|Scientific Name:||Dasyuroides byrnei Spencer, 1896|
Dasycercus byrnei (Spencer, 1896)
|Red List Category & Criteria:||Vulnerable C2b ver 3.1|
|Assessor(s):||McKnight, M., Canty, P., Brandle, R., Robinson, T. & Watson, M.|
|Reviewer(s):||Lamoreux, J. & Hilton-Taylor, C. (Global Mammal Assessment Team)|
Listed as Vulnerable because the population is estimated to be less than 10,000 mature individuals and is subject to extreme fluctuations. It has suffered decline in the past and will likely continue to decline, mainly due to the future impacts of global warming and subsequent range contraction.
|Previously published Red List assessments:|
|Range Description:||The Kowari is endemic to Australia, where it is found on the gibber plains of the Channel Country in southeastern Queensland and northern South Australia (Lim 2008).|

|Population:||This species is rare and scattered with low densities (Lim 2008). Populations fluctuate with climatic conditions (Lim 2008). Estimates of total population are based on area, maximum density and the fact that there are 24 known populations (although probably less now as some populations are thought to have recently disappeared; Canty and Brandle 2008). The total adult population is probably less than 10,000 individuals (P. Canty pers. comm.).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Kowaris inhabit stony gibber plains with sparse scrub between braided river channels and sand dunes in Channel Country (Lim 2008).|
|Major Threat(s):||Kowari numbers have declined in areas where livestock grazing is intense, and their occurrence has diminished near water holes used by stock. The affects of introduced predators on this species is unknown. Global warming has the potential to be a threatening process for this species. Modelling by Chapman and Milne (1998) for the Kowari predicted a severe contraction in range.|
|Conservation Actions:||The Kowari is listed as a threatened species under Australian law. It occurs in a few protected areas including Diamantina and Astrebla Downs National Parks.|
