All native Australian Stipa are now relegated to the new genus Austrostipa . Austrostipa mollis is widespread on sand and/or low nutrient soils in the southern states of southern New South Wales, Victoria and South Australia, and separate populations in south-west Western Australia and Tasmania . It is a very common component in sandy coastal heathlands . In general, Austrostipa species have a high frost and drought tolerance and populations decrease with increases in grazing intensity or soil fertility levels .
Flowering and seeds
It flowers in spring to summer [16, 43, 44] or in response to rain . As Austrostipa mollis is a C3 temperate winter grass, propagation (using fresh seed) in autumn or early winter when air temperatures are in the 12-25°C range is recommended [93, 114].
Cultivation and uses
Of moderate to low value as stock feed . There is a risk of seed burrowing into stock, so paddocks with this grass in seed are best avoided at this time. Its stock values decreases sharply as it ages, so if managed by burning or grazing fresh growth will be promoted (pers. comm. Paul Gibson-Roy, Grassy Groundcover Project].
