Case study: Managing Invasive Alien Species in Africa

Invasive alien species (IAS) are a major, accelerating driver of biodiversity loss and ecosystem degradation across Africa, with growing implications for water security, food systems and rural livelihoods. The IUCN Save Our Species (SOS) African Wildlife Initiative (SOS AWI)—funded by the European Union—supports locally led, science-based action to reduce key biodiversity threats, including IAS, through practical management, restoration and capacity strengthening.
This case study document synthesises four AWI-supported interventions that illustrate “field-tested” IAS responses spanning terrestrial and freshwater ecosystems in South Africa and Cameroon. Collectively, these interventions combine mechanical removal, fire-based control, regulated biological control, ecological restoration, and community engagement to restore habitat condition, reduce invasive pressure on threatened species, and build local stewardship and technical capacity.
