Grass-trees in Canadian Regional Park

Two grass-trees grow in Canadian Regional Park. Austral Grass-tree Xanthorhoea austalis is wide spread in the park with Small Grass-tree Xanthorhoea minor in a few areas. In some areas these two species grow in close proximity.

Austral Grass-trees develop a trunk as they grow where as the Small Grass-tree stem is mainly below ground level.

Other differences

Flower spike Flowering section longer than stem. Flowering section shorter than stem.
Leaf cross-section Diamond shape. Triangular shape.
Leaf colour Blue-green with whitish bloom. Green.

Cool Burn

 

Parks Victoria conducted a cool burn in Canadian (Woowookarung) Regional Park on 9 May 2017. The crew involved are commended for the environmental awareness.

Austral Grass-trees were individually ignited. The fuel load was reduced by burning the dry skirts without damaging Common Heath flowering near by.

This should reduce the heat of future burns and prevent the damage done to hollow trees as seen in a hot burn in 2015.
