Prescribed fire preparation may include felling trees for firefighter safety or as part of the burn strategy and piling hazardous fuels. Utility task vehicles, chainsaws, and hand tools would be used to support preparation of the project area and prescribed burning activities. If additional control lines are deemed necessary to facilitate safe burning and to protect resources, they will be reviewed by an interdisciplinary team and approved by the deciding official prior to implementation. The interdisciplinary team is made up of NPS fire staff as well as cultural and natural resources staff (including archaeologists, historians, and cultural anthropologists/tribal liaisons). The ignition of the prescribed burn is expected to be accomplished through drip torches. Helicopters or UAVs may be used to assist with the burn if needed.
The Crane Flat Burn Unit prescribed burn project is located at the park's western boundary and lies between two giant sequoia groves (the Tuolumne Grove to the north and the Merced Grove to the south). The area is bounded to the south by the Big Oak Flat Road and to the east by Tioga Road, major park roads providing access to Yosemite Valley and the high-country wilderness area of the park, respectively. The desired forest condition is a landscape that is ecologically healthy and resilient to high intensity fire.
The majority of the PW-05 North Crane Flat unit has burned since 2005. The 2013 Rim Fire burned approximately 20 acres in the northwest section of Segment A between Crane Flat Fire Road and Tioga Road and a few small areas of Segment D along Garnet Ridge Road on the northern boundary. A prescribed burn of 260 acres in 2005 covered much of Segments A and B, excluding the western edge of Segment A and the southeastern finger of Segment B. The 2006 prescribed burn encompassed the southeastern finger of Segment B and all of Segment C, covering approximately 190 acres. In 2010 a prescribed burn was completed on Segment D, covering approximately 210 acres.
