Excerpt from Lodgepole Pine Clearcut Size Affects Minimum Temperatures Near the Soil Surface The view factor is the fraction of radiation leaving a surface in all directions that is intercepted by another Of concern here is the View factor of a spot on a horizontal surface relative to the Open sky. The greater the View factor for a particular spot, the more closely the net radiation flux of that spot will resemble the net radiation flux of a similar surface in a completely Open area under the same meteorological conditions. View factors were calculated for circular Openings of various widths and for rectangular Openings Of various lengths and widths. View factors were also calculated for spots at various distances from the stand edge for very large clearcuts where the spots were influenced by only one stand edge. The equations used in these calcula tions and their derivations are given in the Appendix. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download Natural Regeneration of Lodgepole Pine in South-central Oregon Book in PDF, ePub and Kindle
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.
