Mainstreaming Invasive Alien Species: Prevention, Control and Management

Mauritius is part of the World's biodiversity hotspots. With the arrival of human settlers in the 17th century, natural habitats were exploited and Invasive Alien Species (IAS) were introduced. These non-native plants, animals, pathogens and organisms have quickly spread across the country's terrestrial and marine ecosystems, hence threatening the native biodiversity, economy and human health. 

Through a USD 3.8 million grant, the Global Environment Facility (GEF) will support the Government of Mauritius to:

  • build capacity for effective prevention, control and management of IAS
  • strengthen legislative, policy and institutional framework
  • improve knowledge and increase awareness on the risks posed by IAS and the need for biosecurity

This project will help the country review and update the National Invasive Alien Species Strategy and Action Plan (2023-2030).
