Quercus mulleri

Unknown

Overview

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

Quercus mulleri faces severe population decline due to habitat conversion for agricultural development and urban expansion across its limited range in Mexico. The species is particularly vulnerable to drought stress and changing precipitation patterns, which affect its ability to regenerate successfully. Overgrazing by livestock has degraded understory conditions and prevented seedling establishment, while fire suppression has altered natural regeneration cycles that this oak species historically depended upon.

Threat summary

Habitat

Quercus mulleri inhabits montane oak forests and pine-oak woodlands at elevations between 1,500-2,800 meters in the Sierra Madre Oriental of Mexico. The species typically grows on well-drained slopes and ridges in mixed forest communities with other oak species and conifers.

Frequently asked questions

Why is Quercus mulleri classified as Critically Endangered?
Quercus mulleri 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 mulleri faces severe population decline due to habitat conversion for agricultural development and urban expansion across its limited range in Mexico. The species is particularly vulnerable to drought stress and changing precipitation patterns, which affect its ability to regenerate successfully. Overgrazing by livestock has degraded understory conditions and prevented seedling establishment, while fire suppression has altered natural regeneration cycles that this oak species historically depended upon.
Where does Quercus mulleri live?
Quercus mulleri occurs in Mexico. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
