Weed Management

What is a Weed?

Weeds may be either introduced plants, or native plants growing outside their natural range.

A weed is a plant which has, or has the potential to have a detrimental effect on economic, social or conservation values. (National Weeds Strategy, 1997)

Weeds invade or take over ecosystems and are not in balance with other flora and fauna in that ecosystem.

Many ornamental plants growing in backyard gardens have the potential to become environmental weeds in local bushland.

Identification and Management

Knowing what plants are weeds in the City, can assist in reducing their impact on local bushland.

The attached Guides provide information on types of plants which are weeds in this area (or have the potential to become weeds), their appearance and dispersal methods. High resolution, colour photographs assist in identification.

The Guides also outline tips for managing the spread of weeds and purchasing and growing local, native plants - a great alternative for your backyard garden that is in tune with the natural environment.

Hard copies of the Guides are available from the City Adminstration Building, Libraries and Community Centres. 

See the City of Joondalup Guides 'Growing Locals' for more information on local, native species.
