Dune restoration & native coastal vegetation

Names and classification

Record type

intervention

Kauaʻi occurrence and status

Recorded state

Available, active, proposed or context-dependent

Conservation interventions

Action definition

Restore dune sand storage, native vegetation and coastal resilience

Mechanism of action

Manage access, remove unsuitable invasive vegetation, establish native dune plants and restore dune morphology where appropriate

Prerequisites

Sediment/site assessment; compatible native plants; access planning; permits

Implementation context

Degraded sandy beaches/dunes with adequate migration space

Expected outcomes

Larger/stabler dune reservoir, more native vegetation and reduced trampling

Monitoring design

Dune volume/elevation; native cover; access scars; shoreline/beach width

Unintended consequences

Over-stabilization or inappropriate planting can interfere with natural sand movement

Implementation limits

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