The Biscuit Fire was a massive wildfire in 2002 that burned nearly 500,000 acres (780 sq mi; 2,000 km2) in the Rogue River–Siskiyou National Forest, in southern Oregon and northern California, in the Western United States.

[citation needed] The Biscuit Fire area is subject to warm, dry winds known as the Brookings effect (also known as Chetco effect), driven by high pressure over the Great Basin.

Since the fire, the United States Forest Service has been trying to log most of the severely burnt area, despite ecologists' concerns about the Port Orford Cedar, which is threatened from a root-attacking fungal-like organism that is most commonly spread on car tires and shoes.

This will be the largest recorded timber sale in U.S. history, and a landmark case setting the future for all fires in national forests.

In 2006, a research paper on the effects of post-wildfire salvage logging caused a controversy within the forest sciences community.
