Acorns to Oaks 

Applicant: Rivers & Lands Conservancy 


Project Summary: The Cienega Canyon Preserve, located in San Timoteo Canyon in Calimesa, serves as a valuable natural resource for the surrounding community and wildlife. Since 2012, RLC has organized community-based native oak restoration activities to counteract the loss of oak trees to disease on the 358-acre Preserve. Within five years, approximately 250 volunteers from the communities surrounding the preserve have donated nearly 1,000 hours of service to restore oak woodland habitat.


The IERCD is excited about developing a Master Resource Plan for the Preserve. Over 3,500 residential lots have been approved for construction adjacent to the Preserve, making this place a crucial open space resource for future residents in the rapidly developing area. RLC will work with community stakeholders and government agencies to develop a Master Resource Plan that will plan for the protection of important habitats while creating opportunities for hiking, outdoor programs, education and other forms of passive recreation within the Preserve.
