[Robert F Powers; William W Oliver; Pacific Southwest Forest and Range Experiment Station (Berkeley, Calif.)] -- Existing systems for estimating site index of ponderosa pine (Pinus ponderosa Laws.) do not apply well to California stands where stocking is controlled.
Accordingly, a separate equation is presented for stands on soils formed from skeletal schists. Yield tables based on the first system will be issued separately.

Under. Multiaged Silviculture of Ponderosa Pine—O’Hara a forest under area control regulation but at a smaller scale. O’Hara () questioned these assumptions and concluded that management to maintain these “balanced” stands resulted in lower yields for ponderosa pine and didn’t guarantee sustainability.
Control compartments had the highest stocking followed by burned compartments. In contemporary forest stands, recent treatments involving a combination of burning and thinning resulted in high stocking in height classes 2 and 3.
Overall, the stocking in historical BMEF stands was higher than in contemporary stands and was dominated by ponderosa. In general, thinning appears to reduce attacks by western pine beetle in comparison to unthinned areas. The effects of western pine beetle can be minimized at the stand level by regulating stocking levels in accordance with site-specific stocking guidelines, such as those described by Cochran () and Cochran et al ().

Department of Agriculture, - Agriculture - 96 pages. Ponderosa pine is a species of lean and erect coniferous trees distributed in the western US and Canada. 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.

Associated Forest Cover. Ponderosa pine can be either a climax or a seral species (18,27,47,61). Therefore, we removed ponderosa pine basal area as a predictor from the model construction phase and obtained a second classification tree model.
The second tree used ponderosa pine SDI as the first predictor, with stands with ponderosa pine SDI less or equal to having a probability of infestation of Western yellow pine; Pinus ponderosa; Filed under: Ponderosa pine.

Stand Growth Genetics, Autecology. Conkle () reported on the ponderosa pine elevational study from the Sierra Nevada. In this study, trees from low- mid and high-elevation seed sources were reciprocally planted at these elevations. Progress 10/01/99 to 09/30/04 Outputs Our work in California's mixed-species conifer stands has integrated studies on forest stand dynamics with management implications.
We have developed models that describe the development of stands of redwood and tanoak and stands of sugar pine, ponderosa pine, white fir, incense-cedar, and Douglas-fir.
Early management and control of stocking greatly affects growth and yield of lodgepole pine stands (17). Average annual growth in old-growth unmanaged stands in the central Rocky Mountains only was to m³/ha (about 25 to 40 fbm/acre) because of large numbers of small trees and a high incidence of dwarf mistletoe (4).
Habitat: Ponderosa pine trees occur as pure stands or in mixed conifer forests in the mountains. It is an important component of the Interior Ponderosa Pine, Pacific Ponderosa Pine-Douglas fir, and Pacific Ponderosa Pine forest cover types.
In the northwest, it is typically associated with Rocky Mountain Douglas fir, lodgepole pine, grand fir, and. Powers RF, Oliver WW () Site classification under stocking control in California.

You usually do not find grass doing well under large ponderosa pines, particularly on shallow soils but there are plants that thrive in this protected environment. My favorite ground cover for pine is bearberry (Arctostaphylos uva-ursi), This is an evergreen ground cover that reaches a height of 4 inches and a single plant can spread 2 to 3 feet.
