Irvine Regional Park is nestled among groves of Oak and Sycamore trees, and offers visitors a wide variety of shaded areas, serene leisure activities, and is home to the OC Zoo. Rolling foothills surround the park and are home to a variety of wildlife, which greatly enhances the park’s beauty. To keep the park thriving and flourishing, monthly stewardship activities are held at Irvine Regional Park to keeps the trails and habitat healthy.
“As the weather gets warmer we encourage visitors to not only get outside and enjoy the Landmarks, but to consider registering for a stewardship program to connect with the land,” Irvine Ranch Conservancy Deputy Director, Dave Raetz said. “Irvine Regional Park is a highly attended park with a great amount of visitorship, and it’s really wonderful that this program offers nature lovers a chance to give back to the land.”

Volunteers will also remove invasive plant species that threaten to crowd out the diversity of native plants, a vital part of restoration programs. An invasive plant can thrive and spread aggressively outside its natural range and can be especially invasive when introduced to a new habitat. When an invasive species colonizes a new area, it may gain an ecological edge since the insects, diseases, and foraging animals that naturally keep its growth in check in its native range are not present in the new habitat. It’s important to remove invasive plants so they don’t threaten native plant life or reduce the natural biodiversity. Volunteers who participate in the Irvine Park Trail Restoration Day will have the opportunity to enjoy the great outdoors and help plant native species while removing invasive species.
Several stewardship and restoration programs are offered on the Irvine Ranch Natural Landmarks throughout the year to help promote the growth of native species in the wide variety of landscapes within Orange County.
