Overview

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

Quercus donnaiensis faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion in its native Vietnamese range. The species is further threatened by selective logging pressure targeting mature oak specimens for timber, while urban development continues to fragment remaining forest patches. Climate change compounds these pressures by altering precipitation patterns critical for oak regeneration in montane environments.

Threat summary

Habitat

This critically endangered oak species inhabits montane forests and woodland areas in Vietnam, typically occurring at elevations between 800-1,500 meters. It grows in mixed deciduous forests with well-drained soils and requires specific moisture conditions characteristic of Southeast Asian highland ecosystems.

Frequently asked questions

Why is Quercus donnaiensis classified as Critically Endangered?
Quercus donnaiensis 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. Quercus donnaiensis faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion in its native Vietnamese range. The species is further threatened by selective logging pressure targeting mature oak specimens for timber, while urban development continues to fragment remaining forest patches. Climate change compounds these pressures by altering precipitation patterns critical for oak regeneration in montane environments.
Where does Quercus donnaiensis live?
Quercus donnaiensis occurs in Vietnam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Quercus donnaiensis?
The main threats to Quercus donnaiensis are 5.3, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
