The Nature Reserve at Rancho Mission Viejo is a growing habitat reserve located in South Orange County. Over time The Nature Reserve will grow to include over 20,000 acres of Rancho Mission Viejo lands, inclusive of The Richard & Donna O’Neill Conservancy. This protected open space is managed by the Rancho Mission Viejo Land Trust, a non-profit 501(c)(3) organization whose mission is to "preserve and enhance Reserve lands for ecological, educational, charitable, conservation, open space, scientific, and recreational uses."

Species Spotlight

The coastal Cactus Wren (Campylorhynchus brunneicapillus) is found only in southern California. These birds have bold marking and harsh rasping call. They feed mostly on insects, some fruits, and seeds. This includes berries and cactus fruits. 
 

This is one of 32 sensitive species covered in our habitat conservation plan, and one of 12 birds on the list “covered species” list. Coastal Cactus Wrens populations have diminished in both size and distribution. This is primarily due to fragmented habitat loss of cactus scrub. On The Nature Reserve, these birds and their populations are scientifically monitored. Additionally, much care is taken to preserve and maintain cactus scrub habitats
