[wikipedia] Distribution, Ecology: Distribution Quercus turbinella has been found in Arizona, New Mexico, Colorado, Utah, Nevada, southern California, and western Texas, as well as Baja California.[7][4] In California, it occurs in the New York mountains and a few eastern California desert ranges. The populations on the desert mountains in the western Mojave desert and the inner coastal ranges are now considered Quercus john-tuckeri.[8][9] It grows in woodland, chaparral, forest, and other habitat. It is most common in chaparral habitat in central Arizona,[5] through the transition zone of the Mogollon Rim White Mountains, but also southeast Arizona in the Madrean Sky Island mountain ranges of sky islands.[10] Ecology Quercus turbinella easily hybridizes with other oak species, including Quercus gambelii, Q. havardii, Q. arizonica, and Q. grisea.[5] Many species of animals use it for food, with wild and domesticated ungulates browsing the foliage and many birds and mammals eating the acorns.[5] Animals also use the shrub as cover, and mountain lions hide their kills in the thickets.[5] (contributed by Mary Ann Machi)
