Invasive Species: What You Can Do

1. Check the plants you are buying for your garden are not invasive

If possible, replace invasive plants in your garden with non-invasive alternatives. Ask your local nursery staff for help in identifying invasive plants.

For example: Although pretty, the Lantana plant forms dense, impenetrable thickets that take over native bushland and pastures on the east coast of Australia. It impacts 95 threatened plants species in Australia*.

2. When boating, clean your boat thoroughly 

Remove all visible mud, plants, fish/animals from your boat, trailer, clothing, dogs, fishing gear or other equipment and dispose of in a suitable rubbish container or on dry land. This is to prevent inadvertantly transporting nasties to a different body of water.

Drain all water from boat, hatches, bilge, live wells, transom wells and any other locations with water on land before leaving the launch site. Remove the drain plug before towing to allow the boat to drain completely.

Never dump live fish or other organisms from one water body into another.

3. Clean your clothes, boots and gear 

Do this after each hike to get rid of hitchhiking weed seeds and pathogens. Pick off seeds from shoes and clothes, and check your gear to make sure seeds are not hiding in pockets or on Velcro straps

Keep to designated tracks to avoid spreading diseases into untracked areas, especially on wet ground. 

Chytrid is a fungal disease blamed for frog extinctions both here in Australia and overseas. Phytophthora is a root rot that destroys native plants. It's spread in mud and soil on walkers’ boots, bikes and vehicles.

4. Don't "pack a pest" when traveling

Fruits and vegetables, plants, insects and animals can carry pests or become invasive themselves. Take extra care when moving across state borders.

Don't move firewood. They can harbour pests. Firewood that comes from healthy trees or that has been properly aged and seasoned can still attract invasive species when stored outdoors. The small eggs and larvae of invasive species are difficult to detect. They can hide or lay dormant on or under the bark, or inside the wood itself, escaping detection. If that untreated and raw firewood is moved, the invasive species can spread into new areas.

5. Don't release aquarium fish and plants into the wild

This includes live bait or other exotic animals. If you plan to own an exotic pet, do your research and plan ahead to make sure you can commit to looking after it.

It's not just large fish that can cause havoc. Small ornamental fish species popular in aquariums can be just as great a threat to native fish species.
