Acacia in bioretention


Hi there,

The subject of today’s episode has been working around in my mind for a while now, so when I got the opportunity to share it with you I couldn’t pass it up. As we get more and more bioretention systems in South East Queensland I have seen more and more acacia trees popping up in them. In fact in some in cases they pop up really quickly.

Acacia’s are a pioneer species. In nature this means when an old tree dies, acacias grow quickly where the tree once stood. They take advantage of the new space. They grow rapidly and die relatively young (for a tree). These properties make me think that there is a real place for them in bioretention systems, and with them popping up of their own accord all over the place I think that they are worth considering.
