Invasive alien species

The aliens have landed. They’ve taken up residence in our waterways, our cities, our farmland and forests. Their negative impacts to both the environment and the economy are enormous, and they aren’t going home any time soon. So what are ‘alien species’? In short, they are animals, plants or other organisms that we have introduced to areas outside of their natural range. They are considered to be ‘invasive’ when they become established, disperse and have negative impacts on people and / or wildlife.
