Rhytida clarki
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Rhytida clarki faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in New Zealand. The species is particularly vulnerable to introduced predators such as rats and hedgehogs that consume both adults and eggs. Climate change poses additional risks through altered moisture regimes that affect the humid microhabitats essential for this terrestrial gastropod's survival.
Habitat
Rhytida clarki inhabits native forest floors and shrubland areas with high moisture levels and abundant leaf litter. The species requires specific microhabitat conditions including stable humidity, organic soil layers, and protection from direct sunlight.
