PictureCoast Live Oak

Generally found in well-developed canyons with a consistent water supply, these evergreen Oak trees are the cornerstone of Oak woodland habitats found throughout the Irvine Ranch Natural Landmarks. Their roots grow deep in order to tap into underground water sources, but their proximity to the coast allows them to take advantage of coastal fog as well. Their wide and dense canopy provides shade and habitat while their acorns provide a food source for many different animals that need healthy Oak woodland to survive. 

However, a recent influx of Gold Spotted Oak Borers has put the health of these Oak woodlands in danger. The Gold Spotted Oak Borer is a kind of beetle whose larvae feed below the protective bark layer of the tree, damaging the vital tissues needed to transmit water and nutrients throughout the plant. Extensive work is being done throughout the Landmarks to prevent the spread of this pest and recover lands already impacted. For more information please visit:

The health and protection of our Coast Live Oak population is essential to preserving the delicate balance of the many interconnected ecosystems that make up the Irvine Ranch Natural Landmarks.
