Palaina striolata

Unknown

Overview

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

Palaina striolata faces severe threats from habitat destruction as its limestone cave and karst forest environments are increasingly disturbed by quarrying activities and agricultural expansion. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while its specialized habitat requirements limit potential for natural recolonization. Climate change poses additional risks through altered precipitation patterns that could affect the humid microenvironments essential for this terrestrial gastropod's survival.

Threat summary

Habitat

This species inhabits limestone caves and associated karst forest environments, typically found in humid microhabitats within cave entrances and surrounding rocky outcrops. It requires stable moisture levels and specific calcium-rich substrates characteristic of tropical limestone formations.

Why is Palaina striolata classified as Critically Endangered?
Palaina striolata is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Palaina striolata faces severe threats from habitat destruction as its limestone cave and karst forest environments are increasingly disturbed by quarrying activities and agricultural expansion. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while its specialized habitat requirements limit potential for natural recolonization. Climate change poses additional risks through altered precipitation patterns that could affect the humid microenvironments essential for this terrestrial gastropod's survival.
Where does Palaina striolata live?
Palaina striolata occurs in Palau. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Palaina striolata?
The main threats to Palaina striolata are 2.1, 8.1, 9.4, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
