Restoration in Big Canyon

Stewardship
Stewardship

Around 25,000 plants have been installed at our Big Canyon restoration site, and we would love your help protecting the new plantings from invasive plants. Invasive plants pose a huge threat to displacing native plant communities and wildlife at the Bay, second only to habitat loss. By removing invasive weeds, we will ensure the Big Canyon project site thrives with native plants for years to come. No prior plant ID/weeding experience necessary.

Minors must have a legal guardian present at all times.

To register, go to: RestoreBigCanyon.eventbrite.com

Interested in bringing out a large group of 15 or more? Please contact Zachery Flores at zachery.flores@newportbay.org for more information on how to sign up.

Time & Location
We will meet at 9am at the project site entrance. A map with directions will be included in your confirmation email following registration. From the parking location, the project site is a short 5-minute walk into the canyon. NOTE: There are no restrooms at this location.

What to Bring/Wear
Be sure to bring sunscreen, a hat, and plenty of water. We also recommend wearing breathable clothing that you don’t mind getting dirty. Hand tools, shovels, and gloves will be provided. All volunteers not yet fully vaccinated must wear a face mask while on the project site. Face masks are optional for fully vaccinated volunteers.

Early Morning Fitness Hike on Hicks Haul Road: 6-miles

Join us for an exhilarating morning fitness hike on the paved Hicks Haul Road in OCParks’ Irvine Ranch Open Space. This hike is a 6-mile route as a group – which is conducted at the speed of about 3.0 to 3.5 miles per hour. The footing on the asphalt paved road is smoother than dirt roads and single-track trails normally found in Limestone Canyon Nature Preserve but is beginning to show its age with cracks, crevices, and an occasional dip. Otherwise, the terrain is smooth, so this is a great hike for anyone who wants a “wilderness experience” without getting dirty! We will have two fairly steep ascents and descents. Along the way, you will have sweeping views of much of Orange County and the Santa Ana Mountains. Various animals, like hawks, deer, and lizards are also frequently seen in this area.
