The paved (tarmac) roads had been constructed on Soqotra island over the last 15 years. The vegetation along the roads was disturbed and the erosion started immediately after the disturbance caused by the road construction. Our assumption is that biotechnical measurements should prevent the problems caused by erosion and improve stabilization of road edges. The knowledge of plant species which are able to grow in unfavourable conditions along the roads is important for correct selection of plants used for outplanting. The vegetation succession was observed using phytosociological relevés as a tool of recording and mapping assambblages of plants species along the roads as new linear structures in the landscape. Data from phytosociological relevés were analysed and the succession was characterised in different altitudes. The results can help us to select group of plants (especially shrubs and trees), which are suitable to be used as stabilizing green mantle in various site conditions and for different purposes (anti-erosional, ornamental, protection against noise or dust, etc.).
