This book was released on 1978 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing systems for estimating site index of ponderosa pine (Pinus ponderosa Laws.) do not apply well to California stands where stocking is controlled. A more suitable system has been developed using trends in natural height growth, derived from stem analyses of dominant trees in California. This site index system produces polymorphic patterns of height development to 80 years of age. Using a second system, site index can be predicted in stands where dominants have reached a breast-height age of at least 4 years but have not attained a height of 20 feet. Accuracy of estimates by this method can be strongly influenced by soil type. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Behavior of visitors on the Rainbow Trail, a Forest Service Interpretive Area in thc Lake Tahoe Basin, California, was surveyed by observation and by interview. Some significant differences between trail visitors and other kinds of outdoor recreation enthusiasts were discovered. Enjoyment was high, and learning, while moderate, exceeded expectations. The Stream Profile Chamber proved to be more significant as an attraction than as an educational tool.
Book Synopsis Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California by : William W. Oliver
Download or read book Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California written by William W. Oliver and published by . This book was released on 1979 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth was strongly related to growing stock level (GSL) for 5 years after thinning 20-year-old poles on Site Index50 115 land at the Elliot Ranch Plantation in northern California. Five GSL's- basal areas anticipated when trees average 10 inches d. b. h. or more - ranging from 40 to 160 square feet per acre were tested. Periodic annual increment (PAI) in diameter decreased curvilinearly from 0.51 to 0.21 inch, with increasing GSL's from 40 to 160. But only trees in plots heavily thinned to GSL 40 (and briefly in GSL 70) grew faster in diameter after thinning than these same trees grew before thinning. PAI in basal area and net volume rose steadily with increasing GSL9s, reaching 9.0 square feet and 255 cubic feet per acre, respectively, at GSL 160. Apparently, even light thinning reduced volume production, but thinning still is recommended to shorten time until first commercial entry and to promote stand health.
