The Jurupa Oak, or Hurungna Oak,[1][2] 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,[3][4][5] making it one of the world's oldest living trees.[5] The oak was discovered by botanist Mitch Provance in the 1990s and at the time he recognized it as disjunct for the species and likely an “ancient” clonal stand.[6]

The colony only grows after wildfires, when its burned branches sprout new shoots.[3] 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.[3] The oak has roughly 70 clusters of stems in a thicket which measures 25x8 metres in area and one metre in height.[5]

The colony is located within a mile of 34°01′59″N 117°23′28″W / 34.033°N 117.391°W / 34.033; -117.391 at an elevation of approximately 1,312 ft (400 m) on a relatively steep north-facing slope.[5]

On September 5, 2024, the city council of Jurupa Valley, California, approved in a 3-2 vote a plan to build a mixed development on 1.4-square-miles that includes 1,700 homes and a light industrial park, within 550 feet of the Jurupa Oak.[7]
