Kauaʻi occurrence and status

Kauaʻi occurrence

Present

Origin

Introduced

Conservation status

Not assessed

Evidence limits

Occurrence is supported; local abundance and impact estimates remain less certain than presence.

Habitat and ecology

Habitats

Buildings, trees, bark and sheltered lowland structures.

Food and resource needs

Arthropods and other small invertebrates.

Reproduction

Species-appropriate egg-laying sites or live-bearing conditions; stable microclimate.

Shelter

Bark, foliage, rock, litter, crevices, walls, or woody debris depending on species.

Threats and conservation

Threats

Long-established introduced gecko; specific Kauaʻi ecological impact remains poorly quantified.

Conservation actions

Early detection, containment/control where feasible, prevent intentional release or transport, protect high-value native habitats, and monitor ecological effects.

Monitoring

Repeat island occurrence surveys, population trend monitoring, and impact studies using standardized methods.

Data gaps

Current population distribution, abundance, and Kauaʻi-specific ecological effect sizes remain incompletely quantified.

Process and seasonal context

Seasonal timing

Generally year-round in Hawaiʻi; local activity varies with temperature and moisture

Seasonal description

Stump-toed Gecko (Gehyra mutilata) is a documented established nonnative species on Kauaʻi.
