O'Neill Regional Park's 4,500 acres are situated in beautiful Trabuco and Live Oak Canyons. The park is heavily wooded with coast live oak and sycamore trees. The hillsides surrounding the park are filled with cactus, wild buckwheat, sagebrush and chaparral of scrub oak, buckthorn and mountain mahogany. Trabuco and Hickey Creeks also meander through the park, flowing in winter and early spring, dry in summer and fall.

Invasive Pest Found in Orange County

Gold Spotted Oak Borer (GSOB), an invasive beetle that has killed thousands of oak trees in San Diego and Riverside counties in a short span of time, has now been detected in Orange County. The GSOB was discovered in approximately 60 trees on County park land in northern Orange County. Since GSOB is transported in oak firewood, it is critical that Californians keep firewood local and not move it out of the area.
