4PLANET IMPACT / ISSUE
Invasive alien species and disease
Introduced species and pathogens can disrupt native communities, ecosystem functions and livelihoods.
Why it matters
Impacts depend on the species, pathway, ecosystem and geography, so invasion status cannot be inferred from presence alone.
What the sources establish
IPBES finds invasive alien species are a major direct driver of biodiversity loss and ecosystem change, with impacts varying by species and place.

Organisations
Known and not established
- Occurrence records require taxonomic confidence and do not by themselves establish ecological impact.
- This issue record is source-grounded context, not proof that any particular project, action or intervention is effective.

Truth boundary. Listing does not imply 4PLANET partnership or endorsement. Source-reported figures are not independently verified by 4PLANET. Delivery, outcome and verification remain separate states.
Approaches associated with this problem
- Island invasive-species and seabird restoration — Restore island ecosystems through invasive mammal eradication, native vegetation recovery, seabird recolonisation methods and biosecurity.
- Invasive-plant removal and native-forest rewilding — Remove invasive vegetation, establish locally sourced native trees and monitor recovery in degraded forest remnants.
