A term for Gambel's oak, which covers many Western mountainsides at elevations between 5,000 and 8,000 feet. The acorns from Gambel's oak are important forage for bears and deer, and the tips of the brush provide important winter browse for deer and elk. The brush typically grows in very close thickets, sometimes blanketing entire mountainsides, and typically grows ten or 15 feet tall and 8" at the butt, though in some instances it will grow to 35 feet and 16" or so at the butt.
