The influence of flood frequency, geomorphic setting and grazing on plant communities and plant biomass on a large dryland floodplain

►We examine how flooding, geomorphic setting and grazing affect floodplain vegetation. ►In the long-term flood frequency is the primary determinant of community composition. ►In the short-term, wetting history and grazing influence plant biomass. ►Wetting history and grazing have a smaller influence on community composition.
