“Nearly all of OC Parks’ Limestone Canyon Nature Preserve burned in the 2020 Silverado and Bond fires, including large portions that actually burned twice. These incidents significantly impacted the wildlife and landscapes that are close to the hearts of so many who visit and volunteer at Limestone Canyon,” said OC Parks Supervising Park Ranger II Nick Martinico. “We observed this closure to allow a rest period for wildlife, time for habitat regrowth and to rebuild infrastructure. We deeply appreciate the public’s patience and support and are now eager to once again host activities at Limestone Canyon starting with our Wilderness Access Day in February.”

“Limestone Canyon is home to important, high-quality habitats including oak woodlands that wildlife in the area rely on for food and shelter,” said IRC Vice President and Chief Programs Officer Nathan Gregory. “Our team worked closely with OC Parks Rangers to monitor conditions throughout Limestone Canyon during the closure. Unfortunately, the lack of rain this past year meant continued stressful conditions for wildlife and slower vegetation regrowth. However, we now feel that the situation has sufficiently improved to handle the impacts of public activities, and we are excited to host the community out on the land once again.”
On Saturday, February 5 from 8 a.m. - 2 p.m., IRC and OC Parks invites nature lovers to celebrate the reopening of Limestone Canyon during the first Wilderness Access Day in the area since 2020. To register for Wilderness Access Day in Limestone Canyon, visit LetsGoOutside.org.
