The Jurupa Oak is a clonal colony of Quercus palmeri (Palmer's oak) trees in the Jurupa Mountains in Crestmore Heights, Riverside County, California. The colony has survived an estimated 13,000 years through clonal reproduction,[1][2][3] making it one of the world's oldest living trees.[3] The colony only grows after wildfires, when its burned branches sprout new shoots.[1] It is the only one of its species in the surrounding area, which is a much drier climate and lower altitude than that in which Palmer's oaks typically grow.[1] The oak has roughly 70 clusters of stems in a thicket which measures 25x8 metres in area and one metre in height.[3] The colony is located within a few miles of 34.033°N, 117.391°W at an elevation of approximately 1200 feet.[3] See also
