Not to be confused with our own Golden Wreath Wattle (Acacia Saligna), Eastern States Wattles have become problematic in the South West due to their previous popularity as ornamental trees & as soil stabilisers. Weed Wattles are not a problem in their own natural geographic locations where local seed-eating insects keep them in check, but this natural control does not occur in Western Australia where these wattles reproduce prolifically by seed.
Why is that a problem? Wattles are nitrogen fixers. When they grow in an area that has been disturbed, the combination of disturbed soil and extra nitrogen encourages exotic grasses to invade. As the grasses dry out in summer, they increase the risk of bushfire. Fire stimulates more wattle seeds to germinate and a destructive cycle is set in motion. In addition, under optimum conditions weed wattles can form dense, almost impenetrable thickets of trees effectively, wiping out all other native plants and habitat for native animals.
All in all we don’t want them around!
In this practical demonstration workshop presented by well known local ‘weed warrior’ & contractor Rick Ensley from Margaret River Naturals, participants will learn how to identify the different types of weed wattles and some other woody exotic species common to the Lower Blackwood, AND some tips and tricks on how to deal with them using readily available tools.
