Overview

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

Prostomis mandibularis faces severe population declines due to widespread loss of old-growth forest habitats across its range. The species' dependence on specific fungal associations in decaying wood makes it particularly vulnerable to intensive forestry practices and habitat fragmentation. Climate change further threatens the delicate moisture and temperature conditions required for its specialized ecological niche.

Threat summary

Habitat

Inhabits old-growth and mature coniferous and mixed forests, particularly those with abundant dead and decaying wood. The species requires specific moisture conditions and fungal associations found in undisturbed forest ecosystems with substantial coarse woody debris.
