Robust Bracket

Fomitiporia robusta

Unknown

Overview

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

The Robust Bracket faces severe decline due to the loss of its specialized old-growth forest habitat, particularly ancient oak and beech woodlands that provide the large-diameter dead wood essential for its survival. Urban development, intensive forestry practices that remove dead wood, and the conversion of natural forests to plantations have dramatically reduced suitable substrate availability. Climate change compounds these pressures by altering forest composition and increasing the frequency of disturbances that fragment remaining populations.

Threat summary

Habitat

The Robust Bracket is restricted to mature and old-growth deciduous forests, particularly those dominated by oak and beech trees. It requires large-diameter dead wood and fallen logs in undisturbed forest environments with stable microclimatic conditions.
