A range of teacher professional learning programs will be developed to accompany the Biodiversity of the Western Volcanic Plains online outreach...
Perennial. The developing seeds are eaten by native finches and sparrows. Sheep preferentially graze on the more nutritious Kangaroo Grass Themeda triandra, leaving the tougher Spear-grasses to grow and dominate the vegetation. Mowing nature reserves, road and railside reserves can cause the same effect. The seeds of Spear-grasses have long awns (bristles) that can work their way into the skin, mouths and eyes of stock, and can also contaminate wool. Kneed Spear-grass can look very like the introduced Chilean Needle Grass Nassella neesiana and Cane Needle Grass Nassella hyalina at certain times of the year, so care must be taken not to eradicate this native grass when trying to control the noxious Needle Grass weeds.
The stems (culms) disintegrate after the seed heads develop. By early winter some stems start to split and fray until the stem tops are wispy tangles of fibre blowing in the wind. The seed has a 4.5-9 cm long awn (bristle) that bends twice.

|DEPI Advisory List||
The conservation status of species is listed within Victoria and Australia.
The Department of Environment and Primary Industry (DEPI) Advisory List consists of non-statutory advisory lists of rare or threatened flora and fauna within Victoria.
The Flora and Fauna Guarantee Act 1988 (FFG Act) lists threatened species in Victoria. Under the Act, an Action Statement is produced for each listed species.
The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is the Australian Government’s key piece of environmental legislation, listing nationally threatened native species and ecological communities.
