The identification of vegetation on the Siak river’s corridor as long as desa Merempan Hilir to choose the plants to make the eco – engineering withoutcivil construction’s design has been done. Some kind of plants have been choosen i.e :rumput teki (Cyperus rotundus), rumput kumpai (Hymenachne acutigluma) rumput akar wangi (Vetiveria zizanioides), karangkunan (Ipomea carnea), bambu kuning (Bambusa vulgaris), pandan (Pandanus, sp), bintaro (Cerbera manghas), rengas (Gluta renghas),kempas (Koompassia malaccensis), jawi – jawi (Ficus, sp) and meranti (Shorea, sp).Key words : desain eko – engineering tanpa turap, perlindungan tebing, tanaman lokal
