The 5,224 acre Bishop Creek Prescribed fire is scheduled to begin Friday, September 30, 2011. The primary objective is Wildland Urban Interface Protection. The project will buffer the communities of Yosemite West, Wawona and El Portal, and the Glacier Point Historical District from unwanted wildfire by reducing an over accumulation of fuels.

There are five segments within the unit, and for air quality measures, firefighters will ignite the 1,400 Segment A first, which is estimated to take four to five days to complete. The start of the project will begin with a blackline firing operation at the top of the unit.

It will build off the recent 1,068 acre Avalanche Fire, other prescribed fires and mechanical thinning treatments in Yosemite’s Suppression and Wilderness Fire management Units. The Bishop Creek project is directly adjacent and east of the Wawona Road, and the Avalanche fire to the north. The unit is bisected by the east/west oriented Rail, strawberry and Bishop Creek drainages with a primarily west facing aspect.

The vegetation consists from long needle ponderosa pine/mixed conifer on the lower slopes, to short needle white and red fir mixed conifer further upslope. Pockets of chinquapin, whitethorn, manzanita and bear clover exist. There is an accumulation of other dead and down vegetation, including logs, limbs and other surface fuels.

Since 1930, there have been over 50 suppressed lightning ignitions in the footprint of the Bishop Creek Project. In 1981, there was a 2,100 acre prescribed fire. More recently 100’ to 200’ mechanical fuel treatments breaks and pile burning have occurred along the Wawona Road (Hwy 41). There have been multiple prescribed fuel treatments near the community of Yosemite West (2005 and 2007). Between 1910 and 1926, the area was logged for prized Sugar Pine trees.

Most of the proposed project is within designated wilderness. In accordance with the wilderness Act of 1964, Minimum Impact Management Techniques will be employed top preserve the wilderness integrity. A resource advisor will be assigned to the project to advise on cultural and natural resources. The fall season is preferred implementation period for this project. Fall benefits include fewer impacts to all wildlife, and more complete ground and surface fuel consumption and less resource damage due to post fire mop-up efforts. In all cases, mitigations will be taken to protect sensitive natural and cultural; resources.

Smoke, which can affect health, is always a factor in the decision making process to conduct this and other prescribed fire projects. A smoke management plan has been submitted to the Mariposa County Air Pollution Control District (APCD), and a burn plan has been issued. The Great Basin, Tuolumne Co and the San Joaquin APCDs have been advised of this project. Smoke monitors have been deployed in smoke sensitive areas.

It took me a few seconds to realize this wasn't "my" Bishop Creek smiling smiley

In the 1970's, I always wanted to hike down to the confluence of Bishop Creek and the South Fork of the Merced River. I believe there was a cabin there named Kessler or Koessler, and I heard on one occasion that the builder had installed a water-driven Pelton wheel to generate electricity. Very little information to be found on the topic.
