Sydney Golden Wattle Acacia longifolia
Acacia longifolia, or Sydney Golden Wattle, continues to be a pest throughout the region. The time of year is approaching when it starts making a showy yellow statement in the landscape. A perfect time for locating and removing these woody weeds. WICC has made significant progress in controlling this wattle in the upper catchment in collaboration with Pardelup Prison. Denmark Weed Action Group has consistently worked on its removal in the lower catchment, while Green Skills currently have funding for weedy wattle removal across the Great Southern.
Because it fixes nitrogen in the soil, it is a pathway to weedy grasses moving into farmed and bushland areas. The ideal control time is before seed sets. Fell as close to ground level as possible to prevent resprouting and remove material from site to prevent vegetative regrowth. Small plants can be hand pulled, loosening the soil if need. An annual follow up seedling check is required.
Chemical controls can be applied depending on the situation of the infestation. Eg a thick area of seedlings could be sprayed with a 10% glyphosate solution. Contact WICC for further info.
