Module 9 MITIGATION Module 9 Mitigation Learning Outcomes

Module 9 MITIGATION Module 9 – Mitigation

Learning Outcomes • Recognise some options to manage IAS impacts when managing IAS populations is not feasible Module 9 – Mitigation

Introduction • Sometimes not possible to prevent, eradicate or control IAS. • The only option is to then ‘live with’ the IAS and to lessen its impacts (mitigation) Module 9 – Mitigation

MITIGATION OPTIONS 1) Habitat manipulation 2) Supplementary feeding 3) Nest protection 4) Barriers 5) Translocation to “safe habitats”. Module 9 – Mitigation

Habitat Manipulation Making habitats less suitable for IAS, or more suitable for native species Module 9 – Mitigation

Supplementary Feeding Providing supplementary food exclusively to the impacted species Module 9 – Mitigation

Nest Protection Providing supplementary “nests” or protecting existing nests of impacted species Module 9 – Mitigation

Barriers Fences or barriers exclude or contain IAS from protected areas Module 9 – Mitigation

Module 9 – Mitigation

Translocation to “Safe” Habitats Module 9 – Mitigation

Summary Managing IAS populations is not always feasible or appropriate • “Impact mitigation” involves reducing the impacts of IAS on animals, plants and the environment • There are various options to manage IAS impacts • The most appropriate techniques will depend on the features of each site • Impact mitigation measures are seldom effective as a long-term solution Module 9 – Mitigation
