- The Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) has issued this new publication.
- It has found that there are 37,000 alien species, including plants and animals, that have been introduced by many human activities to regions and biomes around the world.
- It is including more than 3,500 invasive alien species and that invasive alien species have played a key role in 60% of global plant and animal extinctions recorded.
- Invasive alien species are one of the five major direct drivers of biodiversity loss globally
- Not all alien species establish and spread with negative impacts on biodiversity, local ecosystems and species.
- About 6% of alien plants; 22% of alien invertebrates; 14% of alien vertebrates; and 11% of alien microbes are known to be invasive, posing major risks to nature and to people.
- At least 218 invasive alien species have been responsible for more than 1,200 local extinctions.
- 34% of the impacts of biological invasions were reported from the Americas, 31% from Europe and Central Asia, 25% from Asia and the Pacific and about 7% from Africa.
- Most negative impacts are reported on land (about 75%) with considerably fewer reported in freshwater (14%) and marine (10%) habitats.
- Most countries (80%) have included targets related to managing invasive alien species in their national biodiversity plans.
