Pinus ponderosa, commonly known as the Ponderosa Pine, Bull Pine, Blackjack Pine, or Western Yellow Pine, is a widespread and variable pine native to western North America. It was first described by David Douglas in 1826, from eastern Washington near present-day Spokane. It is a dominant tree in the Kuchler plant association Ponderosa shrub forest. Like most western pines, the ponderosa is associated with mountainous topography. It is found on the Black Hills and on foothills and mid-height peaks of the northern, central and southern Rocky Mountains as well as the Cascades and Sierra Nevada.
