Overview

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

Meta barreti faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks through altered cave microenvironments that could disrupt its specialized ecological requirements.

Threat summary

Habitat

Meta barreti inhabits cave systems and underground environments, typically found in limestone karst formations. The species requires specific microclimate conditions within these subterranean habitats, including stable temperature and humidity levels.
