As fall sets in across southern California, dry weather, high temperatures, and Santa Ana winds increase the risk of wildfires on the Irvine Ranch Natural Landmarks. The recent Canyon Fire 2 spread across 9,000 acres of parks and open spaces in Orange County, but with the work of the Orange County Fire Authority and firefighters from across the state the fires have been 100% contained. Irvine Ranch Conservancy invites the community to continue to enjoy the open spaces by registering for fitness or interpretive programs, or help care for the lands by joining a stewardship activity or through the Orange County Fire Watch.
On October 9th 2017 a wildfire started near the intersection of the 91 freeway and 241 toll road and continued to spread through Anaheim Hills and East Orange reaching, reaching various parts of the Irvine Ranch Natural Landmarks and OC Parks. The coastal sage scrub and chaparral in the area, which dried out after the long summer months, left the plants and brush with very little moisture and contributed to the rapid movement of the fire. Though the fire has been contained, some parks and open spaces remain closed to the public.

Interior areas of Irvine Regional Parks have reopened and the OC Zoo is expected to reopen October 21, conditions permitting. At this time, Peters Canyon, Santiago Oaks, exterior portions of Irvine Regional Park and affected areas of Irvine Ranch Open Space remain closed. While portions of the Landmarks are currently closed, visitors are still encouraged to explore the great outdoors during the below programs. From stewardship programs like the It’s Harvest Time! At the Native Seed Farm, to fitness programs like the After Work Fitness Hike, and Wilderness Access Days, there are programs that cater to a variety of different skill levels and interests and encourage the community to continue to enjoy the lands.
