Murina tenebrosa

Unknown

Overview

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

Murina tenebrosa faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited range in Southeast Asian montane forests. Mining activities and agricultural expansion have destroyed critical roosting sites in limestone caves and old-growth forest areas. The species' highly specialized habitat requirements and small population size make it extremely vulnerable to even minor environmental disturbances.

Threat summary

Habitat

This species inhabits primary montane forests at elevations between 1,000-2,000 meters, typically roosting in limestone caves and rock crevices. It forages in the forest canopy and understory of undisturbed tropical montane ecosystems.

Murina tenebrosa 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. Murina tenebrosa faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited range in Southeast Asian montane forests. Mining activities and agricultural expansion have destroyed critical roosting sites in limestone caves and old-growth forest areas. The species' highly specialized habitat requirements and small population size make it extremely vulnerable to even minor environmental disturbances.
Where does Murina tenebrosa live?
Murina tenebrosa occurs in Japan. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Murina tenebrosa?
The main threats to Murina tenebrosa 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.
