Sculpin Snail

Stiobia nana

Unknown

Overview

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

Stiobia nana faces significant pressure from habitat degradation in its restricted montane forest range. The species' limited distribution makes it particularly vulnerable to localized disturbances, while ongoing deforestation and agricultural expansion continue to fragment its already small habitat patches. Climate change poses an additional threat by potentially shifting suitable temperature and moisture conditions beyond the species' adaptive capacity.

Threat summary

Habitat

Stiobia nana inhabits montane forest environments, typically found in humid, high-elevation woodland areas. The species appears to be restricted to specific microhabitat conditions within these montane ecosystems, contributing to its vulnerability.

Why is Sculpin Snail classified as Vulnerable?
Sculpin Snail is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Stiobia nana faces significant pressure from habitat degradation in its restricted montane forest range. The species' limited distribution makes it particularly vulnerable to localized disturbances, while ongoing deforestation and agricultural expansion continue to fragment its already small habitat patches. Climate change poses an additional threat by potentially shifting suitable temperature and moisture conditions beyond the species' adaptive capacity.
Where does Sculpin Snail live?
Sculpin Snail occurs in United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sculpin Snail?
The main threats to Sculpin Snail are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
