Natural revegetation on road-sides of hill roads (Iberian System, La Rioja, Spain)
AbstractIn this paper the authors describe the dynamic and the spatial organization of the natural revegetation on road-sides of hillroads. They show the existence of significant differences in the percentage of vegetal cover between the road-cuts (F1) and the debris of the first meters downslope of the road (F2), and they establish the recolonization strategies. Altitude, road-sides gradient, and erosion processes are very influential in the develop of the revegetation.
