Environmental Weeds Fact Sheets

Environmental Weeds

What are they?

There are many plants which could be classed as environmental weeds or pest plants.

Some ornamental plants, grown in home gardens, may be considered a threat. They may threaten human health, native bushland and natural resources such as waterways, creeks and rivers.

They are often hard to eradicate, spread rapidly and some have toxic or harmful properties.

They can become a serious weed problem if prunings, clippings and unwanted plants are discarded onto vacant land or dumped into natural bushland.

What can you do?

The responsibility for the control of these plants lies with everyone. Common sense and good gardening practices help with their control.

All unwanted plant refuse should be mulched, composted or taken to designated council disposal areas.

This helps reduce the chance of garden escapes.
