Resumen:
We have evaluated the level of restoration achieved by a technical revegetation action carried out on reconstructed foredunes at the Devesa de la Albufera and compared this level with that achieved by spontaneous succession. Foredunes 1, 3, 6 and (20 years old since revegetated (1, 3, 6 and 20 yr, respectively) were considered as spatially separated stages representing a successional trend in the development of the restored plant community. Lower and similar levels of diversity (richness and H´ and Pielou´s indexes) and coverage, respectively were found on dunes corresponding to the oldest stage of technical revegetation compared with that of the reference site. Diversity and coverage parameters increased during the first 6 years of the technical succession and decreased after 20 years of revegetation. Moreover, that increase was quite obvious as early as three years after the onset of revegetation. Results also showed that the Devesa de la Albufera has its own capacity for revegetation. According to the Jaccard and Sørensen indexes, these dunes were more similar to the reference than those from the 20 yr site. Beyond the current functionality of the revegetated sites, it is concluded that the natural and aesthetic values may be restored at the Valencian Devesa de la Albufera.
