Sahara 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!
