Red-tailed Shiny Skink

Sigaloseps ruficauda

Declining

Overview

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

Sigaloseps ruficauda faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in New Caledonia. Mining activities, particularly nickel extraction, have degraded critical forest habitats where this endemic skink occurs. The species' extremely restricted distribution makes it highly vulnerable to any habitat modification, with invasive plant species further altering the understory structure of its native forest environment.

Threat summary
