Overview

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

Quercus blaoensis faces severe population decline due to extensive deforestation and agricultural conversion throughout its limited range in Vietnam's mountainous regions. The species is particularly vulnerable to logging pressure as its high-quality timber makes it a target for commercial exploitation. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration capacity.

Threat summary

Habitat

This oak species is endemic to montane forests in northern Vietnam, typically occurring at elevations between 800-1,500 meters in mixed deciduous and semi-evergreen forest communities. It grows on well-drained soils along ridges and slopes in areas with high humidity and seasonal rainfall patterns.

Frequently asked questions

Why is Quercus blaoensis classified as Critically Endangered?
Quercus blaoensis 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 blaoensis faces severe population decline due to extensive deforestation and agricultural conversion throughout its limited range in Vietnam's mountainous regions. The species is particularly vulnerable to logging pressure as its high-quality timber makes it a target for commercial exploitation. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration capacity.
Where does Quercus blaoensis live?
Quercus blaoensis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Quercus blaoensis?
The main threats to Quercus blaoensis 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.
