Heterocyclus perroquini

Unknown

Overview

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

Heterocyclus perroquini faces severe pressure from habitat destruction as Madagascar's remaining forest fragments continue to be cleared for agriculture and charcoal production. The species' limited distribution makes it particularly vulnerable to local extinctions, while invasive plant species alter the forest understory composition essential for this endemic snail's survival. Climate change compounds these pressures by shifting rainfall patterns that affect the humid microhabitats this species requires.

Threat summary

Habitat

This endemic Malagasy land snail inhabits the humid understory of Madagascar's eastern rainforests, typically found among leaf litter and decaying vegetation in areas with consistent moisture levels. The species requires intact forest canopy to maintain the cool, humid microclimate conditions essential for its survival.
