Native Plants Selection for Ecological Replantation in Forest Road Slope - In case study on forest road of Gangwon-do -

임도사면의 생태적 녹화를 위한 자생식물 선정 - 강원도지역 임도를 중심으로 -

This study was carried out to select proper species for early stage replantation of forest road cut-slope. From one to fourteen year elapsed forest roads in Gangwon-do, sample plots were selected, and their vegetations and environmental factors were investigated. Invaded species with high frequency ordered Lespedeza cyrtobotrya, Lysimachia clethroides, Rubus crataegifolius, Patrinia villosa, Spodiopogon sibiricus, Pueraria thunbergiana, Youngia denticulata, Dactylis glomerata, Rhus chinensis, and Pinus densiflora. North cut-slope have the highest value of invaded species number and plant coverage, and so, north aspect could be best for plant invasion. According to ordination, distribution of species were influenced by elapsed year, cut-slope aspect, and cut-slope. Lespedeza bicolor, Lespedeza cyrtobotrya, Artemisia stolonifera, Miscanthus sinensis, Rubus crataegifolius, Rhus chinensis, Lindera obtusiloba, and Pinus densiflora were considered with proper species for replantation at south slope. Also, Lespedeza bicolor, Lespedeza cyrtobotrya, Arundinella hirta, Artemisia keiskeana, Astilbe chinensis var. davidii, Rubus crataegifolius, Weigela subsessilis, Stephanandra incisa, and Rhododendron mucronulatum were considered with proper species as replantation at north slope.
