As you approach the bridge into the conservation area at Booyong you will find small tuffs of grass called Poa Sieberiana. There are a large number of grass species, 230 different kinds in NSW and ACT alone. Amongst the species of pia there are seventeen native and five introduced species and they are difficult to distinguish, although we are quite certain of this one.

The Poa Sieberiana is a year long perennial and grows to 80cm tall, leaves are long and fine and it flowers from sprint to early summer. It is found in woodlands and forests and more commonly on well drained slopes such as the one at Booyong.
