Overview

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

Stemonurus apicalis faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion and logging activities across its limited range. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction, with remaining populations increasingly fragmented and isolated. Mining operations and infrastructure development have further reduced available habitat, while the species' specific ecological requirements limit its ability to adapt to degraded environments.

Threat summary

Habitat

Stemonurus apicalis inhabits primary and secondary tropical rainforests, typically found in the understory and mid-canopy layers of lowland and hill forests. The species shows preference for areas with dense canopy cover and high humidity levels, occurring at elevations up to 800 meters in undisturbed forest ecosystems.

Frequently asked questions

Why is Stemonurus apicalis classified as Critically Endangered?
Stemonurus apicalis 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. Stemonurus apicalis faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion and logging activities across its limited range. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction, with remaining populations increasingly fragmented and isolated. Mining operations and infrastructure development have further reduced available habitat, while the species' specific ecological requirements limit its ability to adapt to degraded environments.
Where does Stemonurus apicalis live?
Stemonurus apicalis occurs in Sri Lanka. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Stemonurus apicalis?
The main threats to Stemonurus apicalis 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.
