Westraltrachia porcata
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Westraltrachia porcata faces significant pressure from habitat fragmentation and degradation across its limited range in southwestern Western Australia. Urban expansion and agricultural development have reduced and isolated suitable habitat patches, while altered fire regimes and invasive plant species further compromise the quality of remaining native vegetation. Climate change poses an additional threat through increased drought frequency and temperature extremes that affect the moisture-dependent microhabitats essential for this terrestrial gastropod's survival.
Habitat
This terrestrial snail inhabits native vegetation communities in southwestern Western Australia, particularly areas with dense leaf litter and fallen logs that provide essential moisture and shelter. It requires specific microhabitat conditions including adequate humidity levels and organic matter for feeding and reproduction.
