Overview

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

Thesbia nana faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' small body size and specialized ecological requirements make it particularly vulnerable to habitat fragmentation, while invasive plant species alter the microhabitat conditions essential for its survival.

Threat summary

Habitat

Thesbia nana inhabits specialized microhabitats within tropical and subtropical dry forests, typically found in leaf litter and low vegetation layers. The species requires specific moisture and temperature conditions found in undisturbed forest understory environments.

Frequently asked questions

Why is Thesbia nana classified as Endangered?
Thesbia nana 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. Thesbia nana faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' small body size and specialized ecological requirements make it particularly vulnerable to habitat fragmentation, while invasive plant species alter the microhabitat conditions essential for its survival.
Where does Thesbia nana live?
Thesbia nana occurs in Canada, Faroe Islands, Iceland, Italy, Norway, and Svalbard & Jan Mayen (plus 3 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Thesbia nana?
The main threats to Thesbia nana 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.
