Natural revegetation on road-sides of hill roads (Iberian System, La Rioja, Spain)

V. Larrea, J. Arnáez Vadillo, L. Ortigosa


In 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.
