Trochomorpha apia

Unknown

Overview

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

Trochomorpha apia faces severe habitat degradation from urban development and agricultural expansion across its limited range in Samoa. The species is particularly vulnerable to introduced predatory species and habitat modification that alters the forest floor microenvironments essential for its survival. Climate change poses additional risks through altered precipitation patterns that could affect the moist conditions this terrestrial gastropod requires.
