Weeds can have serious negative impacts on the economy and the environment.

They can also negatively impact social and cultural activities such as fishing, boating, swimming, bush walking and hunting.

A weed can be described as any plant growing out of place. Usually, weeds are introduced and spread by people. Most weeds grow in disturbed areas but they can also grow in native bush environments. In some cases, they can even change the landscape.

Weeds can be both a symptom and a cause of land damage.
