Investigators have determined that the 11,000-acre Dodge fire, burning 70 miles northeast of Susanville, was started by a spark from logging equipment.
A private contractor was harvesting trees with a feller-buncher on Monday when a spark from the spinning blade set fire to dry grass, said Jeff Fontana, a spokesman for the Bureau of Land Management in Susanville.
The fire spread quickly into tall sagebrush and juniper, important habitat for greater sage grouse, wild horses and burros.
Officials are continuing their investigation to determine whether there was negligence, said Nancy Haug, the agency’s district manager for Northern California.
Never miss a local story.
The fire is threatening a few isolated ranch cabins but had not damaged any by late Wednesday, when Fontana said it was 20 percent contained.
