Description
editQuercus hirtifolia is a large shrub or small tree, growing up to 7 meters, and rarely to 9 meters, in height.[1]
Range and habitat
editQuercus hirtifolia is native to the Sierra Madre Oriental, where it is found in small allopatric populations between 1600 and 2450 meters elevation. It inhabits humid oak-pine forests, cloud forests, and conifer forests.[1]
Its geographic range is small, with an estimated area of occupancy (AOO) of 128 km2 and an extent of occurrence (EOO) of 3,700 km2.[1]
Conservation and threats
editThe species has a limited range, and its habitat is declining in area, extent, and quality. Its conservation status is Endangered.[1]
The principal threats are deforestation of its native habitat for conversion to livestock pasture and agriculture. It also faces threats from illegal logging. Climate change is expected to reduce cloud forest habitat in the Sierra Madre Oriental but about 45% by 2080, which would further reduce suitable habitat for the tree.[1]
