Ruatara oparica

Unknown

Overview

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

Ruatara oparica faces significant pressure from habitat degradation in its restricted range within New Zealand's North Island forests. Invasive plant species are altering the understory composition where this endemic land snail forages, while introduced mammals like rats and possums disturb the leaf litter microhabitats essential for its survival. Climate change poses an additional threat through altered moisture regimes that could affect the humid conditions this species requires.
