Floodplain wetland biota exhibit an intrinsic relationship with water whereby flooding is the 'principal driving force responsible for the existence, productivity and interactions of the major
biota' (Junk et al. 1989, p. 10). This book documents the current knowledge base for key biota
and their habitat and water requirements in the Murray-Darling Basin. However, there are
knowledge gaps in our understanding of the associations between floodplain wetland biota and
water, and specific relationships remain amorphous for many genera and species. Information
regarding the water requirements of biota is particularly pertinent since water became a diminishing
resource in the Murray-Darling Basin during the 20th century and is projected to
continue its decline in the 21st century due to greenhouse warming-associated climate change.
