Quercus radiata is an endangered species of oak native to Mexico.

Description

[edit]

Quercus radiata is a small evergreen tree that typically reaches 4 to 9 metres (13 to 30 feet) in height.[1]

Distribution and habitat

[edit]

It is native to the southern Sierra Madre Occidental, including southern Durango, eastern Nayarit, western Zacatecas, and northern Jalisco. Its extent of occurrence is 13,000 square kilometres (5,000 square miles), with a low density within that range and an estimated area of occupancy between 64 and 375 km2 (25 and 145 sq mi).[1]

It is found on thin igneous soils and rocky outcrops between 2,000 and 2,600 m (6,600 and 8,500 ft) in elevation, where it form open stands with Pinus lumholtzii and other oaks and pines.[1][2]

Its range is mostly outside protected areas and subject habitat degradation from timber harvesting and encroachment by roads and agriculture.[1]
