Verbreitung und Lebensraum

The Naretha bluebonnet is reported to have been common in the arid Nullarbor region, and became rarer during the 20th century. The localised range of individuals is thought to make the species highly endemic to an area on the border of Western and South Australia.Narethas are located in what is termed the Myall woodlands - this is a woodland dominated by acacia species.The Naretha homelands extend over a large and isolated range. They are often observed more readily in areas where water has become an altered focal point - notably water troughs for stock.
