Weeds & Garden Waste
Weeds are among the most serious threats to Australia's natural environment. They can also degrade agricultural landscapes, and interfere with human health and recreation. In Queensland, weeds are estimated to cost $600 million annually.
A weed can be an exotic species or a native species that colonises and persists in an ecosystem in which it did not previously exist and requires some form of action to reduce its effect.
Weeds can inhabit all environments from our towns and cities through to our oceans and many of the weeds we see invading vegetation along roadsides or on the edges of bushland were originally planted in urban gardens.

Useful Tips and Facts
- Create urban wildlife corridors and stepping stones to larger local bushland or parkland areas.
- In nature there is no such thing as waste everything is linked and contributes to the cycle. As a plant reaches the end of its life cycle it is not discarded by nature, instead it provides habitat for animals and food for micro-organisms as it lies on the ground, the waste from the micro-organisms, bacteria and fungi feeding on it replace nutrients and organic material to the soil for new plants to grow.
- Plant local native species
- The best way to attract native wildlife to your backyard is to provide a variety of healthy natural foods in the form of seeds, leaves, flowers, nectar, pollen, fruits and nuts throughout the year.
- The use of pesticides and herbicides can damage your soils and kill non target species. The poisoning of insects with chemicals can also cause larger species relying on those insects as a food source to become sick or even die from eating poisoned insects.
- To create habitat for smaller native birds you can grow shrubs close together to create dense corners or pockets in your garden which will provide protection and refuge from larger aggressive birds such as noisy miners
- Wattles (Acacias). While most wattles only live between 6 - 10 years, they are an important pioneer species which colonise disturbed areas, where other plants find it hard to grow. They improve soil conditions enough to allow other species to germinate and thrive by fixing nitrogen into the soil through their roots and adding high levels of organic leaf litter.
