Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Oak Woodwax faces severe population declines due to widespread destruction and fragmentation of its specialized old-growth forest habitats. Climate change is altering the delicate moisture and temperature conditions this mycorrhizal species requires, while pollution and habitat degradation further compromise the health of its host oak trees and forest ecosystems.
Key Facts
Habitat & Distribution
Mature deciduous and mixed forests dominated by oak species, particularly in moist, well-drained soils of old-growth woodlands. Forms essential mycorrhizal associations with oak roots in undisturbed forest ecosystems across temperate regions.
