Although ponderosa pine is most common between 6,000 and 9,000 feet, it begins to appear on the landscape around 5,000 feet where prairies and shrublands transition into open ponderosa pine forests. See all years for each photopoint combined at the end of this Journal of Forestry article. Ponderosa pine is typically dominant on warm, dry sites with a short growing season and very low summer precipitation. Scattered stands occur in the Willamette Valley of Oregon and in the Okanagan Valley and Puget Soundareas of Washington. 0000004521 00000 n
The ponderosa pine forest, unlike the lodgepole pine and spruce/fir forests, supports numerous mammal species including Abert's squirrel (Sciurus aberti), which only lives in ponderosa pine communities. 558 0 obj <>

Ponderosa pine is generally the dominant lower timberline species in Colorado’s montane zone. These forests currently are a significant resource for recreation and water supply. It is one of the most abundant conifer species in America and is valued for its rugged-looking and resilient timber as well as for recreational use. Ponderosa pine generally evolved with a natural cycle of frequent, low-intensity fire, which eliminated competing conifer seedlings but allowed mature pines to survive.
