The purpose of this study is to provide basic data for the sustainable maintenance and management of agricultural fill dams by examining the naturally transmitted vegetation in downstream slope. The relative frequency(RF), relative density(RD) and importance value(IV) of each major plant species of the reservoir to be studied based on the results of the field vegetation survey targeting the vegetation on the downstream slope of the agricultural field dam. By calculating, the ecological impact of constituent species was quantitatively evaluated, and top ranking of plant species(TROPS) by reservoir was selected and applicability was suggested. Silver grass is proposed as a protection plant on the downstream slope of an agricultural fill dam by reflecting the TROPS selection results of silver grasses and the social demand for using silver grasses. Silver grass is a native perennial plant that is native to Korea, so there is no risk of disturbing the ecosystem, and the lush silver grass forest serves as a habitat for wild birds or mammals, so it is a plant that has a beneficial effect on the ecological environment. Silver grass is widely used for regional festivals, tourism topics, various folk materials, construction materials, and bio-energy raw materials. It also can be used as an important material for vitalizing the area around the reservoir.
