Common names

Brown Anole

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

Lowland vegetation, trunks, fences, gardens and developed landscapes.

Food and resource needs

Primarily arthropods; opportunistic small prey.

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

Potential competition with other lizards and predation on native arthropods; Kauaʻi-specific impact magnitude is not well 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

Brown Anole (Anolis sagrei) is a documented established nonnative species on Kauaʻi.
