Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Richardson's Least Gecko faces severe habitat loss due to urban development and tourism infrastructure expansion across its limited range in the Virgin Islands. The species' extremely small body size and specialized microhabitat requirements make it particularly vulnerable to habitat fragmentation, as even minor disturbances can eliminate suitable refugia. Introduced predators, including cats and rats, pose additional threats to this diminutive gecko, while climate change-induced sea level rise threatens coastal populations.

Threat summary

Habitat

Richardson's Least Gecko inhabits dry coastal forests, scrublands, and rocky areas with dense leaf litter and fallen logs that provide essential microhabitats. The species requires specific moisture and temperature conditions found under rocks, bark, and debris in these xeric environments.
