Distribution and habitat
Quercus castanea is native to the mountains of Mexico, Guatemala, El Salvador, and Honduras.[3][4][2] 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 m (4,600 and 8,500 ft) 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 m (11,500 ft) elevation. The species' estimated extent of occurrence is 1,110,000 square kilometres (430,000 sq mi), based on over 500 collections and herbarium records.[2]
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.[2]
In the Cuitzeo Basin of central Mexico, acorn woodpeckers (Melanerpes formicivorus) and golden-fronted woodpeckers (Melanerpes aurifrons) are important acorn dispersers.[2]
