The biota of floodplains has high annual growth and mortality rates, which is advantageous for the rapid colonization of large areas of the floodplain. This allows them to take advantage of shifting floodplain geometry. [19] For example, floodplain [20] trees are fast-growing and tolerant of root disturbance. Opportunists (such as birds) are ...
The flood pulse also increases yields by increasing the surface area of water and showers the land with river biota. Flood plain systems also serve as migration routes, hibernation spots, and spawning locations for many species. [5] For the red-bellied piranha, their two annual reproductive seasons are dependent on the flooding pulse.
The flood pulse concept, developed by W.J. Junk in 1989, further modified by P.B. Bayley in 1990 and K. Tockner in 2000, takes into account the large amount of nutrients and organic material that makes its way into a river from the sediment of surrounding flooded land.

A restoration plan began in 1999 with the goals of reestablishing ecological integrity of the river-floodplain system. [20] The project involves dechannelizing major sections of the river, directing water into reconstructed channels, removing water control structures, and changing flow regimes to restore seasonal flooding to the floodplain. [19]
The ecoregion articles in Wikipedia generally follow the WWF scheme. The WWF ecoregions are based heavily upon the Interim Biogeographic Regionalisation for Australia (IBRA) regionalisation. Like the IBRA, it was developed for use as a planning tool for conservation science, with the goal of establishing a system of nature reserves in each of ...

The following unifying characteristics make the ecology of running waters unique among aquatic habitats: the flow is unidirectional, there is a state of continuous physical change, and there is a high degree of spatial and temporal heterogeneity at all scales (microhabitats), the variability between lotic systems is quite high and the biota is ...
