Invasive alien species (IAS) are a major threat to biodiversity and the way we live. Here you can find posters, animations and other resources for raising awareness about IAS. Please download them for use to inform and educate people about biological invasions. We have also included a manual to guide you in communicating about this important issue. Thank you for playing a part in increasing understanding of IAS.

You’re passionate about your aquarium & proud of your pond. They’re bursting with life: colourful fish, decorative crustaceans, fascinating molluscs and beautiful plants. Did you know that some of them could become invasive alien species? If they were to end up in our rivers, lakes, creeks and oceans – they could seriously harm the balance of nature & damage the economy.

You can help protect our precious nature: don’t release aquarium or pond species & responsibly dispose of unwanted plants & aquarium water.
Nature thanks you!

As an angler you are the eyes and ears of the waters. You enjoy the peace & quiet of nature. The time alone or the company of friends. And of course: the pure joy of catching a fish! Did you know that plants, fish and diseases are oen traveling with us from one waterway to another? They’re sticking to our clothes and fishing equipment. Some of these are invasive alien species that’ll seriously damage and block waterways, kill fish and spoil the joy of angling. And if the waterways aren’t healthy, neither are we.

You, as an angler, can help protect our precious waterlife: check, clean and dry your equipment, your nets and boots. Nature thanks you!

You love & enjoy your colourful garden. But did you know that secretly, parts of these tropical plants travel to the forest - sticking to our shoes, our tyres & our gear? And often … plant waste is being dumped in nature. No big deal, you might think. But some of these plants turn out to be invasive alien species: they overgrow or disturb the existing wildlife. The healthy ecosystem of the forest is gone, and so are the benefits for all of us.

You can help protect our precious forests by choosing your garden plants wisely & by disposing of your plant waste responsibly. The forest thanks you!

Did you know that we are regularly picking up hitchhikers? They travel invisibly from one place to another, sticking on our shoes and tyres, on our machines and working gear. They’re tiny animals or seeds and roots of plants, and they can end up in the forest. No big deal, you might think. But some of them are invasive alien species: they overgrow or disturb the existing wildlife. The healthy ecosystem disappears, and so do the benefits for all of us. Buildings and roads are damaged & trees get sick. This comes at a huge cost to nature and society.

You can help protect our precious forests by cleaning your shoes, your tyres & your gear before entering the forest. The forest thanks you!

This forest is packed with life. For millions of years plants, insects, birds, mammals and fungi have built a healthy ecosystem. But did you know that invasive alien species can travel with us secretly when we visit the forest - their seeds, roots & larvae are sticking to our shoes, our tyres & our gear. Once in the forest they overgrow, chase away or disturb the existing species. The healthy ecosystem of the forest is gone, and so are the benefits for all of us.

You can help protect our precious forests by cleaning your shoes, tyres and gear before & after your visit. The forest thanks you!

You’re passionate about your beloved pet. You’re proud to be taking care of such a great animal. Did you know that – if our pets end up in the wild, and if they survive – they can become invasive alien species? They then can seriously harm the balance of nature & damage the economy.

You as a responsible pet owner can help protect our precious nature: don’t release your pet in the wild. Nature thanks you!

You know what happens when soil is transported? Every little creature that lives in the soil - from plant seeds & roots to tiny animals - hitchhikes along and becomes part of the new environment. No big deal, you would say. But some plants, animals & microbes are invasive alien species. They overgrow or infest their new environment. The healthy ecosystem disappears. Buildings, roads, rivers, wildlife and crops are impacted. This comes at a huge cost to nature and to society.

Have you checked the soil you are about to move? Did you clean the soil from your boots, machinery & trucks in between jobs? The environment, your neighbours and your fellow taxpayers thank you!
