Quercus gambelii, or Gambel oak, is a deciduous small tree or large shrub found in the central southwestern United States and northwestern Mexico. Its range stretches from Utah to Texas and into parts of Mexico. Gambel oak thrives in rocky, alkaline soil at altitudes of 1,000-3,000 meters above sea level and can withstand precipitation ranging from 12 to 24 inches annually. Its leaves, which turn bright orange and yellow during autumn, are deeply lobed and glossy dark green on top and velvety underneath. The plant reproduces from acorns and root sprouts, leading to dense groves or thickets that often cover entire mountainsides. Due to its abundance, it is an important food source for browsing animals, and historically provided a reliable source of food for Native Americans. Gambel oak quickly re-establishes itself after fires due to its ability to resprout from root sprouts. Associated plant species include chokecherry, ponderosa pine, and serviceberry, while associated birds and mammals include Woodhouse's scrub jay, black-billed magpie, grouse, deer, chipmunks, and squirrels.
