Quercus ithaburensis | Davis

Among the rare Mediterranean oaks that grow at the Shields Oak Grove in Davis, CA, are several Tabor Oaks, the type of Quercus ithaburensis which can be found in the Levantine countries of the eastern Mediterranean. Tabor Oak is known for its striking and graceful growth habit, clearly visible in this pair of trees more than half a century in age. This photo shows with remarkable clarity the role of woodland competition in creating tree canopy shape. These trees are likely siblings, from the same mother tree, based on a range of morphological comparisons. One sibling grew more rapidly than the other, and is now in the inexorably slow process of engulfing the other.
