River plants from an Iberian basin and environmental factors influencing their distribution disturbance were significantly related to the species distribution. Species positioned at the axes extremes could be arranged into species groups related to different geographical areas of the river system.

Plant emergence in relation to propagule density for all the species ranged from 24% to 56%, and no differences were found between irrigation and drainage channels. Results are discussed in relation to the established vegetation and the different management and environmental conditions
