Two previous articles of Naturally Riverside featured the Jurupa Oak, California's oldest tree. At least 13,000 years old, the Jurupa Oak (sometimes known as the "Hurunga Oak") coexisted with saber-toothed cats and mastodons. It ranks among the top oldest living organisms in the world. Over the past few years, the Jurupa Oak's fate has been uncertain. A legal agreement has now made its fate secure.
How did we get here? The July 2024 article described the oak and the scientific data demonstrating its advance age. Also, it explained the oak's adaptation for long-term growth, namely, withstanding fires by resprouting into a clonal shrub of hundreds of stems in a hillside blanket nearly 80 feet long. At that time, the Jurupa Valley Planning Commission had just considered the Jurupa Valley Rio Vista Specific Plan, a plan to allow more than 900 acres of residential and industrial development in the vicinity of the oak. The Jurupa Oak was the acknowledged elephant in the room. So the Commission delayed voting, asking for more detailed studies to determine how the tree gets its water, how conservation organizations would manage and protect the tree, and what size buffer area would reduce potential problems.
An October 2024 article updated the situation. In August 2024, the Commission approved the Plan. On Sept. 6, 2024, the Jurupa Valley City Council voted 3 to 2 to approve it with a 450-foot buffer around the plant. The complete final Environmental Impact Report was not made publicly available. Environmental groups were disappointed, citing the buffer distance as inadequate.
On Oct. 4, 2024, four conservation groups sued the city of Jurupa Valley's approval of the plan: Friends of Riverside's Hills, the Center for Biological Diversity, the California Native Plants Society, and Endangered Habitats League. The focus of those groups ranged from the local to the state to the national. The suit alleged that the environmental review violates the California Environmental Quality Act. Specifically, the lawsuit questioned whether the impacts of development might be harmful to the Jurupa Oak as well as other potential environmental impacts to the immediate region. The goal of the lawsuit was not to stop development altogether but to include a 100 acre preserve.
On May 12, the conservation groups and the developer reached an agreement to create a protected area and wildlife corridor to ensure protection for the oak and its associated natural community. Specifically, it expands the buffer around the oak to 1,000 feet and protects 54.7 acres of open space. The agreement also allows environmental groups or California Native American Tribes to purchase another 54.3 acres to protect even more space. As part of the agreement, the plaintiffs withdrew their suit.
Environmental news is often filled with doom and gloom. Let's celebrate the opportunity for the Jurupa Oak to live even more millennia. Who knows what it will witness in its next ten thousand years?
