Predator-exclusion fencing

Names and classification

Record type

intervention

Kauaʻi occurrence and status

Recorded state

Available, active, proposed or context-dependent

Conservation interventions

Action definition

Create protected breeding habitat inaccessible to invasive mammalian predators

Mechanism of action

Fine-mesh predator-resistant barriers plus removal and biosecurity inside enclosure

Prerequisites

Suitable terrain; complete enclosure; predator removal; intensive fence maintenance

Implementation context

Seabird colonies, sensitive nesting areas and other feasible protected sites

Expected outcomes

Higher nesting survival and protected breeding habitat

Monitoring design

Fence breaches; predator detections; nesting success; recruitment; enclosure occupancy

Unintended consequences

Fence failure can create high-risk false security; may constrain access or non-target movement

Implementation limits

Implementation status, cost and efficacy must be tied to a dated place/program record.
