What is an environmental weed?
Environmental weeds are introduced plants that have naturalised and invaded our bushland, beaches and waterways, threatening our natural environment.
Many environmental weeds were originally introduced and grown as ornamental garden plants. Most environmental weeds are not native to Australia, but some native plants have also become environmental weeds after spreading outside their natural range.
Weeds are usually very hardy plants. They may grow very quickly, reproduce in large amounts and are often tolerant to a wide range of conditions. It is these qualities that make weeds so successful and also make them difficult to control. Weeds commonly thrive where there has been a disturbance to the natural system such as changes in light, nutrients, soil or hydrology. The spread of weeds can be due to animals, wind, water and human activities.
The City of Gold Coast has produced an Environmental Weeds booklet which aims to help residents identify weeds and provides information on how to control environmental weeds.

Controlling environmental weeds
The appropriate weed control method or combination of methods will depend on a range of factors including:
- the aim of your project
- surrounding plants, landscape and land use
- size and growth habit of plants to be controlled
- scale and density of the weed infestation
- other weed species impacting the site
- seasonal and weather conditions
- habitat considerations and surrounding native vegetation
- safety considerations
- available resources including follow up and maintenance
- level of skill and experience of the people carrying out works.
It is important to note that weeds are usually the first plants to re-establish in an area after initial weed control is carried out. Successful long term weed control requires planning, working methodically, and ensuring follow up control and maintenance is ongoing.
