The Santa Ana Mountains Natural History Association (SAMNHA) is made up of dedicated volunteers who provide cost-free programs for the general public about natural history features of the Santa Ana Mountains and surrounding wilderness areas located in Southern California. The Santa Ana Mountains Natural History Association is a partner with the Cleveland National Forest in providing these services free of charge to visitors of the Trabuco Ranger District.
The Maple Springs Visitor Center is ready to be staffed. To sign-up as a volunteer, go to the Maple Springs Visitor Center website.
