AB Riparian zones are among the natural habitats more prone to be invaded by exotic plants. In this study we review the causes and  consequences of these invasions on fluvial and riparian ecosystems, as well as the effects described for the Iberian Peninsula  so far. Riparian zones receive a high propagule pressure of exotic plants, their abiotic conditions are benign for plant life, and  their biotic resistance from native vegetation is released by natural (floods) and anthropic (hydrological changes) disturbances.  The convergence of these factors explains the high invasion rate of riparian zones. An eventual replacement of native by nonnative  vegetation might alter the fire regime, the depth of the water table, nutrient cycles and organic matter processing,  soil properties, communities of detritivore invertebrates and vertebrates dwelling in rivers and riparian zones. In the Iberian  Peninsula we found that the effects of non-native riparian plants were more often negative (e.g. alteration of the structure  and activity of microbial communities) than neutral (e.g. similar decomposition rate between native and non-native litter),  and rarely positive for primary production (e.g. faster litter decomposition). Our review also highlights a strong bias in the  selection of target non-native species (mostly Eucalyptus globulus, Ailanthus altissima and Robinia pseudoacacia) and in  the studied effects (mostly litter decomposition and structure and activity of microbial communities). Therefore, a reliable  evaluation of the effects of non-native plants in Iberian riparian ecosystems requires extending the number of studied species   and of response variables.
