Analysis of landslides revegetated with autochthonous seeds in the National Park "Foreste Casentinesi, Monte Falterona and Campigna", Tuscany. In activities aimed to grass cover restoration of landslides, the use of seed mixtures of local, autochthonous species instead of common forage species is a technical choice that faces two difficulties: the scarce availability of seed material and its high costs. For these reasons their utilization is commonly restricted to situations characterized by

... h ecological or aesthetic value. This paper reports the results of a study carried out on several landslides revegetated in different years of an area located within the "Foreste Casentinesi, Monte Falterona and Campigna" National Park. In these sites the revegetation activities were performed using a mixture of native seeds collected from close natural grasslands. The aim of this work was to evaluate the success of the grass cover recovery and to obtain information on the evolution of species composition in the restored plant community. Data collection was aimed to assess the ground cover, the presence of the different species, the floristic richness and the recolonization by autochthonous species. Results showed a fairly good success in the recovery and a strong persistence of a single species largely represented in the original mixtures (Festuca gr. rubra). Evidence reported here suggests that plant community evolution is strongly dependent on local environmental conditions.
