8:30 AMSahara Mustard Pull at Loma Ridge
  • Sahara mustard is a nasty exotic that has invaded thousands of acres across Southern California and is just beginning to encroach upon the Irvine Ranch Natural Landmarks. Now is the time to act! Over the last five years volunteers have been successfully keeping this plant at bay at Loma Ridge within the Irvine Ranch Open Space. Your help is needed to search for and remove new mustard plants that have come up from seed so that we can keep this weed from infesting our wild lands! This event will include bending, kneeling and walking across slopes and uneven terrain. All training and tools will be provided. We hope you can join us!

April 6, 2018  Closed Portion of Santa Ana River Trail to Reopen April 7

A portion of the Santa Ana River Trail from Memory Lane in Santa Ana to Taft Avenue in Orange was closed on January 22, 2018, to the public for an environmental remediation project. It was anticipated to remain closed for up to three months.

The County has made significant progress on the project, and a modified public access route will be restored April 7, 2018.

While environmental remediation work is ongoing in some areas, the work zones will be secured by temporary construction fencing. A slightly modified trail route will allow public use of a trail for hiking, bicycling, and equestrian activity only while being separated from continuing project and maintenance activities.
