Non-motorized public access is permitted to Sunset Ridge Truck Trail at the eastern perimeter of the RNA and some use of Trail 8W22 has been authorized by permit. Occasional unauthorized access to Trail 8W22 has occurred. This unauthorized use should be monitored but is of insufficient level to warrant further action. Fern Canyon has been the site of large, illegal plantations of marijuana. Periodic surveillance by law enforcement is required to minimize these illegal incursions which otherwise may present a threat to authorized personnel.
Educational use is restricted to individuals at upper-division college level and above.
Proposals for research on the Fern Canyon RNA must be submitted to the SDEF Manager and approved by the PSW Station Director. Permits for research and education and short-term visits may be authorized by the SDEF Manager. Copies of data and reports from research within the RNA are to be transmitted to the SDEF Manager who will maintain a catalog of current studies and available publications. The SDEF Manager will be a point of contact with the ANF for reporting any trespass or other observed violations of forest regulations. Road 1N05 leads to the gauging stations on the Fern Canyon triplicate watersheds and should be maintained as trail access.
