Bear Oak (Quercus ilicifolia) vs. Black Oak (Quercus velutina)

Updated October 1st, 2020

These species are easily confused. Black oak has a much broader range of habitat preferences, but can overlap with bear oak both in dry, sandy coastal areas and more barren upland sites, and when it does, it tends to exhibit morphological changes that make it look more similar. The species are easily distinguished by differences in leaf shape, pubescence on leaves and buds, and growth habit. Acorns are similar but can be distinguished by how much of the nut the cap covers, and whether or not the scales of the cap are loose.
