Gulickia alexandri

Unknown

Overview

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

Gulickia alexandri faces severe threats from habitat destruction due to deforestation and agricultural expansion in its limited Hawaiian forest range. Invasive plant species alter the native understory composition that this endemic land snail depends on for shelter and food sources. Climate change poses additional risks through altered precipitation patterns that affect the moist microhabitats essential for this species' survival.

Threat summary

Habitat

This endemic Hawaiian land snail inhabits moist native forests, particularly in areas with dense leaf litter and native vegetation that provide the humid microhabitats necessary for its survival. It is typically found in undisturbed forest understory environments with high moisture retention and organic matter accumulation.
