Ephemeral streams are the most abundant stream type in the American Southwest. Their riparian zones have more woody plant biomass, but similar herbaceous cover, than terrestrial zones. Ephemeral stream riparian zones support more plant species than terrestrial zones. Increasing aridity will reduce herbaceous species richness and cover and favor annuals over perennials. Increasing aridity will convert riparian savannah to xeroriparian scrubland.
