Tomichia ventricosa

Unknown

Overview

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

Tomichia ventricosa faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in South Africa's Western Cape. The species' restriction to specific soil types and vegetation communities makes it particularly vulnerable to land conversion, while invasive plant species alter the delicate ecological balance of its native habitat. Climate change poses an additional threat through altered precipitation patterns that could affect the moisture-dependent environments this gastropod requires.

Threat summary

Habitat

This endemic South African land snail inhabits the fynbos vegetation of the Western Cape, specifically occurring in areas with particular soil compositions and moisture regimes. The species is restricted to small, fragmented patches of natural vegetation within an increasingly developed landscape.

Frequently asked questions

Why is Tomichia ventricosa classified as Endangered?
Tomichia ventricosa is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Tomichia ventricosa faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in South Africa's Western Cape. The species' restriction to specific soil types and vegetation communities makes it particularly vulnerable to land conversion, while invasive plant species alter the delicate ecological balance of its native habitat. Climate change poses an additional threat through altered precipitation patterns that could affect the moisture-dependent environments this gastropod requires.
Where does Tomichia ventricosa live?
Tomichia ventricosa occurs in South Africa. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Tomichia ventricosa?
The main threats to Tomichia ventricosa 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.
