Echinodontium ryvardenii

Unknown

Overview

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

Echinodontium ryvardenii faces severe threats from deforestation and habitat fragmentation across its limited range in old-growth coniferous forests. The species' dependence on specific host trees and microhabitat conditions makes it particularly vulnerable to logging activities and forest management practices that alter forest structure. Climate change poses an additional threat by potentially shifting suitable habitat zones beyond the fungus's dispersal capabilities.

Threat summary

Habitat

This rare polypore fungus inhabits old-growth coniferous forests, typically growing as a wood-decay organism on dead or dying trees. It requires specific microhabitat conditions found in mature forest ecosystems with stable moisture levels and minimal disturbance.

Frequently asked questions

Why is Echinodontium ryvardenii classified as Endangered?
Echinodontium ryvardenii is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Echinodontium ryvardenii faces severe threats from deforestation and habitat fragmentation across its limited range in old-growth coniferous forests. The species' dependence on specific host trees and microhabitat conditions makes it particularly vulnerable to logging activities and forest management practices that alter forest structure. Climate change poses an additional threat by potentially shifting suitable habitat zones beyond the fungus's dispersal capabilities.
Where does Echinodontium ryvardenii live?
Echinodontium ryvardenii occurs in Italy. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Echinodontium ryvardenii?
The main threats to Echinodontium ryvardenii 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.
