Quercus martinezii

Quercus martinezii is a species of oak found in southwestern and central Mexico. It has been found in Nayarit, Jalisco, Michoacán, Guerrero, and Oaxaca states.[2][3][1][4] It is placed in Quercus section Quercus.[5]

Description

[edit]

It is a tall forest tree up to 25 metres (82 feet) tall with a trunk 50 centimetres (20 inches) or more in diameter. The leaves are thick and stiff, gray-green on the upper surface, lighter on the underside, lance-shaped or egg-shaped with irregular teeth.[3]

Range and habitat

[edit]

Quercus martinezii is native to montane forests in the mountains of west-central and southern Mexico. It is found in the Sierra de San Juan of western Nayarit, the western Trans-Mexican Volcanic Belt of Jalisco, Michoacán, and Mexico states, and the Sierra Madre del Sur of Michoacán, Guerrero, and Oaxaca states.[1]

The tree is generally found in cloud forests, and occasionally in humid oak forest and pine–oak forests, between 1,800 and 2,600 meters elevation.[1]

Conservation and threats

[edit]

The population size and trends of Quercus martinezii have not been quantitatively studied. Its observed populations are generally low-density or scarce. It is threatened with habitat loss from deforestation across much of its range.[1] There are populations in several protected areas, including the Sierra de San Juan Biosphere Reserve in Nayarit, the Sierra de Manantlán Biosphere Reserve in Jalisco.
