Description edit
It is a deciduous tree up to 15 metres (49 feet) tall with a trunk as much as 80 cm (31 in) in diameter. The leaves are thick and leathery, up to 11.6 cm (4+1⁄2 in) long, and elliptical with numerous pointed teeth along the edges.[3] It flowers from March to June, and its acorns mature between October and December.[1]
The species is known to hybridize with other sympatric red oak species across its range.[1]
Range and habitat edit
Quercus castanea is native to the mountains of Mexico, Guatemala, El Salvador, and Honduras. In Mexico, the species inhabits the Sierra Madre Oriental, Sierra Madre Occidental, Trans-Mexican Volcanic Belt, Sierra Madre de Oaxaca, and Sierra Madre del Sur between 1,400 and 2,600 meters elevation. It also inhabits the Sierra Madre de Chiapas of Mexico Mexico and Guatemala, and the Montecristo Massif where the borders of El Salvador, Guatemala, and Honduras meet. In Guatemala Q. castanea has been reported up to 3,500 meters elevation. The species' estimated extent of occurrence (EOO) is 1,110,000 km2, based on over 500 collections and herbarium records.[1]
The species is found in a variety of montane habitats. It is common in dry oak forests, xerophytic shrublands, and open oak woodlands alongside cacti and trees of family Leguminaceae. It also grows in humid montane cloud forests.[1]
In the Cuitzeo Basin of central Mexico, acorn woodpeckers (Melanerpes formicivorus) and golden-fronted woodpeckers (Melanerpes aurifrons) are important acorn dispersers.[1]
