Objective 3.7 - Invasive alien species (IAS) and pathways are identified and prioritized, priority species are controlled or eradicated, and measures are in place to manage pathways to prevent their introduction and establishment.
Biological invasions are the second most important cause of the extinction of species worldwide (and in Belgium) after the loss of natural habitats. Organisms can be introduced beyond their natural range, either intentionally or unintentionally. Those include disease-causing viruses, bacteria, fungi, algae, mosses, ferns, flowering plants, invertebrates and vertebrates. When invasive, they can cause environmental damage and can have a detrimental impact on health, the economy and safety.
