New Restoration Project Will Help Maintain Oak Woodlands in Limestone Canyon

2/6/2020

 
PictureOaks in Limestone Canyon
Since 2005, Irvine Ranch Conservancy has made it their mission to preserve and restore natural habitats found throughout the Irvine Ranch Natural Landmarks. With their newest restoration project, Irvine Ranch Conservancy staff and volunteers will plant 500 acorn seedlings at the Augustine Staging Area Nursery in Limestone Canyon that will be used to maintain vital oak woodland habitats.
 
The acorns collected by the Conservancy are sourced locally from oak trees throughout the area, giving them a greater chance of success due to acclimation to local climate and soil. After the acorns are collected, they will then be planted at the Augustine Nursery, where staff and volunteers will assist in tending and growing the acorns to seedlings until they are ready for planting. Restoration projects such as this allow Irvine Ranch Conservancy to expand its work of restoring habitats that support local wildlife and plant species.

Landmark Focus: Limestone Canyon Nature Preserve

Picture'The Sinks' at Limestone Canyon
​One of the most iconic locations within the Irvine Ranch Natural Landmarks, Limestone Canyon never ceases to amaze.  Located between the rugged Santa Ana Mountains and central Orange County, Limestone Canyon is home to a variety of plants, animals, and unique geological features.  Its oak filled valleys and year-round springs made it a popular place for Native Americans and early European settlers to hunt and forage for supplies.  Later, it became an important grazing area for ranchers in the region. Today, Limestone Canyon remains one of the most pristine wilderness areas in the county and houses a number of habitat restoration projects to further ensure it biological viability. Over 20 miles of trails crisscross Limestone Canyon, providing hiking, riding, and equestrian opportunities for all levels and interests.  You can sign up to participate in a number of activities in Limestone Canyon on LetsGoOutside.org, including Wilderness Access Days.  Be sure to check out all this area has to offer on your next adventure, including:

One of the seven wonders of the Irvine Ranch Natural Landmarks, “The Sinks” in the Limestone Canyon Nature Preserve, is a hidden gem in Orange County. A geological formation consisting of layered sandstone cliffs, The Sinks are often referred to as Orange County’s Mini Grand Canyon and have become a popular destination for outdoor enthusiasts and photographers.
 
The red sandstone cliffs that form The Sinks are eroded in the Sespe Formation, a geological formation of southern California which is between 20-40 million years old. Visitors to The Sinks will experience the beautiful reddish-brown sandstone that drops off sharply into the canyon forming a natural bowl.
