Content: A possible approach to prevent and control soil erosion in mountain regions after the vegetation has been damaged or destroyed by natural or man-caused events is represented by the seed propagation of indigenous alpine species in lowlands and their use in seed mixtures for revegetation. Two different aspects of this approach are investigated here: first, the feasibility of the organic seed propagation of some alpine species (Trifolium alpinum, Sesleria albicans and Festuca nigrescens), including some additional investigations about the effect of substrate, soil micro-organism and pathogens on the growth of Trifolium alpinum. Furthermore, results of a case study are reported about the use of seed mixtures containing alpine species for the restoration of ski runs in combination with environmentally sound revegetation techniques (partial conservation of the topsoil and reduction of fertilisers input), aiming also to promote spontaneous processes of re-colonization of the autochthonous vegetation.
