Influence of inundation characteristics on the distribution of dryland floodplain vegetation communities

摘要: Abstract Semi-arid floodplain vegetation is an essential component of and terrestrial ecosystems due to the wide range services provided for waterbirds, woodland birds, amphibians mammals, together with their contribution natural carbon sequestration. Since overbank flooding has been considered driving factor distribution on floodplains, sustainable water resource management requires a better understanding influence inundation distribution. We examined relationship between four flood-dependant communities associated long term metrics upper Darling River using electivity analysis generalised additive model (GAM) by generating total 10,478 individual maps high spatial resolution over period 29 years. Our results show that dominant are situated differently in relation attributes.
