Succinea quadrasi

Unknown

Overview

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

Succinea quadrasi faces severe habitat degradation from urban expansion and agricultural conversion across its limited Philippine range. The species' dependence on specific moisture conditions in lowland areas makes it particularly vulnerable to drainage and land use changes. Coastal development and infrastructure projects have eliminated many historical populations, while remaining fragments face ongoing pressure from human encroachment.

Threat summary

Habitat
