Fire is a natural process in the ponderosa pine forest. Both plants and animals have long been adapted to its presence. However, studies show that the ponderosa pine forest along the north rim of Walnut Canyon has changed considerably during the last century. Prior to 1890, the forest experienced a low-intensity fire every 4 to 8 years, and was composed of fewer, larger pine trees clustered in isolated stands with an open understory of grasses, wildflowers, and non-woody plants. The forest was open and park-like, with a vigorous mix of old and younger plants.

Walnut Canyon has been protected since 1904, first as part of the San Francisco Mountain Reserve (later Coconino National Forest). Early caretakers lived in a log cabin on the canyon rim. Walnut Canyon National Monument was established in 1915, one year before the National Park Service.
