About the guide
Gorse is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts. It is a major agricultural weed in Tasmania and parts of Victoria, and is increasingly becoming a threat as an environmental weed in many national parks and other bushland areas.
In pastoral areas it provides shelter for pests such as rabbits, increases the risk of bushfires because of its flammability, reduces access by forming dense thickets and dramatically reduces stocking rates.
In Tasmania the cost of gorse to the state's woolgrowers in lost production alone has been conservatively estimated at about $1 million annually. In Victoria the costs of gorse to the community in the central highlands region were recently estimated at $7 million over five years.
Control of gorse, like all weeds, is expensive with initial costs of up to $1500 per ha and ongoing follow-up required.
