High-risk invasive-species arrival & reintroduction

Names and classification

Record type

threat

Kauaʻi occurrence and status

Recorded state

Continuing arrival risk

Threats and conservation

Pressure source

Transport pathways carrying mongoose, coqui, brown tree snake, pests, pathogens or other high-impact organisms

Exposure pathway

Hitchhiking via cargo, plants, vehicles, vessels, aircraft and inter-island movement

Consequences

New predation, disease, competition, crop damage or ecological transformation

Affected requirements

Island biosecurity and ecosystems currently free of particular high-impact pests

Susceptibility

Islandwide biodiversity, agriculture and public health depending on invader

Reversibility

Highly reversible before establishment; sharply less reversible after widespread establishment

Early warning indicators

Port/interception records; credible reports; sentinel/trap detections; pathway failures

Conservation interventions

Implementation limits

Magnitude, exposure and trend are not assumed uniform across Kauaʻi; local evidence governs.
