Brief project description: The objective of the project is to safeguard globally significant biodiversity in vulnerable ecosystems through the prevention, control, and management of invasive alien species (IAS) in the Republic of Mauritius. The Project identifies three impact pathways to achieve this objective:1. Creating the policy and institutional frameworks needed for effective prevention, control and management of IAS to secure ecosystem goods and services under pressure from IAS. It builds the right enabling environments (policies, institutional coordination) for mainstreaming IAS prevention, control, and management. 2. Establishing a multi-tier strategy for effective tackling of IAS - The strategy includes improved preventative measures at points of entry into the country and inter-Islands, early detection and rapid response programmes to eradicate new incursions. It also includes improved capacity to upscale proven methodologies for managing IAS on a landscape level. 3. Up-to-date information for raising public awareness and enhancing understanding of the centrality of IAS programmes for protecting biodiversity, ecosystems, the economy, and livelihoods. It ensures that knowledge management supports monitoring, assessment and learning and forms the basis for adaptive project implementation, achievement of results, impacts, and upscaling of experiences in the Republic of Mauritius and in the region. This will ensure that the interventions of the project inform and influence the behaviours of a wider IAS constituency.
