Wetland complexes in the Murray-Darling Basin identified as priorities when setting an 80% representation targets for each of the 52 waterbird species, simultaneously across all species, across all years (overall), during dry and wet years, along with total and average (±95% CI) waterbird abundances estimated during the aerial surveys of waterbirds in eastern Australia.
