Book Description
Excerpt from Natural Regeneration of Lodgepole Pine in South-Central Oregon This note summarizes information gained from two studies pertinent to the regeneration problem in south - central Oregon and from additional observations made in field and laboratory. One of the studies concerned germination and survival of both lodgepole and ponderosa pine (pinus ponderosa Laws), and the other dealt with lodgepole pine only.

Book Description
A sequence of events is necessary for natural regeneration in the pumice soil region: Adequate seed must be probed and distributed over the area, germination must be favored by warm and moist surface soils, daily surface temperature variation must be moderate, seedlings must survive summer drought, and weather conditions must prevent severe frost heaving the fall after germination and the next spring. This sequence does not always occur within a reasonable time after cutting, and natural regeneration is often delayed. Four possibilities are open to the land manager: (1) declare as noncommercial some severe sites such as lodgepole pine/needlegrass and lodgepole pine/bitterbrush/needlegrass plant communities on flat or basin topography; (2) depend more on a planting program; (3) leave a light slash cover on the surface after shelterwood or narrow strip cutting; and (4) leave a shelterwood on the area after a more thorough slash treatment and be willing to wait much longer than 5 years for natural regeneration. Some problems now exist in obtaining good lodgepole planting stock. Also the slash cover does not guarantee success of natural regeneration and option 3 might turn into option 4.

Book Description
Excerpt from A Ponderosa Pine-Lodgepole Pine Spacing Study in Central Oregon: Results After 20 Years Twenty years after planting, the net volume yield of pure ponderosa pine and pure lodgepole pine at the five spacings reflect the pattern of growth during this time - less wood produced by ponderosa pine at the 6 9 and 12-foot spacings and more wood produced at the 15 and 18-foot spacings when compared to lodgepole pine.

Book Description
Excerpt from Lodgepole Pine in the Blue Mountains of Northeastern Oregon Geologically, the Blue Mountains consist of numerous layers of basalt, which weathers to heavy silts and silty clays. While these soils are often quite fertile chemically, high clay contents tend to create physical conditions unfavorable for tree growth. The soils dry early in the growing season on ridgetops and basalt rims, where erosion has left only a thin (2 to 8 inches) soil mantle.
