Whether you need volunteer service hours or just love the Bay, join us to give back and help protect and preserve one of Orange County’s greatest natural resources.

Minors aged 16 and younger must have legal guardian present at all times.

Invasive Removal:

Below Irvine Lake, Santiago Creek is joined by Fremont Creek before flowing, often unseen, down a broad wash into Irvine Regional Park and beyond. Much work has been done over several years to eliminate the many invasive plants in this unique area. Join a motivated group that will sweep through the diverse landscape targeting a few clusters of fountain grass and castor bean that have re-sprouted while keeping an eye out for isolated plants that have been missed. The recent rains will make the work easier and we will enjoy walking through a great diversity of native plants greening up and flowering after the rain and fire as well as spotting the occasional fossil. We will try to move at a quick pace, but the route will cover irregular terrain with lots of river rock, sand and occasional muddy spots requiring careful walking. Tools, gloves, snake chaps and water are provided. Good, closed toe shoes or boots are required. We will begin and end at Lot 15 of Irvine Regional Park.

Sahara mustard is a plant that threatens to take over native habitat and has invaded thousands of acres across Southern California. This new invasive mustard has encroached upon the Irvine Ranch Natural Landmarks. This season is the perfect time for you to act and join us out on the land!

Over the last six years volunteers have been successfully keeping this plant at bay 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 wildlands! This event may include bending, kneeling, and walking across slopes and uneven terrain. All the information you will need and tools will be provided. If you have your own sturdy gardening gloves, please bring them. We hope you can join us!
