hi Barb if you have the opportunity check out Poa sieberiana at the seepage site downhill of the Acacia floribunda (Acacia floribunda (White Sally Wattle, Gossamer Wattle)) which I currently tackle - there are still a lot of poa sieb. despite grazing and trampling. Perhaps you go for a survey search for Cullen tenax in summer; the poa sieb. should be in flower / seed by then.
