeong-dong of Jeongeup, there are three government-supported researchinstitutes and an RFT industrial complex which is currently being established. Increased humanactivities can affect flora and fauna as a man-made pressure onto the region. As a baseline study,status of exotic plants was investigated prior to a full operation of the RFT industrial complex. A total of 54 species and 1 variety of naturalized or introduced plants were found in the studyarea. Among them, three species (Ambrosia artemisifolia var. elatior, Rumex acetocella and Asterpilosus) belong to ‘nuisance species’, and four species (Phytolacca americana, Iopomoea hederacea,Ereechtites hieracifolia and Rudbeckia laciniata) to ‘monitor species’ designated by the ministryof Environment. Some of naturalized trees and plants were intentionally introduced in this area,while others naturally immigrated. Physalis angulata seemes to immigrate in the study area in theform of mixture with animal feeds as its distribution coincided with the transportation route of theanimal feeds. Liquidambar styraciflua is amenable to the ecological investigation on the possibleexpansion of the species to the nearby Naejang National Park as its leave shape and autumncolor are very similar to those of maple trees. The number of naturalized plants around the RFTindustrial complex will increase with an increase in floating population, in human activities inassociation with constructions of factories and operations of the complex. The result of this studyprovides baseline data for assessing the ecological change of the region according to the operationof the RFT industrial complex.
