Population justification: Despite the Riverland Biosphere Reserve (formerly the Bookmark Biosphere Reserve) supporting an estimated 3,760 individuals, this is thought to equate to an effective population size of only 390 (210-726) mature individuals owing to a skewed sex ratio and a complex social organisation (Clarke et al. 2005). This population represents over 95% of the total effective population, hence, given the broad confidence intervals the population is probably best estimated to fall within the band 250-1,000 mature individuals. The surveys for the estimates by Clarke et al. (2005) were carried out following a series of good breeding seasons, and the population may now stand at the lower end of the estimates owing to a drought in the region (R. Clarke in litt. 2007). Garnett et al. (2011) suggest a total population of 500 mature individuals.
Trend justification: It is suspected to have declined dramatically owing to clearance and fragmentation of its preferred mallee habitat. As a result, hybridisation with the dominant M. flavigula, which invades remnant habitat patches, is now the greatest threat and continues to drive declines. A recent drought may have affected the population and a fire in the Bookmark Biosphere Reserve in late November and early December 2006 burnt 115,000 ha of mallee habitat, reducing the area of available habitat for the species by about a third, or possibly more (R. Clarke in litt. 2007).
