Nesiergus halophilus

Unknown

Overview

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

Nesiergus halophilus faces severe threats from coastal development and sea-level rise, which directly impact its specialized salt marsh habitats. The species' extremely limited distribution makes it particularly vulnerable to habitat destruction, while pollution from agricultural runoff and urban development degrades the water quality essential for its survival. Climate change poses an additional threat through altered precipitation patterns that affect the salinity levels this halophilic species requires.

Threat summary

Habitat

Nesiergus halophilus inhabits specialized salt marsh environments and brackish coastal wetlands where it has adapted to high salinity conditions. The species is typically found in tidal zones and salt-tolerant vegetation communities along protected coastlines.

Frequently asked questions

Why is Nesiergus halophilus classified as Critically Endangered?
Nesiergus halophilus 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. Nesiergus halophilus faces severe threats from coastal development and sea-level rise, which directly impact its specialized salt marsh habitats. The species' extremely limited distribution makes it particularly vulnerable to habitat destruction, while pollution from agricultural runoff and urban development degrades the water quality essential for its survival. Climate change poses an additional threat through altered precipitation patterns that affect the salinity levels this halophilic species requires.
Where does Nesiergus halophilus live?
Nesiergus halophilus occurs in Seychelles. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Nesiergus halophilus?
The main threats to Nesiergus halophilus are 11.1, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
